making a surface = to part of larger surface
Author
is there any good way to "cut" a big surface up by making surfaces = to smaller parts of it
thanks [smile]
Write your own function? It should just be as simple as creating x*y new surfaces and then blitting from the larger ones to the smaller one.
[source lang = "cpp"]//Setup SDL and other stuff. . .SDL_Surface * BigSurface = SDL_LoadBMP("BIGIMAGE.bmp");SDL_Rect SmallImage;SmallImage.x = 0;SmallImage.y = 0;SmallImage.w = 100;SmallImage.h = 100;SDL_Surface * SmallerImage = SDL_CreateRGBSurface(0, SmallImage.w, SmallImage.h, 32, 0 0 0 0); // More info look in the docsSDL_BlitSurface(BigSurface, &SmallImage, SmallerImage, NULL);

you can save an SDL Surface to a file using SDL_SaveBMP().
