Further requests for assistance with Python extensions
by Jon 10 Jun '10

10 Jun '10

I'm now in the process of optimising and documenting my Inkscape extensions that implement the International Orienteering Federation mapping standards. There are some areas of the extensions that I would like to improve to make them more universal / intuitive. 1) Currently, a number of my routines apply formatting and patterns of tags or dots to paths (strokes). I would like to extend the routines to also be compatible with rectangles and arcs / ellipses. I assume that the routines to do most of what I want already exist in one or other of the 'helper' files like cubicsuperpath, pathmodifier and simpletransform, but as yet I've not worked out how to make them work for me. I need to understand how to implement the following from within a Python extension: a) Convert a rectangle to a path. Will rectToPath in pathmodifier do this and, if so, what do I need to provide for self amd node? b) Convert an arc/ellipse to a path. Will ArcToPath in cubicsuperpath do this and, if so, what do I need to provide for p1 and params? 2) I also need to understand how to apply a transform to a path (i.e. embed the transformation into the path so the transform is not required) so that effects applied to a heavil transformed path (as can happen when using ellipses / arcs) are applied correctly. Will one of the routines in simpletransform do what I want and, if so, which one and what would I need to supply to it? 3) I still need to provide the capability via an extension to convert a line into two lines of a given line width and a set distance apart. This will need to work with curved paths, both open and closed. The way that I would do this manually in Inkscape would be to create a stroke, duplicate it, set the widths of the two strokes such that the lower is the width of the two lines plus the gap and the upper is the width of the gap, convert both strokes to paths using Path - Stroke to Path and then to use the Path - Difference function to leave two lines of the required width and separation. How could I go about recreating this from within a extension? Is there an easier method to do this, given that the two lines should not be joined at the ends? Still outstanding from a previous request are a couple of unanswered questions (rephrased): 4) Ho would I go about detecting whether a point lies within the bounds of a closed shape passed to a Python extension? Is there an existing routine in one of the Python extension 'helper' files that can do this? 5) How would I go about implementing a method to detect collision / distance between dots from within an extension? I'd like to implement something similar to the 'Remove Overlaps' capability available within the 'Align and Distribute' dialog as part of the routine generating the dots, but with a single (polar - sqrt(x^2 * y^2)) variable related to the user-selected dot density determining how close the dots can be placed to each other. I can see that this could get complex when the area, and hence the number of dots, gets large. With regard to these last two, I believe there may be something possible using py2geom, but where do I find details of this? What are its capabilities and are they documented anywhere? ----- Jon

Inkscape 48
by John Culleton 10 Jun '10

10 Jun '10

I have Inkscape 47 installed on my Slackware Linux 13 system. Is Inkscape 48 stable? If so how do I download the source? If it is not stable what is the address for the svn version of Inkscape? I update Scribus nightly so I might as well do the same for Inkscape. -- John Culleton Wexford Press "Create Book Covers with Scribus" Printable E-book 38 pages $5.95 http://www.scribd.com/doc/24676863/ http://www.booklocker.com/books/4055.html

Unexpected behavior in Inkscape 0.47
by Steve Litt 09 Jun '10

09 Jun '10

Hi all, I ran into some unexpected behavior in Inkscape 0.47, running on Ubuntu 9.10 32 bit. When you duplicate and move diagram connectors, they don't move as expected. This happens on diagrams whose page size and/or orientation has been changed, and doesn't happen when the page size and orientation have never been changed. SYMPTOM REPRODUCTION * Open a new diagram * Create a diagram connector * Click the "select and transform objects" button * File->Document_properties->Page_orientation, change to landscape * Select the diagram connector * Ctrl+D to duplicate * Shift->Right The Shift->right moves the new connector down instead of right. From my perspective this is unexpected behavior and indeed when the page size is left at default, shift->right moves the connector right as expected. MECHANISM OF THE ANOMALY When you change the paper orientation, it puts a "transform="translate(0,-308.2677)" attribute within the <g> node of the Inkscape XML. If you remove that attribute, the anomaly goes away. If you put the attribute back, the anomaly returns. WORKAROUND When starting a new document, do any paper size and orientation settings immediately on the blank diagram, then remove all transform=translate attributes and save. Diagram connectors will then work normally on the drawing as long as the paper size and orientation aren't changed. I have no idea what side-effects this workaround would create, but I haven't observed any. WHAT I'VE DONE This looks to me to be something like bug number 479553, "Moving shape with connectors, connectors go wild", so I appended my findings to that bug report (https://bugs.launchpad.net/inkscape/+bug/479553). MY QUESTIONS: * Is this a known problem? * Is anyone working on it? * Is this fixed in later versions than 0.47? * Is this considered a bug? * What side effects occur when deleting transform=translate attributes? * Can anyone else reproduce this behavior? * Is the problem that the transform=translate shouldn't be there, or is the problem that connectors don't properly respond to the transform=translate? * Is there anything I can do to help get this behavior fixed?

