Class TextPath

java.lang.Object

org.gvsig.symbology.fmap.mapcontext.rendering.legend.styling.TextPath

public class TextPath
extends Object

Class that represents baseline of a string and allows the baseline to be composed as contiguous segments with distinct slope each.

Once a TextPath is created for a string it is possible to know where the character at a determined position in the string is placed and rotated.

Constructor Details

TextPath

public TextPath(Graphics2D g,
 org.gvsig.fmap.geom.Geometry path,
 char[] text,
 Font font,
 float characterSpacing,
 float characterWidth,
 boolean kerning,
 float leading,
 int alignment,
 float wordSpacing,
 float margin,
 boolean rightToLeft)

Creates a new instance of TextPath with the current graphics context.

Given a Graphics2D, TextPath can know which Font and FontRenderContext is in use. So, it can calculate the position and rotation of each character in char[] text based in the path defined by the FShape path argument.

Parameters:

g - , Graphics2D

path - , FShape

text - , char[]

Method Details

softenShape

protected org.gvsig.fmap.geom.Geometry softenShape(org.gvsig.fmap.geom.Geometry shape,
 GlyphVector gv)
                                            throws org.gvsig.fmap.geom.exception.CreateGeometryException

Throws:

org.gvsig.fmap.geom.exception.CreateGeometryException

nextPosForGlyph

public double[] nextPosForGlyph(int glyphIndex)

Returns the placement of the next character to draw and the corresponding rotation in a double array of three elements with this order:

double[0] Position in X in the screen

double[1] Position in Y in the screen

double[2] Angle of the character.

Returns:

getGlyphCount

public int getGlyphCount()

isWordSeparator

protected static boolean isWordSeparator(char c,
 char[] wordSeparators)
