JPEG processes are supported. (Our subset includes all features now in common
use.) Unsupported ISO options include:
* Hierarchical storage
- * Lossless JPEG
* Arithmetic entropy coding (unsupported for legal reasons)
* DNL marker
* Nonintegral subsampling ratios
unless you want to make a custom scan sequence. You must ensure that
the JPEG color space is set correctly before calling this routine.
+jpeg_simple_lossless (j_compress_ptr cinfo, int predictor, int point_transform)
+ Generates a default scan script for writing a lossless-JPEG file.
+ This is the recommended method of creating a lossless file,
+ unless you want to make a custom scan sequence. You must ensure that
