You should use the drawable classes to draw text on an image:
using (MagickImage image = new MagickImage(Color.Black, 100, 100)) { DrawableFont font = new DrawableFont("PMingLiu"); DrawablePointSize pointSize = new DrawablePointSize(20); DrawableStrokeColor strokeColor = new DrawableStrokeColor(Color.White); DrawableText text = new DrawableText("YOUR TEXT"); image.Draw(font, pointSize, strokeColor, text); }
