img_compare merges 2 images using a selected mode. It is thus possible to compare images visually.
inImage1
This is an image.
inDatamap1
This is a datamap for Image1.
inImage2
This is an image.
inDatamap2
This is a datamap for Image2.
Border Value
Border value changes from 0 to 1 and defines the position of the border between the parts of the merged image.
Merge Mode
There are 6 merge modes (from 0 to 5). Mode 0 is vertical slice, 1 is horizontal slice, 2 is diagonal, 3 is solid (Image1), 4 is circle, 5 is checkerboard.
Switch datasets

out
The merged image.
The User Macro img_compare makes use of the Functional Macro ImageFunc and the UI Macro ImageUI.
An example application ImageEg is provided, which uses 2 different slices of the hydrogen data to display a merged image.
