1005 | * The current implementation locally-decodes the raster data and then writes | |
1006 | * whole, non-blank lines as 1-line high images with base-85 encoding, resulting | |
1007 | * in between 10 and 20 times larger output. A alternate implementation (if it | |
1008 | * is deemed necessary) would be to implement a PostScript decode procedure that | |
1009 | * handles the modified packbits decompression so that we just have the base-85 | |
1010 | * encoding overhead (25%). Furthermore, Level 3 PostScript printers also | |
1011 | * support Flate compression. | |
1012 | * | |
1013 | * That said, the most efficient path with the highest quality is for Clients | |
1014 | * to supply PDF files and us to use the existing PDF to PostScript conversion | |
1015 | * filters. | |
