- Thank you for the reply, I found the solution in scale'ing my
- jpeg's with programs explained to me by Chad Randall (thanks
- a million). He said to use the Netpbm archives on Aminet.
-
- After obtaining some of these programs all I had to use was the
- jpeg specific utilities in the ppm2AGA16.lha archive.
-
- A simple command via the CLI allowed me to direct the utility
- to get the jpeg off my harddrive scale it to any size I requested
- and then save it off again to my harddrive. It uses very little
- memory and was a complete success in dealing with these huge jpeg
- images.
-
- ex: djpeg -scale 1/2 -gif Work:filename.jpeg Work:filename_scale.gif
- Load into ADpro as a .gif, modify and resave out as a jpeg.
-
- Again thanks to all who replied.
