jdwglib Developer's Guide |
|

|
|
3 |
Overview |
|
4 |
|
|
5 |
The Java DWG Library (jdwglib) is a Java libray designed for reading, handling and |
|
6 |
writing drawing files in the Autodesk DWG format. This document is the design |
|
7 |
specification for the classes, methods and algorithms implemented in the Java DWG |
|
8 |
Library. |
|
9 |
|
|
10 |
jdwglib has two different parts, first for DWG file accesing, and second for DWG file |
|
11 |
handling. The part for accesing DWG files support the reading of DWG files and in |
|
12 |
future versions we hope that writing of DWG files will be supported too. The part for |
|
13 |
handling DWG files is designed for managing DWG complex objects like polylines or |
|
14 |
blocks with the objective that the spatial position and the attributes of DWG objects |
|
15 |
will be definitive and no one operation is required for obtaining the same results |
|
16 |
that Autocad. |
|
17 |
|
|
18 |
The detailed documentation of the class hierarchy and methods will be presented in the |
|
19 |
form of JavaDoc for the source code. |
|

Other resources |
|
23 |
|
|
24 |
- Pythoncad DWG Library by Art Haas (www.pythoncad.org). The part of jdwglib that reads |
|
25 |
DWG files is a port of this library with an object oriented model added. |
|
26 |
|
|
27 |
- The AutoCAD R13/R14/R2000 DWG File Specification by the OpenDWG Alliance. This is the |
|
28 |
public specification of the DWG format obtained using reverse engineering methods by |
|
29 |
the OpenDWG Alliance (www.opendwg.org). |
|
30 |
|
|
31 |
|
|
32 |
Handling DWG files |
|
33 |
|
|
34 |
jdwglib has been developed to allow GPL GIS applications to handle the information |
|
35 |
stored in DWG files. |
|
36 |
|
|
37 |
jdwglib has been designed to allow developers to create DWG drivers for their |
|
38 |
CAD/GIS applications easily and in a GPL environment. |
|
39 |
|
|
40 |
The use of jdwglib for any driver is ever the same: |
|
41 |
|
|
42 |
- DwgFile dwgFile = new DwgFile(dwg.getAbsolutePath()); Creates a new DwgFile |
|
43 |
object for reading a DWG file. |
|
44 |
|
|
45 |
- dwgFile.read(); Reads the DWG file but don't configure its objects. |
|
46 |
|
|
47 |
- dwgFile.initializeLayerTable(); Creates a table with the DWG file layer |
|
48 |
information. |
|
49 |
|
|
50 |
- dwgFile.calculateGisModelDwgPolylines() or dwgFile.calculateCadModelDwgPolylines(); |
|
51 |
calculateGisModelDwgPolylines() configures Polyline's geometry. In Polylines with |
|
52 |
arcs, these arcs are defined by a set of points and a distance between these points. |
|
53 |
calculateCadModelDwgPolylines() configures Polyline's geometry. In Polylines with |
|
54 |
arcs, these arcs are defined by a curvature parameter called bulge that is associated |
|
55 |
with the points. |
|
56 |
|
|
57 |
- dwgFile.applyExtrusions(); The extrusion parameters of the objets in a DWG file |
|
58 |
changes the location of these objects. |
|
59 |
|
|
60 |
- dwgFile.testDwg3D(): test if the DWG file has elevation information. |
|
61 |
|
|
62 |
- dwgFile.blockManagement(); This method manages the blocks contained in a DWG file. |
|
63 |
|
|
64 |
- Vector dwgObjects = dwgFile.getDwgObjects(); Import the set of DWG objects. Now they |
|
65 |
are correctly configured. |
|
66 |
|
|
67 |
- for (int i=0;i<dwgObjects.size();i++) { |
|
68 |
DwgObject iObj = (DwgObject)dwgObjects.get(i); |
|
69 |
if (iObj instanceof DwgArc) { |
|
70 |
//Convert iObj to the corresponding object model |
|
71 |
} |
|
72 |
} Convert DWG objects to the corresponding object model. |
|
73 |
|
|
74 |
- String layerName = dwgFile.getLayerName(iObj); Returns the layer name of a DWG |
|
75 |
object. |
|
76 |
|
|
77 |
- int colorByLayer = dwgFile.getColorByLayer(iObj); Returns color of the layer of a |
|
78 |
DWG object. |
|
79 |
|
|
80 |
The author has implemented a DWG driver for gvSIG based on this library, and a DWG |
|
81 |
driver for other Java GIS application like Jump or uDig must be easy to implement too. |

GNU GENERAL PUBLIC LICENSE |
|

Version 2, June 1991 |
|

|
|
4 |
Copyright (C) 1989, 1991 Free Software Foundation, Inc. |
