Clean Up a Bitonal Image of a Scanned Detail
Jeff Bartels of Autodesk covers the quick and the dead (basic but effective) of AutoCAD Raster Design cleanup of a scanned detail.
From the Civil Imersion blog.
I used to call Raster Design - "The Long Goodbye to the Sticky Back". A lot of drafting folks might remember those. Yuck!
Important but not said...if the image is a greyscale tif (your file type may vary) you must first convert it to bitonal. Easy in Raster Design.
