Class ALcdImageOperatorChain

java.lang.Object
com.luciad.imaging.operator.ALcdImageOperatorChain
public abstract class ALcdImageOperatorChain extends Object
Combines a number of image operators into a single function which requires only the input image to be supplied by the user. Simple, linear operator chains can be constructed using the supplied ALcdImageOperatorChain.Builder. More complex processing graphs can be constructed by creating custom implementations of this class.

The following code snippet illustrates the usage of the chain builder: 


 ALcdImageOperatorChain.newBuilder()
     .bandSelect(new int[] { 0, 1, 2 })
     .pixelRescale(new double[] { 0.8, 0.6, 0.8 }, new double[] { 0, 0.2, 0 })
     .build();
In this snippet, a band select operator which extracts the first three bands from an image is combined with a pixel rescale to adjust the image's color values. Note that both of these operators normally accept an image as one of their input parameters, but this is not set via the builder. Instead, it is passed to the chain's apply(com.luciad.imaging.ALcdImage) method, and it is the responsibility of the chain to ensure that the output of one operator is supplied as input to the next.
