.pbm file image render - [vhold] scanline-wiggles?
问题 I'm trying to hack-up a program to read a pbm, pgm, or ppm file and render the image to the postscript output device using the image operator. Just testing the P4 input (binary portable (1-bit) bitmap) path, but my output is all screwy. %! % cf. http://en.wikipedia.org/wiki/Netpbm_format % cf. http://en.wikipedia.org/wiki/Computer_Graphics (origin of image) % $ wget http://upload.wikimedia.org/wikipedia/commons/thumb/2/23/Spacewar%21-PDP-1-20070512.jpg/320px-Spacewar%21-PDP-1-20070512.jpg % $
