I was following the instructions on how to build a 3d button. I used the round rectangle tool to make a button, duplicated it, masked the top using the rectangle tool selected both objects and chose intersect from the Paths option to create the upper half of the button, which I then filled with a lighter colour and dragged it over the original Button to align (according to the red snap indicator) to cover the top half.
If I save this (at 300dpi) as a gif, everything aligns and looks OK, but if I use the gaussian blur as suggested from the tutorial, it leaves a lighter coloured edge around the top half of the gif, rendering it useless for any purpose. Is there a way to avoid this? I have tried less gaussian blur, but even with a level of 1 or less, this effect happens.
I’m using OSX, Snow Leopard 10.6.2 in case this is a bug or some kind.
I’ve since discovered that the problem is that when I make a gaussian Blur, it causes the object to “spread out” of its original area, so if I have a bottom layer button in one colour and overlay a similar sized top half of that button in a lighter shade, even if I align it perfectly, the moment I use a gaussian blur on it, this top object spreads outside the bottom layers constraints, as soon as I save this as a gif, it shows as a light coloured fringe around the button.
