Function blend

pub fn blend(
    mode: impl Into<RCHandle<SkBlender>>,
    background: impl Into<Option<RCHandle<SkImageFilter>>>,
    foreground: impl Into<Option<RCHandle<SkImageFilter>>>,
    crop_rect: impl Into<CropRect>,
) -> Option<RCHandle<SkImageFilter>>

This filter takes an crate::BlendMode and uses it to composite the two filters together.

• blender - The blender that defines the compositing operation
• background - The Dst pixels used in blending, if null the source bitmap is used.
• foreground - The Src pixels used in blending, if null the source bitmap is used.
• `crop_rect`` Optional rectangle to crop input and output.
