When you select a field in the "field grid" in Invoice Verify, that field on the invoice is highlighted (or not highlighted) in the way that is specified by these settings.
When highlighting is used (that is, when HighlightPart is set to 1 or 2), you can adjust the color of the highlighting by specifying RGB colors using the HighlightRed, HighlightBlue, and HighlightGreen settings.
Example
With these settings, fields on the invoice image would be marked with a frame and yellow highlighting:
HighlightPart=2
HighlightRed=255
HighlightBlue=100
HighlightGreen=255
The above values for HighlightRed, HighlightBlue, HighlightGreen are the default values.
Valid values for HighlightPart
0 (frame only – default)
1 (highlighting only)
2 (both highlighting and frame)