|
5 |
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
|
6 |
Everyone is permitted to copy and distribute verbatim copies |
|
7 |
of this license document, but changing it is not allowed. |
|
8 |
|
|
9 |
Preamble |
|
10 |
|
|
11 |
The licenses for most software are designed to take away your |
|
12 |
freedom to share and change it. By contrast, the GNU General Public |
|
13 |
License is intended to guarantee your freedom to share and change free |
|
14 |
software--to make sure the software is free for all its users. This |
|
15 |
General Public License applies to most of the Free Software |
|
16 |
Foundation's software and to any other program whose authors commit to |
|
17 |
using it. (Some other Free Software Foundation software is covered by |
|
18 |
the GNU Library General Public License instead.) You can apply it to |
|
19 |
your programs, too. |
|
20 |
|
|
21 |
When we speak of free software, we are referring to freedom, not |
|
22 |
price. Our General Public Licenses are designed to make sure that you |
|
23 |
have the freedom to distribute copies of free software (and charge for |
|
24 |
this service if you wish), that you receive source code or can get it |
|
25 |
if you want it, that you can change the software or use pieces of it |
|
26 |
in new free programs; and that you know you can do these things. |
|
27 |
|
|
28 |
To protect your rights, we need to make restrictions that forbid |
|
29 |
anyone to deny you these rights or to ask you to surrender the rights. |
|
30 |
These restrictions translate to certain responsibilities for you if you |
|
31 |
distribute copies of the software, or if you modify it. |
|
32 |
|
|
33 |
For example, if you distribute copies of such a program, whether |
|
34 |
gratis or for a fee, you must give the recipients all the rights that |
|
35 |
you have. You must make sure that they, too, receive or can get the |
|
36 |
source code. And you must show them these terms so they know their |
|
37 |
rights. |
|
38 |
|
|
39 |
We protect your rights with two steps: (1) copyright the software, and |
|
40 |
(2) offer you this license which gives you legal permission to copy, |
|
41 |
distribute and/or modify the software. |
|
42 |
|
|
43 |
Also, for each author's protection and ours, we want to make certain |
|
44 |
that everyone understands that there is no warranty for this free |
|
45 |
software. If the software is modified by someone else and passed on, we |
|
46 |
want its recipients to know that what they have is not the original, so |
|
47 |
that any problems introduced by others will not reflect on the original |
|
48 |
authors' reputations. |
|
49 |
|
|
50 |
Finally, any free program is threatened constantly by software |
|
51 |
patents. We wish to avoid the danger that redistributors of a free |
|
52 |
program will individually obtain patent licenses, in effect making the |
|
53 |
program proprietary. To prevent this, we have made it clear that any |
|
54 |
patent must be licensed for everyone's free use or not licensed at all. |
|
55 |
|
|
56 |
The precise terms and conditions for copying, distribution and |
|
57 |
modification follow. |
|
58 |
|
|
59 |
GNU GENERAL PUBLIC LICENSE |
|
60 |
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|
61 |
|
|
62 |
0. This License applies to any program or other work which contains |
|
63 |
a notice placed by the copyright holder saying it may be distributed |
|
64 |
under the terms of this General Public License. The "Program", below, |
|
65 |
refers to any such program or work, and a "work based on the Program" |
|
66 |
means either the Program or any derivative work under copyright law: |
|
67 |
that is to say, a work containing the Program or a portion of it, |
|
68 |
either verbatim or with modifications and/or translated into another |
|
69 |
language. (Hereinafter, translation is included without limitation in |
|
70 |
the term "modification".) Each licensee is addressed as "you". |
|
71 |
|
|
72 |
Activities other than copying, distribution and modification are not |
|
73 |
covered by this License; they are outside its scope. The act of |
|
74 |
