This is planned in three steps: 1) wxPdfDC with support for Adobe Reader standard fonts 2) as 1) + support for TrueType fonts 3) as 2) + support for OpenType fonts Regards, Ulrich --------------------------------------------------------------------- To unsubscribe, e-mail: wx-users-unsubscribe(a)lists.wxwidgets.org For additional commands, e-mail: wx-users-help(a)lists.wxwidgets.org

Would you try to fetch the TT or OT font from a wxFont structure? That would be required for getting WYSIWYG, otherwise a different font would be selected for drawing on screen and for PDF output. As for integrating with the wxWidgets printing framework, have a look at wxPrintFactory, which is what is used for selecting printing frameworks at runtime (such as the PS and GNOME print ends under GTK+).

I know. :-) It would certainly add value to wxPdfDocument. > Would you try to fetch the TT or OT > font from a wxFont structure?

As said in step 1 there will be only support for the Adobe Reader standard fonts, that is, Helvetica/Arial, Times Roman and Courier, meaning in most cases NO WYSIWYG. In step 2 and 3 I plan to fetch the TT or OT font from wxFont, that is, I have to locate the TT or OT font file and to extract all needed information from those files "on the fly". The latter represents the hard part, since for the current version of wxPdfDocument this font information has to be generated in advance. Since wxPdfDocument already supports subsetting for TT fonts, which requires some analyzing of the TT font file, I'm pretty sure I manage to extract all needed information without introducing new dependencies (on the freefont library for example). For OT fonts the situation is more difficult. Currently wxPdfDocument supports OT fonts in Unicode build only, without subsetting. I don't know much about the internals of OT fonts so I can't estimate how much work it will be to analyze the font files to the extend needed by wxPdfDocument. > As for integrating with the wxWidgets printing framework, have > a look at wxPrintFactory, which is what is used for selecting > printing frameworks at runtime (such as the PS and GNOME print > ends under GTK+). Thanks. I'll take a look. Full integration with the wxWidgets printing framework will probably be step 4 (or 3 if I postpone OT font support).

Can you provide any details about the rest of the planned DC-like functionality? [ FYI - In case you're soliciting input, priorities, etc... ] As someone who is producing *large* printouts (Maps, etc), I'm especially interested in line/polygon/image handling, etc. Additionally, the real silver-bullet that I'm looking at the wxPDFDC (?) for is proper/native support for alpha (transparency) while printing. Rasterizing to do a large printout isn't practical (Consumes huge amounts of memory), and other vector approaches (PS) don't support alpha. PDF is the best looking solution I see! [ Unless someone else has a better solution? ] Thanks for any info!
