/*
* imagetops.c
*
* This generates a PostScript image, optionally rotating and setting
* a scaling factor for printing with maximum size on 8.5 x 11
* paper at 300 ppi.
*
* Syntax: imagetops <filein> <level> <fileout>
*
* level (corresponding to PostScript compression level):
* 1 for uncompressed
* 2 for compression with g4 for 1 bpp and dct for everything else
* 3 for compression with flate
*
* The output PostScript file can be printed with lpr or lp.
* Examples of the invocation for lp are:
* lp -d <printer> <ps-file>
* lp -d <printer> -o ColorModel=Color <ps-file>
