<p>

        This test verifies the support for gamma correction of displayed PNG

        images.

      </p>

    </d:testDescription>

    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">

<p>

        Run the test. No interaction required.

    <d:passCriteria xmlns="http://www.w3.org/1999/xhtml">

<p>

        Several different images are displayed one above the other;

        if gamma correction is correctly performed based on the values in

        the gAMA chunk in the PNG file, the resulting displayed values are

        the same in all of the files (except for rounding error, which gives

        some artefacts at the right side of the lowest two  images due to the

        very high levels of gamma correction needed for this test)
