Struct Image

Help

pub struct Image<H = Handle> {
    pub handle: H,
    pub filter_method: FilterMethod,
    pub rotation: Radians,
    pub opacity: f32,
    pub snap: bool,
}

Expand description

A raster image that can be drawn.

Fields§

§handle: H

The handle of the image.

§filter_method: FilterMethod

The filter method of the image.

§rotation: Radians

The rotation to be applied to the image; on its center.

§opacity: f32

The opacity of the image.

0 means transparent. 1 means opaque.

§snap: bool

If set to true, the image will be snapped to the pixel grid.

This can avoid graphical glitches, specially when using FilterMethod::Nearest.
