Use
the Eyedropper tool to copy fill and stroke attributes from one
object and immediately apply them to another object. The Eyedropper
tool also lets you sample the image in a bitmap to use as a fill.
To apply the attributes of a stroke or filled
area to another stroke or filled area, select the Eyedropper tool
and click the stroke or filled area whose attributes you want to
apply.
When you click a stroke, the tool automatically changes
to the Ink Bottle tool. When you click a filled area, the tool automatically
changes to the Paint Bucket tool with the Lock Fill modifier turned
on.
Click another stroke or filled area to apply the new
attributes.