Re: [Inkscape-user] Extracting sub shapes from bitmaps
by John LeMasney 04 Jun '10

04 Jun '10

William, it would help to see the bitmap or converted path to see if what I'm suggesting will work, but it was scrubbed. Here's what I would suggest. Make sure that your converted bitmap is indeed a single path. You will get feedback about this in the taskbar when you select the object. If it says '1 group' or "two paths" or anything else selected, you must ungroup, etc, until you have a single path. A single path can of course have many many separated shapes in it with space in between them Then, in the path menu, choose 'ungroup'. You should then see your shapes separated into a series of selection boxes all selected at once. Click away with the selector, then select individual circles. If you have overlapping circles, they will become a single object in a single path. Hope this helps.

Extracting sub shapes from bitmaps

Dear all, I have a bitmap with many circles inside it, and I would like to manipulate each circle individually. I have already converted the bitmap to svg by using Trace Bitmap inside inkscape, but I dont know how to "ungroup" the vectorized figure and manipulate the circles individually. I would like to know if I can do that in inkscape and how. I am attaching an example bitmap. Thanks in advance.

SVG Open 2010 conference - Last Call for an Inkscape contribution
by Andreas Neumann 04 Jun '10

04 Jun '10

Hi all, As every year we are organizing the SVG Open conference (http://www.svgopen.org/2010/). This year it takes place from August 30 to September 1 in Paris. Inkscape was always present in the past couple of years through presentations of Jon Cruz, one time also a keynote. His contribution was always one of the highlights of the conference. Inkscape is the most powerful SVG editor we have at hand. It would be very nice if the Inkscape project would be represented at the conference. I am sure there are plenty interesting aspects in Inkscape that would be worth being presented at the conference. If you live close by and have time and interest in presenting Inkscape, both from a developer, but also from a designer/user point of view, you are still welcome to submit a short abstract until June 9. The official abstract submission deadline is over, but we are still accepting late interesting submissions. If you are interested, please submit an abstract at https://www.svgopen.org/2010/registration.shtml (you first have to preregister) or ask me questions, if any. I would hope that the Inkscape project could be present at the conference. Thanks, Andreas

Possibilities with Inkscape extensions
by Jon 31 May '10

31 May '10

I've now nearly completed my project to implement the International Orienteering Federation mapping standards in Inkscape - three mapping standards, one of which has two symbol scales - which has resulted in a large number of extension files. In order to simplify things, I'd like to be able to have, for a given subset of the symbols, four separate INX files each calling the same PY file where a parameter is passed to the PY file, not user selected, indicating which INX file has made the call. Is this possible? Is it possible to specify a variable in an INX file and ascribe a value to it without presenting the user with some form of parameter input? Also, I'd like to be able to produce a routine to fill an inkscape closed shape with randomly sized (between a lower and upper size) and positioned dots where the user can alter the density of dots and where dots will not overlap / touch / be closer than a specified distance between them. This raises a number of questions: 1) Is it possible to specify a slider-type input tool in an INX file? 2) Is there a Python command or a routine in one of the Python extension supporting files (simplepath, etc.) to detect whether a point lies within the bounds of a closed shape? 3) Is there an available routine to determine the area of a closed shape? 3) Are there any simple ways to detect collision / distance between dots? I'd like to implement something similar to the 'Remove Overlaps' capability available within the 'Align and Distribute' dialog as part of the routine generating the dots, but with a single (polar - sqrt(x^2 * y^2)) variable related to the user-selected dot density determining how close the dots can be placed to each other. I can see this getting complex when the area, and hence the number of dots, gets large. 4) Getting more complex, would it be possible to have a gradient-filled shape and vary the density of dots dependent on the gradient? ----- Jon

