GUI For Insckape Script Extensions
by Redefined Horizons 05 Oct '07

05 Oct '07

I noticed the attached slide on Ted's presentation on Inkscape extensions. In the python example available online I see how to use the automatic GUI for scripts to collect text or String data. Can someone point out some examples or documentation that explains how to set up an automatic GUI for a script that uses enumerations or radio buttons? Would it be possible to use PyGTK from within an Inkscape extension script? Thanks for the help. Scott Huey

Composite Filter, arithmetic mode
by Tavmjong Bah 04 Oct '07

04 Oct '07

Hi, I've been studying the filter primitives. While the work that has been done is quite impressive, there seems to be quite a bit of polishing to do. I am currently having trouble with the Composite filter primitive. As I read the standard, the K values in the Arithmetic mode can be negative. This leads to the case where one or more of the calculated RGBA values can be negative. Of course these must eventually be clamped at zero. However, the calculation is done by using integers with the K values multiplied by a power of 255. The resulting integer is then normalized to be between 0 and 255 by the NR_NORMALIZE_31 function located in nr-pixops.h. This function uses the FAST_DIV_ROUND routine (also in nr-pixops.h) which is only valid for non-negative numbers.... thus it gives the wrong result (a positive value instead of zero). Can an expert suggest a fix? Tav

Re: [Inkscape-devel] Color Tweak - Option to not create new gradient
by rosros-3＠...112... 04 Oct '07

Xara's designers think that "named colors" is a great feature of their program and I agree with them. Changing the color of 100 objects without affecting 100 other objects that have the same current color on the canvas can be achieved easily with named colors (complicated selections may be needed otherwise). With two-stop gradients one must edit two stoppoints, with one-stop gradients just one ... of course. Linked gradients (and colors), that is unforked ones, can save SVG code and improve loading (and perhaps rendering) speed. Moreover, this feature is already there! So, why removing it? It just needs to be made more perspicuous ... and perhaps enhanced with "shades" of the same color, another great feature of Xara, for which the code in Inkscape is already there according to Jon Cruz!! Shouldn't Inkscape be made SVG-1.1-compliant (see the opensource Batik 1.7 [http://xmlgraphics.apache.org/batik/], which - for instance - renders SVG 1.1 feColorMatrix very well; try opening http://sourceforge.net/tracker/download.php?group_id=93438&atid=604306&file… in Inkscape)? rosros -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Scegli ciò che stai cercando tra migliaia di annunci, prova con Email.it Annunci, linserzione è gratuita!

CMS display adjustment change
by Jon A. Cruz 04 Oct '07

04 Oct '07

Hi, I just checked in an update with icc color profiles and setting display calibration. Now upon startup latest SVN Inkscape will search the standard locations for profiles ~/.color/icc /usr/local/share/color/icc /usr/share/color/icc Then under the misc preferences you'll have a checkbox for enabling display calibration, along with a drop-down combo box that allows you to pick between all RGB display profiles found. Give it a rundown and let me know how it's behaving. Thanks.

Getting the ID of the selection in a Python script for Inkscape.
by Redefined Horizons 04 Oct '07

04 Oct '07

I was wondering how to obtain the current selection from within an Inkscape script written in Python. I note that the getselected method in the inkex.py file contains a comment that says it "Collect selected nodes". Does this mean that it only returns the nodes from the selection? Does it return the DOM representation of the selection? What is the quickest way, if it is even possible, to obtain the current selection in Inkscape from a python script? I'm thinking maybe I can get an id of the selection with a helper method an then use some methods in to get the DOM element of the selection using the "id" attribute. I hope my question makes sense. I've been trying to read through some of the material online about writing scripts and/or extensions for Inkscape, but I must admit it is a little confusing for me. I appreciate your patient assistance. I will do my best to post a summary of any responses to this question on the Inkscape wiki if that would help other future script writers. :] Scott Huey

SVN version fails to compile

Hi, trying to build the SVN version of Inkscape (on my GenToo system) fails with widgets/sp-color-icc-selector.cpp:185: error: expected initializer before '*' token widgets/sp-color-icc-selector.cpp:193: error: 'DWORD' does not name a type widgets/sp-color-icc-selector.cpp:194: error: 'DWORD' does not name a type widgets/sp-color-icc-selector.cpp:197: error: variable or field 'getThings' declared void .... It looks as if a header file hasn't been included. Many thanks for a hint, Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany
