Examples

ParagraphStyle style = new() { DefaultStyle = new TextStyle { FontFamilies = [family], Size = 16 } };
Paragraph paragraph = Paragraph.Create("A paragraph is shaped once and laid out at any width.", style);

// Each width gives an immutable layout: lines of glyph runs, positioned from the box's top-left corner.
TextLayout narrow = paragraph.Layout(120);
TextLayout wide = paragraph.Layout(400);
foreach (TextLine line in narrow.Lines)
{
    string text = paragraph.Text[line.Start..line.End];   // the line's text, its trailing space included
    float baseline = line.Baseline;                        // y of the baseline
    foreach (LayoutRun run in line.Runs)
    {
        GlyphRun? glyphs = run.Glyphs;                     // glyphs at their layout positions
    }
}

// No wrapping: the box is as wide as the longest line.
TextLayout unbounded = paragraph.Layout(float.PositiveInfinity);
