win32 build working again
by Bob Jamison 08 Apr '24

08 Apr '24

The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

Also, the pixel dimensions of the two methods differ, if the graphic bleeds over the edge of the 'page'). Can someone tell me why we have a non-vector format in the save as list? One that seems redundant and apparently with less functionality than the normal export. Is this for testing purposes?

NEW: mouseover cursors in Selector
by bulia byak 28 Oct '10

28 Oct '10

Selector tool has a new mouse cursor (arrow with an open hand) for when your mouse is over a selectable object, and another (arrow with clinched hand) for when you're dragging an object. This improves precision of selection and UI consistency (previously, the mouse cursor over a selectable object was different across platforms, e.g. hand icon on Linux or four-way arrow on Windows). -- bulia byak Inkscape.

Status of dbus awareness
by Kent Tenney 26 Sep '10

26 Sep '10

Howdy, I just built the inkscape trunk from bzr and ran this script #!/usr/bin/python import dbus bus = dbus.SessionBus() inkdoc1 = bus.get_object('org.inkscape', '/org/inkscape/desktop_0') doc1 = dbus.Interface(inkdoc1, dbus_interface="org.inkscape.document") im = doc1.image(100 ,100, '/home/ktenney/Firefox_wallpaper.png') Which worked on a dbus branch a while back. Now it starts inkscape, but does not place the image - was the dbus code merged? - if so, how do I enable/use it? - if not, where is dbus capable code? Thanks, Kent

gradient mesh
by sid datta 17 May '10

17 May '10

Hi, Are we still waiting for the SVG standards before we can implement gradient meshes ? I have a ( pretty simple and obvious ) method of rendering gradient meshes that is simpler than blurring multiple beziergons and is quite fast ( 100 ms in Java rendering 500x500px approx ), I was wondering if we start putting a basic gradient mesh in inkscape and we can conform/export to the SVG format when it comes out. I believe we are trying to get a triangle gradient primitive approved from SVG. Do we have any plans of getting a quadrilateral primitive ? It will be more accurate for gradient mesh. This paper I found explains some quadrilateral rendering techniques : http://vcg.isti.cnr.it/publications/papers/quadrendering.pdf Thanks -Sid

