Gtk-apps.org

Hi, I always loved the kde-apps.org (gnome-look,kde-look...) interface and form-factor versus other approaches. Now gtk-apps.org has been created. http://www.gtk-apps.org/ Someone with good English skills could add an entry for Inscape?

Font Variants
by Gail Banaszkiewicz 24 Jul '07

24 Jul '07

Hi everyone, I just wanted to clarify what exactly the problem described in this bug is: 904962 (http://sourceforge.net/tracker/index.php?func=detail&aid=904962&group_id=93…) At first it sounds as though fonts are actually not showing up at all for some platforms, but I'm wondering if the problem now is simply that the UI doesn't separate font family and variants beyond what CSS allows (so no small caps, outline, swoosh, etc). If you can shed any light (and I bet bulia can at least), it will be much appreciated. Thanks, Gail

feImage filter
by Felipe Sanches 24 Jul '07

24 Jul '07

I have been working on feDisplacementMap but I havent figured out a way to test my first drafts of code since the displacementmap test on the SVG 1,1 full test suite also depends on feImage. That sucks! So, I stopped working on fedisplacementmap and started to implement feImage. The specs say that feImage should behave similarly to the image element. So, I imagine that it may be possible to not duplicate code. But I tryied to look at sp-image.cppand I dont know exactly how to reuse it. Could anybody help on this? Juca

Fonts
by Thomas Worthington 24 Jul '07

24 Jul '07

Hi, Is anyone actually working on fixing the font problems (ie, no styles except the very basic ones)? This is a total show-stopper for professional use. If no one is working on it, is there a guide to how to start on working with the Inkscape code, submitting patches etcetera? I'm not sure that I'll have much time to work on it but I am a programmer and I have worked with Linux fonts quite a lot over the years. I really like Inkscape and use it for design work (real, paid design work) quite a lot but it always hits a wall when a client is already using use a font which Inkscape can't handle but has to be incorporated, like Helvetica Black, which happened yesterday. There is almost nothing else which causes me to have to revert to Illustrator now other than font handling and I'm starting to really resent Illustrator because of it. Thomas Worthington

Skeletal Strokes (InkscapeLPE)
by unknown＠example.com 24 Jul '07

24 Jul '07

Hello all, Progress report of my GSoC: Skeletal strokes seems to work! (many thanks to the 2geom people!) See a screenshot here: http://wiki.inkscape.org/wiki/images/Lpe-skeletal.png and the wiki page here: http://wiki.inkscape.org/wiki/index.php/LivePathEffects I'd very much like people to test LivePathEffect things and report bugs on the wiki. Although one must know that the skeletal strokes effect is still under heavy development. Because I very much like my own branch and I'd like to keep it a little while longer, you need to checkout the live-path-effects branch to see this in action and test stuff, sorry! Cheers! Johan

feTurbulence - copyright status?
by Felipe Sanches 23 Jul '07

23 Jul '07

Reading the SVG specs, I see that there is a big chunk of C code in the feTurbulence filter effect spec. What is the copyright status of this piece of code? Is it public domain? After all, it is inside the specs, would them sue us if we copy&paste it? If we can use it let me know the conditions so that I can try to implement this filter more easily. the code is here: http://www.w3.org/TR/SVG11/filters.html#feTurbulence Juca

It may indeed be confusing sometimes, although also > useful IMHO. What do others think? I agree that the user should be in control of exactly which instance of a filter he is editing - he might have a blurred object that is then composited which he wants to again blur after the composite. There is no way you can code the dialog to determine what instance of the filter he intends to adjust. I'm not familiar with the current implementation, so please pardon my ignorance. However, I think it is necessary to have a list of filters on a pane of the dialog (much like the layers dialog) in order of implementation for the object/group which can easily be chosen for editing. They could then be named (?) and kept track of that way if so desired. It's a familiar method already, and seems to me the most intuitive way to control the filters. Of course, then you might even have some sort of indication (maybe an icon) of what filters are affecting the object, but which are applied to a different subset of objects (group), which could then be chosen and edited. It might be fairly complex, but something like this: choose the filter, a dialog asks if you want to switch the selection to the group affected by the filter (if it's different from the current selection). Make sense? It does to me, but I'm the one thinking it...

For my purposes, i.e. permanent effects on bitmaps, I think I should keep the format that the image is already in.

For image.jpeg, right now I'm creating a copied image at image_orig.jpg, unless image_orig.jpg is taken, at which point I ask the user for somewhere to save the new image, unless the image_orig.jpg which already exists is equivalent to image.jpeg. Back when I used Windows, that was how Picasa handled the issue, and I thought it would work for me too.

I don't know about speed issues -- but intuition tells me that having a 10 mb file would load more slowly than a 100 kb svg file and five 2 mb images. But that's a matter for someone who's put more time into Inkscape's rendering functions to answer. If I inserted an image and executed some special effect on it, and then found out my program had converted my image into base64 and embedded it into my svg document, without asking me, I wouldn't be too I happy, personally. I don't want to make that the only option, and I'd actually rather not have it default. My next goal is to be able to undo operations on linked images. If that isn't extraordinarily hard (and I don't expect it to be, I just have to get into the undo buffer, I guess), I don't see any reason why keeping images linked would be a bad idea. -Christopher

Convolve Matrix filter implemented
by Felipe Sanches 20 Jul '07

20 Jul '07

I have implemented the convolve matrix filter The patch and the 2 new files have been posted to the patch tracker: /src/display/nr-filter-convolve-matrix.cpp /src/display/nr-filter-convolve-matrix.h See http://sourceforge.net/tracker/index.php?func=detail&aid=1757228&group_id=9… The implementation isn't complete yet, but the basic is already working. For example, you can see that now inkscape renders correctly the 4th test in the SVG1.1 test suite. A screenshot is available at http://bighead.poli.usp.br/~juca/code/inkscape/inkscape-SVG1.1-testsuite-co… I am wondering what is causing the spurious horizontal or vertical lines when we scroll the screen. Any clue on that? Felipe "Juca" Sanches
