NEW: truncated text indication
by bulia byak 23 Dec '09

23 Dec '09

When a flowed text is truncated (i.e. the frame is too small for the entire text), the frame is shown red, and the statusbar hint includes [truncated]. You need to resize the frame to see the truncated end of the text. Analogously, if the path of a text-on-path object is too short to display the entire text, the statusbar will report it as [truncated]. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

why two addresses for Release Notes?
by Alvin Penner 23 Dec '09

23 Dec '09

there are two addresses for release notes for 0.48, and they do not appear to be equivalent, was this deliberate or accidental? http://wiki.inkscape.org/wiki/index.php/Release_notes/0.48 http://wiki.inkscape.org/wiki/index.php/Release_Notes/0.48 -- View this message in context: http://old.nabble.com/why-two-addresses-for-Release-Notes--tp26902465p26902… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Spay tool UI
by Pierre-Antoine MARC 22 Dec '09

Hi there I am currently filling the release notes for the spray, so it may help to use it... To answer Bulia's questions (thanks for feeding back by the way !) : - Mean and SD are the parameters of the gaussian function here. We did not call them otherwise... The "mean" parameter sets the center of the gaussian. If it is set to 0, then it will be the center of the cursor. If you increase the value, the spraying will look more like a circle... The SD sets the width of the gaussian. It is not that techy if you know what a gaussian is. - Population is more like a probability parameter. As it is written in the code, if it is set to 50%, then the item has 50% chance to appear... If anyone has an idea to improve it, please do ! We did not spend much time to think of it. - I don't think the Spray options are that bad. We did not want to overload the toolbar with options, so it seemed natural to us to make it that way. Again, hope the notes will help ! Cheers, Pierre-Antoine

Need to work in color spaces other than RGB
by Jon Cruz 22 Dec '09

22 Dec '09

I think we've hit the point where we need to revisit our rendering and such to include more than just RGB. This bug is one example: "Export to TIFF to support CMYKA color" https://bugs.launchpad.net/inkscape/+bug/492402 It looks like to be able to solve this case, we would need to be able to have our engine render to four-channel CMYK in order to preserve data. Simply rendering to RGB and then converting to CMYK using LittleCMS won't work, since black ink separation will be lost, etc. Am I seeing this wrong? Also, could we perhaps get away with export by rendering n channels, each being grayscale? Thanks.

Step-by-step debugging with Code::Blocks
by Yann Papouin 22 Dec '09

22 Dec '09

Hi, As a Delphi developer I'm used to debug my apps in a step by step way. I worked with Code::Blocks 2 years ago in a student project and I found it really easy to use. Today I'm using it to understand how Inkscape works and what methods are related to a specific work. [image: usshot-148.png] I'm posting here the Code::Blocks project that I'm using (it must be put in the "inkscape/src" directory): http://ftpmerou.free.fr/inkscape/codeblocks/Inkscape.cbp The nightly (monstly?) build of Code::Blocks can be found here: http://forums.codeblocks.org/index.php/board,20.0.html Note that it's no a replacement of the btool, you steel need it to create the config.h, the dist directory, and targets not included in the CB project (inkview, cxxtest, ...). Note that if a file is added/removed from the repository, you will have to add/remove it yourself from the CB project or wait for an updated project version. Note that the config.h needs to be moved the "inkscape/src" directory too. http://ftpmerou.free.fr/inkscape/codeblocks/config.h If btool is working fine, you should not have any problem to build targets as paths are still the same but: C:\devlibs can be changed in "Build Options" [image: usshot-145.png] c:\mingw can be changed in "Settings" - > "Compiler and debuggers..." [image: usshot-146.png] Finally, there is still one thing that I don't know how to realize in CB, so you may need to set a global var in your OS for pkg-config: [image: usshot-147.png] And now you are ready, after building LIB target and EXE target, to start debugging the EXE target by pressing F8.

Mac OS X: Shift- mouse wheel (scroll right/left) doesnt work
by Wolf Drechsel 20 Dec '09

20 Dec '09

Hi everybody, up to now every inkscape version I tried on my Mac OS X 10.4.11 PPC had this annoyance: Scrolling up and down by mouse wheel works nice - zooming by ctrl - mouse wheel as well - but scrolling vertically (right-left) by shift - mouse wheel doesnt work. Is that a question of preferences - or does anybody know how to solve it? Greetings, Wolf

For example, jitter nodes on a 4 node closed > shape (use a large jitter) will create a shape with 6 nodes, with the > last 2 open (attached) You are correct. cubicsuperpath.py does not maintain the open/closed property of paths. I wouldn't say that it is broken because it has always been this way. It makes other changes to the path data too; it converts all segments to one or more cubic bezier segments. Its just not as good for round tripping path data as simplepath. > This is on windows in inkscape .47 release. This is not platform or version specific. So what can you do? Well, I haven't thought through this yet. But maybe you could make csp's inner lists a special list subclass that has a property for the closedness. Or maybe you could add an optional parameter to formatPath (or a new function, if that is better API) that closes the path if the first and last points are coincident. Aaron Spike

spray tool question
by Alexandre Prokoudine 18 Dec '09

Hi, How does "Spray objects in a single path" option actually work? Maybe the students could fill the ReleaseNotes048 page with description? :) Alexandre
