SDL_RenderSetScale

Set the drawing scale for rendering on the current target.

Syntax

int SDL_RenderSetScale(SDL_Renderer * renderer,
                       float scaleX, float scaleY);

Function Parameters

renderer a rendering context
scaleX the horizontal scaling factor
scaleY the vertical scaling factor

Return Value

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

Remarks

The drawing coordinates are scaled by the x/y scaling factors before they are used by the renderer. This allows resolution independent drawing with a single coordinate system.

If this results in scaling or subpixel drawing by the rendering backend, it will be handled using the appropriate quality hints. For best results use integer scaling factors.

Version

This function is available since SDL 2.0.0.
