Enum font_kit::canvas::RasterizationOptions

source · [−]

pub enum RasterizationOptions {
    Bilevel,
    GrayscaleAa,
    SubpixelAa,
}

Expand description

The antialiasing strategy that should be used when rasterizing glyphs.

Variants

`Bilevel`

“Black-and-white” rendering. Each pixel is either entirely on or off.

`GrayscaleAa`

Grayscale antialiasing. Only one channel is used.

`SubpixelAa`

Subpixel RGB antialiasing, for LCD screens.
