Werner Almesberger	080978ade0	ubb-vga2: added support for showing a PPM image ... - Makefile (OBJS): added ppm.o and ppmimg.o - ppm.h (load_ppm), ppm.c: PPM file loader, adapted from eda-tools/schhist/ppmdiff/ppmdiff.c - ubb-vga.h (img_name, ppmimg), ppmimg.c: PPM image to frame buffer converter - ubb-vga2.c (usage, main): the threshold is now set with the option -l - ubb-vga2.c (usage, main): if a second argument is given, treat it as a PPM file - ubb-vga2.c (usage): also documented option -t	2011-04-28 00:38:13 -03:00
