Re: [Inkscape-devel] clip/mask edit
by Guillermo Espertino 02 Mar '08

I really needed this feature. Good work! A couple of thoughts about clipping paths and masks. -Clipping should be also placed in the right-click menu on the canvas. It's a tool used very frequently and since it hasn't a keyboard shortcut (please correct me if I'm wrong) it's kind of "hidden". A more accesible place would be welcome. -Clipping path and mask nodes should be considered in snapping. Currently they aren't and it's very difficult to manually place clipped objects in a specific place when snapping is needed. -Finally, I agree with the idea to make the clip and mask editable directly from the path edit tool. It would be fast and intuitive. What do you guys think? If you agree with these ideas I'll fill the proper bug or RFE.

Strings to translate in bitmap effects.
by Marcin Floryan 01 Mar '08

01 Mar '08

Hi! I was trying to review bitmap effects and found two where translation is not used properly. In /src/extension/internal/bitmap there are two files: addNoise.cpp and channel.cpp where strings are properly marked for translation (and thus are in the .po files) but do not appear to be used. I thought it would be nice to fix this for 0.46 since the strings are already there but I can't trace where the XML is used to create the UI. It seems like the items for Combo Box are not being created with a call to gettext. This could potentially benefit more then just those two effects and would also allow for the combox box items in the idx files to be translatable.

Windows Dev Build Feb 26 08 - improvements and problems...
by rygle 01 Mar '08

01 Mar '08

Hi, Just writing with some experiences of the latest Dev build for windows. 1. It seems to be rendering a bit faster lately. Probably due to Bob's hard work with dll's and the latest Cairo. Thanks! 2. PDF output seems to be doing gradients and transparency quite well (as vector art not raster), which is great :-D, but still not blurs :-((. Again probably due to Cairo improvements. Getting close! 3. The windows dialogues have kicked in I notice. Trying to view a thumbnail causes a crash on my system. I also miss the GTK ability to store your own folder shortcuts on the side. Have to find some windows program to do that! 4. With the windows dialogues (or perhaps related to Alexandre's changes - see http://www.nabble.com/Regarding-WMF%2C-PS-based-AI%2C-SK-and-FIG-files-supp… here ) the saving sequence seems to be messed up. 4a. If I select save as PDF via Cairo, it goes for the selection immediately below, which is PS. If I select EMF, it saves it as POV. Whatever I want, I have to go for the one above, but you can't now re-select Inkscape SVG. Always one step below, unless I just hit save, which does whatever was last without problem. 4b There's a weird loop going on when saving, which I think is related to the bug above. See my comment at step 4 below. 1. Save something as an Inkscape SVG (default). 2. Save as PDF or whatever else. 3. Save again as Inkscape SVG and try to close Inkscape. 4. Inkscape complains 'The file "{filename.svg}" was saved in a format that may cause data loss! Do you want to save the file as an Inkscape SVG?' options - Close Without Saving, Cancel, Save as SVG. (I think this is caused because now when you select Save As -> Inkscape SVG, you're actually choosing Plain SVG (the one below), which Inkscape thinks will cause data loss). 5. Click ' Save as SVG' 6. Back to step 3 and infinite loop - must select 'Close Without Saving' to escape the loop. Obviously some good steps forward have been made, but a few minor problems have crept in. I hope this is helpful.

I've added the first cut of extending tablet support to switch tool based on input device being used. If anyone has a tablet and could give it a spin that would help.

How to mark bugs for 0.46.x in LaunchPad?
by Maximilian Albert 29 Feb '08

29 Feb '08

Hi, sorry for this seemingly stupid question, but how can I mark a bug as also affecting 0.46.x so that it can be picked up by Bryce or Josh and copied over to the release branch? Neither of "Also affects another project/package" seems to work. :( Thanks for any hints, Max

Dev opinions needed: when to activate SPDesktops?
by Maximilian Albert 29 Feb '08

