Available on crate feature mirror only.

What the mirror window streams.

Variants

Toplevel(String)

Mirror the toplevel with this ext-foreign-toplevel identifier.

Region

Mirror (and magnify) a fixed logical region. We capture the covering output live and show only the region’s sub-rectangle of it; mono-output for now.

Fields

output: String

Name of the output to capture (the one covering the region’s top-left).

crop: [f32; 4]

Normalized sub-rectangle (min_x, min_y, max_x, max_y) of the region within that output’s frame (scale-independent, so it survives any physical resolution the frames arrive at).

region_w: u32

Logical region width; fixes the window aspect ratio.

region_h: u32

Logical region height; fixes the window aspect ratio.

zoom: f32

Magnification factor (initial window size = region × zoom).

ToplevelRegion

Mirror (and magnify) a sub-rectangle of a window. Captures the toplevel (so it follows the window across moves/workspaces) and shows only crop of it.

Fields

id: String

ext-foreign-toplevel identifier of the window to capture.

crop: [f32; 4]

Normalized sub-rectangle of the region within the window’s content.

region_w: u32

Logical region width; fixes the window aspect ratio.

region_h: u32

Logical region height; fixes the window aspect ratio.

zoom: f32

Magnification factor (initial window size = region × zoom).
