1. Re: How to create clipping paths shape like a slice of a circle?
Gyno-jiz Sep 1, 2010 10:24 AM (in response to avpromedia)Basically, just set guides on the four bounding tangents of the circle, and also two bisecting it horizontally and vertically. Use the resulting guide intersections to draw the eight sections of the circle. Then just use the intersect mode in your path tool to overlap each of those 8 triangles with a copy of the original circle.

2. Re: How to create clipping paths shape like a slice of a circle?
avpromedia Sep 1, 2010 11:11 AM (in response to Gyno-jiz)It works! Thanks.
Is there a general solution that would work for arbitrary number of slices, let's say 7 instead of 8 slices?
I tried doing it myself was was successful, but is there a simpler way?
using the guides already created per your suggestion
draw a circle
draw a rectangle to cover the right half of the circle
cut away the right half of the circle
rotate the half circle by 51.4 degrees, set the rotation center to the previous center of the circle
draw another rectangle like the previous one
intersect this rectangle with the rotated half circle -- what remains is a 51.4 -degree slice, or 1/7 of a circle
once I have one slice, I can duplicate it and rotate it 6 more times to create the other 6 slices. Althought the last slice may not complete the circle due to cumulative round-off error. I can get over this by not creating the last slice, and just put a photo there without a clipping path, and put the 6 other photos with their clipping paths on top of this one.

Zeno Bokor Sep 1, 2010 12:04 PM (in response to avpromedia)Not really, no as Photoshop isn't very good with vectors. If you have and know Illustrator then try using that

Semaphoric Sep 2, 2010 9:41 AM (in response to avpromedia)Here's another way:
Make a circle and a square that covers one quadrant of the circle. Select the square with the Path Selection Tool. Edit > Free Transform, using the reference point that corresponds to the center of the circle, and 90 minus the angle of the slice into the Horizontal Skew field. Hint: you can copy the results from the Windows Calculator and paste them directly into Photoshop for this. This will give you greater precision that you might care to enter by hand.
Once you have committed the transform, select 'Intersect shape areas' in the option bar for the Path Selection Tool, and click Combine. There's your slice.
