I pulled a repeating pattern from someone else's PSD. Is there a way to figure out the size of the original pattern? I need to create an image with only one tile.
I believe the answer to your question was first posted in a similar thread in regards to exporting patterns by Jin.
In the pattern library popup, when you click on a pattern, the tooltip should tell you what dimension it is. Start a new document with this dimension, and fill using the pattern. You should end up with a non-repeated image of the original pattern size.
