Save Palettes as .cl2

[WerhnerHeisenberg]

I would to ask if you can make the program save the pallets as .cl2?. Sorry for posting a request here.

Actually, I do not even know what a .cl2 file looks like. What is that?

[WerhnerHeisenberg]

Inside this 7zip file will found the .tm2 image and the pallet in cl2 format!.

If you just want to apply the palette to the grayscale image, you can use ImageMagick's convert command.

convert gray_image.png palette.png -clut output_colored_image.png

Which 7zip file?

Sorry, the GitHub seems not to uploaded the file. Here: https://mega.nz/#!jpczGIzT!_85J5t3-Q01AKixlusISDuMqeYBFAFTsod-4yl_nq0E

As I said, you can easily apply the palette to the grayscale image via the command line, and using the convert command of ImageMagick:

convert gray_image.png palette.png -clut output_colored_image.png

If you want to keep the transparency of the palette, then you can use the command:

convert -alpha Off image_grayscale.png -channel RGBA palette.png -clut image_colored.png

This is the result with your tm2 file:

If you want to remove the alpha, but you don't want to make fully transparent colors show, after you apply the palette, you can run the command: convert image_colored_with_alpha.png -channel Alpha -evaluate Multiply 2 output.png

you can replace the "2" with whatever amount you want to make the image less transparent. If you use 256, it will make every color, apart from the ones with full transparency, to appear as solid.

As you can see, you do not need any .cI2 file to work with multipalette images.

Thanks!

Did you know if is possible to edit this images with new colors?.

[marco-calautti]

You just have to do the reverse. Modify the colored image, and extract the palette with imagemagick.

You can find a lot of tutorials for that online.

Can you tell me white my images are all resulting in a background black and not like yours?.

[marco-calautti]

You have to keep the transparency of the palette, when applying it to the grayscale image: convert -alpha Off image_grayscale.png -channel RGBA palette.png -clut image_colored.png
