How can I crop an image with rounded corners and a transparent background. I figured out how to crop the image to have rounded corners, but you can see white in the corners where it was rounded. I want them to be transparent so the image really does look like rounded corners. Anyone know how to do this?
You will have to set the canvas to transparent in the Properties panel and export the file as PNG 32.
Or possibly a PNG8, which is color limited (but still supports semi-transparent colors and multiple transparent colors), but doesn't need any special coding to implement, and doesn't have the possibility of locking IE 6.
