SDL_SetRenderScale3
Set the drawing scale for rendering on the current target.
Usage
#include "SDL3/SDL.h"
bool SDL_SetRenderScale(SDL_Renderer *renderer, float scaleX, float scaleY);
Header file
Defined in SDL3/SDL_render.h
Overview
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.
Each render target has its own scale. This function sets the scale for the current render target.
Function parameters
renderer
|
the rendering context. |
|---|---|
scaleX
|
the horizontal scaling factor. |
scaleY

Return value
Returns true on success or false on failure; call
SDL_GetError () for more information.
Thread safety
This function should only be called on the main thread.
