Header File

int SDL_RenderSetIntegerScale(SDL_Renderer * renderer,
                              SDL_bool enable);

Function Parameters

renderer the renderer for which integer scaling should be set

This function restricts the logical viewport to integer values - that is, when a resolution is between two multiples of a logical size, the viewport size is rounded down to the lower multiple.


This function is available since SDL 2.0.5.
