The documentation of the -width -and -height options in the pnmtops man page in the netpbm-progs package claims, "The page size has no effect, however, when you specify the -imagewidth, -imageheight, or -equalpixels options." I've determined empirically that this simply isn't true. If I give pnmtops a 600dpi PBM which is 8" by 13" and specify "-dpi 600 -equalpixels -noturn -rle", it cuts the bitmap off at 11" in height. If, however, I run the same command with "-height 14", it prints the whole thing (I'm using legal paper, obviously). The program's behavior is probably correct; it's just that the man page needs to be fixed.
OK, fixed manpage. Will be in netpbm-10.19-3 and later. Read ya, Phil
