Re: SOLVED - using sparse-color: special output image format

Hi all, thanks for all your help. You gave me the clues I needed. I tried all of it; the type -a, file, etc etc etc After a clean reboot, it worked fine.

Congradulation to the dev team. I just downloaded the source tar ball. unziped it in a directory of my choosing. Ran ./configure, then ./make, and then sudo make install, and it worked. almost forgot; sudo ldconfig /usr/local/lib to get everything visible and it worked the first time. There is not n...
