NAME
SDL_RenderTextureAffine - Copy a portion of the source texture to the current rendering target, with affine transform, at subpixel precision.
HEADER FILE
Defined in SDL3/SDL_render.h
SYNOPSIS
#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);
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.
