Struct egui::AlphaImage

source · [−]

pub struct AlphaImage {
    pub size: [usize; 2],
    pub pixels: Vec<u8, Global>,
}

Expand description

An 8-bit image, representing difference levels of transparent white.

Used for the font texture

Fields

size: [usize; 2]

width, height

pixels: Vec<u8, Global>

The alpha (linear space 0-255) of something white.

One byte per pixel. 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.
