Struct ViewportPixels 

pub struct ViewportPixels {
    pub width: u32,
    pub height: u32,
}

The size of the area a picture is being shown in, in physical pixels — the buffer’s unit, not the widget tree’s.

Named rather than a bare (u32, u32) because this is the one place logical and physical coordinates meet, and mixing them is the failure CLAUDE.md records twice: a 1.6-scale output makes a logical window 1.6x smaller than the buffer it draws into, so a budget computed from logical pixels would decode a picture visibly soft on exactly the displays where it matters most.

Fields

width: u32

height: u32

Implementations

impl ViewportPixels

pub fn from_logical(width: f32, height: f32, scale: f32) -> ViewportPixels

From a logical size and the output’s scale factor. The conversion is here, once, so no caller has to remember which way it goes.
