Help needed: Extensions rotate path
by unknown＠example.com 18 May '18

18 May '18

Hi all, I've been refactoring the extensions code and while working on the paths support, I've become blocked on the rotate path functionality and need help. It's supposed to be able to rotate each of the points in the point list around the center x,y and it's based on the original code. But I have two problems. Firstly, I can't seem to find a way to get inkscape to output the kind of rotated path that would make writing a trustworthy test easier (and I don't know how to do the calculations by hand) And secondly, I'm not entirely sure if the original code worked or not. If you know anything about geometry or the original python, can you take a look at https://gitlab.com/inkscape/extensions/blob/master/inkex /paths.py#L92 which is the code in question and https://gitlab.com/inks cape/extensions/blob/master/tests/test_inkex_paths.py#L124 which is the respective test code. Tests can be run with `python3 setup.py test -s tests.test_inkex_paths` Best Regards, Martin Owens

y-axis direction and origin
by Thomas Holder 05 May '18

05 May '18

Hi all, I took the liberty and assigned bug 170049 "Inverted ruler co-ordinate system" to myself. I used the patch from 2010 as a starting point, fitted it to the current code base and made it user configurable. It's been a while (7 years) that I last contributed to Inkscape development. What's the current development process? Do you guys do code review? How do I submit a pull request to the gitlab repository? I'm not a project member yet (my username is @speleo3). Thanks, Thomas

Performance issue with gtk3 (especially on Windows)
by Eduard Braun 03 May '18

03 May '18

(I'll split this from the previous thread "slow, sluggish drawing with pencil & calligraphy tool solved" which became quite lengthy with a title not really matching the topic anymore) Hi all, I did not have a lot of time to follow up on this lately but I've got some great news I want to share with you regarding the performance issues we were seeing in Inkscape master (especially on Windows due to extremely poor GTK3 rendering performance which got even worse when drawing native window decoration, i.e. GTK_CSD=0). Turns out a patchset for cairo (see [1]) greatly reduced the latency of the rendering pipeline giving Inkscape a huge boost. I just built Inkscape with the patched cairo and performance with GTK_CSD=0 is now even slightly higher than with GTK_CSD=1! Also the blocking behaviour is completely gone (i.e. UI always redraws properly with current unmodified master). Performance with master/gtk3 is still *a lot* lower than with 0.92.x/gtk2, so I hope we can continue to improve Inkscape code (Yale's changes already looked very promising and I think they were not directly related to the changes in cairo, i.e. could improve performance even more) and maybe even GTK3 code (there are some very recent developments [2] which might result in a completely overhauled OpenGL based backend for win32!) but with today's success I finally feel we have a realistic chance to make the next Inkscape fun to work with on Windows! Best Regards, Eduard [1] https://github.com/Alexpux/MINGW-packages/pull/3675 [2] https://gitlab.gnome.org/GNOME/gtk/issues/105

Location path for an imported figure
by David Carrasco de Busturia 02 May '18

02 May '18

Dear All, I am finding `Inkscape` a really good tool for importing `PDF` or `EPS` scientific plots into a blank page, and then place arrows on top of the graphs, text, make scientific drawings assemble them in the desired location and then save as a unique PDF page that can then be included as a unique `figure` in a `latex` document. Let's imagine an inkscape project that has assembled 10 plots, imported from these folders: /path1/plot_1.pdf /path2/plot_2.pdf ... /path10/plot_10.pdf We already know that in /path1/ there is also the python, gnuplot, etc source code that produces the PDF plot, for instance: /path1/plot_1.py /path2/plot_2.gnu etc Most of the times I need to continue working over the original PDF plots that I once imported into a inkscape project I made back in time. For example, change the scale and the title of the plots, and so on. In other words, I need to go to the original source code (gnuplot, python, etc) that produces those plots that have been assembled in the inkscape project. In these situations, while having the nice inkscape project in the screen with all the plots 1 to 10, it is quite hard to remember where is the location of the original PDF plot. As far as I am concerned, there is no option in the inkscape interface that allows you to know which is the original location path of the PDF plot that was once imported into the inkscape project. The closest solution I could find is the following: every time I import a new PDF of EPS, I right click and and create a link which is basically a copy-paste of the location path of the figure. This solution is quite tedious and most of the times one forgets to create the link. Once the image is imported, the next natural step is to resize it and locate in the desired place, and it is very easy to forget to create the link. For instance, if this multi PDF plots assemble project was made in Latex, the location path of all the plots would be perfectly identified, i.e. in the `\includegraphics` line. I am sure there are more than one user that misses this feature. I was wondering if it is possible to check an option in the importing process that would allow to automatically write the location path of the figure somewhere. Or any other strategy that would automatically write the location path every time a plot is imported. Would this be very costly ? Thanks a lot for all your help, All the best, David
