SDL_RenderCopy

Copy a portion of the texture to the current rendering target.

Syntax

int SDL_RenderCopy(SDL_Renderer * renderer,
                   SDL_Texture * texture,
                   const SDL_Rect * srcrect,
                   const SDL_Rect * dstrect);

Function Parameters

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; the texture will be stretched to fill the given rectangle

Return Value

Returns 0 on success or a negative error code on failure; 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 its color modulation set by SDL_SetTextureColorMod().

The texture alpha is affected based on its alpha modulation set by SDL_SetTextureAlphaMod().

Version

This function is available since SDL 2.0.0.
