Enum ScalingMode

pub enum ScalingMode {
    Fixed {
        width: f32,
        height: f32,
    },
    WindowSize(f32),
    AutoMin {
        min_width: f32,

        max_height: f32,

}

Scaling mode for OrthographicProjection.

Examples

Configure the orthographic projection to two world units per window height:

let projection = Projection::Orthographic(OrthographicProjection {
   scaling_mode: ScalingMode::FixedVertical(2.0),
   ..OrthographicProjection::default()
});

Variants

Fixed

Manually specify the projection’s size, ignoring window resizing. The image will stretch. Arguments are in world units.

Fields

width: f32

height: f32

WindowSize(f32)

Match the viewport size. The argument is the number of pixels that equals one world unit.

AutoMin

Keeping the aspect ratio while the axes can’t be smaller than given minimum. Arguments are in world units.

Fields

min_width: f32

min_height: f32

AutoMax

Keeping the aspect ratio while the axes can’t be bigger than given maximum. Arguments are in world units.

Fields

max_width: f32

max_height: f32

FixedVertical(f32)

Keep the projection’s height constant; width will be adjusted to match aspect ratio. The argument is the desired height of the projection in world units.

FixedHorizontal(f32)

Keep the projection’s width constant; height will be adjusted to match aspect ratio. The argument is the desired width of the projection in world units.
