I was not sure about that before so used +unsigned characters to be safe. The "get character" function still checks +input characters, and panics if an 8-bit character is seen. + +Fixed bug in _RTFToken() where, if a control word was delimited by a space, +the space was left at the end of rtfTextBuf. + +Color values in color table entries are -1 if the values were not specified +for the entry. That means the default color should be used. In earlier +versions, color 0 was assumed to be the default, but since any entry can +be left unspecified, including the entry for color 0, the default color +is left to the writer to decide. + +Instead of ignoring \r and \<10>, and treating \n like \par, \r and \n +are ignored, and \<10> and \<13> are treated like \par. + +The font table destination reader now recognizes old style font tables, +where entries in the table are not surrounded by braces. + +Fixed the stylesheet reader to recognize \sbasedon and \snext explicitly +and use them to set the corresponding fields of RTFStyle structs accordingly, +which it didn't do previously. Worse, none of the elements of the style were +attached except the last. This means that style expansion was completely +broken in 1.04. (Real brain-o-matic programming. Duh. Blush.) + +It also turns out that automatic style expansion (i.e., with no writer +intervention required) is the wrong thing to do (due to the circumstances +under which tabstops are overridden), so it's now up to the writer to +call RTFExpandStyle() explicitly. There is little loss in this since +style expansion was broken anyway. + +RTFGetFont(), RTFGetColor() and RTFGetStyle() didn't work unless you +passed an argument of -1 or 0. Fixed. + +RTFInit() can be called multiple times for translators that wish to +translate multiple files. Formerly the internal state that was built +up would not have been disposed of. + +The reader now recognizes roughly 300 control symbols, or about twice as +many as before. Some of the #define'd constant names have changed: + +rtfBrace -> rtfGroup +rtfLBrace -> rtfBeginGroup +rtfRBrace -> rtfEndGroup + +[rtfDestination, rtfRtf] -> [rtfVersion, -1] + Version number is parameter + +[rtfMacintosh, -1] -> [rtfCharSet, rtfMacChar] + +rtfFontStyle -> rtfFontFamily + Minor number symbols have different names, also. + rtfFType field of RTFColor structure changed correspondingly. + +rtfColorNum -> rtfForeColor + +rtfCurFNotePage ->rtfCurFNote + +rtfEndNotes -> rtfFNoteEndSect + +rtfLineRestart1 -> rtfLineRestart + This was a typo + +rtfAutoPageX -> rtfPageNumLeft +rtfAutoPageY -> rtfPageNumTop + +rtfColumnWid -> rtfColumnSpace + +rtfComment -> rtfIComment + +rtfNewline was deleted +rtfPageContinuous was deleted (use rtfPageCont) + +rtfCurPict (for \chpict) may be bogus. I'm not sure if \chpict is +a legitimate control symbol or not. + + +The functional interface also has many name changes and additions. + +RTFReadHook() -> RTFSetReadHook() +Added RTFGetReadHook(). + +RTFClassCallback() -> RTFSetClassCallback() +Added RTFGetClassCallback(). + +RTFDestinationCallback() -> RTFSetDestinationCallback() +Added RTFGetDestinationCallback(). + +Added RTFSkipGroup(). +Added RTFExpandStyle(). +Added RTFCheckCM(), RTFCheckCMM(), RTFCheckMM(). +Added RTFFree(). + +Deleted RTFStyleExpansion(). + +----------------------------- +rtf2null: + +rtf2null echoes unknown symbols so that it can be used as a quick way of +finding symbols that the reader doesn't recognize. + +----------------------------- +rtf2text: + +More characters in >= 128 range handled. Can switch between character +sets, although only Macintosh character set is handled. + +----------------------------- +rtf2troff: + +Some fprintf's in FlushParState() had no stream argument, causing core dumps. +Fixed. + +Underlining works better now (doesn't destroy multiple-character characters +like \(de, writes smaller output). + +Stikeout works. + +A bit of top/bottom margin support and header/footer support added. + +More characters in >= 128 range handled. Can switch between character +sets, although only Macintosh character set is handled. + +However, the whole thing is more complicated and probably has many new +bugs. |
