Allocate a new RGB surface with with a specific pixel format and existing pixel data.
Defined in SDL_surface.h
SDL_Surface* SDL_CreateRGBSurfaceWithFormatFrom
(void *pixels, int width, int height, int depth, int pitch, Uint32 format);
pixels | a pointer to existing pixel data |
width | the width of the surface |
height | the height of the surface |
depth | the depth of the surface in bits |
pitch | the pitch of the surface in bytes |
format | the SDL_PixelFormatEnum for the new surface's pixel format. |
Returns the new SDL_Surface structure that is created or NULL if it fails; call SDL_GetError() for more information.
This function operates mostly like SDL_CreateRGBSurfaceFrom(), except instead of providing pixel color masks, you provide it with a predefined format from SDL_PixelFormatEnum.
No copy is made of the pixel data. Pixel data is not managed automatically; you must free the surface before you free the pixel data.
This function is available since SDL 2.0.5.