running the Program is not restricted, and the output from the Program |
|
75 |
is covered only if its contents constitute a work based on the |
|
76 |
Program (independent of having been made by running the Program). |
|
77 |
Whether that is true depends on what the Program does. |
|
78 |
|
|
79 |
1. You may copy and distribute verbatim copies of the Program's |
|
80 |
source code as you receive it, in any medium, provided that you |
|
81 |
conspicuously and appropriately publish on each copy an appropriate |
|
82 |
copyright notice and disclaimer of warranty; keep intact all the |
|
83 |
notices that refer to this License and to the absence of any warranty; |
|
84 |
and give any other recipients of the Program a copy of this License |
|
85 |
along with the Program. |
|
86 |
|
|
87 |
You may charge a fee for the physical act of transferring a copy, and |
|
88 |
you may at your option offer warranty protection in exchange for a fee. |
|
89 |
|
|
90 |
2. You may modify your copy or copies of the Program or any portion |
|
91 |
of it, thus forming a work based on the Program, and copy and |
|
92 |
distribute such modifications or work under the terms of Section 1 |
|
93 |
above, provided that you also meet all of these conditions: |
|
94 |
|
|
95 |
a) You must cause the modified files to carry prominent notices |
|
96 |
stating that you changed the files and the date of any change. |
|
97 |
|
|
98 |
b) You must cause any work that you distribute or publish, that in |
|
99 |
whole or in part contains or is derived from the Program or any |
|
100 |
part thereof, to be licensed as a whole at no charge to all third |
|
101 |
parties under the terms of this License. |
|
102 |
|
|
103 |
c) If the modified program normally reads commands interactively |
|
104 |
when run, you must cause it, when started running for such |
|
105 |
interactive use in the most ordinary way, to print or display an |
|
106 |
announcement including an appropriate copyright notice and a |
|
107 |
notice that there is no warranty (or else, saying that you provide |
|
108 |
a warranty) and that users may redistribute the program under |
|
109 |
these conditions, and telling the user how to view a copy of this |
|
110 |
License. (Exception: if the Program itself is interactive but |
|
111 |
does not normally print such an announcement, your work based on |
|
112 |
the Program is not required to print an announcement.) |
|
113 |
|
|
114 |
These requirements apply to the modified work as a whole. If |
|
115 |
identifiable sections of that work are not derived from the Program, |
|
116 |
and can be reasonably considered independent and separate works in |
|
117 |
themselves, then this License, and its terms, do not apply to those |
|
118 |
sections when you distribute them as separate works. But when you |
|
119 |
distribute the same sections as part of a whole which is a work based |
|
120 |
on the Program, the distribution of the whole must be on the terms of |
|
121 |
this License, whose permissions for other licensees extend to the |
|
122 |
entire whole, and thus to each and every part regardless of who wrote it. |
|
123 |
|
|
124 |
Thus, it is not the intent of this section to claim rights or contest |
|
125 |
your rights to work written entirely by you; rather, the intent is to |
|
126 |
exercise the right to control the distribution of derivative or |
|
127 |
collective works based on the Program. |
|
128 |
|
|
129 |
In addition, mere aggregation of another work not based on the Program |
|
130 |
with the Program (or with a work based on the Program) on a volume of |
|
131 |
a storage or distribution medium does not bring the other work under |
|
132 |
the scope of this License. |
|
133 |
|
|
134 |
3. You may copy and distribute the Program (or a work based on it, |
|
135 |
under Section 2) in object code or executable form under the terms of |
|
136 |
Sections 1 and 2 above provided that you also do one of the following: |
|
137 |
|
|
138 |
a) Accompany it with the complete corresponding machine-readable |
|
139 |
source code, which must be distributed under the terms of Sections |
