- Description
 - PostScript Type 3 consists of glyphs defined using the full PostScript language, rather than just a subset. Because of this, a Type 3 font can do some things that Type 1 fonts cannot do, such as specify shading, color, and fill patterns.
 - 1-bit black and white image; formatted in text format; basic raster image format in which each pixel is represented by a byte that contains a 1 or 0; 1 represents black and 0 represents white pixels.
