I would like to propose the following initial list of compressions for
raster objects:
PCL5 - the compression methods as defined by the PCL5 spec (uncompressed,
RLE, TIFF, delta row, adaptive)
PCL6 - the compression methods as defined by the PCL6 level 1.1 spec
(uncompressed, RLE)
PCL6_JPEG - the JPEG compression method as defined by the PCL6 level 2.0 spec
PCL6_DELTAROW - the delta row compression method as defined by the PCL6
level 2.1 spec
PS - the compression methods as defined by the PostScript level 2 spec
(uncompressed, RLE, JPEG)
PS_LZW - the LZW compression method as defined by the PostScript level 2 spec
PS_FLATE - the Flate compression method as defined by the PostScript level
3 spec
JPEG - standard JPEG compression in JFIF format
JBIG2 - standard JBIG2 compression
FAX_G3 - CCITT Group 3 fax compression
FAX_G4 - CCITT Group 4 fax compression
If anyone knows of any other compression methods that are commonly used by
printers we can certainly add them.
Jim