|
140 |
1 and 2 above on a medium customarily used for software interchange; or, |
|
141 |
|
|
142 |
b) Accompany it with a written offer, valid for at least three |
|
143 |
years, to give any third party, for a charge no more than your |
|
144 |
cost of physically performing source distribution, a complete |
|
145 |
machine-readable copy of the corresponding source code, to be |
|
146 |
distributed under the terms of Sections 1 and 2 above on a medium |
|
147 |
customarily used for software interchange; or, |
|
148 |
|
|
149 |
c) Accompany it with the information you received as to the offer |
|
150 |
to distribute corresponding source code. (This alternative is |
|
151 |
allowed only for noncommercial distribution and only if you |
|
152 |
received the program in object code or executable form with such |
|
153 |
an offer, in accord with Subsection b above.) |
|
154 |
|
|
155 |
The source code for a work means the preferred form of the work for |
|
156 |
making modifications to it. For an executable work, complete source |
|
157 |
code means all the source code for all modules it contains, plus any |
|
158 |
associated interface definition files, plus the scripts used to |
|
159 |
control compilation and installation of the executable. However, as a |
|
160 |
special exception, the source code distributed need not include |
|
161 |
anything that is normally distributed (in either source or binary |
|
162 |
form) with the major components (compiler, kernel, and so on) of the |
|
163 |
operating system on which the executable runs, unless that component |
|
164 |
itself accompanies the executable. |
|
165 |
|
|
166 |
If distribution of executable or object code is made by offering |
|
167 |
access to copy from a designated place, then offering equivalent |
|
168 |
access to copy the source code from the same place counts as |
|
169 |
distribution of the source code, even though third parties are not |
|
170 |
compelled to copy the source along with the object code. |
|
171 |
|
|
172 |
4. You may not copy, modify, sublicense, or distribute the Program |
|
173 |
except as expressly provided under this License. Any attempt |
|
174 |
otherwise to copy, modify, sublicense or distribute the Program is |
|
175 |
void, and will automatically terminate your rights under this License. |
|
176 |
However, parties who have received copies, or rights, from you under |
|
177 |
this License will not have their licenses terminated so long as such |
|
178 |
parties remain in full compliance. |
|
179 |
|
|
180 |
5. You are not required to accept this License, since you have not |
|
181 |
signed it. However, nothing else grants you permission to modify or |
|
182 |
distribute the Program or its derivative works. These actions are |
|
183 |
prohibited by law if you do not accept this License. Therefore, by |
|
184 |
modifying or distributing the Program (or any work based on the |
|
185 |
Program), you indicate your acceptance of this License to do so, and |
|
186 |
all its terms and conditions for copying, distributing or modifying |
|
187 |
the Program or works based on it. |
|
188 |
|
|
189 |
6. Each time you redistribute the Program (or any work based on the |
|
190 |
Program), the recipient automatically receives a license from the |
|
191 |
original licensor to copy, distribute or modify the Program subject to |
|
192 |
these terms and conditions. You may not impose any further |
|
193 |
restrictions on the recipients' exercise of the rights granted herein. |
|
194 |
You are not responsible for enforcing compliance by third parties to |
|
195 |
this License. |
|
196 |
|
|
197 |
7. If, as a consequence of a court judgment or allegation of patent |
|
198 |
infringement or for any other reason (not limited to patent issues), |
|
199 |
conditions are imposed on you (whether by court order, agreement or |
|
200 |
otherwise) that contradict the conditions of this License, they do not |
|
201 |
excuse you from the conditions of this License. If you cannot |
|
202 |
distribute so as to satisfy simultaneously your obligations under this |
|
203 |
