Clipping & EPS export
by Arnout Standaert 17 Nov '06

17 Nov '06

Hi list, I'm using clipping in some of my graphics and just noticed that the clipping gets lost in the EPS export. In other words, the EPS shows the full clipped object instead of only the unclipped part. This corresponds to bug 1537281 as far as I can see... is there a quick fix for this? Thanks a bunch for any useful tips, Arnout

Install miseries.
by John R. Culleton 17 Nov '06

I have a Slackware Linux system, at this point release 11. Slackware does not include Gnome. when I attempt to compile Inkscape I get a long list of missing packages. When I attempt to install the precompiled version using: inkscape-0.44.1.x86.WONKY.package things get even worse. Fontconf gets messed up and I have to reinstall Slackware 11 from scratch to straighten things out. Which distro of Linux is Inkscape friendly? I can set it up on a separate partition. -- John Culleton Able Indexing and Typesetting Precision typesetting (tm) at reasonable cost. Satisfaction guaranteed. http://wexfordpress.com

NEW: color effects extensions
by bulia byak 16 Nov '06

16 Nov '06

Contributed by Jos Hirth, with some changes by me: * Color effects: a new group of extensions in the Color submenu of the Effects menu allows you to adjust all colors of a selection at once. These commands affect both fill and stroke colors, including gradients (but not bitmaps). The commands include Brighter and Darker (adjust brightness by up or down by 10%), Desaturate, Grayscale, Negative, commands for removing or swapping the Red, Green, Blue channels, as well as a Custom command where you can set your own formulas for modifying the color channels. These extensions are a temporary solution; in a future version, similar functionality will be added to Inkscape core. Adjusting gradient colors may be buggy because a gradient is sometimes shared by more than one object. Also, undoing color changes on gradients exposes a bug where an object seems to "disappear"; this is however only a display issue (probably caused by the order in which gradients and their users are restored on undo) not causing any loss of information. Finally, on large documents and large selections with gradients, Python's XPath code may get quite slow. Despite these shortcomings, I decided to commit this, because it's genuinely useful functionality which was so far missing in Inkscape. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Extension Documentation
by Aaron Spike 16 Nov '06

16 Nov '06

People have been noticing the sad state of Extension System documentation frequently. I think we should change this. I've started reorganizing things on the wiki. I've taken an old mail from Ted and pasted it at: http://wiki.inkscape.org/wiki/index.php/ExtensionArchitecture Never seen a clearer description! http://wiki.inkscape.org/wiki/index.php/ScriptingHOWTO describes in general terms what is needed to write a script/program in any language that communicates with inkscape as a Script extension. http://wiki.inkscape.org/wiki/index.php/MakingAnINX will be home to a description of the INX format. Ted or anybody else do you have the INX DTD that I had worked up way back when? I can't seem to find it. The last step will be to create a page describing the helper modules for extension writers who choose to use python. :-) It is just a start, but I hope we can clear things up and reduce the barriers for contribution. Comments? Aaron Spike

Help Wanted: Autopackager
by Aaron Spike 16 Nov '06

16 Nov '06

I took over maintaining the Inkscape Autopackages both to relieve Mike Hearn, who was not an Inkscape developer, and to increase my knowledge in how applications are compiled and packaged on linux. Since then my free time has diminished and my interests have shifted. So I'm looking for an interested group or individual to assume this responsibility. Some knowledge of compiling applications on linux or a strong desire to learn recommended. :-) Anyone? Aaron Spike

I generally copy-paste-in-place and then delete unnecessary nodes that leave me only with the piece that is most curious to my cause. I am familiar with "Break Apart" function, yet it only works for objects which contain multiple disjoint paths. Would be rather nice if I could select necessary points of the path and "extract" them into a new object without using "Cut Path," since it requires another shape to place correctly... -ilya.

Automating Inkscape
by ilya y. rostovtsev 15 Nov '06

15 Nov '06

Hello: I've been working on a number of things in Inkscape, a lot of which deal with tracing of many frames of 2D animation. Since I generally apply the same settings to a multitude of files, I was wondering if there is a way to do command-line access of "Trace Bitmap" command that could still utilize my settings... I only ask because most characters are extremely low-res to begin with and require being cut into a number of parts to create a good final composite. If there was a way to convert large amounts of bitmap data to SVG based on a specific setting I've set, and perhaps a way to cleverly automate coloring of the parts as well (if I can trace, I can figure out the rest), I could save a monumental amount of time. Any information is greatly appreciated. -ilya.
