Struct OverlayPart 

pub struct OverlayPart {
    pub pos: [f32; 2],
    pub size: Option<[f32; 2]>,
    pub src: Option<[f32; 4]>,
    pub colour: [f32; 4],
}

One placement of an overlay’s mask.

Fields

pos: [f32; 2]

Top left in output pixels.

size: Option<[f32; 2]>

Size in output pixels; None draws the (cropped) mask at 1:1.

src: Option<[f32; 4]>

The part of the mask drawn, [x0, y0, x1, y1] in mask pixels; None is all of it.

colour: [f32; 4]

[r, g, b, a], sRGB, not premultiplied; multiplied by the mask and the fade.

impl OverlayPart

pub fn rects(&self, mask: &Mask) -> ([f32; 4], [f32; 4])

The mask crop and the output rectangle it lands on, both [x0, y0, x1, y1].