29 Feb '08

Hi all, during my investigation for the cause of bug #195373 [Creating a new document breaks a 3D box] I have found that when a new desktop is created, it isn't automatically set active right away. Namely, in sp_desktop_widget_new() the function inkscape_add_desktop() is called, but in this function the new desktop is *appended* (instead of *prepended*) to the list of existing desktops. Thus the following 'if' construct if (DESKTOP_IS_ACTIVE (desktop)) { ... } is not triggered (except for the very first desktop). I wonder if this is intentional. Well, it probably is, but why? :) Is there any reason why new desktops shouldn't be activated upon creation? The current behaviour is what's causing bug #195373 since the perspectives in the _old_ desktop/document are updated according to the toggle states of toolbar buttons in the _new_ desktop. There might be other ways to fix this but the easiest I have found is to simply change g_slist_append (inkscape->desktops, desktop); to g_slist_prepend (inkscape->desktops, desktop); in line 891 of inkscape.cpp. However, this would render the above-mentioned 'if' construct obsolete and I guess that there was a reason for introducing it in the first place. But since inkscape_add_desktop is not called from any other place except sp_desktop_widget_new() it looks like a rather safe thing to do. I committed this change to SVN in rev. #17510. Please tell me if there are any objections or concerns that this could break other things. I will then revert it and try to find a different fix. Otherwise this should go into 0.46 as well (I'll file a bug in LaunchPad as soon as I know that it's safe to do). Thanks, Max

Regarding README
by Alexandre Prokoudine 29 Feb '08

29 Feb '08

Hi, Could somebody with a real extensions mojo please review "Extension Dependencies" section of README file in the root directory of sources? It looks kind of outdated. P.S. man page says: "...(C) 1999–2007..." Cheers, Alexandre

minor items in LPE stuff
by Jon A. Cruz 29 Feb '08

29 Feb '08

I've seen these three warnings: live_effects/lpeobject.cpp: In member function 'LivePathEffectObject* LivePathEffectObject::fork_private_if_necessary(int)': live_effects/lpeobject.cpp:261: warning: comparison between signed and unsigned integer expressions live_effects/lpe-curvestitch.cpp: In member function 'virtual std::vector<Geom::Path, std::allocator<Geom::Path> >Inkscape::LivePathEffect::LPECurveStitch::doEffect_path (std::vector<Geom::Path, std::allocator<Geom::Path> >&)': live_effects/lpe-curvestitch.cpp:92: warning: comparison between signed and unsigned integer expressions live_effects/lpe-curvestitch.cpp:93: warning: comparison between signed and unsigned integer expressions I think the first one is minor, and the second pair just need a change from 'int' to 'gsize', but I'm not sure what it might do to calculations inside the loops. If anyone who knows those parts could give it a quick look, that would help. Thanks.

Regarding WMF, PS-based AI, SK and FIG files support
by Alexandre Prokoudine 29 Feb '08

29 Feb '08

Hi, During last weekend I played with UniConvertor and found out that: 1) Its support for WMF is better than the one of wmf2svg simply because objects are editable at once. You can also have a look at feature support tables at [1] and [2]. 2) Old PS-based Adobe Illustrator files look pretty cool, though the ones created with Freehand still don't open correctly. What doesn't work is importing text when fonts in use are absent. UC just drops such text objects. I'm talking to Igor about fixing it. We can have this by just replacing the converter call to cdr2svg.sh which is already written in a universal way. This implies no strings changes at all. If we look a little further, we can ditch the Sketch/Skencil dependency (skconvert, actually) for opening .sk files (UniConverter actually used to be part of Sketch not so long time ago, thus it's same as skonvert in this case). Same probably applies to XFig dependency (fig2dev utility) for opening .fig files, but the very few XFig 3.2 files I had around didn't work at all with UC. I'm talking to Igor about fixing this as well. What is beautiful about this approach is that we will have all these things for free on _all_ platforms, since we are shipping UniConvertor for both Linux, Mac and Windows in 0.46. Here is my proposal: 1. Rename cdr2svg.sh to uniconv2svg.sh 2. Fix ai_input.inx, cdr2svg.inx, sk_input.inx and wmf_input.inx to use it. Probably fig_input.inx too, if a bugfix UC release is out before we package 0.46. Is this acceptable during Hard Freeze? Later we could also add extensions to support CDT (CorelDRAW templates), CCX (Corel Compressed Exchange), CMX (Corel Presentation Exchange), CGM (Computer Graphics Metafile), AFF (Micrografix Draw) and SK1 files the very same way (I've already written .inx files). But this implies strings changes. Thus either 0.46.1 or 0.47. [1] http://www.sk1project.org/modules.php?name=Report&page=08 [2] http://www.sk1project.org/modules.php?name=Report&page=06 Alexandre
