Problem creating a simple button

**drdan** · 06 January 2009, 02:26 PM

I am trying to create a simple button with round corners and a round beveled edge. When I export it to a GIF there is a trace amount of white outlining the round corners where it should be transparent. I am using the button on a dark blue background.

I tried to fix this by putting the button on a small rectangle the same colour that my web page is using. I set the fill colour and the line colour to the same blue. When I use this button it puts a thin border around this added box in a light colour or blue. Why does it do that? Is there a way to prevent it?

Hi Dan,

Welcome to Talkgraphics.

The fringe you are seeing with your transparent gif files is due to antialiasing. To create the illusion of transparency and smooth round button, the pixels around the object you are exporting are blended with the colours of any background object. This prevent the jagged edges that would otherwise result from the pixels' rectangular shape.

When you export to transparent gif select only the shapes of your button and not the blue rectangle. That way the blending pixels will match to your page's background and not the white drawing board beneath.

Might also be your html code.

<img src="yourimage.gif" border="0" />

You can also use CSS to eliminate a border on all images.

Goes in between the <head></head> tags.

<style type="text/css">

</style>

This might need to be moved?
