surface.rs

//! SDL surfaces are buffers of pixels in system RAM. These are useful for
//! passing around and manipulating images that are not stored in GPU memory.
//!
//! [`SDL_Surface`] makes serious efforts to manage images in various formats, and
//! provides a reasonable toolbox for transforming the data, including copying
//! between surfaces, filling rectangles in the image data, etc.
//!
//! There is also a simple .bmp loader, [`SDL_LoadBMP()`], and a simple .png
//! loader, [`SDL_LoadPNG()`]. SDL itself does not provide loaders for other file
//! formats, but there are several excellent external libraries that do,
//! including its own satellite library,
//! [SDL_image](https://wiki.libsdl.org/SDL3_image)
//! .
//!
//! In general these functions are thread-safe in that they can be called on
//! different threads with different surfaces. You should not try to modify any
//! surface from two threads simultaneously.

    ///   `srcrect`.
    /// - `scale`: the scale used to transform the corner of `srcrect` into the
    ///   corner of `dstrect`, or 0.0f for an unscaled blit.
    /// - `scaleMode`: scale algorithm to be used.
    /// - `dst`: the [`SDL_Surface`] structure that is the blit target.
