[Gimp-user] creating a circled area in an image

[Bob Krovetz]

I would like to write a program that would automatically circle an area
of an image that contains a given color.  For example, circle the areas
that are "blue".  I would use a range of color values to define "blue",
and the images would be in JPEG format.  Can I do this with the GIMP?
The image would contain only one instance of the color.

Thanks,
Bob
