Colortrac 24120 Product Sales Guide 15
In this example there are two scans, one from each side of a map of the world. A large enough
canvas size is first selected and the two images are selected and placed into it. For best results
both images should have some overlapping data.
The zoom reveals that there is an area of overlap for the two scans. If the larger semi-
transparent image is moved left over the smaller image to the point where the lines A-A and B-B
become a single line the images can be joined. Any point in the overlapping areas of data can
be chosen as the join line – this is the choice of the operator.

The image left shows the two
images immediately before they
were joined.
Note that this method requires
separate image skew correction to
be carried out either on each
image separately using the normal
deskew control of Scanworks or
by using the V-tool which is part of
the flatbed Overlay editor.
