Struct egui::widgets::ImageSize

source ·
pub struct ImageSize {
    pub maintain_aspect_ratio: bool,
    pub max_size: Vec2,
    pub fit: ImageFit,
}
Expand description

This type determines the constraints on how the size of an image should be calculated.

Fields§

§maintain_aspect_ratio: bool

Whether or not the final size should maintain the original aspect ratio.

This setting is applied last.

This defaults to true.

§max_size: Vec2

Determines the maximum size of the image.

Defaults to Vec2::INFINITY (no limit).

§fit: ImageFit

Determines how the image should shrink/expand/stretch/etc. to fit within its allocated space.

This setting is applied first.

Defaults to ImageFit::Fraction([1, 1])
