I issued "I = loadimage ("/usr/share/hplip/data/images/hp-tux-printer.ppm");" w/ the attached file but octave gave me the ff:
"error: load: /usr/share/hplip/data/images/hp-tux-printer.ppm
: inconsistent number of columns near line 2 error: load: unable to extract matrix size from file `/usr/share/hplip/data/images/hp-tux-printer.ppm' error: evaluating assignment _expression_ near line 47, column 8
error: called from `loadimage' in file `/usr/local/share/octave/3.0.0/m/image/loadimage.m' error: evaluating assignment _expression_ near line 1, column 3"
How should I open ppm or ps files? Please help. Thanks!
