strokeWeight

Controls the bias towards thinner or thicker strokes. This bias determines how thin or thick text and lines appear. The valid range is from 0 to 1, where 0 implies a bias towards thinner strokes and 1 implies a bias towards thicker strokes. Thinner strokes look better in poorly lit images, images with heavy shadows, and, more generally, where text is blurry. Thicker strokes look better in well-lit images and, more generally, images with sharp text. The parameter has effect only when outputMode is set to ANTIALIASED.

Default is 0.5.
