In CVS head there also is (gimp-vectors-bezier-stroke-new-ellipse ...) which could be used, but arguably the SVG import is still simpler since it immediately creates a path object, which needs to be created manually for -stroke-new-ellipse first. This will not be backported to 2.2.x, you have to wait for 2.4 to see this in a stable release.

The best way to create a path that represents a perfect circle is probably to import an SVG from a vector editor or to open the Script-Fu console and use something like (gimp-path-import-string 1 "" -1 0 0) Yes, we should definitely add an easier way to do this, especially since all the functionality for basic shapes is already available in GIMP, it is just not exposed in any usable way.

Just thought this might be more useful on the list. ;-) On an added note. I gave up trying to use these options. The advice given was excellent and got me a lot closer. But at that scale it just couldn't produce the clean circle I wanted. I came away with 2 options; 1. Make a big circle and scale down (works well). 2. Hand build a perfect symmetrical path. I went with option 2 in the end and I'm happy with the results. Thanks very much Adam P.S. Give us your number and I will fax it to you. It's authentic and everything (got a ridiculous student debt to prove it). Although it's a Comp. Sci. it didn't help much :-D --- Begin Message --- Hi, Adam Cooper wrote: But, hang on, whilst hovering over the "Selection to Path" button it tells me I can press shift to get "Advanced options". Whoa there. They're not advanced options, they're uber-extra-super advanced options. Do you need a degree to use them? Well, yes. Fax me your B.Sc. and I'll put you on track. What exactly do I need to alter to encourage my path to more accurately follow the selection boundaries? Joking... Essentially, all the "small" numbers (<1) can be made smaller to improve the outline. The numbers around 1 - 5 you'll probably have to mouse-over, and guess. 'corner surround' could be a bit bigger, 'Filter iteration count' can go up to 8 or 10, "filter percent' can get tuned down to 0.2 or so, 'subdivide search' should be as small as is reasonable - 0.01 for example. 'Subdivide threshold' can also get a little bit smaller (but not too much). Play around :) Cheers, Dave. -- Dave Neary [EMAIL PROTECTED] Lyon, France --- End Message --- ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
