Defaults to 'path'.The effect depends on the canvas type: Standard (image) glyph and path both result in rasterized text. Glyph mode is faster than path, but may result in lower-quality text, especially when rotated or translated.. PDF glyph will embed text instead of paths into the PDF. This is faster to encode, faster to open with PDF viewers, yields a smaller file size and makes the text. See also: Node.js video manipulation. Deliver and transform images.
