SDL_RenderCopyEx

Use this function to 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.

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; see Remarks for details

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.

Code Examples

You can add your code example here

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().
