SDL3 FUNCTIONS

SDL_SetSurfaceClipRect(3)

SDL_SetSurfaceClipRect - Set the clipping rectangle for a surface.

Defined in SDL3/SDL_surface.h

#include "SDL3/SDL.h"

bool SDL_SetSurfaceClipRect(SDL_Surface *surface, const SDL_Rect *rect);

When surface is the destination of a blit, only the area within the clip rectangle is drawn into.

Note that blits are automatically clipped to the edges of the source and destination surfaces.

surface: the SDL_Surface
structure to be clipped.
rect: the SDL_Rect
structure representing the clipping rectangle, or NULL to disable clipping.

Returns true if the rectangle intersects the surface, otherwise false and blits will be completely clipped.

This function is not thread safe.

This function is available since SDL 3.2.0.