License and any other pertinent obligations, then as a consequence you |
|
204 |
may not distribute the Program at all. For example, if a patent |
|
205 |
license would not permit royalty-free redistribution of the Program by |
|
206 |
all those who receive copies directly or indirectly through you, then |
|
207 |
the only way you could satisfy both it and this License would be to |
|
208 |
refrain entirely from distribution of the Program. |
|
209 |
|
|
210 |
If any portion of this section is held invalid or unenforceable under |
|
211 |
any particular circumstance, the balance of the section is intended to |
|
212 |
apply and the section as a whole is intended to apply in other |
|
213 |
circumstances. |
|
214 |
|
|
215 |
It is not the purpose of this section to induce you to infringe any |
|
216 |
patents or other property right claims or to contest validity of any |
|
217 |
such claims; this section has the sole purpose of protecting the |
|
218 |
integrity of the free software distribution system, which is |
|
219 |
implemented by public license practices. Many people have made |
|
220 |
generous contributions to the wide range of software distributed |
|
221 |
through that system in reliance on consistent application of that |
|
222 |
system; it is up to the author/donor to decide if he or she is willing |
|
223 |
to distribute software through any other system and a licensee cannot |
|
224 |
impose that choice. |
|
225 |
|
|
226 |
This section is intended to make thoroughly clear what is believed to |
|
227 |
be a consequence of the rest of this License. |
|
228 |
|
|
229 |
8. If the distribution and/or use of the Program is restricted in |
|
230 |
certain countries either by patents or by copyrighted interfaces, the |
|
231 |
original copyright holder who places the Program under this License |
|
232 |
may add an explicit geographical distribution limitation excluding |
|
233 |
those countries, so that distribution is permitted only in or among |
|
234 |
countries not thus excluded. In such case, this License incorporates |
|
235 |
the limitation as if written in the body of this License. |
|
236 |
|
|
237 |
9. The Free Software Foundation may publish revised and/or new versions |
|
238 |
of the General Public License from time to time. Such new versions will |
|
239 |
be similar in spirit to the present version, but may differ in detail to |
|
240 |
address new problems or concerns. |
|
241 |
|
|
242 |
Each version is given a distinguishing version number. If the Program |
|
243 |
specifies a version number of this License which applies to it and "any |
|
244 |
later version", you have the option of following the terms and conditions |
|
245 |
either of that version or of any later version published by the Free |
|
246 |
Software Foundation. If the Program does not specify a version number of |
|
247 |
this License, you may choose any version ever published by the Free Software |
|
248 |
Foundation. |
|
249 |
|
|
250 |
10. If you wish to incorporate parts of the Program into other free |
|
251 |
programs whose distribution conditions are different, write to the author |
|
252 |
to ask for permission. For software which is copyrighted by the Free |
|
253 |
Software Foundation, write to the Free Software Foundation; we sometimes |
|
254 |
make exceptions for this. Our decision will be guided by the two goals |
|
255 |
of preserving the free status of all derivatives of our free software and |
|
256 |
of promoting the sharing and reuse of software generally. |
|
257 |
|
|
258 |
NO WARRANTY |
|
259 |
|
|
260 |
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|
261 |
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|
262 |
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|
263 |
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|
264 |
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|
265 |
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|
266 |
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|
267 |
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|
268 |
REPAIR OR CORRECTION. |
|
269 |
|
|
270 |
