}
Expand description

“Monitor” configuration used by windows in headless mode.

Fields§

§scale_factor: Option<Factor>

The scale factor used for the headless layout and rendering.

If set to None, falls back to the parent scale-factor, or 1.0 if the headless window has not parent.

None by default.

§size: Size2D<Dip, Dip>

Size of the imaginary monitor screen that contains the headless window.

This is used to calculate relative lengths in the window size definition and is defined in layout pixels instead of device like in a real monitor info.

(11608, 8708) by default.

§ppi: Ppi

Pixel-per-inches used for the headless layout and rendering.
