Hi,
I am experimenting with the libgr-progs library on my linux server which is used to resize pnm images online.
The line from php looks like this:
system("pnmscale -xy 400 300 $tmpimg | cjpeg -smoo 0 -qual 80 >$imgfile"
;
I wonder what more parameters I can add to the code except from '-smoo' and '-qual'. I am specifically looking for a sharpen function and perhaps brightness.
Anyone knows where I can find documentation for this library? So far I only found links to the rpm file, o luck for documentation.
Thanks,
Ron
