Just like that minus the circle in the middle. You could create a striped gradient fiurst and then use the gradient tool in conical mode.

Re: [Gimp-user] Simple Radial Lines
Not at all, Eric! I like my script, mostly because I can always write others to perform like tasks. But... I am just AMAZED by the grid + polar_coord trick. I bet we could just create a GIMP PUZZLE CONTEST . The most incredible, and yet feasible, way to draw fnord in the GIMP wins. (And any postscript would be left out of such a contest - it's not made with the GIMP after all) Does photoshop have got an easier way to draw these Simple Radial Lines ? I remember using Deluxe Paint, in DOS - and there, there was a symetric mode one could enable - every stroke was mirrored N times around a common center, or in tiles, and this drawing could be made using that. Actually, Deluxe Paint, for simple it was, had some features that are not found around in any other program. JS -- Eric Pierce wrote: On Wed, 2003-08-06 at 21:02, Jeff Trefftzs wrote: 1.

It seems like it'd be so easy... If I understand what you're asking here (which sounds sort of like a spoked wheel), GFXShapes can do this for a half circle. It's the Fan shape without the tail (aka grip). Just create a new layer with a fan, duplicate, flip the dup vertically and then align the bottoms. You might want to clip the bottom of the half circle to remove the edge before you dup the layer. You can use GFXLayers to align the two layers exactly using point and click. I find myself using GFXLayers all the time - something I didn't expect I would be doing when I wrote it. These are part of the Graphics Muse Tools CD.

Does this solution only work in Linux? AFAIK. Gimp requires the ghostscript postcript engine to load Postscript prograns. I believe that if GStools is properly instaled in windows, GIMP for Windows should be able to load it as well. (if don't, that's a BUG and should be treated like one) You can download ghostscript and it's associated tools starting from: http://www.cs.wisc.edu/~ghost/doc/AFPL/get700.htm And if you gonna try it, let me know if it still doesn't work. regards, JS -- ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: [Gimp-user] Simple Radial Lines
Could not think of an easy way using the GIMP.
Actually, the only more or less easy way I could think off is using
a graphic turtle I am making in GIMP-Python.
Since that would be complicated I made an extra-gimp solution for you.
An Postscript Snippet.
Just paste the following postscript code in a plain text file, which
name ends in .ps , edit the number of rays to the desired one,
and them just open it as an image in the GIMP.
Enjoy it!

Re: [Gimp-user] Simple Radial Lines
That's it! Very cool solution.
As soon as you mentioned ps I started wondering if Sodipodi (or some other
vector dealy) could pull this trick off, but your code is perfect.
Manipulable and everything is rendered automatically.
Would make for a nice plug-in I imagine.
Thanks again!
