sdlRenderCopyEx function
Copy a portion of the texture to the current rendering, with optional rotation and flipping.
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().
\param renderer the rendering context
\param texture the source texture
\param srcrect the source SDL_Rect structure or NULL for the entire texture
\param dstrect the destination SDL_Rect structure or NULL for the entire
rendering target
\param angle an angle in degrees that indicates the rotation that will be
applied to dstrect, rotating it in a clockwise direction
\param 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
)
\param 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.
\since This function is available since SDL 2.0.0.