node tool testing
by bulia byak 22 Apr '10

22 Apr '10

Krzysztof, I finally found time to test the new node tool. Overall it feels great, but of course I found many small and not so small things to fix :) #1 is my personal pet peeve, if you can't see it please just give me pointers to the code which passes events up and I'll have a look myself. I'll probably have more as I do more testing, but here's the fist batch: 1. Bug: Middle-button dragging and Shift-middle button zoom rubberband still do not work. Are you using a mouse with a middle button to test? They work in Selector but not in Node. 2. Lost feature: when rotating/scaling nodes by keys and one node is mouseovered, it is used as center of rotation and scaling. 3. Lost feature: when ctrl+alt+dragging a node, it should slide along the handles _and their perpendiculars_. 4. Lost feature: when ctrl+alt+dragging a node, and it has a linear segment on one side, it should slide along the continuation of that segment. 5. Lost feature: node sculpting. Will you work on it, or do you want me to work on porting it? 6. Bug: select a single node and rotate it by [] with or without Alt: it rotates around some random center far away, instead of around itself. 7. Lost feature: When rotating a handle with Ctrl, it now snaps to the original position and 15 deg increments from that original position. The previous behaviour was: snap to origin, its opposite and perpendicular, to vertical/horizontal, and to 15 deg steps from vertical. This is much more useful because more often, I use Ctrl to snap it to vertical or some simple angle like 60 deg. 8. Lost feature: create a cusp node next to a linear segment; press Shift+S; it becomes semismooth, aligned with the segment (correct); now press Shift+S again; old behavior is to make it fully smooth, extending the second handle, but your tool does nothing. 9. Lost feature: Rotating a handle with Shift before allowed to rotate the second handle by the same angle, thus rotating a cusp node as a whole; now it does nothing. 10. Suggested feature: now that we can edit multiple paths, Ctrl+A when nothing selected should do the same in Node tool as in Selector, instead of doing nothing as now. 11. Performance: Create a path with thousands of nodes (paste text, convert to path, combine), select it in Node tool: notice how slow it all becomes, freezing for many seconds, as you simply move your mouse over the path. My guess is that it calculates something on each motion event and does not cache the results. The old tool also wasn't very snappy in such situation but it was much better, only freezing for a couple seconds at most with the same file (test it!) partly because it cached the livarot representation of the path it used for proximity/over the path calculations. 12. Lost feature: the statusbar used to say how much total nodes are there ("2 of 5 nodes selected") and, for a single node, its type (smooth, cusp, auto). For multiple subpaths it said e.g. "2 of 9 nodes selected in 2 of 3 subpaths". Now it only says "Selected 2 nodes" (which is also a wrong word order, suggesting an action instead of a state). Could you please just copy this part from the old node tool? 13. Suggested feature: now that we can select multiple objects, the statusbar hints must reflect that, in the same way as subpaths, e.g. "2 of 9 nodes selected in 2 of 3 subpaths in 1 of 2 selected paths", or simply "2 of 9 nodes selected in 1 of 2 selected paths" if there are no subpaths involved. 14. Bug: when dragging a node handle, statusbar erroneously says "Move by" instead of "Node handle:" as did the old tool. 15. When mouseovering a node, it says "click to select" even if it is already selected. I'd like to copy this from the old tool as well, which suggested various modifiers for dragging instead. 16. On the node deletion discussion, I found the current behavior satisfactory: if you Del, you get curved approximation; if you Ctrl+del you get linear segment from linears. I think this is logical (unless I miss something). 17. UI suggestion: since the show/hide seltrans handles button belongs to visualization, it should be moved to the right end of the controls bar, next to node handles and node outline toggles. 18. Crash: draw a path; draw a path and apply it as mask; draw another and apply as clippath; go to node tool; enable both mask and clippath editing; drag a mask node; drag a clippath node; drag a node of the path itself; undo 4 times - crash. 19. UI bug: create with Pen a Spiro path; now switch to Node tool - the green outline of the source path is visible always, even when "show outline of path" toggle is off and "show path parameter" was never pressed. Also, as we discussed in the summer, I suggested a purple color for LPE parameter paths, so they are not confused with clippaths. 20. Crash (somewhat hard to reproduce): With Pencil in Spiro mode, create a path with just two nodes (click, click). Now create a curved doodle path (unrelated bug in Pencil: you need to deselect first path before drawing second, otherwise they will become joined!). Now select both paths, go to Node. Select the end node of the linear path and start node of the curved path. Mouseover the latter and press Shift+J. Then press Ctrl+Z while still mouseovering the joined node. Crash: Program received signal SIGSEGV, Segmentation fault.

Mac OS X: osx-dmg.sh - osascript: dmg_set_style.scpt
by Wolf Drechsel 08 Apr '10

08 Apr '10

Hello everybody, I tried to dmg inkscape 047 X11 - but ended up with an image, which contains a link to /Applications and a folder called "Contents" - which seems not to be a .app bundle. When running the osx-dmg.sh, I get the message: osascript: dmg_set_style.scpt: No such file or directory In fact, the dmg_set_style.scpt cannot be found on my machine, it looks as if it were contained by earlier source packages and dropped recently. Could somebody be so kind and mail me the script - or - in the case - guide me to another solution of that problem. Yours, Wolf

