Trait fimg::BlendingOverlay

pub trait BlendingOverlay<W> {
    // Required method
    unsafe fn overlay_blended(&mut self, with: &W) -> &mut Self;
}

This blends the images together, like imageops::overlay.

Required Methods

unsafe fn overlay_blended(&mut self, with: &W) -> &mut Self

Overlay with => self, blending. You probably do not need this, unless your images make much usage of alpha. If you only have 2 alpha states, 0 | 255 (transparent | opaque), please use Overlay, as it is much faster.

Safety

UB if a.width != b.width || a.height != b.height
