Suggestions for +additions or other improvements to this file are welcome. + +---------------------------------------------------------------------- + +Running Problems +================ + + +* Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't + handled correctly. + +----- + +Of course, there might be bugs in FreeType, but some fonts based on +the PostScript format can't be handled indeed. The reason is that +FreeType doesn't contain a full PostScript interpreter but applies +pattern matching instead. In case a font doesn't follow the standard +structure of the given font format, FreeType fails. A typical example +is Adobe's `Optima' font family which contains extra code to switch +between low and high resolution versions of the glyphs. + +It might be possible to patch FreeType in some situations, though. +Please report failing fonts so that we investigate the problem and set +up a list of such problematic fonts. + + +* Why do identical FreeType versions render differently on different + platforms? + +----- + +Different distributions compile FreeType with different options. The +developer version of a distribution's FreeType package, which is +needed to compile your program against FreeType, includes the file +ftoption.h. Compare each platform's copy of ftoption.h to find the +differences. + + +---------------------------------------------------------------------- + + +Compilation Problems +==================== + + +* I get an `internal compilation error' (ICE) while compiling FreeType + 2.2.1 with Intel C++. + + This has been reported for the following compiler version: + + Intel(R) C++ Compiler for 32-bit applications, + Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019 + +----- + +The best solution is to update the compiler to version + + Intel(R) C++ Compiler for 32-bit applications, + Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022 + +or newer.
