Struct ScreenDescriptor 

pub struct ScreenDescriptor {
    pub size_in_pixels: [u32; 2],
    pub pixels_per_point: f32,
}

Available on crate feature egui only.

The target a UI frame is drawn into and the density it is drawn at.

The two are needed together and in opposite units, which is the easiest thing to get wrong here: egui tessellates in logical points, so the projection takes the point size, while a scissor rectangle is in physical pixels, so the clip rectangles are scaled by Self::pixels_per_point.

Fields

size_in_pixels: [u32; 2]

The target’s size in physical pixels.

pixels_per_point: f32

How many physical pixels one logical point covers.

Implementations

impl ScreenDescriptor

pub fn size_in_points(self) -> [f32; 2]

The target’s size in logical points, which is what the UI’s projection and its RawInput::screen_rect are expressed in.
