Examples

The following code demonstrates the support of SelectiveColorLayer adjustment layer.

string sourceFileWithSelectiveColorLayer = "houses_selectiveColor_source.psd";

string outputPngWithSelectiveColorLayer = "houses_selectiveColor_output.png";

string sourceFileWithoutSelectiveColorLayer = "houses_source.psd";
string outputPsdWithoutSelectiveColorLayer = "houses_output.psd";
string outputPngWithoutSelectiveColorLayer = "houses_output.png";

    if (!object.Equals(expected, actual))
