I just happened to notice this...
I've only got AGA so I've been running V on a 256-colour screen. In
an effort to speed up scrolling, I reduced that to 64 colours.
The settings for images in Voyager prefs allow selection of dithering,
colour quantization and DCT accuracy. Some of which are specific to
jpgs. It seems that if "Quantiztion=2-pass " is selected, the other
functions are meaningless. So an undithered 64-colour image is
produced. Selecting Quantization=simple, will permit some sort of
dithering, but at an even worse output quality than before.
So strangely, 256-colour dithered with simple-Q looks awful, whereas
2-pass Q no dither looks ok. Why can't I get 2-pass *and* dithered,
which would look almost perfect in 256-colour?
Am I missing something? Will there be any mods in VNG 3 in the image
handling?
Before anybody says it - I know. Get a gfx card. In fact I've got a
question about that. The BVision is a good option for me because I
like to tempt fate and I could try and cram it into a desktop A1200.
But some people said you could actually overload the motherboard pcb
tracking like this. Is that really true?

Ian
