Parallel build on Windows
by Diederik van Lierop 16 Nov '08

Hi, Can anyone tell me how to do a parallel build using mingw32 and btool on Windows? I've tried adding -j4 to build.xml, but that parameter is not being accepted. I'm bisecting, but this could be so much faster on my quadcore... Diederik

Inkscape cannot open *.svgz (compressed Inkscape) through File -> Open (command-line works ok though)
by Michael Park 15 Nov '08

15 Nov '08

Hi there, I noticed that Inkscape bails w/ an error message 'Failed to load the requested file <filename>.svgz' when trying to open a compressed Inkscape file through the GUI. However, it can still load the same file just fine if I pass it to inkscape through the command-line: $ # this works ok $ inkscape myfile.svgz ...when it errors out, I get the following error message on the command line: Entity: line 1: parser error : Start tag expected, '<' not found � ^ To reproduce: 1 - create a new file 2 - add a shape (I just did a simple red square) 3 - save as 'Compressed Inkscape SVG (*.svgz)' 4 - close and re-open inkscape GUI 5 - in the GUI, File -> Open <your saved file> // this will result in the error 6 - open same file through command-line // this will open ok I don't know how long this behavior has been around, I only started using compressed SVG's recently, but I see the behavior as far back as rev 20150.. I also keep rev 19967 handy (there seems to have been a performance regression since this build, when zooming in/out.. the canvas seems to refresh slower... but that's another matter altogether), and it suffers the same problem BOTH through the GUI and command-line. I'll try bisecting down to the neighbor revs that fixed the command-line opening problem when I get some time later on tomorrow. --Mike

Re: [Inkscape-devel] Adjusting DPIs for a document (S?bastien)
by Guillermo Espertino 15 Nov '08

Sebastien: You can work with inkscape's default units (px) and export your artwork at 90dpi from the png exporter and you'll get 1:1 conversion of vector pixels to raster pixels. The same applies to the image imports, inkscape will take the real pixels and place them on the work area using 90 dpi. Of course the feature that you're proposing is interesting and would be very helpful in several situations. This has been already discussed and if I remember correcly, there is a similar suggestion in the wishlist. Could you please check in the bug tracker if it has been already reported? If not, you can create a detailed feature request. Gez.

Grid snapping slowing down operations
by Sébastien 14 Nov '08

14 Nov '08

Hello, I'm using Inkscape grids extensively and some operations like resizing a rectangle or drawing a line using the pen tool push my CPU to 100% for 10 to 30s. The grid setup I use it the following: - Pixels - Origin: x=0.0, y=-15.0 - Spacing: x=2.0, y=2.0 - Step: 10 lines And then snapping is turned on for nodes and snaps to paths, nodes and guides with a distance of 1. I've been experiencing these slowdowns on two Ubuntu machines, and the problem still shows with the latest realase (8.10). I'm running Inkscape 0.46, built Oct 24 2008. -- Sébastien

Adjusting DPIs for a document
by Sébastien 14 Nov '08

14 Nov '08

Hello, I'm doing UI design using Inkscape and it is important for me to be able to adjust the DPI on a per-document basis. In practice, I want to be able to adjust the number of pixels per inch (or cm) so that I can make UI wireframes bigger or smaller without losing the pixel-precision. -- Sébastien

Hi Jasper, Probably you intended to send this message to the dev-list too? Thanks for your info on gcc vs. make. Probably Bob will comment on this. Anyway, Eclipse already has the automatic build option you described. When I first tested it two years ago it didn't run very smoothly for large projects such as Inkscape, but things might have improved (at least my CPU has), so maybe I should try it again.

[PATCH] Fixing strings when exporting to JavaFX files
by Silveira Neto 13 Nov '08

13 Nov '08

Some exported codes couldn't compile in JavaFX due to spaces and minus signs on id labels. The sanatize function creates a new string with them replaced by underscores, solving the problem. Diff agains revision 20175.

Inkscape book on Floss Manuals
by Joshua Facemyer 13 Nov '08

13 Nov '08

A little PR for the Inkscape Docs team: We recently got our Inkscape Manual (the fruit of our Book Sprint) put on Lulu (http://www.lulu.com/content/4617381). You've probably seen the article by the Russian on the inkscape.org which has a link - if not, check it out! The published book, while being a reasonably finished work of good quality, is not comprehensive. We would like it to be more so. Here are some things that will help us to continue with this work: 1. Sales of the current version (somewhat limited 1st EDITION!!!!) on Lulu will help us afford a future Booksprint. 2. Contributions to the manual on our Floss Manuals workspace are greatly needed. Of course, as this needs some coordination, it's best to start on the inkscape-docs list (signup at lists.sourceforge.net) to find out where to begin. 3. Magical powers to generate whatever good thing we want without much effort. If you can help with any of these things, that would be GREAT! In particular, getting word out and posting the link to the Lulu store would be of great benefit. JF