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
271 |
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|
272 |
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|
273 |
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|
274 |
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|
275 |
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|
276 |
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|
277 |
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|
278 |
POSSIBILITY OF SUCH DAMAGES. |
|
279 |
|
|
280 |
END OF TERMS AND CONDITIONS |
|
281 |
|
|
282 |
How to Apply These Terms to Your New Programs |
|
283 |
|
|
284 |
If you develop a new program, and you want it to be of the greatest |
|
285 |
possible use to the public, the best way to achieve this is to make it |
|
286 |
free software which everyone can redistribute and change under these terms. |
|
287 |
|
|
288 |
To do so, attach the following notices to the program. It is safest |
|
289 |
to attach them to the start of each source file to most effectively |
|
290 |
convey the exclusion of warranty; and each file should have at least |
|
291 |
the "copyright" line and a pointer to where the full notice is found. |
|
292 |
|
|
293 |
<one line to give the program's name and a brief idea of what it does.> |
|
294 |
Copyright (C) <year> <name of author> |
|
295 |
|
|
296 |
This program is free software; you can redistribute it and/or modify |
|
297 |
it under the terms of the GNU General Public License as published by |
|
298 |
the Free Software Foundation; either version 2 of the License, or |
|
299 |
(at your option) any later version. |
|
300 |
|
|
301 |
This program is distributed in the hope that it will be useful, |
|
302 |
but WITHOUT ANY WARRANTY; without even the implied warranty of |
|
303 |
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|
304 |
GNU General Public License for more details. |
|
305 |
|
|
306 |
You should have received a copy of the GNU General Public License |
|
307 |
along with this program; if not, write to the Free Software |
|
308 |
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
|
309 |
|
|
310 |
|
|
311 |
Also add information on how to contact you by electronic and paper mail. |
|
312 |
|
|
313 |
If the program is interactive, make it output a short notice like this |
|
314 |
when it starts in an interactive mode: |
|
315 |
|
|
316 |
Gnomovision version 69, Copyright (C) year name of author |
|
317 |
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|
318 |
This is free software, and you are welcome to redistribute it |
|
319 |
under certain conditions; type `show c' for details. |
|
320 |
|
|
321 |
The hypothetical commands `show w' and `show c' should show the appropriate |
|
322 |
parts of the General Public License. Of course, the commands you use may |
|
323 |
be called something other than `show w' and `show c'; they could even be |
|
324 |
mouse-clicks or menu items--whatever suits your program. |
|
325 |
|
|
326 |
You should also get your employer (if you work as a programmer) or your |
|
327 |
school, if any, to sign a "copyright disclaimer" for the program, if |
|
328 |
necessary. Here is a sample; alter the names: |
|
329 |
|
|
330 |
Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
|
331 |
`Gnomovision' (which makes passes at compilers) written by James Hacker. |

336 |
This General Public License does not permit incorporating your program into |
|
337 |
proprietary programs. If your program is a subroutine library, you may |
|
338 |
consider it more useful to permit linking proprietary applications with the |
|
339 |
library. If this is what you want to do, use the GNU Library General |
|
340 |
Public License instead of this License. |

Alternativas |
|
9 |
|
|
10 |
Librer?as OpenDWG |
|
11 |
|
|
12 |
Ventajas |
|
13 |
|
|
14 |
- Soporte del formato DWG de la m?s alta calidad garantizado |
|
15 |
|
|
16 |
- Permite tanto lectura como escritura |
|
17 |
|
|
18 |
- Todas las versiones est?n soportadas |
|
19 |
|
|
20 |
- OpenDWG tiene gran capacidad de desarrollo |
|
21 |
|
|
22 |
Inconvenientes |
|
23 |
|
|
24 |
