# A non regression test for the transform stack

Feature: transformstack

    Scenario Outline: mtransformstack
        When I launch videostitch-cmd with transformstack/<ptv>/<ptv>.ptv and "-d 0 -f 0 -l 0"
        Then I expect the command to succeed
        When I compare transformstack/<ptv>/<ptv>_output-0.jpg with transformstack/<ptv>/reference-1.jpg
        Then I expect the comparison error to be less than 0.03

        Examples:
            | ptv      |
            | circular |
            | elmo     |
