Struct PaintRegion 

pub struct PaintRegion {
    pub scale: f64,
    pub width: u32,
    pub height: u32,
    /* private fields */
}

A resolved document region painted into a smaller output surface.

Layout remains the layout of the full document. Only scene coordinates and culling change, so a diagnostic crop answers what the application actually drew at that position without rasterising unrelated window pixels.

Fields

scale: f64

width: u32

height: u32
