Sample file request: R->L and T->B languages, in a couple of file formats
by mathog 05 Oct '12

05 Oct '12

It would be a big help to me in getting the EMF sections of the code right if some developers who uses an R->L language and a T->B language could prepare a set of samples similar to the files listed below. Then email them to me. But before actually starting work on this please post back to the list first saying you will be doing this, so only one person needs do this for each language. Samples are only required for one R->L and one T->B language. These samples don't need to be a 1:1 translation from English - I probably won't be able to make any sense of what they say anyway, but it is important that the starting document edited normally in PowerPoint in whichever language you use, since that will likely affect what the emf file will look like internally. Examples of what I need in English are in these files: http://saf.bio.caltech.edu/pub/software/inkscape/formatted_text_en_test.ppt http://saf.bio.caltech.edu/pub/software/inkscape/formatted_text_en_test.emf http://saf.bio.caltech.edu/pub/software/inkscape/formatted_text_en_test.png http://saf.bio.caltech.edu/pub/software/inkscape/formatted_text_en_test.svg I used Arial font which I think has support for most common languages, at least on Linux. Left,center,right justification will look more or less the same (at a distance) in a R->L language. That is, the same parts of the screen are written, just different characters. For a T->B language I believe Left justify slides to the top. The near collision of the text blocks at +45 and -45 degrees is intentional, please do that in the other languages too. The samples from other languages do not need to have the text in exactly the same positions as the English samples. The English language sample files were made as follows. 1. Compose the file in Powerpoint in a standard slide. Be sure to put a slide sized rectangle on the bottom or step (2), below , will not scale correctly: http://saf.bio.caltech.edu/PPT_G_P_I/#P2I_method Save the presentation as a *.ppt file. 2. In PowerPoint, in that slide window select all right click one selected object save as picture. (give it a name and use "Enhanced Windows Metafile" to create the *.emf file). 3. Take a screen shot of the PPT slide, or of the EMF in Windows Preview, and save as PNG to make the *png file. 4. The SVG in the example was constructed by hand so that text would be at least somewhat editable. EMF import was not used because the text ends up in many little pieces, ie: http://saf.bio.caltech.edu/PPT_G_P_I/#I2P_formatted_strings To make the SVG in Inkscape I suggest: format a 10 x 7.5" page, then import the *.png into it, align it to the page, and lock it. If the underlying rectangle was used in step (1) then the PNG will be exactly the right size. Then create a second layer above the first, enter text to match the underlying PNG. Easiest if the underlying text is black, and the upper layer is red. I used vertical kerning for super and subscripts, because it was not otherwise possible to match those character positions. When the overlay is done, remove the lower layer, change the text to black, save to make the *svg file. Thank you, David Mathog mathog@...1176...

Building .app on Mac OS X with Macports
by Frank Schima 04 Oct '12

04 Oct '12

I'm trying to build inkscape 0.48.2 as a Mac .app application using Macports. I'm on Mac OS X 10.7.3 with Xcode 4.2.1 and Macports python 2.7.2 with numpy and lxml. According to the wiki page [1], I should use the osx-app.sh shell script to create it. So I attempted to run the script as stated in the wiki but it did not work for me, saying that it wants the python modules directory to be specified. $ pwd /opt/local/var/macports/build/_opt_mports_trunk_dports_graphics_inkscape/inkscape/work/inkscape-0.48.2/packaging/macosx $ ./osx-app.sh -s -b /opt/local/var/macports/build/_opt_mports_trunk_dports_graphics_inkscape/inkscape/work/destroot/opt/local/bin/inkscape -p ../../Info.plist CREATE INKSCAPE APP BUNDLE Python modules directory not specified. Python modules can be downloaded from: http://inkscape.modevia.com/macosx-snap/Python-packages.dmg So I next attempted to specify the python directory. $ ./osx-app.sh -s -b /opt/local/var/macports/build/_opt_mports_trunk_dports_graphics_inkscape/inkscape/work/destroot/opt/local/bin/inkscape -p ../../Info.plist -py /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages CREATE INKSCAPE APP BUNDLE Directory does not appear to contain the i386 and ppc python modules: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages Python modules can be downloaded from: http://inkscape.modevia.com/macosx-snap/Python-packages.dmg I tried the download link but that does not resolve. Can anyone tell me what I'm doing wrong, and more importantly how I can build inkscape as a Mac .app with Macports? Cheers! Frank [1] <http://wiki.inkscape.org/wiki/index.php/CompilingMacOsX>

Swatch/Palette border
by John Smith 04 Oct '12

04 Oct '12

Recently committed some options for the Swatch/Palette border (Swatch/Palette popup menu Border->None/Solid/Wide). I think there is a good case made (both user acceptance and better distinction) for setting the default border to solid black in the below bug report. Any interest in changing the default border ? https://bugs.launchpad.net/inkscape/+bug/171177

extension help requested
by Mark Schafer 04 Oct '12

04 Oct '12

I'm modifying the nicecharts extension to make more charts and 'improve' some aspects. It now reads many lines and columns in a csv file to make several graphs at the same time. Its going very well except for this one problem: - when I feed it too much data inkscape locks up and does not respond. The amount of data is suspiciously low. Can anyone help me to debug it. What am I doing wrong ? - I have fixed a problem where lots of unused filters were being made. - I'm pretty sure I've got my layers and groups being made correctly. - The log shows the file runs to completion without errors but control never returns to the users. - To show the problem, 2 data files are available. one is good one is not. Code logs to file for examination. You will need to modify the logfile location at top of nicecharts.py for your system. Code is here: http://pastebin.com/6b8jcanU inx is here: http://pastebin.com/u3znJNrR you also need support code: http://pastebin.com/YKCdWJYS datafiles: good - http://pastebin.com/7xL4cf8b failure - http://pastebin.com/sqTXb8bd rename the files: nicechart.py nicechart.inx nicechart_colors.py

Re: [Inkscape-devel] Method to get from (font,string) to exact width?
by mathog 28 Sep '12

28 Sep '12

Well, hours later, and I still couldn't figure out where Inkscape hides its table of fonts/font properties. Another one of those cases where it is faster to write something from scratch than to figure out where it is buried in existing code. The attached small test case does the desired sort of calculation and works on both linux and Windows (mingw, with devlibs32 installed for freetype and fontconfig.) The first time it ran on Windowx XP it took about 30 seconds, presumably because it was making the font cache. Subsequent runs were fast. Found the cache file(s) in: C:\Documents and Settings\Local Settings\<username>\Apps\Temp\fontconfig\cache Strange file names, starts with a long string of hexadecimal characters and then ends in ".cache-2" or ".cache-3". Today's was 456KB and one from two days ago was 935KB. Not sure which other application made the older one, nor why that one was twice as large. Regards, David Mathog mathog@...1176...

Sorry about the threadjacking
by mathog 27 Sep '12

27 Sep '12

Apparently my practice of starting new threads by replying with a changed subject was not sufficient to actually start a new thread for some mail readers. I wasn't aware of this issue until one of you just told me, as my mail reader doesn't thread like that. My apologies to all of you whose threads I have accidentally highjacked this way!

Grayscale mode
by Johan Engelen 24 Sep '12

24 Sep '12

Hi all, Early in 0.49 development I added the grayscale viewmode. Very convenient for preparing figures for both color and grayscale print output. With the change to the renderer, we lost the functionality. Is anybody willing/capable of restoring the functionality? Thanks, Johan
