Remove Speckles
Images that have been scanned in from paper plans often have
unwanted black dots or "speckles" that can be removed with this
command. Depending on the image, there is a max speck size that can
be set. The larger the size indicated, the more specks will be
removed. You can specify the area to remove specks from based on
the entire drawing or by a closed inclusion polyline. Warning: this
command will update the Image seen on the screen as well as the
source Image.
