Video markup
by Александр Горбань 29 Dec '09

29 Dec '09

Hi, I'm thinking about creating tool to markup video (select areas containing objects, add tags) for my computer vision algorithms (head tracking, human detection and the like). The core functions of such tool: split video into separate frames, possibility to markup some object by drawing rectangles, circles or other closed contours objects on each frame, play markuped video, interpolate unmarked object coordinates between frames. It is seemed to me, that within inkscape it can be done in the following way: 1. Input extension that "convert" video frames into inkscape layers 2. Toolbar with play/stop buttons that toggle layer visibility to simulate video playback if you catch the idea, can you tell how difficult to implement the tool on inkscape basis? If it isn't very hard task what is the best way to do it: creating extension or creating patch? --- Best regards, Alexander Gorban

Wiki font
by Krzysztof Kosiński 29 Dec '09

29 Dec '09

Can someone change the Wiki font from 12px to at least 14px, and adjust other font sizes accordingly? The current size is really hard to read. I put this in Firebug, and it is much easier on the eyes: div.content { font-size: 14px; line-height: 1.3em; } pre { ... font-size: 12px; line-height: 1.2em; } And the title of the page should be displayed below the flag bar, in place of the big "Contents" heading. That would be enough to use the wiki comfortably. Regards, Krzysztof

Most people expect the image to stay in place. When you send an email attachment, it is not a magical link to the data on your computer. When you paste an image into a Word / ODT file, it is not a link to that file on your hard disk.

Drag and drop is currently not related to pasting, because drag and drop is implemented in src/interface.cpp, and pasting in src/ui/clipboard.cpp. They don't use the same code path. In fact the import code is simpler, because imported / dragged items are put into a group.

I think that "Publish" is a stupidity cloned from Corel Draw. Why should saving a PDF be completely different from saving any other file? Moreover the name is misleading: you are actually not 'publishing' anything in the sense of showing it to the outside world. You are only saving a file. A better name is "save standalone document" or something like this, but I don't see a difference between this and Export. Regards, Krzysztof

bzr - keeping the log linear
by Terry Brown 28 Dec '09

28 Dec '09

After the recent months worth of various people's commits becoming sub-revisions of one person's commits, I chatted on #bzr to see if there was a way to avoid this. Incidentally, the branch based workflow shown on the wiki will *cause* this problem, so I'll revise what's written there. Anyway, there is a bzr configuration flag which will prevent changes (other than extensions) to the log, i.e. it would refuse to accept the push which sidelines other people's commits. According to the #bzr people, this would set the flag on lp:inkscape python -c 'import bzrlib.branch as b; b.Branch.open("bzr+ssh://bazaar.launchpad.net/path/to/branch").set_append_revisions_only(True)' (if the user has the required permissions) They also pointed out the current sidelining could be undone, I might see that's involved, but not really sure if it's worth it, seeing there's no real damage. Cheers -Terry

Re: [Inkscape-devel] Specification: Improved image

On the issue of linking vs embedding images: can't we just have 2 commands? - Embed an image - Link an image Those who don't understand what Link an image means probably expect the first behaviour anyway. I'm among those who was surprised by the behaviour. I use Inkscape as an image editor first. Even if Inkscape is used to create svg files which were initially destined for webpage content, the difference is inconsistent treatment of similar objects (from casual user POV). For html, there are: - Images (external objects, must be attached separately) - Text (part of the html file) For svg, for the really clueless user, there are: - Graphics - More graphics (just with fewer editing options) This is perhaps a simplistic view, but what do most users know about the subtleties of image objects? There's a whole segment of users out there for which Inkscape is "to create images, like Photoshop, except Inkscape uses vectors, which is like manipulating lines and moving around shapes instead of adding blobs of paint."

bug 478157: Mid-markers are rendered above end-markers
by unknown＠example.com 28 Dec '09

28 Dec '09

Hi all, Who knows what determines the rendering order of the different markers? See https://bugs.edge.launchpad.net/inkscape/+bug/478157. Currently, endmarkers are drawn beneath midmarkers, although the code calls sp_marker_show_instance last for endmarkers. Perhaps this has to do with the 'key' that is passed to sp_marker_show_instance? (determines the layer?) Have a look at sp_shape_update_marker_view in sp-shape.cpp. Thanks, Johan

Just a small note on user cases: The lowest common denominator of Joe Schmoe out there (that can be expected to use Inkscape) is probably the Windows user who's only familiar with 2 programs: an internet browser and Microsoft Word. That's it. He's neither a webpage designer nor a raster graphics master. He's the type who (very regretfully) takes 2 MB photos, sends them as is to you by email, and doesn't even know (nor care) that he's doing it wrong (unfortunately, this is also about 90% of the people I've worked with...). Such a person's notion of copy/paste is: - Copy text. Paste in Word file. - Copy image. Paste in Word file. - If the image is modified, delete the original image and paste the new one in. - They don't expect anything they've pasted in to disappear when they move the file around or send it to their family/friends/boss. (and yes, that level of user may come to use Inkscape. I often use Inkscape to do charts for work, it's handy)

Node tool progress
by Krzysztof Kosiński 27 Dec '09

27 Dec '09

Hello everyone. Good news: there are only three regressions left in the new node tool now. 1. Sculpting (Alt+drag) doesn't work. 2. Snapping nodes doesn't work. 3. Transforming one handle using the keyboard (left/right Ctrl and Alt + various keys) doesn't work Everything else should work like in the old one. I think 1 and 3 are not critical, so the only thing left to fix before the tool is ready for prime time is snapping. Bad news: snapping is a complex feature, particularly because I want to provide it for nodeset transforms. Additionally, there is some code in SnapManager that assumes only one editable path. It could be finished before the new year, but it could as well take another month. Regards, Krzysztof

Passing data with sp_action_perform(SPAction *action, void * data)? [2]
by Alex Leone 25 Dec '09

25 Dec '09

Hello, (Sorry about the duplicate message - forgot to turn off rich text) I'm attempting to write a patch that adds a margin when setting page size through the "Fit page to selection" button in document properties. I've already added the ui elements (RegisteredScalarUnit's) for marginTop, marginLeft, etc, but I can't figure out how to get the values to the function that resizes the page. Here's how the page currently gets resized: 1. When clicked, "Fit page to selection" fires src/ui/widget/page-sizer.cpp: 487: PageSizer::fire_fit_canvas_to_selection_or_drawing() { Verb *verb = Verb::get( SP_VERB_FIT_CANVAS_TO_SELECTION_OR_DRAWING ); SPAction *action = verb->get_action(dt); sp_action_perform(action, NULL); } 2. sp_action_perform eventually calls src/verbs.cpp:2149: FitCanvasVerb::perform(SPAction *action, void *data, void */*pdata*/) { fit_canvas_to_selection_or_drawing(dt); } where the void *pdata parameter is the second argument from sp_action_perform. 3. This eventually calls src/document.cpp:601: SPDocument::fitToRect(Geom::Rect const &rect) My plan was to add marginTop, marginLeft, etc as parameters to SPDocument::fitToRect, and somehow pass these parameters through the void *data parameter in sp_action_perform. However, all the other calls to sp_action_perform in inkscape set the void *data parameter to NULL, and it looks like the action handler doesn't have any code to call free on the parameter after all the action listeners are serviced. Am I trying to do this completely wrong? Thanks, - Alex (Attached is a patch that adds the margin UI elements in document properties)
