Enum CoordinateSystem

Help

pub enum CoordinateSystem {
    PositiveYUp,
    PositiveYDown,
}

Available on crate feature dep_fontdue only.

Expand description

The direction that the Y coordinate increases in. Layout needs to be aware of your coordinate system to place the glyphs correctly.

Variants§

§

PositiveYUp

The Y coordinate increases up relative to the window or image. The higher up on the window, the more positive Y becomes.

§

PositiveYDown

The Y coordinate increases down relative to the window or image. The lower down on the window, the more positive Y becomes.
