FreeType can't normally 'emit warning messages' because it is a library, not an app - it's up to the caller how to deal with errors. A new, well documented, error code that the caller can choose to ignore is the way to go, in my opinion.

This is a fundamental question. My opinion is that shifting of glyph elements using TrueType instructions clearly is (a kind of) hinting. In other words, I don't like to change the current behaviour of FreeType without good reasons. However, it might be helpful if FreeType emits a warning message that the font is probably unusable. Hmm. Opinions, please. Maybe most of you disagree, so please chime in. > And detecting of tricky font should be outside of this defines: > > #if defined( TT_CONFIG_OPTION_UNPATENTED_HINTING ) && \ > !defined( TT_CONFIG_OPTION_BYTECODE_INTERPRETER ) > > otherwise, the fonts are not detected on my debian box. This is probably fixed already in the CVS: 2008-11-05 Werner Lemberg <[EMAIL PROTECTED]> * devel/ftoption.h, include/freetype/config/ftoption.h [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Undefine TT_CONFIG_OPTION_UNPATENTED_HINTING. This fixes the return value of `FT_Get_TrueType_Engine_Type' (and makes it work as documented). Reported in bug #441638 of bugzilla.novell.com. Please test. Otherwise, please report the vales of those two macros on your box.
