Copy a portion of the texture to the current rendering, with optional rotation and flipping.
int SDL_RenderCopyEx(SDL_Renderer * renderer,
SDL_Texture * texture,
const SDL_Rect * srcrect,
const SDL_Rect * dstrect,
const double angle,
const SDL_Point *center,
const SDL_RendererFlip flip);| renderer | the rendering context |
| texture | the source texture |
| srcrect | the source SDL_Rect structure or NULL for the entire texture |
| dstrect | the destination SDL_Rect structure or NULL for the entire rendering target |
| angle | an angle in degrees that indicates the rotation that will be applied to dstrect, rotating it in a clockwise direction |
| center | a pointer to a point indicating the point around which dstrect will be rotated (if NULL, rotation will be done around dstrect.w / 2, dstrect.h / 2) |
| flip | a SDL_RendererFlip value stating which flipping actions should be performed on the texture |
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Copy a portion of the texture to the current rendering target, optionally rotating it by angle around the given center and also flipping it top-bottom and/or left-right.
The texture is blended with the destination based on its blend mode set with SDL_SetTextureBlendMode().
The texture color is affected based on its color modulation set by SDL_SetTextureColorMod().
The texture alpha is affected based on its alpha modulation set by SDL_SetTextureAlphaMod().
This function is available since SDL 2.0.0.
