Batch Resizing Palettes

Good morning. Before anything, thanks for creating Cyotek Color Palette Editor. It's the best tool I have used for manipulating palettes. But I have a little problem:

I have downloaded a lot of JASC-PAL palettes, to use with Paint Shop Pro. Those palettes are for reducing the image color count, giving a "vintage" or "retro" look.

The problem is that Paint Shop Pro only recognizes the palettes that has 16 colors only. The other palettes (24, 32, 64, 128 colors) are not recognized by Paint Sho Pro.

I have read that JASC-PAL palette standard only supports 16 or 256 colors. Maybe for this reason Paint Shop Pro doesn't load the other palettes.

My question is: Can Cyotek Color Palette Editor "resize" the palette from 24/32/64/128 colors to 256 colors, but in BATCH mode? I have more than 150 palettes to resize.

I have been reading about changing the .pal files manually (they are text files after all), but I don't know hot to do it yet using a batch file.

Thank you very much for your help, and congratulations again for such a great tool.

Hello,

Welcome to the forums and I'm glad you're finding the palette editor useful. Unfortunately at present batch conversion of palettes just does a direct transform from one format to the other, taking into account color space limitations of the conversion format, but not other limits. However, I think your suggestion that the editor should do this is a good one, and I've logged it for inclusion in a future update - the issue number is #300.

I'm currently expanding the editor to support additional formats; but I will aim to have this in version 1.7 as it shouldn't be too much trouble to implement.

Hello,

I just realised I mis-interpreted the question as I was thinking you were converting palettes, not trying to adjust existing ones.

Unfortunately batch operations other than palette conversion are currently not supported, and I hadn't really planned on adding support them either as I didn't think they would see a lot of use.

I will still adjust the batch conversion process, so at least you can "convert" them from JASC to JASC and ensure the palette size is accurate but that's probably as far as I'll go at present.

Edit: PS, if you could let me know where you downloaded the palettes from I could use them to test with.

Hello Richard, thanks for answering. The JASC palettes were downloaded from here: https://lospec.com/palette-list.

As you will see, those are non-standard JASC palettes, because they are not exactly 16-color or 256-color palettes, and Paint Shop Pro does not recognize them.

Hello,

Thanks for the link, looks like some interesting resources there! I'll grab a few of them and use them to test - will let you know when a new build is available.

Hello,

A new nightly build is available that has a few new options for padding palettes when converting them. I've opened the padded palettes in Paint Shop Pro 9 successfully.
