Problems with Blitting

SDL Development
1

Hello everbody,

I’ve got a problem with SDL_BlitSurfaces. I got the error “Blit combination
not supported”. What does this mean? I try to blit a surface, which was
created by SDL_CreateRGBSurface(…) and SDL_ttf, on a surface which was
created with SDL_SetVideoMode(…).

Thanks for your help

Do you use the same pixel format between all the surfaces ?

You should try to solve this, applying SDL_DisplayFormat() (SDL_DisplayFormatAlpha()) to the surface before blitting.

unfortunately that should be using the same functionality as his original blit…
the only thing that change is the new surface it makes, which is the same format as the screen.
as far as I know, this should solve nothing.
I’m more interested in what that error means, since I’ve never seen it.
perhaps a quick browse of the relevant source code will reveal all…–
