Constructor Details

FourChannelStackTester

public FourChannelStackTester(StackTester tester,
 ImageComparer comparer,
 boolean skipComparisonForRGB)

Creates for a tester and comparer.

Parameters:

tester - creates a stack to fulfill certain requirements, and performs the test with it.

comparer - a comparer used on the image-created when tested to check if it is identical to other(s).

skipComparisonForRGB - Iff true, comparisons are not applied to RGB images.
