Define Pattern Not Enabled - Why???

[Shotster]

I follwed the simple instructions in the help system to the letter. I make a selection using the rectangular marquee tool, but the Define Pattern menu item under the Edit menu is not enabled. What do I have to do to define a pattern? Why is such a simple thing so diffucult?

Hey, I had the same problem earlier and as you said when I use the pen tool or the control command to select the area, the "define pattern" is disabled, but if I use the rectangle selection tool it works.

I know this is an old one, but in case anybody else has the problem and is seeking an answer not so far addressed, if you have  'Feather' selected (in other words, any option above 0 px) then 'Define Selection' isn't available.

This should be stickied as the correct answer; it's what causes the "semi-transparent" pixels that make "Define pattern" unavailable. The current stickied "solution" doesn't give a solution; it just defines the problem. Trying anything other than turning off the feather—e.g. flattening the layer or image to maike sure there are no transparent pixels—won't solve it.

Yes, I reduce the feather to 0px and define pattern enable again! thanks so much!

Try it with Photoshop Beta.  Seems to work for me now.
