Cursor

Struct Cursor 

Source
pub struct Cursor { /* private fields */ }
Expand description

The loaded XCursor theme, held for the whole capture so cursor lookups stay cheap.

The default cursor’s frames are parsed once and kept here because they are consulted on nearly every frame; the theme handle is retained alongside them so the rarer named cursors (hand1, text, …) can still be resolved on demand. Everything is sized to the one resolved pixel size.

Implementations§

Source§

impl Cursor

Source

pub fn load(size_override: i32) -> Cursor

Load the theme named by XCURSOR_THEME (default "default") at the requested size.

size_override comes from CaptureSettings.cursor_size (selkies --cursor-size / XCURSOR_SIZE); a value <= 0 falls back to 24. When the theme’s default icon cannot be loaded, a 16×16 solid-red placeholder stands in so the caller always has a valid image.

Source

pub fn get_image(&self, scale: u32, time: Duration) -> Image

The default cursor’s animation frame for time, at the theme size times scale.

Source

pub fn get_image_by_name( &self, name: &str, scale: u32, time: Duration, ) -> Option<Image>

A named cursor’s animation frame for time, or None when the theme lacks it.

Source

pub fn get_sprite(&self, name: &str) -> Option<(RgbaImage, u32, u32)>

A named cursor icon as a premultiplied RGBA image plus its hotspot (x, y), ready for cap_and_encode to size and convert to the straight alpha web clients want. Xcursor stores premultiplied colour, which is also what the compositing paths (get_image*) need for blending, so it is carried through unconverted.
