| Abstract: | If the Freetype libraries are used in the embedded high-definition movie player, the srt subtitle has a problem of lag. This paper presents a method to realize the TrueType fonts drive, establishes the local indexes for the fonts, and puts all the necessary data of TrueType fonts file into memory to found the glyf memory fonts database. Test shows that the developed drive is stable and reliable and is ideal for the resource-constrained embedded platform. |
