Transparency in a gif

I need to create a GIF, that incorporates a gradual fade to transparency. (The gif is a dividing line, that starts opaque and then fades to transparent.)

So far, I can create the required effect in CorelDraw 8, but which I export it as a GIF, it loses the transparency and fades to white rather than transparent. It there any way of creating this effect?

I have the latest Corel suite (Draw, PhotoPaint etc), PhotoShop, PaintShop Pro, and some other bits and bobs as well.

Any suggestions?

Try Photoshop as follows,

1) new image, transparent background
2) new layer, spray attachment and spray white with a lessening opacity as you move from the edge.
3) save as gif98a

Hi MorFF,

Thanks for your suggstions, but could you go into a bit more detail. I tried your answer, but when I imported the gif into the end publication (RoboHTML) it was not transparent. Maybe I missed something?

Thanks

Dan

p.s. Would exporting as a jpg help? Is there some restriction to the gif format that prevent transparent effects?

Dan,

You can't do transparency with a jpg.  Should work as above, stick your email on and i'll send you a photoshop example.

OK, I confess I don't know much about graphics, I'm really a programmer who's been told to do this as a sideline project.

My email is furseda@peltd.co.uk

Thanks MorFF

Thanks for the files. Actually, I managed to create a gif with the effect I wanted in CorelXARA, but your solution worked, so you get your points.

Thanks for your help.
