[−][src]Function fermium::renderer::SDL_UpdateTexture

pub unsafe extern "C" fn SDL_UpdateTexture(
    texture: *mut SDL_Texture, 
    rect: *const SDL_Rect, 
    pixels: *const c_void, 
    pitch: c_int
) -> c_int

Update the given texture rectangle with new pixel data.

  • texture The texture to update
  • rect A pointer to the rectangle of pixels to update, or NULL to update the entire texture.
  • pixels The raw pixel data in the format of the texture.
  • pitch The number of bytes in a row of pixel data, including padding between lines.

The pixel data must be in the format of the texture. The pixel format can be queried with SDL_QueryTexture.

Returns: 0 on success, or -1 if the texture is not valid.

This is a fairly slow function.