- Est? en C y es necesario un acceso JNI |
|
25 |
|
|
26 |
- Una empresa que de un uso comercial a gvSIG debe pagar a OpenDWG por sus |
|
27 |
librer?as |
|
28 |
|
|
29 |
- Un usuario que no de un uso comercial a gvSIG debe mandar un contrato |
|
30 |
firmado a la OpenDWG |
|
31 |
|
|
32 |
- OpenDWG puede decidir no facilitar sus librer?as |
|
33 |
|
|
34 |
- OpenDWG en la pr?ctica no tiene ninguna obligaci?n para con sus |
|
35 |
usuarios |
|
36 |
|
|
37 |
Acceso v?a jython a la librer?a de DWG en Python de Art Haas |
|
38 |
|
|
39 |
Ventajas |
|
40 |
|
|
41 |
- M?xima reutilizaci?n de la librer?a original de Art Haas |
|
42 |
|
|
43 |
- Facilidad a la hora de incorporar nuevas versiones de la librer?a original |
|
44 |
|
|
45 |
Inconvenientes |
|
46 |
|
|
47 |
- Incremento muy muy considerable de la complejidad del c?digo |
|
48 |
|
|
49 |
- Ralentizaci?n de la librer?a |
|
50 |
|
|
51 |
- Grandes dificultades para realizar cambios en el c?digo |
|
52 |
|
|
53 |
- Es posible que Art no vaya a sacar nuevas versiones de esta librer?a |
|
54 |
|
|
55 |
- La librer?a de Art no est? orientada a objetos. La propia opini?n de Art es |
|
56 |
que la mejor opci?n es el porting dotando a la nueva librer?a de orientaci?n |
|
57 |
a objetos |
|
58 |
|
|
59 |
Port a Java de la librer?a de DWG en Python de Art Haas |

- Si se publica la librer?a quiz? se logre la colaboraci?n de otros |
|
68 |
desarrolladores |
|
69 |
|
|
70 |
- Art Haas no descarta la posibilidad de implementar la escritura de DWG |
|
71 |
|
|
72 |
Inconvenientes |
|
73 |
|
|
74 |
- Hoy por hoy no existe colaboraci?n en este sentido por parte de la |
|
75 |
OpenDWG, ni por parte de Art Haas (desarrollador de la librer?a en python |
|
76 |
de lectura de DWG) |
|
77 |
|
|
78 |
- La especificaci?n de la OpenDWG tiene errores que no piensan resolver |
|
79 |

108 |
Maqueando jdwglib v0.1 y su driver para gvSIG |
|
109 |
|
|
110 |
|
|
111 |
Perspectivas |
|
112 |
|
|
113 |
Mientras no cambie la pol?tica (y no creo que eso suceda) de la OpenDWG, la gesti?n de |
|
114 |
informaci?n contenida en ficheros DWG a trav?s de su librer?a ser? propietaria y de |
|
115 |
pago. La ventaja de su utilizaci?n es su potencia. Representa el camino r?pido y |
|
116 |
sencillo |
|
117 |
|
|
118 |
jdwglib se ajusta a los requisitos exijidos en el pliego para gvSIG y adem?s constituye |
|
119 |
la primera librer?a libre de lectura de ficheros DWG en Java. Para lograr que la |
|
120 |
lectura de DWG a trav?s de esta librer?a sea tan efectiva como la de DXF, tan solo |
|
121 |
hay que solucionar los bugs conocidos. Para ello ser?a de gran ayuda la publicaci?n de |
|
122 |
la librer?a y la colaboraci?n de la comunidad en el desarrollo. Sobre este tema habr?a |
|
123 |
que discutir cuando es buen momento para la publicaci?n, puesto que esta librer?a podr?a |
|
124 |
ser aprovechada por ProDevelop para mejorar su oferta de CAD |
|
125 |
|
|
126 |
Con ayuda de la comunidad los objetivos pueden cumplirse en un plazo breve, quiz? un |
|
127 |
mes. Sin ayuda, el proceso de depuraci?n de la librer?a puede prolongarse m?s y hasta |
|
128 |
es posible que no se consigan eliminar todos los bugs |
|

The Java DWG Library (jdwglib) is a Java libray designed for reading, handling and |
|
6 |
writing drawing files in the Autodesk DWG format. This document is the design |
|
7 |
specification for the classes, methods and algorithms implemented in the Java DWG |
|
8 |
Library. |
|
9 |
|
|
10 |
jdwglib has two different parts, first for DWG file accesing, and second for DWG file |
|
11 |
handling. The part for accesing DWG files support the reading of DWG files and in |
|
12 |
future versions we hope that writing of DWG files will be supported too. The part for |
|
13 |
handling DWG files is designed for managing DWG complex objects like polylines or |
|
14 |
blocks with the objective that the spatial position and the attributes of DWG objects |
|
15 |
will be definitive and no one operation is required for obtaining the same results |
|
16 |
that Autocad. |
|
17 |
|
|
18 |
The detailed documentation of the class hierarchy and methods will be presented in the |
