Class AlgorithmImageMath

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.awt.event.WindowListener, java.lang.Runnable, java.util.EventListener
    public class AlgorithmImageMath
extends AlgorithmBase
    Algorithm that adds, subtracts, multiplies, or divides an image by some user specified value. In addition, the square root or log of an image can be calculated. If the new image exceeds the range that can be stored in an image of that type the data is either clipped and stored in the original image. Or a new image of a type (int, float...) that can store the range of new data is generated.

    • Field Detail

      • clipMax

        private double clipMax
        Maximum clipping modes if data result value exceeds the capacity of image's data type.

      • clipMin

        private double clipMin
        Minimum clipping modes if data result value exceeds the capacity of image's data type.

      • clipMode

        private int clipMode
        Clipping mode. 
                                  CLIP          = 0;   clamp result data to the bounds of the input image type
                          PROMOTE       = 1;   promote image type so that the range of the result fits into
                                               the new image type. ( ie. byte to short).

      • finalize

        public void finalize()
        Prepares this class for destruction.
        Overrides:

      • calcInPlaceColor

        private void calcInPlaceColor()

      • calcInPlace

        private void calcInPlace()
        Generates the new data and places in the source image.

        note that if this method is canceled part-way through a multi-sliced image, it will almost certainly be partially adjusted. This is because to save memory buffer-space, it returns an adjusted slice back to the source image after processing it; it then takes out the next slice to alter it. Canceling a job causes the current slice will not be affected, but all previous slices will be.

      • calcInPlaceComplex

        private void calcInPlaceComplex()
        Generates the new data and places in the source image.

        private void calcStoreInDestColor()

      • calcStoreInDest

        private void calcStoreInDest()

      • calcStoreInDestComplex

        private void calcStoreInDestComplex()
        Generates the new data and places in a new (destination) image.

        Parameters:
        stType - starting type of image. Image will be promoted above this type if needed.
        Returns:
        type capable of storing full range of data. See ModelStorageBase for image types.
