Hi Werner, Here is the 92 enum's currently documented, massaged to fit into freetype's FT_Err_* , as FT_Err_FONTVAL_*
As FreeType only have 95 before that, this doubts your original list to 187. Here is a run through: - 76 of them were documented in FontVal 1.0, 2 AFAIK unused, 4 are emitted by the C# side of things so in reality irrelevant: - - A_ExceptionUnhandled: generic "shit happens". Currently also covers FreeType existing with an error code, but I think I'll split off and create a 93th to distinguish between Freetype errors and non-Freetype errors. - - E_rasterization: when font does not pass preliminary check and does not proceed to be analysed hinting-instructions wise; like missing other tables, etc. -- P_rasterization: this isn't an error but the absence of everything else. -- I_rasterization: CFF font, not going through freetype. - "W_Need_Newer_FreeType" was the 77th added two years ago, as a place-holder for eventually things being merged into freetype and doing version checks. Currently unused. - the 15 *_FT_* ones were added between FontVal 2.0 and 2.1. I know we don't agree on W_FT_VALUE_OUT_OF_RANGE_SLOOP_ZERO . I'll think about it some more; the actual cases affected are in fact small. - I_FT_Error_Supplymentary_Info is a generic "more information" delaying and anticipating a "A_ExceptionUnhandled" . - I'll likely add a 93th to split off generic 'misc shit happens' from 'freetype shit happens'. ==== Although I did put a place holder for freetype version check two years ago, and intended future code to be merged/mergeable at some point, I am increasingly not convinced that it is a good idea for the clutter it would create. I don't think you would like it either - doubling the number of error codes for one application's use. But anyway, this is to standardise the interface, to prevent time being wasted by/on people forking the code in an incompatible way in the future. If you want to re-arrange/re-number them, etc, I am okay with it, as long as the last part e.g. "I_FT_Error_Supplymentary_Info" of the string-form stays the same. (or I'll need to change the c# side to cope). P.S. curiously the incompatible fork uses 72 enums, but at least one from the C# side. So it only has 71 of the correct enums. Sigh.
