    • adjust

    • process

      private void process(Paletted8Image in, Paletted8Image out)

    • process

    • process

      public void process() throws MissingParameterException, WrongParameterException
      Description copied from class: Operation
      This method does the actual work of the operation. It must be called after all parameters have been given to the operation object.
      Overrides:
      process in class Operation
      Throws:
      MissingParameterException - if any mandatory parameter was not given to the operation
      WrongParameterException - if at least one of the input parameters was not initialized appropriately (values out of the valid interval, etc.)

    • setHueSaturationValue

      public void setHueSaturationValue(int hue, int saturation, int value)
      Set the values for the adjustment of hue, saturation and value (brightness). Saturation and value must be from the interval -100 to 100 (also see setSaturationValue(int, int)). Hue must be from the interval 0 to 359.
      Parameters:
      hue - the hue to be used for the complete image, between 0 and 359
      saturation - change of saturation, between -100 and 100
      value - change of saturation, between -100 and 100
      Throws:
      IllegalArgumentException - if one of the arguments does not stay within the valid interval

    • setSaturationValue

      public void setSaturationValue(int saturation, int value)
      Set the amount of change to saturation and value (brightness) for this operation, between -100 and 100. Calling this method also tells the operation not to modify the hue of the image.
      Parameters:
      saturation - change of saturation, between -100 and 100
      value - change of saturation, between -100 and 100
      Throws:
      IllegalArgumentException - if one of the two arguments does not stay within the -100 .. 100 interval
