Enum TextPathSide

Namespace

Egami.Drawing

Assembly

Egami.Drawing.dll

Which side of a path text stands on.

public enum TextPathSide

Fields

Left = 0

The text runs along the path's direction, standing on its left (above a left-to-right line on a y-down canvas).

Right = 1

The text runs against the path's direction, standing on its right: the path walked backwards, as SVG's side="right".

Examples

// A label along a curve: each glyph's midpoint on the path, turned to its direction, as SVG's textPath. The result is
// still a glyph run, so a PDF backend writes it as searchable text.
Path curve = new PathBuilder().MoveTo(20, 150).CubicTo(80, 20, 240, 20, 300, 150).ToPath();
var font = new Font(face, 18);
using (RasterCanvas<Rgba8> canvas = image.CreateCanvas())
{
    canvas.DrawTextOnPath("Text that follows the curve", curve, font, Rgba8.Black,
        new TextOnPathOptions { StartFraction = 0.5f, Anchor = TextAnchor.Center, BaselineShift = 4 });
}

// Or place glyphs yourself, each with its own turn and scale.
GlyphRun dial = GlyphRun.CreateTransformed(font, [face.GetGlyph('N'), face.GetGlyph('E')],
    [GlyphTransform.FromRotationScale(1, 0, new Vector2(150, 30)), GlyphTransform.FromRotationScale(1, 90, new Vector2(290, 90))]);
