NAME¶

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

SYNOPSIS¶

#include <SDL3/SDL_render.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);

FUNCTION PARAMETERS¶

renderer

the renderer which should copy parts of a texture.

texture

the source texture.

srcrect

a pointer to the source rectangle, or NULL for the entire texture.

origin

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.

right

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.

down

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.

RETURN VALUE¶

Returns true on success or false on failure; call SDL_GetError() for more information.