Adaptable UI problems
by Krzysztof Kosiński 03 Apr '10

03 Apr '10

I have some doubts about the adaptable UI feature. Part 1: UI issues - The UI mode selection combo box (called "Task" for some reason) has usability problems: 1. it jumps around when changing mode, so every time I change it, I have to find it again to try another mode; 2. when the main commands toolbar is vertical, it causes a very large horizontal padding on it, even when it's hidden in the overflow menu. - Tearing off toolbars does not adjust their size to fit the controls. If I tear off a toolbar from a small window, I get a toolbar with an overflow menu. If I tear off from a maximized window, I get a toolbar with lots of unused space. This makes tearing off highly useless. - Toolbars can be torn off but can't be attached in a location different that the original one. This is because they use GtkHandleBox, for which the docking position is fixed. At the same time GDL has a widget named GdlDockBar which sounds like a true dockable toolbar (but it might as well be something else, I don't know). Part 2: UxManager class - UxManager::setTask: Magic constants in switch. - UxManager constructor: "tags" is created but doesn't do anything. - What is the point of having several desktops attached to one UxManager? Part 3: util/ege-tags.h, util/ege-tags.cpp - ege-tags.h: It supposedly implements http://create.freedesktop.org/wiki/ResourceTagging but at present I don't see any place in Inkscape that could make use of tagging. - Even if the aforementioned specification was good, the UxManager class apparently tries to do two completely unrelated things: manage external resources and change the UI mode. - TagSet: if I understand correctly what this class attempts to do, it should use std::tr1::unordered_map<Tag, int> with appropriate hash and equality predicates instead of the combination of std::vector<Tag> and std::map<std::string, int>. Part 4: other problems - toolbox.cpp:1578: code related to changing the UI layout uses a switch to assign function pointers. Polymorphism should be used instead. Regards, Krzysztof

Inkscape 0.48 Chill (the winter is heavy everywhere!)
by Joshua A. Andler 18 Mar '10

18 Mar '10

Hey all, This is where 0.48 as a "release" begins! This email will be a little redundant for developers, but will let users know what the current plan is. The next stage (Frost) kicks into gear at the beginning of March in case you were wondering. For right now: *New feature development will focus on wrapping up. *We will identify "make check" issues (we need to make sure things are "friendly" for packaging). *We will run an About Screen contest on DeviantART (which I will announce within the next 24 hours and post all info to both lists). *Ensure that the Release Notes are at First Draft stage. This is primarily a developer task, however, if you are a user and follow development closely and have something to contribute in this area which we may have overlooked, such as fixed bugs, changes in functionality, etc. please contribute. *Update tutorials and other docs (we could use volunteers). Not joking, if you are an Inkscape user and have the misconception that the only way you can contribute is by code, you are missing out on one of the most important things for our users... documentation. If you have time to spare and some tips for others that you're willing to share, please let us know. --- boring developer junk --- I do want to request from developers... most "big" new stuff be committed by March 1st if possible (or shortly thereafter). JonCruz: The swatch previews for "auto" swatches are starting to worry me given that they have not been working for quite a while now (since 0.47 dev cycle). The same goes for the method of editing color (gradient editor rather than F&S dialog). If you will not have time to address these before Freeze, please expect that I will request the feature is disabled again for this release at that time... I will also request that in 0.49 that you not re-enable it until you are looking to actively work on it. Krzysztof: The new Node Tool is fantastic. I know you're actively working on it, but I do just want to make sure that you will be able to set aside a few hours here and there for bugfixing as there are still a number of bugs and features missing from previous releases. Arcadie/Michael: The Connector Tool really is not consistent with the behavior of other tools. If it is not likely to be sorted out by Freeze, I will request that at least the tool controls button for "add connection point" be disabled, as it is not user friendly at this point. Please know that I am not targeting people or criticizing their work. This is a schedule issue and our date of release was horribly far behind schedule for the past couple releases. We will just be sticking to release schedules much more strictly than we have previously, and if features aren't "bug-free"/complete enough to release on time... there's always next release! :) Besides, we're going to be in the trenches w/ 0.49 for a bit by what has been discussed so far. Cheers, Josh
