My sample of this problem are here:
Unlike other Animated GIF packages, you can't simply select a color to
be transparent and save the gif. Instead, you have to work frame by
select a Frame
select the corresponding object
use the magic wand to select the color that you want to be transparent
click the "Selection Options" button at the top-middle
select "Make Selection Area Transparent"
Then repeat for each Frame - what a major hassle !!!
Then, after doing all that - I have an odd "ghosting" problem. The
GIF plays file if I click the "Run" button at the bottom of the Frames
bar - but when I save it, or when I view it in the preview pane - each
image "stays" for the duration until Frame 1 is repeated. The images
stack up and you see this weird trailing effect. Image Ready
(Photoshop companion) does the same thing.
Their help file is miserable - when you search for Transparent there
is one entry with one sentence about it:
"Makes the selected area in the selected object layer transparent"
That's it !!! I emailed them but no response after 2 days.
However, the one free tool, www.gifworks.com works perfectly !! You
simply load the file, click on the color you want to be transparent,
and save the gif. Still this was $44 and I want to get it to work -
any ideas?? Feel free to download the original GIF and see if you
also get that Ghosting effect when you make the outer portions
Transparent - I am so curious to see if you do.