|
19 |
form of JavaDoc for the source code. |

- Pythoncad DWG Library by Art Haas (www.pythoncad.org). The part of jdwglib that reads |
|
25 |
DWG files is a port of this library with an object oriented model added. |
|
26 |
|
|
27 |
- The AutoCAD R13/R14/R2000 DWG File Specification by the OpenDWG Alliance. This is the |
|
28 |
public specification of the DWG format obtained using reverse engineering methods by |
|
29 |
the OpenDWG Alliance (www.opendwg.org). |

Design goals |
|
33 |
|
|
34 |
The design of jdwglib is intended to fulfil the following goals: |
|
35 |
|
|
36 |
- jdwglib must return the definitive set of DWG objects. Geometric and |
|
37 |
non geometric attributes of these objects will be enough for its correct and complete |
|
38 |
representation. |
|
39 |
|
|
40 |
- The jdwglib interface must be easy to use, even by someone that hasn't advanced |
|
41 |
CAD knowledge. |
|
42 |
|
|
43 |
- jdwglib will be fast enough to be used in a production environment. |
|
44 |
|
|
45 |
- The algorithms and code used in jdwglib will be clear and well-structured, to |
|
46 |
facilitate understanding by other developers. |

Object model |
|
50 |
|
|
51 |
The package javacad.util contains some general classes that are useful for handling |
|
52 |
DWG objects and other objects in a GIS environment. Their use is described in the |
|
53 |
JavaDoc documentation. |
|
54 |
|
|
55 |
The package jdwglib contains the classes for reading and managing DWG files and its |
|
56 |
objects. Their use is described in the JavaDoc documentation. |

How This API Document Is Organized</H1> |
|
78 |
</CENTER> |
|
79 |
This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3> |
|
80 |
Overview</H3> |
|
81 |
<BLOCKQUOTE> |
|
82 |
|
|
83 |
<P> |
|
84 |
The <A HREF="overview-summary.html">Overview</A> page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.</BLOCKQUOTE> |
|
85 |
<H3> |
|
86 |
Package</H3> |
|
87 |
<BLOCKQUOTE> |
|
88 |
|
|
89 |
<P> |
|
90 |
Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL> |
|
91 |
<LI>Interfaces (italic)<LI>Classes<LI>Exceptions<LI>Errors</UL> |
|
92 |
</BLOCKQUOTE> |
|
93 |
<H3> |
|
94 |
Class/Interface</H3> |
|
95 |
<BLOCKQUOTE> |
|
96 |
|
|
97 |
<P> |
|
98 |
Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL> |
|
99 |
<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description |
|
100 |
<P> |
|
101 |
<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary |
|
102 |
<P> |
|
103 |
<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL> |
|
104 |
Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE> |
|
105 |
<H3> |
|
106 |
Use</H3> |
|
107 |
<BLOCKQUOTE> |
|
108 |
Each documented package, class and interface has its own Use page. This page describes what packages, classes, methods, constructors and fields use any part of the given class or package. Given a class or interface A, its Use page includes subclasses of A, fields declared as A, methods that return A, and methods and constructors with parameters of type A. You can access this page by first going to the package, class or interface, then clicking on the "Use" link in the navigation bar.</BLOCKQUOTE> |
|
109 |
<H3> |
|
110 |
Tree (Class Hierarchy)</H3> |
|
111 |
<BLOCKQUOTE> |
|
112 |
There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL> |
|
113 |
<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL> |
|
114 |
</BLOCKQUOTE> |
|
115 |
<H3> |
|
116 |
Deprecated API</H3> |
|
117 |
<BLOCKQUOTE> |
|
118 |
The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE> |
|
119 |
<H3> |
|
120 |
Index</H3> |
|
121 |
<BLOCKQUOTE> |
|
122 |
The <A HREF="index-files/index-1.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE> |
|
123 |
<H3> |
|
124 |
Prev/Next</H3> |
|
125 |
These links take you to the next or previous class, interface, package, or related page.<H3> |
|
126 |
Frames/No Frames</H3> |
|
127 |
These links show and hide the HTML frames. All pages are available with or without frames. |
|
128 |
<P> |
|
129 |
<H3> |
|
130 |
Serialized Form</H3> |
|
131 |
Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description. |
