SDL_RenderSetIntegerScale

Set whether to force integer scales for resolution-independent rendering.

Header File

Syntax

int SDL_RenderSetIntegerScale(SDL_Renderer * renderer,
                              SDL_bool enable);

Function Parameters

SDL_Renderer *	renderer	the renderer for which integer scaling should be set.
SDL_bool	enable	enable or disable the integer scaling for rendering.

Return Value

(int) Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Remarks

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.

Version

This function is available since SDL 2.0.5.
