SDL_RenderCopyEx

Copy a portion of the texture to the current rendering, with optional rotation and flipping.

Syntax

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);

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

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

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Remarks

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().
