ICC on color picker
by Felipe Sanches 23 Jun '09

23 Jun '09

JonCruz, I've been looking at the dropper-context.cpp code. It deals with sRGB colors only. I think that we should be able to pick an ICC color using the color picker. But there are some issues here: 1) the color picker acquires the rendered sRGB image of the document (a NRPixBlock) and colects the color of a single pixel (or an average). These pixels can be the result of compositing various layers of semi-transparent objects. We will need to implement icc-color compositing on our own if we wish to pick an equivalent color in the transformed color space. 2) Colors can be altered by filters, which are calculated in sRGB. So, it wouldnt be possible to pick an equivalent ICC color even when we are trying to pick a color from a filtered object that has an icc color in its fill or stroke. 3) how to deal with compositing of mixed color spaces? I.e. how to mix sRGB with icc transformed colors? Or even... how to mix colors in two (or more) color profiles? This seems to be hard to solve... I'd like to know what's your (JonCruz and Inkscape devel team) opinion on that subject. Juca

OFF-TOPIC: about your mailing list
by Ocetalo 22 Jun '09

22 Jun '09

Hi there! I'm a member of a national organization here in Colombia, which is promoting a candidate for next presidential elections. This org has got Groups in several Departaments, and each Group has got several commitees. I'm suggesting them to use a mailing list to enhance communications among commitees, Groups and the whole org. We'd like mailing lists like yours, with a single addres for every list (like your @lists.sourceforge.com) and one list for each commitee (like your inskcape-devel, inkscape-user, inskcape-translator...). I know your list is powered by Mailman, but I'm far from skilled at such. I need something free (we're lacking resources), easy and web based (I have no computer of mine, I work on Cyber-coffees). Could you please help? I really appreciate your opinions.

EAN-13 barcode generation success :-)
by Daniel James 22 Jun '09

22 Jun '09

Hi all, Further to the recent bugfix on the generation of EAN-13 barcodes, used for book jackets and many other kinds of product packaging, I wanted to carry out some real-world tests. I printed a real ISBN for a forthcoming book in EAN-13 format on to a sheet of plain 80g/m2 copy paper using Inkscape and an ordinary HP Laserjet 3050 desktop laser printer. I then took the print to my local library, who scanned it for me using their hand-held barcode scanner on the borrowing desk. The library computer recognised the EAN-13 on the first swipe, and decoded it back to a ten-digit ISBN. I'd like to thank all the Inkscape developers for this killer plugin. Cheers! Daniel

Utility of "PLACEHOLDER, do not translate"
by Lucas Vieites 22 Jun '09

22 Jun '09

Hi, I'm wondering if the string "PLACEHOLDER, do not translate", which (IIRC) was included for use in the experimental gtkmm interface is still useful. According to the inkscpa.pot file it's used in: #: ../src/ui/view/edit-widget.cpp:330 ../src/ui/view/edit-widget.cpp:335 #: ../src/ui/view/edit-widget.cpp:343 ../src/ui/view/edit-widget.cpp:348 #: ../src/ui/view/edit-widget.cpp:353 ../src/ui/view/edit-widget.cpp:368 #: ../src/ui/view/edit-widget.cpp:381 ../src/ui/view/edit-widget.cpp:386 #: ../src/ui/view/edit-widget.cpp:400 ../src/ui/view/edit-widget.cpp:404 #: ../src/ui/view/edit-widget.cpp:412 ../src/ui/view/edit-widget.cpp:416 #: ../src/ui/view/edit-widget.cpp:420 ../src/ui/view/edit-widget.cpp:756 #: ../src/ui/view/edit-widget.cpp:761 ../src/ui/view/edit-widget.cpp:867 #: ../src/ui/view/edit-widget.cpp:871 ../src/ui/view/edit-widget.cpp:992 Do not get me wrong, this is merely an "ego thing". If I can't translate this string, the translation will never be 100% ;-) Cheers, -- Lucas Vieites

icc-color on feflood filter
by Felipe Sanches 20 Jun '09

20 Jun '09

I have coded (in my gsoc2009_color branch) icc-color handling in the feFlood SVG Filter. There is no way to set an icc-color for the flood-color parameter in our current filters user interface. But it will properly color-transform an icc-color if it is declared in the SVG file. I have manually edited an SVG file in order to test it. JonCruz, I'd like to ask for your code review of svn revision 21632. Am I doing it right? Should I keep doing it in other portions of the code? Juca

Inkscape 0.47pre0
by Ted Gould 20 Jun '09

20 Jun '09

I've made a pre-release to signify our increasingly frozen state. This image is more intended to help packagers to ensure that our tarballs are of good quality to make packages and to help users find bugs so that we release with as few as possible. This is not recommended for production work. === Tarballs and zips === https://sourceforge.net/project/showfiles.php?group_id=93438&package_id=991… === MD5 Sums === 7c794ec299573da3769dbcab1ff73182 inkscape-0.47pre0.tar.bz2 4ce7b7c349f5999ff4b233d952c132c7 inkscape-0.47pre0.tar.bz2.asc cd38689df58b7e37d17b69639fa4076b inkscape-0.47pre0.tar.gz d71511bc4684ff7204ec6c0c3dc789c4 inkscape-0.47pre0.tar.gz.asc 71cb667999b1cabac197c951a52e8219 inkscape-0.47pre0.zip ae6d202080e22334b3188f10814ed328 inkscape-0.47pre0.zip.asc I think that's it.

0.47-pre0 - Win32 Installer?
by Joshua A. Andler 19 Jun '09

19 Jun '09

Hey all, Do we have anyone who is willing to do the magic to create a 0.47-pre0 installer for Windows? It would be incredibly helpful for testing if this would be possible (think of the non-geeks). ;) Cheers, Josh

Some insight into crash in EAN13 barcode generator
by Daniel James 18 Jun '09

18 Jun '09

Hi all, I was excited to see the barcode generator plugin in Inkscape 0.46, finally I can make my own EAN-13 barcodes for book jacket designs :-) I ran into this bug though, while testing 64 Studio 3.0 beta 3, which is Ubuntu Hardy LTS based. The Inkscape package is the same binary as in Hardy. https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/334073 I think I found the cause, a bug in the plugin. If you select Barcode Type as EAN13 and enter 13 digits into the Barcode Data field, which is correct according to: http://en.wikipedia.org/wiki/European_Article_Number you get the error as shown in the Launchpad ticket. If you enter any number of digits other than 12 or 13, it warns: Can not encode '97819050823' into EAN13 Barcode, Size must be 12 numbers only No barcode was generated However if you enter the first 12 digits of an ISBN-13, Inkscape will generate a bogus EAN-13 barcode, which will probably not scan in book stores because it has the final checksum digit missing. I think there's been a mix-up between 12 digit UPC barcodes and 13 digit EAN-13 barcodes used for book ISBN's. Sorry if this is too obvious and you knew about the problem already. If anyone has a barcode scanner available, I would love to do some quality control testing on this feature, because once it's printed on the back of the book, it's too late to change :-) Cheers! Daniel

Readability of user visible messages
by Alexandre Prokoudine 18 Jun '09

18 Jun '09

Hi, It would be great if somebody for whom English is a native language could go through user visible messages and take care of those unclear of them. I'm specifically referring to live paths effects, which is full of things that are difficult to understand. For instance, Celtic Knot has two options: "add stroke width to interruption size" and "add other's stroke width to interruption size". And we still have a lot of places where it's not clear in what units of measure the function works. "Fuse nearby ends" in Pattern Along Path LPE is one of them. Varios SVG Filter primitives too... Would be great to have that sorted out before strings freeze. Alexandre
