/*

** The EcwCompressionTask is used to simply do compressions.
|
42 |
**
|
43 |
** Usage is:
|
44 |
** ecw_compress_task_new() - to create one of these structures
|
45 |
** ecw_compress_task_parse_args() - (optional step) parse command line args into task structure
|
46 |
** ecw_compress_task_setup() - will open input, and compute size details
|
47 |
** ecw_compress_task_compress() - do the actional compression. Skip this step to just get file sizes
|
48 |
** ecw_compress_task_delete() - to close the structure and any associated data
