Struct CustomPointerIcon 

pub struct CustomPointerIcon { /* private fields */ }

An application-drawn pointer shape: RGBA pixels plus the hotspot, the pixel inside the image that sits exactly on the pointer’s position.

The alpha channel is not premultiplied, which is what both winit and the browser expect of cursor images.

Implementations

impl CustomPointerIcon

pub fn new( image: ImageBitmap, hotspot_x: u32, hotspot_y: u32, ) -> Result<CustomPointerIcon, PointerIconError>

Builds a custom pointer icon from image, with its hotspot at (hotspot_x, hotspot_y) pixels from the image’s top-left corner.

pub fn image(&self) -> &ImageBitmap

The icon’s pixels, tightly packed RGBA8 with straight (not premultiplied) alpha.

pub fn hotspot_x(&self) -> u32

The hotspot’s x offset from the image’s left edge, in pixels.

pub fn hotspot_y(&self) -> u32

The hotspot’s y offset from the image’s top edge, in pixels.

pub fn id(&self) -> u64

A stable identity derived from the pixels and the hotspot. Platform backends key their per-window cursor caches on it so an icon that reappears across frames is uploaded to the windowing system once.
