Do I understand that your design for Pango will not call the render_glyph_func at all, i.e. we can leave it as NULL until we've figured out how to do things properly? Richard.

Of course Inkscape should be using the Cairo backend, we just don't at the moment. The difficulty we're having is that not enough of Inkscape's rendering has been converted to Cairo for it to be easy for us to use Cairo's user-fonts for output. Do you think it would be possible for us to create a fake Cairo user-font which only has a partially-implemented render_glyph_func (returns the extents but doesn't draw anything) and then we figure it all out later and send it to our own renderer? I'm just looking for a more incremental approach to this feature rather than having to bundle in a complete Cairo conversion at the same time. Changing the subject slightly, I can't see any mention of kerning in the current Cairo API. Is this something for later, or am I just ignoring things right in front of me again? Richard.

PDF import crash, but not in 0.46

Hi all, PDF import crashes for me on Windows with current trunk. It does not crash in the Inkscape 0.46 binary that I just downloaded. Have all windows patches been applied to trunk? Thanks, Johan

Request for translation SVN commit rights
by Domas Jokubauskis 14 May '08

14 May '08

Hello, I have been using Inkscape for a couple of years now and it have been a great experience. Thank you! I'm passionate about getting proper Lithuanian language user interfaces so I did a substantial update of Lithuanian Inkscape translation for version 0.45.1. I would like to continue my work on future releases but sending changes to the mailing list and asking others to commit them is counter-productive. Thus, I would be grateful if the project's admins granted me the permission to commit changes to lt.po file. My SF.net e-mail: domasj@...58... -- Domas Jokubauskis DomasJ@...1970...

unicode<->glyphid mapping
by Felipe Sanches 13 May '08

13 May '08

I am working on nr-arena-glyphs.cpp there, at line 468: NRArenaGlyphs *g = NR_ARENA_GLYPHS(child); g->glyph holds an integer (the glyph id). As I understand it, there must be a mapping between a unicode char and its respective glyph id. How can I retrieve it? Juca

Reading through that bug I'm unclear whether the proposed pango_font_description_set_domain() function could be used to support a user-font which wasn't also a Cairo user-font. Could you clarify whether it intended to be able to use this feature without being required to use Cairo? Richard.

Looks like that pango stuff would probably help what I was doing, too. I never got to worrying about rendering fonts, just representing them in the SVG file.

buildtool again
by Bob Jamison 13 May '08

13 May '08

Hi again. I left something out of buildtool yesterday, that broke the cross-compiler build on a linux box. Buildtool was not handling recursive substitutions, like: a = "Hello, ${b}" b = "earth, the third ${c}" c = "planet" This is slightly more work to do at execution time than at read time. command="${archutil}windres" archutil="${arch}" arch="i686-pc-mingw-" ...was not working. But it's fixed now, and has that pleasant late-binding smell. Sorry if this broke any cron jobs out there. ALSO: Does anyone know what might be causing this warning? I was afraid to touch it: http://rafb.net/p/34eJBu54.html bob
