Microchip Technology Application Note AN1182 - Fonts in the Microchip Graphics Library.

The Microchip graphics library creates font images that contain only the characters that an application will be using. That significantly reduces the amount of system memory required for fonts. This application note describes the format of the Microchip graphics library’s font image. It also tells how to reduce the number of characters in a font and automate the creation of the character arrays referring to an application’s strengths. The examples in this document are applicable to 16 and 32bit PIC microcontrollers with peripherals capable of connecting to display devices such as the parallel master port or PMP which are supported by the Microchip graphics library. To avoid memory related costs and font sized inefficiencies that can be associated with displayed font images. The Microchip graphics library generates font images with reduced character sets. By doing this, all unused characters are eliminated from the font image. This allows simple embedded designs to integrate more functionality into very limited memory systems and easily adapt their application to different languages.
