flattening transparency
by Aaron Spike 21 Feb '06

21 Feb '06

I've been trying to educate myself about our printing problem by exploring cairo, librsvg, the uberconvertor and pdf in general. I stumbled across this document entitled, "Achieving Reliable Print Output from Adobe Applications when Using Transparency." http://partners.adobe.com/public/asn/en/print_resource_center/TXPGuide.pdf It seems to me that most all of the functionality needed for flattening out transparency already exists in Inkscape. A rather brute force method could be: 1) Replace all strokes with paths 2) Decompose all overlapping objects (this would be an additional boolean op, and it has been requested twice in my recent memory) 3) Replace all area's of overlapping transparency with a bitmap copy. 4) Replace all non overlapping transparency with the resultant color. Further optimizations would of course be possible. My exploration of cairo and librsvg has only been very casual, but I can't imagine that either of them will be well suited to this sort of decomposition task. But maybe with all of the recent excitement and advancement around vectors a good LGPL computational geometry library will pop up. Aaron Spike

Private Use Area

The library is doing the right thing. In and of itself, any private use character could be printable or non- printable, and is not covered by the specs or such functions. If our application can deal with the Private Use Area (which I've verified we do), all we need to do is check for it. g_unichar_validate () then g_unichar_type(..) == G_UNICODE_PRIVATE_USE will take care of things the right way. Aside from other issues, this makes Inkscape's input behavior consistent with other systems, including the built-in OS X method. (Tricky to find, but easy to use once it's checked). Of course, this led me to wonder if we might want to warn upon insertion of a Private Use Area character. I'm attaching a quick sample that shows the use of two private area characters (the second being the Apple glyph). This is happy-happy for me here in Inkscape and FireFox.

Some warnings on hidden virtual functions, deprecated functions, and template issues. (Btw, the test harness has been offline for a while - it had just run out of disk space. I cleared space, so it should be good for another month or so.)

Swatches Scrollbars
by Jon A. Cruz 19 Feb '06

I did a minor re-work on the panel stuff, and got the horizontal scrollbar to disappear on the swatches when it's embedded in the main UI. Take a peek and see if it helps any.

CC your answer to the submitter name: Adrian email: adrian.adm@...1182... submitted the following: I would like to check with you if you have any objections to our distributing some of your software on CD. We have found that many students have only access to a dial-up internet connection (or none at all), and so would like to be able to supply our students with a CD of the software that they may find useful as part of their studies. We have chosen the following software from your organisation to go on this CD: Inkscape You can find more information of the (fledgling) web site at www.springstep.co.uk. We hope we have made it clear that we have absolutely no rights over this software, and are providing links back to your web site for license terms, updates, and possibly, to purchase the paid-for version. All serials, registrations etc. would be handled through your web site in the normal way, as we will only be supplying the installation executable. You may, at the moment, see your software listed on the web site - please be assured we have released no discs so far that contain software to which you have not expressly agreed. We hope we will be able to provide the software shown above, and to be able to encourage and teach students in the use of it. Thanking you in advance for your consideration, Adrian

Strange behaviour of translation
by Lucas Vieites 18 Feb '06

18 Feb '06

Hi, from some time ago I'm having trouble testing my translation of Inkscape. I update from svn and the po file is completely translated (only a few strings are missing, but they belong to a filter/effect). I do the usual $ ./configure --prefix=/var/opt --with-perl --with-python $ make $ make install And when I run /var/opt/bin/inkscape I find that many of the strings that used to be OK in previous versions are now in english. I checked that the correct inkscape.mo file gets loaded, this command: $ strace inkscape 2>&1|grep open.*inkscape\.mo shows this: open("/var/opt/share/locale/es_ES.UTF-8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/var/opt/share/locale/es_ES.utf8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/var/opt/share/locale/es_ES/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/var/opt/share/locale/es.UTF-8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/var/opt/share/locale/es.utf8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/var/opt/share/locale/es/LC_MESSAGES/inkscape.mo", O_RDONLY) = 4 open("/usr/share/locale-langpack/es_ES.UTF-8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale-langpack/es_ES/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale-langpack/es.UTF-8/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale-langpack/es/LC_MESSAGES/inkscape.mo", O_RDONLY) = -1 ENOENT (No such file or directory) So the only file it finds (/var/opt/share/locale/es/LC_MESSAGES/inkscape.mo) is the correct one. Most of the strings I find in english are in the "Document Properties" dialog, see screenshot here: http://www.asixinformatica.com/files/inkscape_properties.png I hope it's no big probem ;-) Cheers, -- Lucas Vieites Fariña <lucas@...212...> Web: <http://www.asixinformatica.com/users/lucas/> Blog: <http://www.asixinformatica.com/blog/>
