problem (bug?) while importing LilyPond pdf in inkscape 0.47 / osx 10.6.2

Hi, I'm trying to import some pages of pdf files generated with LilyPond. I need to import the scores as pdf, ps or eps because there are built-in postscript drawings that could not be generated by LilyPon's svg backend. I have made a copy of LilyPond OTF fonts into /Library/Fonts (have also tried ~/.fonts and ~/Library/Fonts)... (the files are: CenturySchL-Roma.otf CenturySchL-Bold.otf CenturySchL-BoldItal.otf CenturySchL-Ital.otf emmentaler-11.otf emmentaler-13.otf emmentaler-14.otf emmentaler-16.otf emmentaler-18.otf emmentaler-20.otf emmentaler-23.otf emmentaler-26.otf emmentaler-brace.otf) I can use these fonts if I start a new document in InkScape, but it fails to find the fonts if I try to open or import a pdf page. It seems to be an "import" issue, because I can open these files in Illustrator (I don't want to use it) and the fonts are recognized by the inkscape if I try to create new texts... Could it be a Inkscape/import bug? Does anyone have any suggestion about how to load the ps/pdf/eps lilypond documents? thanks, josé -- http://zepadovani.info

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

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
by William Oquendo 04 Jun '10

04 Jun '10

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
