Class CmykColorHelper


  • public final class CmykColorHelper
extends Object

    Helper methods to work with CMYK color presented as a signed 32-bit integer value. Provides the similar API as the com.aspose.imaging.CmykColor struct. It's more lightweight because CMYK color is presented just as Int32 rather than structure with internal fields. Please prefer to use static methods of this class when possible instead of the deprecated com.aspose.imaging.CmykColor struct.
