Struct TextMeasure 

pub struct TextMeasure {
    pub box_width: u32,
    pub box_height: u32,
    pub decoration_margin: u32,
    pub content: [f32; 4],
    pub ink: Option<[f32; 4]>,
    pub line_count: u32,
    pub first_baseline: f32,
    pub last_baseline: f32,
}

Text geometry from TextRasterizer::measure. Rectangles are [left, top, right, bottom] in pixels from the layout box’s top-left, which sits at (TextTexture::layout_x, TextTexture::layout_y) in the rasterized texture.

Fields

box_width: u32

The wrap width, else the widest line, rounded up.

box_height: u32

All lines’ em boxes, rounded up.

decoration_margin: u32

TextRasterRequest::decoration_margin.

content: [f32; 4]

Horizontal extent of the line advances by the box height, grown by the decoration margin. Unlike ink, it does not depend on glyph shapes.

ink: Option<[f32; 4]>

Bounds of everything drawn (glyphs, strokes, background), at most a pixel loose (more for COLR clip boxes). None when nothing is drawn.

line_count: u32

Number of laid-out lines.

first_baseline: f32

First alphabetic baseline, in pixels from the layout box’s top.

last_baseline: f32

Last alphabetic baseline, in pixels from the layout box’s top.
