Well, let's see...
I have an image open, happens to be RGB, no layers.
Works fine also if image is a single layer. The difference here is that
final image will have background color around it if not a layer, will
have transparent around it if a layer.
This is PS 7.
- choose Polygon tool
- In options bar at top, click Paths icon, the one in the middle between
Shape Layers and Fill Pixels
- Set Sides to 6 in box
- Draw hexagon (hint: press space bar without letting go of mouse button
to move around before completing)
- (additonal step, possibly) If you need to move, resize, rotate or
whatever, you can select the polygon with the Path Selection Tool or
Direct Selection Tool, and use Transform Path. Otherwise you don't even
need to use a selection tool.
- Right click in hexagon area/Make Selection/New Selection (only option
available), set any feathering, anti-alias on or off.
- Hex is now a selection, has marching ants
- Now Select/Inverse. Everything outside the hex is selected.
- Hit Delete key (or Edit/Clear)
- Maybe crop image to get ride of extra solid color around image.
Voila. Took a lot longer to type it than do it :)
Again, this is Photoshop 7, perhaps CS behaves differently on some step?
And of course, I'm sure there are other ways to accomplish this, always are.
