GlyphBitmap

Struct GlyphBitmap 

Source
pub struct GlyphBitmap<'a> {
    pub data: &'a [u8],
    pub x: i32,
    pub y: i32,
    pub w: i32,
    pub h: i32,
    pub aa: bool,
}
Expand description

A rasterized glyph bitmap as produced by a font renderer.

The origin (x, y) is the pen-position offset in device pixels: the top-left of the bitmap maps to (pen_x - x, pen_y - y).

Fields§

§data: &'a [u8]

Raw bitmap data. For AA glyphs: w bytes per row. For mono: ceil(w/8) bytes per row.

§x: i32

Horizontal offset from the pen position to the left edge of the bitmap.

§y: i32

Vertical offset from the pen position to the top edge of the bitmap.

§w: i32

Width in pixels.

§h: i32

Height in pixels.

§aa: bool

true for anti-aliased (one u8 coverage byte per pixel); false for 1-bit MSB-first packed mono.
