Re: [Inkscape-devel] spiral???

It probably would have >been good to mention this on the mailing list before removing the >feature; I suppose the thinking was that probably nobody cared one way >or the other. It is very strange reasoning!!! I STRONGLY DISAGREE. Sorry guys but we represent a very small share of the program's users, and even smaller of its potential users, both quantitatively (in number) and qualitatively (in not being professional designers). We should not take any serious feature decisions without as wide discussion as possible, and especially when we REMOVE something. Jabber is fine for quickly discussing small things, but this is a serious change which requires a balanced, slow, thorough discission. Jabber is not suited for this kind of discussions. Lauris did not invent this tool too; he copied it from other vector editors. Why do you think you better understand the needs of artists than, for example, creators of Macromedia Freehand (among others) which has the spiral tool??? >Does anyone use the spiral shape for anything? Hell YES, if only to amuse my 5 y.o. daughter! She will be BITTERLY disappointer by your decision. And seriously, I once spent an hour in Xara drawing a spiral by hand for one of my designs (Xara does not have a spiral tool), and it turned out to be so difficult that I quit, launched Freehand, created a spiral there, exported into EPS and then imported into Xara. So for me, the Inkscape's spiral tool is one of its very real advantages over Xara. I even mentioned it as such just a couple days ago to my wife, when she asked what was that new drawing tool I'm spending my time with recently! Even all that aside, how do you feel killing a feature which has almost 1000 lines of code, is well thought out, complete and convenient? There's simply no limitations to the kinds of spirals it can create - don't you appreciate that? Yes it has a bug, but show me a tool which has none! Were you seriously planning to add to the release notes, for example, "Answering many requests from impatient users, we finally managed to remove one the biggest Sodipodi's annoyances, the spiral tool?" Come on! It's just beyond me what kind of reasoning might lead to a decision like that. >Perhaps since we're not too crowded for space yet, and since the bug now >has a solution, that it would be prudent to let the spiral tool remain >until Nathan has a replacement for it? Yes, and only if that replacement is a strict superset. Sorry for sounding harsh, but this desicion really appalled me. I hope I convinced you to revert this decision, and moreover I hope you don't take decisions that suddenly kill almost a thousand lines of good code without a serious reason and a good discussion. _________________________________________________________________ STOP MORE 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…

Hi, I tested your dnd patch but I don't seem to be able to make it work. If I type in some SVG in your test program and drag it into inkscape, no object appears on the canvas, but there is a new empty <g> in the XML editor. If I type <text>abc</text>, after dragging it becomed <g id="123">abc</g>. _________________________________________________________________ Add photos to your messages with MSN 8.

[Fwd: [Scribus] Inkscape, vector graphics]
by Peter Linnell 22 Dec '03

22 Dec '03

-----Forwarded Message----- From: Magic Page <magicpage91@...127...> To: Scirbus List <scribus@...119...> Subject: [Scribus] Inkscape, vector graphics Date: Sun, 21 Dec 2003 20:00:16 -0500 Hi all, Not sure if many here are aware of the new program available for creating and handling SVG graphics. Inkscape is branching off from Sodipodi with a clear road map and I believe, a brighter future for a vectors grapic program for Linux. It already is impressive with the user interface and, I think, much easier and nicer to use because of that fact alone. Peter, of Scribus fame, turned me onto it just recently. I decided after compiling it, that I should make a real rpm available to other SuSE 9.0 users. I have created a RPM for SuSE 9.0 and passed it along to the Inkspace developers to include on their download site. The src.rpm is there also, so other linux distro users might be able to alter the spec file enough to use on their systems. SuSE is now putting all their Gnome programs in /opt/gnome, in an effort to more closely adhere to the LSB. I don't think Gnome is located in the same location for other distros. Anyway, give it a look and see if you don't like the changes as much as I did. It still gives you all the Sodipodi features, plus a few more and expect many more after the new year!

Two practical questions: - will Pango support kerning pairs? (currently they are ignored) - will it make it easier to implement (or even "for free") letterspacing?

rpm dependency
by Jon A. Cruz 21 Dec '03

21 Dec '03

This came up in the Jabber channel this morning: (09:52:02) edmack: Hi, I was trying to install the most recent rpm, and it told me I needed libXrand.so, and after searching on rpmfind.net, I couldn't find it.. what's the name of the package that provides it? (09:58:00) JonCruz: XFree86-devel Should we see if we can break free of that dependency?

Solved it myself with just a few more tweaks after sending out the mail.... OK, I finally managed to get the BBoxes right and the rotation and the transformation along with the appropriate magic to get the ghostscript driver to accept the %% directives.
