bug with moving selections
by John Cliff 13 Feb '04

13 Feb '04

Hi folks, Found a bug that seems a bit weird, If you create a shape, doesnt matter what, go to select and drag it, but move the mouse outside of the drawing area, it becomes impossible to interact with the interface again until you do another select action. Ie if you try to change tool, use a menu, close the program etc, it behaves like its hung. If the shape is the only thing you've got in the document the only way to get control back is to click on it again, made me think the whole thing had died for a minute there. Have only tried it on Win 2k, but it does it in both the builds I've got on my home box, and the 2 on my work one. cheers John btw isnt bug 894662 closed? __________________________________ Do you Yahoo!?

That seems to be http://sourceforge.net/tracker/index.php?func=detail&aid=852976&group_id=93… Obviously the reason is that on Windows, GTK sends different (or no) events when mouse is outside the window. This needs investigation, unfortunately we have only one developer actively working on the Windows version. >btw isnt bug 894662 closed? I guess it waits for confirmation. If you can confirm that you can import PNG, GIF, JPEG with the latest win32 build, I'll close it. _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

PROPOSAL: Reorganizing Directories
by Bryce Harrington 13 Feb '04

13 Feb '04

I'd like to propose some structural changes to both the codebase directory hierarchy and the directories created during installation. If these changes are acceptable, they could be introduced for the 0.38 development cycle. Bryce Distribution / Packaging Files ============================== Presently, we have a number of files in the codebase related to generation of distribution packages. Some of these files are in the root inkscape/ directory, others are in subdirs like inkscape/debian/. To head off potential clutter as Inkscape becomes supported on a wider variety of systems, we should collect as many of these packaging files as feasible into a subdir called inkscape/packaging/. Inside that directory would be distro-specific subdirs, plus a common directory for shared scripts and collateral: inkscape/packaging/ common/ debian/ fedora/ fink/ mandrake/ suse/ Config Files ============ Currently we do not have global config files, but instead put the config file in the user's home dir in ~/.inkscape/. These are generated at run-time by Inkscape itself, so the defaults are hard-coded into the application, and can't be customized by the sysadmin except by editing the appropriate header file and recompiling/repackaging the app. The correct approach for Linux apps is to have both user and global configs, and to use the global as the default if the user does not yet have a config file. This way, site customizations are known (such as the fact that its shared files are in /usr/share, vs. /usr/local/share, vs. /opt/inkscape/share, etc.) The proposal is for Inkscape to establish its config file location in /etc/inkscape/, and to place a global preferences.xml file there, as well as any other config files we need later, like extensions.xml, etc. Ideally, the global config file would be loaded first, and then the user config file "override" any portion of the global options. This way the user config file only needs to contain customizations, so that if we choose to change the defaults in a future install, the user's config files do not necessarily become invalid. Inside the CVS codebase, the default etc. files would be stored in inkscape/etc/, instead of being produced by the application at runtime. During installation, installation-specific parameters (such as alternate paths for various files) will be substituted in appropriately. "Share" Collateral ================== Inkscape currently generates a /usr/local/share/inkscape/ directory during install, and copies the contents of the codebase's icons/ directory to that location. We need more pieces of collateral installed, and need to do so in a more organized manner. The recommendation is to establish a set of subdirs in /usr/local/share/inkscape/, as follows: AUTHORS NEWS clipart/ examples/ extensions/ fonts/ gradients/ icons/ keyboards/ markers/ palettes/ patterns/ screens/ about.svg templates/ tutorials/ This uses a flat hierarchy for the sake of simplicity. In the CVS codebase, all of these would be placed in inkscape/share/. This way, the installation script could be set up to recursively copy everything in that directory to the target share directory, and we won't need to specify each of the subdirs in that script, which will make maintenance less hassle. For clipart, I think we definitely want to consider being able to tie in with "external" clipart collections. One way would be to simply put symlinks in the clipart dir to those collections. This way, if the flags package were to install into /usr/share/flags-svg/, we'd just symlink there. Possibly similarly for extensions. I think an argument could be made that the tutorials ought to be placed somewhere under the /usr/doc/ or /usr/local/doc/ path, so I'm not 100% certain of having the tutorials located here.

openoffice fileformat
by Johan Ceuppens 13 Feb '04

13 Feb '04

Hi, I've tested libinkjar and it can read openoffice fileformats now. I'd like to know if I can hook this up and move it to cvs HEAD. I was thinking of bringing up a GUI which greps/seeks the jar file for filenames and letting the user choose which SVGs to open. If you'd like different or additional behaviour, please share with the list. Johan

Formatting code
by Bob Jamison 13 Feb '04

13 Feb '04

Re: our conversation on Jabber about formatting data for the repr tree, here is some code I appropriated from Apache's APR lib, which can give us total control over formatting output strings. With Mental and Bryce's work in this area, these files might not be necessary, but then again they might be useful, so here they are. One very nice function for the repr tree would be: sp_repr_printf(repr, key, "format", args...) Would relieve the need for a lot of temporary buffers all over the place.

Jon, I do not mean restore the old system picker, but to add HSV fields to your new picker, right above the alpha spinbutton. _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

Thanks for the feedback! > First, if I've got a new session of inkscape, and i >do file>open, why does it open it into a new window >rather than the blank one I've got in front of me? >every time it does it it strikes me as odd. Yes, it's in the plans. Maybe next version. > Second up, have you considered making use of the >boolean ops to add paintbrush/eraser tools ala flash? >the functionality is all there just spread across >several tools currently. The way I've been simulating >it currently is to use the calligraphy tool to 'paint' >an area, then whenever you paint additional >areas immediately switch to select and ctrl++ it to >the last section. Not sure about usefulness of this. The vector approach is to keep things separate and at a high level of abstraction for as long as possible, and only merge/flatten/convert to paths as the last stage if possible. So if I need this functionality, I would actually prefer to have shapes separate to I can move and adjust them, and do a union or difference on them if necessary (but I think in many cases, just grouping them together would be convenient enough). On the other hand, what you propose may be simple enough to implement, but we need to do a paint tool with user-definable strokes first, otherwise the booleans are of little use IMHO. > Another feature that I'd love to see would be >variable offsets, ie a dynamic offset with >node weighting allowing the offset to be modified at >each node so I could generate a line of varying >thickness (like the calligraphy tool) but still >editable by the basic centreline path. This would be a >godsend for doing comic style drawings where the line >weight is important. I know that ones a big task, just >putting the idea out there. Yes, useful, but perhaps more uesful in the short term and easier to implement is a variable-width stroke with some predefined shapes. I think our developers had some prototypes of this. > With regards to the 0.37 release, the builds i >downloaded from Bobs site (which is really useful, >both for builds and build instructions, cheers Bob) >seemed to have problems with the keyboard shortcuts >being messed up, the dialog ones were all muddled, >(for instance Ctrl+Shift+M was opening fill/stroke) >just checked the latest one there and its still the >case.(zip file Inkscape0402120319.zip) Very strange. Anyone else experiencing this? >What happened in the Fill/stroke dialog? the entry >boxs for RGB values on the wheel tab are gone That's temporary, we plan to restore them, although not RGB - the wheel is HSV and it will have HSV fields, if you need RGB switch to the RGB sliders. >as is >the dropper icon, both of which were really useful. Dropper on the dialog is redundant, you can use the dropper tool >(its a pain having to switch tool to do a dropper >action, What's the problem with the dropper? We discussed moving the dropper to the dialog and removing the tool, but then decided that the dropper will be very useful without the dialog, when we have a current color indicator and a palette. >btw, anyone got any suggestions as to the best place >to get started with getting familiar with the code? Read developer's howtos on Wiki - there's quite a lot of info there, although it's unorganized. Then look into the code and try to find what seems easiest - I don't know what it may be for you :) I started with adding new keyboard shortcuts, that was easy and fun, and gradually learned many parts of the codebase from there. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
