- 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.
 - An RGBA file is a color bitmap image format created by Silicon Graphics (SGI). It is similar to the .RGB file as it supports color RGB channels with an alpha channel.
