SDL_RenderTextureAffine(3) SDL3 FUNCTIONS SDL_RenderTextureAffine(3)

SDL_RenderTextureAffine - Copy a portion of the source texture to the current rendering target, with affine transform, at subpixel precision.

Defined in SDL3/SDL_render.h

#include "SDL3/SDL.h"
bool SDL_RenderTextureAffine(SDL_Renderer *renderer, SDL_Texture *texture,
                         const SDL_FRect *srcrect, const SDL_FPoint *origin,
                         const SDL_FPoint *right, const SDL_FPoint *down);

the renderer which should copy parts of a texture.
the source texture.
a pointer to the source rectangle, or NULL for the entire texture.
a pointer to a point indicating where the top-left corner of srcrect should be mapped to, or NULL for the rendering target's origin.
a pointer to a point indicating where the top-right corner of srcrect should be mapped to, or NULL for the rendering target's top-right corner.
a pointer to a point indicating where the bottom-left corner of srcrect should be mapped to, or NULL for the rendering target's bottom-left corner.

Returns true on success or false on failure; call

SDL_GetError () for more information.

You may only call this function from the main thread.

This function is available since SDL 3.2.0.
