Hi Nathan. I do a deeper look. ///////////////////////////////////////////////////////////////////// El mar, 13-05-2014 a las 03:40 +1000, Nathan Hurst escribió: 1) to my old astigmatic eyes the tangents do not look like they are > quite matched, are you sure you have the tangent code correct.

Maybe the problem is how far is the tangent handle from a node, but there isn`t a perfect way to determine, it depends from case. I use the nearest point to the tangent from a point placed at a half distance from the real knot filleting to the original cusp node.

This is my opinion but if anybody want to tell me about, i could change ;) Thanks Nathan for the feedback.

Re: [Inkscape-user] text in export to pdf randomly garbled

by Ronald Klop

Hello, I compiled Inkscape on FreeBSD and I can't reproduce my problem there. So it seems to be in some code which only runs on Windows. Any hints? Should I better post this on the inkscape-developers list? Regards, Ronald.

Re: [Inkscape-user] [Inkscape-devel] New LPE, New Video. Fillet/Chamfer

by Jabiertxo Arraiza Cenoz

Hi Nathan. > Fantastic work, Jabiertxo! Thanks very much > Something to think about: If you were writing the curve editing/handle > code from scratch, how would it work? Firts to the end: Not realy a code from scrach. it have a lot of code from Power Stroke, without this i couldent make this. Power Stroke store in a vector of Geom::Point the data of his knots, basicaly in the X coordente store the position in the line and in the Y coordinate store the distance from knot to original line in perpendicular. Also have acallback in node tool for handle updates on the original path. Whith this base i work the effect. The work in progres add new features to the original concept whith the feedback of suv, LiamW and ScislaC. I put the ended result: I need to store: Distance from Knot to path: Stored in the [Y] part. it determine how far is the knot to the path -configurable by LPE widgets- in poxels, from 0 in the same path, in away. this is because with some zoom knots hide nearly Nodes and need a way to move a bit. It reply your 3 question Hide or show knot: Knots only show in cusp nodes so [Y] negative values in symm nodes... make the knot invisible. Fillet or Chamfer: It also is handled by the [Y] part of the Geom::Point. The [Y] value can be an floor(double) or a floor(double)+0.0001. In case there is decimal part, the effect show as chamfer. If a knot radius is in mode flexible (green knot): Store in the X value of the pathvector (int)index_of_pathvector +(decimal)0.-1 point at this curve. the next curve radius is calculated by the phisical distande in previous. If a knot radius is fixed (red knot): It still store the value in X but is stored in pixels -whith unit conversions- and with a negative value for easy check. This knots are exactly the X value in pixels*-1 in both sides. > 1) to my old astigmatic eyes the tangents do not look like they are > quite matched, are you sure you have the tangent code correct.

Why? Replied. Thanks Nathan for the feedback. I send news soon whith the active points. Sorry for my english. Regards, Jabier.

text in export to pdf randomly garbled

by Ronald Klop

Hello, I have a couple of technical drawings which I convert from Microstation (.dwg) format to SVG using some third party software and from SVG to PDF using Inkscape. The SVG contains the text on the drawing in correct form, but the PDF has text garbled. It is displayed ok, but the text selection for copy-pasting is corrupt. It is reproducable and the result is constant for every run. If I use the --export-latex option than the .tex file contains the text in correct form again. Is this a known issue? I cannot find it in the bug database. I'm running Inkscape 0.48.4 and also tried the latest development binaries from your site. I reproduced this on Windows Server 2008 R2 Enterprise and Windows 7 Professional. Both 64 bits. I can provide a sample drawing, but need to anonymize it first. Regards, Ronald. -- Ronald Klop

New LPE, New Video. Fillet/Chamfer

by Jabiertxo Arraiza Cenoz

Hi to all. Here is a video showing my new LPE. The branch is here[1].The video here[2]. Thanks to Josh Andler for give me the idea Also thanks very much to suv for the feedback and time inverted on it. And a special thanks to Liam P. White, without his help the LPE need a lot of hours to be.. or not to be. Bye, Jabiertxo.

putting youtube on an svg web page.

by john Culleton

I know I can create an svg web page via Inkscape. I can add url anchors to it. But can I by any mechanism put a Youtube video on it or do I have to use an html subpage and an url anchor to reach it? -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Settings on windows 8 - multicore support.

by Martin Acevedo

Hi, I'm using a the tool for a few days and it looks great. I have noticed from time to time it gets a bit slow. I googled and found it is possible to add multi - core support, at least on linux. The thing is I'm running windows 8 and I don't know if this is possible. In addition, there is no "%userprofile%\Application Data\Inkscape" in my windows. Does anyone know where the settings are stored? I'm using 0.48 version of inkscape. Thanks, Martin
