This is a standard TrueType font format developed by Apple Computer in 1989. The advantage of TTF till now has been its high level of font display control right up to the pixel. It has a vector format so it’s easy to scale. Today TrueType is used in operating systems from Apple to Microsoft.
This format is used to display bitmap images in the SunOS operating system. It uses the RLE compression algorithm and supports between 1 and 32 bits per pixel. It can be created in the Unix environment, and it is used for certain types of research projects. It is primarily used on Sun Microsystems computers.
