The Crop to Manually Specified Boundary in Native Layer Projection/Units option allows you to specify a
crop boundary in the native units of the selected overlay. When selected, this option will display the
Customize Collar Bounds dialog (pictured above) to allow specifying the bounds to crop to.
The Crop a Specified Number of Pixels Around the Edges of the Layer option allows you to specify a number
of pixels to crop of each edge of the selected overlay(s).
The Snap to Manually Specified Degree Boundary option allows you to specify that the collar for the selected
overlay will be on some degree boundary, like an even degree, of 0.5 degrees, etc. This way you can setup
cropping for a collection of maps that are all similarly aligned.
The Crop to Previously Selected Polygon(s) option specifies that you want to crop to the crop polygon(s)
(area) previously applied to the selected layer(s) using the Crop to Currently Selected Polygon option.
The Crop to Currently Selected Polygon(s) option specifies that you want to crop the selected layer(s) to any
area feature(s) currently selected with either the Feature Info or Digitizer Tools.
Band Setup Tab
Global Mapper User's Manual
The Band Setup tab (pictured below) is available for some types of imagery with 3 or more bands of data.
This tab allows you to control which bands of data are used for the red, green, and blue color bands. This is a
very useful tool when trying to extract different types of information out of multi-spectral imagery.
There is also an option for advanced users to allow disabling of the alpha (translucency) channel for an image.
This is useful if you have an image with bad alpha values (like all set to completely transparent) and you just
want to see the colors without applying the alpha values.
