36 | * Modified by Marvin Solomon, Univeristy of Wisconsin, to handle Apple | |||
37 | * Laserwriter (PostScript) devices (-device ps). | |||
38 | * Also accepts the -compact flag that produces more compact output | |||
39 | * by using run-length encoding on white (1) pixels. | |||
40 | * This version does not (yet) support the following options | |||

59 | * | |||
60 | * Modified by Bob Scheifler for 2x2 grayscale, then ... | |||
61 | * Modified by Angela Bock and E. Mike Durbin, Rich Inc., to produce output | |||
62 | * using 2x2, 3x3, or 4x4 grayscales. This version modifies the grayscale | |||
63 | * conversion option of -gray to accept an input of 2, 3, or 4 to signify | |||
64 | * the gray level desired. The output is produced, using 5, 10, or 17-level | |||
65 | * gray scales, respectively. | |||
66 | * | |||
67 | * Modifications by Larry Rupp, Hewlett-Packard Company, to support HP | |||
68 | * LaserJet, PaintJet, and other PCL printers. Added "ljet" and "pjet" | |||
69 | * to devices recognized. Also added -density, -cutoff, and -noposition | |||
70 | * command line options. | |||
