Syntax
int SDL_RenderCopy(SDL_TextureID textureID,
const SDL_Rect* srcrect,
const SDL_Rect* dstrect)
Function Parameters
textureID |
the source texture; see Remarks for details |
srcrect |
a pointer to the source rectangle, or NULL for the entire texture |
dstrect |
a pointer to the destination rectangle, or NULL for the entire rendering target |
Return Value
Returns 0 on success, or -1 if there is no rendering context current or the driver doesn't support the requested operation; call SDL_GetError() for more information.

Remarks
The texture is blended with the destination based on its blend mode set with SDL_SetTextureBlendMode().
The texture color is affected based on the color modulation set by SDL_SetTextureColorMod(). The texture alpha is affected based on the alpha modulation set by SDL_SetTextureAlphaMod().
