Color/Shade Reducing - missing feature? Options

[Guest_Andreas Kieser_*]

It makes a big difference in size in indexed color formats how many colors a picture has. One can see this when switching from 8 to 4 bit (or 2). PMView sometimes reduces the number of colors according to internal tables (it says 6-bit for example).

But: I didn't ever get the hang of willingly reducing the number of colors - say: from 254 or such to say 137 which may preserve an acceptable quality but reduces the needed size to a minimum.

It is doable: one might edit the colors within the palette editor to equal values - PMView will correct the numbers after loading the palette again.

I think that this process could be "automized" and the "quantizing" of colors could be done by algorithms that might well be implemented in the code.

I know that christmas hasn't come yet but .... ;-)))

This is because the color reduction algorithm uses only 6 bits per color (instead of 8).

Usually this is good enough. I have planned to add a full 8-bit reduction, but because noone has requested it (yet), it is not high priority...

Thanks,
