Re-indexation to images (GIMP) - Tobruk - 03-10-2012
Hello!
Recently I edited lots of .bmp's and I re-indexated (I mean: image >> mode >> from RGB to indexed >> the proposed pallet) those images in GIMP, because I want become them thinner (less occupied memory).
Than I launch the game and LF don't changing BLACK to ALPHA CANNAL.
Why?

SORRY FOR WRONG SECTION. I WAS STARED.

The RGB formation of the black color should be (0, 0, 0) or U can say 'pure' black. If the black color formation is for example (0, 0, 1), it will not be recognized as the color key.

But why? RGB image was fine, and re-indexed not fine?

Usually black gets changed to something else than #000000. While you're indexing check the palette of colors carefully to avoid this. Be sure, that black color won't be changed.

alternatively you can also index it, turn it rgb again, make the almost black real black and index it again.
RE: Re-indexation to images (GIMP) - Gad - 03-11-2012
That doesn't make sense. If you index it the real black will get changed.
RE: Re-indexation to images (GIMP) - Bamboori - 03-11-2012
well actually not. you replace all the almost black color with black, so there is no reason for the graphics program to convert it back to a color that doesnt exist in the image.
try it if you dont believe me
edit: @Gad below: weird... it works fine for me in photofilter :/

Somehow doesn't work for me.

An even simpler way than what bamboori suggests would be to show the "Colormap"-dialog (Windows>Dockable dialogs>Colormap), and simply change the color of the black to "000000" (it's the field saying "HTML notation").
