11 * Some Type 1, Multiple Masters, and CID-keyed PostScript fonts aren't
16 Of course, there might be bugs in FreeType, but some fonts based on
17 the PostScript format can't be handled indeed. The reason is that
18 FreeType doesn't contain a full PostScript interpreter but applies
19 pattern matching instead. In case a font doesn't follow the standard
20 structure of the given font format, FreeType fails. A typical example
21 is Adobe's `Optima' font family which contains extra code to switch
22 between low and high resolution versions of the glyphs.
24 It might be possible to patch FreeType in some situations, though.
25 Please report failing fonts so that we investigate the problem and set
26 up a list of such problematic fonts.
29 * Why do identical FreeType versions render differently on different
34 Different distributions compile FreeType with different options. The
35 developer version of a distribution's FreeType package, which is
36 needed to compile your program against FreeType, includes the file
37 ftoption.h. Compare each platform's copy of ftoption.h to find the

48 * I get an `internal compilation error' (ICE) while compiling FreeType
51 This has been reported for the following compiler version:
53 Intel(R) C++ Compiler for 32-bit applications,
54 Version 9.0 Build 20050430Z Package ID: W_CC_P_9.0.019
58 The best solution is to update the compiler to version
60 Intel(R) C++ Compiler for 32-bit applications,
61 Version 9.1 Build 20060323Z Package ID: W_CC_P_9.1.022
63 or newer. If this isn't feasible, apply the following patch.
