Syntax
SDL_Texture* SDL_CreateTexture(SDL_Renderer* renderer,
Uint32 format,
int access,
int w,
int h)
Function Parameters
renderer |
the rendering context |
format |
one of the enumerated values in SDL_PixelFormatEnum; see Remarks for details |
access |
one of the enumerated values in SDL_TextureAccess; see Remarks for details |
w |
the width of the texture in pixels |
h |
the height of the texture in pixels |
Return Value
Returns a pointer to the created texture or NULL if no rendering context was active, the format was unsupported, or the width or height were out of range; call SDL_GetError() for more information.
