So the question is: Is there a feature within CS6 or a script that allows to resize a vector element with rounded corners without using the Direct Selection Tool (white arrow tool) and not changing the border radius? What would be great would be something like simply using the transform tool or something like a grid resize tool.
The simple answer is: No.
I have asked Adobe to add the feature. If you'd like to see it, please vote here:
And now some good news. David Jensen has written a nice little script to help. It's not perfect (doesn't handle multiple shapes on the one layer), but it does the trick in many situtions.
The script allows you to transform shapes (distorting them), then you can reapply the corners. You will need to remember the radius you used though.
The screenshot shows Windows, but the script also works on the Mac version of Photoshop.
I found a workaround. Using the menu command Image->Image Size... (Alt+Cntl+I) scales the rounded corners with the shape. So a rounded rectangle with 50 radius corners resampled with this method to half the size will now have 25 radius corners.
Since the shape is vector it won't degrade the quality of the graphic. If you don't want to resample the entire image you can drag the shape into a new document, resample, then drag back.
Hope this helps someone out there.
If you have Illustrator CS6 you can create a rectangle, select your rectangle go to menu
effect > stylize > round corners then select the proper styling for rounded corners. Finally copy/paste as a smart object into Photoshop.
No, Photoshop doesn't have a direct feature that does this for you. You could try writing a script for this or as a work around use the shapes tool and create the shape and delete and create it again if you need to change it.
You can use the shapes tool like this:
To access it you can press and hold the ellipse icon below the black arrow icon (path selection tool) and select rounded rectangle and draw using it. The shapes are drawn using paths and you can re-size them anytime you want and even change colors and set individual styles.
Or you will have to do using the rectangular marque tool and create a rectangle and smooth it out to the required radius.
After drawing the rectangle check on the "Show transformation Control" check box on the top.. You will get the handles to resize the rectangle..
