Struct egui::FontImage

source · [−]

pub struct FontImage {
    pub size: [usize; 2],
    pub pixels: Vec<f32, Global>,
}

Expand description

A single-channel image designed for the font texture.

Each value represents “coverage”, i.e. how much a texel is covered by a character.

This is roughly interpreted as the opacity of a white image.

Fields

size: [usize; 2]

width, height

pixels: Vec<f32, Global>

The coverage value.

Often you want to use Self::srgba_pixels instead.

Implementations

source

pub fn srgba_pixels(&self, gamma: f32) -> impl ExactSizeIterator

Returns the textures as sRGBA premultiplied pixels, row by row, top to bottom.

gamma should normally be set to 1.0. If you are having problems with text looking skinny and pixelated, try setting a lower gamma, e.g. 0.5.

source

pub fn region(&self, [usize ; 2], [usize ; 2]) -> FontImage

Clone a sub-region as a new image.
