Hi,

I'm trying to display some largish images on my KS3.1 A4000 (2MB CHIP and 16MB Fast RAM), but Visage just gives an error: Not enough memory" (or similar when it tries to load the photo).

The pics (JPGs) are about 2048 x 1536 x 24bit...

Does anyone know of any pic viewers that can somehow get around the 2MB Chip RAM limit?

Cheers,

Mike.



Here is a small program which I wrote quickly. It will display JPEGs of any size on a hires interlaced HAM8 screen using jpeg.library. Pictures are scaled down if needed and converted to HAM on the fly. HAM quality is rather poor and the program is probably quite slow. My CSPPC 060 needs about ten seconds to load one image. On WinUAE it needs less than two seconds.

The program reads the entire directory and you can scroll back and forward using the cursor keys or space / backspace. Esc key quits the program.

Bye,
Thomas
