DS development > Weird color issues...

#137617 - calcprogrammer1 - Tue Aug 14, 2007 1:08 am

I was working on my program, and when I added a 16 color background on BG 2, my back gif image corrupted.

It ran fine with BG3 being the 16bit image and bg1 being the keyboard (no bg 1 on top screen, BG 2 for text, and sprites). Then when I went to use normal text, it gave me some random error, so I decided to change 16bit to 8 bit backgrounds. The picture shows up as having an 8 bit depth in Windows, but when I use it, I get some random issues. Gimp says there is no RED in the palette, (how do you use palettes in Gimp anyways, or another free program).

EDIT:

Weird, If I remove the init 16 color BG 2 on the bottom screen (using it for 16cText), then it doesn't affect, but the top screen is still messed up (it's using BG2 for 16cText as well, still enabled).

In GIMP 2, palettes show up in the Colormap window: File > Dialogs > Colormap.

If an image has 1-bit transparency, the palette entry assigned to the transparent color might show up as the background color. What is the value of BG_PALETTE[0] (or whatever PALib calls it)?

I opened the Color map in Gimp (I have GIMP 2), and also I have Desmume open showing the problem.

Top screen has the problem, it uses BG3 for image, BG2 for 16c text, it worked fine as 16bit though (with text).

Bottom screen doesn't have the problem, it's 8 bit BG3 for the picture, no BG2, and BG1 is keyboard.

EDIT:

When I turn of BG3 (the image) on bottom screen, 16c text works, as does sprites and the keyboard:

Nevermind...the PA_LoadGif function must have loads of bugs or something, PAlib doesn't seem very stable, lots of bugs that shouldn't even be there in the first place.

But anyways, the PA_LoadEasyBG() function helped, though I had to convert my background rather than use GIF.
