Rounded Corners with Transparency
Posted: Wed Jun 20, 2007 12:44 pm
Hi,
I have spent hours and hours trying to come up with a solution and I simply cant seem to do it. What I am trying to do is, using GD2, draw a rectangle (with varying stroke) which has smooth rounded corners. The problem is that it is a border to be overlayed over a background image so the rectangle and corners need to be transparent.
I have had some success by creating graphics for the corners but when they are resampled to create the antialiasing effect it alters the colour so when I set the transparency, only some of the pixels are removed.
Can anyone help??