Expanding text
by George Farris 31 May '10

31 May '10

Hi All, I'm wondering if there are some good text tools in Inkscape or maybe the new .48 version. It seems very difficult to do things such as expanding text where for example the first letter of a word or sentence is say 10 points high and the last letter is 70 points high. Is this easily done? Inkscape seems awesome except for the text tools but maybe I'm missing something. It would be nice to convert a piece of text to one object and distort it accordingly. Not each letter as happens now. Any help or pointers greatly appreciated. Thank You George

inkscape for rapid "paper-based" prototying
by unknown＠example.com 10 May '10

10 May '10

Hi list I use inkscape for "paper-based" prototyping. I use layers for each screen and print them to test the prototype with users. Now I thougth instead of printing I could use inkscape directly. I noticed theres a property dialog for each object. So the question is if it is possible to use the "onclick" action to bring a defined layer to the front. Example: the layer "Main-Menu" is the top layer. On this layer is a button- object "Configuration". If I click on this button, the Configuration layer becomes the top layer. This way I can do exactly the same as I would do printing all layers. Is something like this possible? If someone know how to realize this, I would be very happy to get hint's code-example or whatever it takes. thanks for any hints ~nos

Input Devices Settings in current bzr version not stored permanently
by Alexander Roalter 25 Apr '10

25 Apr '10

The input devices settings (for extended input, e.g. tablet) have changed some time ago to a different format. Now, I can set the stylus device to Screen to have it pressure sensitive as expected, and it is also stored as this in the preferences.xml, but on reload if forgets this setting. My stylus device is called Stylus0, the eraser Eraser0. Setting the eraser to screen mode, in the preferences.xml I see something like <group keys=";;;;;... axes="x;y;pressure;xtilt;ytilt;wheel" mode="screen" id="E:Eraser0" /> but no such entry for stylus or Stylus0 exists and is created... -- Cheers, Alex

Printing problem with imported PDF and added bitmap
by Philip Rhoades 25 Apr '10

People, I am using: inkscape-0.47-2.fc12.x86_64 I: - opened a PDF form - added some text but also my signature - saved the changed form as SVG and exported as a new PDF - sent the PDF to the responsible person (a Windows user) but although she can see the signature on the screen, it doesn't print (I presume she is using an Adobe viewer). I think she was able to get around it by doing a print screen and saving to a doc file? This could be a problem if it happens all the time . . Ideas?

Inkscape symbol templates (newbie question)
by Johnny 21 Apr '10

21 Apr '10

I am relatively new to Inkscape, and am looking to use it for general vector drawings, but in particular drawing diagrams (single line electrical diagrams). As such, is there anything similar (sorry for the comparison) to Visio's symbol templates, where one can store recurring symbols and simply insert them (and create custom symbols to add as the need arises)? Any ideas on how best to manage this in Inkscape (or indeed any other recommendations?) would be greatly appreciated; likewise if there are any single-line symbols available? Thanks, Mattias

For a software development project--particularly one that is physically dispersed and has multiple levels of commit privileges such as most open source projects--Bazaar offers substantial benefits. The Canonical/Ubuntu/Kubuntu/?buntu crew has moved most revision control to Bazaar...because bzr makes it easy for marginally-techies to contribute. This site explains further...http://jam-bazaar.blogspot.com/2007/10/bazaar-vs-subversion.html The leaders of projects are not in cahoots about what system to use for versioning, make-ing, etc. There is no FOSS governing body dictating tool selection. And for every "user like me", there are many users not like you that also have preferences. "Scribus just to be difficult..." Well probably not "just" with the intention of being difficult. It might have something to do with--make is Unix-ish, while Scribus is cross platform. Many users of open source software run on platforms other than ...N*X. Many M$ Office users have abandoned Publisher in favor of Scribus. Chin up, John. These technical details are part of the FOSS fun. 8^) Carl

Text Rasterisation
by Andreas Neustifter 13 Apr '10

Hi! I didn't find anything on the Interwebs, so I resort to here: I have a Inkscape document that has several texts in in and most of them are properly (as text) output to PDF. But there are some that are rasterised and I do not get it why this is so. I have cleaned up the XML and even if I copy the XML style attribute from a properly rendered text to a rasterised one it gets rasterised. Any hints? Thanks so much, Andi
