Outline deletes solid colored areas of pixels from the raster image to leave raster outlines.
Outline the whole image
The outline thickness is the thickness in pixels that you want the remaining raster outlines to be after the solid areas have been removed.
As you move the slider you will see the raster image being outlined in the Preview Window.
If you are removing solid fills from an image that is a mixture of fills and lines ensure that the outline thickness you have chosen is not so small that lines are hollowed as well as solid fills.
Adjust the outline thickness if necessary.

Outline part of the image
If you only want to outline part of the image, choose the part you want to outline by windowing it or zooming into it, then follow the steps above. In Step 5, ensure the Apply changes to Full Image option is not selected.
Special note for color images
If you are working with a color raster image you can modify the way that Outline works by selecting a Pick Color.
If no Pick Color is selected Scan2CAD outlines solid raster areas of any color.
If a Pick Color is selected Scan2CAD outlines Pick Colored solid raster areas only.
