There are a couple ways to add a border to all the layers of an animated GIF in ImageReady
without adding it to each layer one at a time. The easiest way to add a border to all layers in one shot is to make a new layer and have it be the top layer. What ever you do in that top layer, can affect the other layers.
Here’s an animation with 7 frames (layers).
Let say I want to add a simple square 1 pixel black border to it. So, without any layers active, I create a new layer (layer 8 in this example):
That gives me a new blank transparent layer. What ever I do to this layer (Fill, Stroke, etc), will filter down to all the other layers.
So…make that layer active by clicking on it and do a Select All (Ctrl+A).
That will give you the crawling ants dashed border around your composite image:
Just apply a Stroke and the border will be added to the current layer as well as the rest below it:
And you’re done. You now have a border on all frames in the animation. Cheers.
