SDL_UpperBlitScaled
Use this function to perform rectangle validation and clipping before passing it to SDL_LowerBlitScaled().
Contents
Syntax
int SDL_UpperBlitScaled(SDL_Surface* src,
const SDL_Rect* srcrect,
SDL_Surface* dst,
SDL_Rect* dstrect)
Function Parameters
src |
the SDL_Surface structure to be copied from |
srcrect |
the SDL_Rect structure representing the rectangle to be copied |
dst |
the SDL_Surface structure that is the blit target |
dstrect |
the SDL_Rect structure representing the rectangle that is copied into |
Return Value
Returns 0 on success, or a negative error code on failure; call SDL_GetError() for more information.
Code Examples

Remarks
This is the public scaled blit function. This function calls SDL_LowerBlitScaled() to complete the blit.
