Class TLcdBandMergeOp

java.lang.Object
com.luciad.imaging.operator.ALcdImageOperator
com.luciad.imaging.operator.TLcdBandMergeOp
public final class TLcdBandMergeOp extends ALcdImageOperator
Merges the bands of two images together.

The bands of the second image are added sequentially to the first, without reordering. Band merging is currently restricted to a maximum of 4 bands. This operator can for example be used to merge three grayscale bands and interpret them as RGB. For color data the bands should generally not be re-ordered. Otherwise they may or may not be interpreted as a color anymore. See here for details.

Example


 // Using the static method:
 ALcdBasicImage redImage = ...;
 ALcdBasicImage greenImage = ...;
 ALcdBasicImage blueImage = ...;
 ALcdBasicImage outputImage =
   TLcdBandMergeOp.bandMerge(
     TLcdBandMergeOp.bandMerge(redImage, greenImage),
     blueImage
   );

 // Using a data object:
 ALcdBasicImage redImage = ...;
 ALcdBasicImage greenImage = ...;
 ALcdBasicImage blueImage = ...;
 TLcdBandMergeOp op = new TLcdBandMergeOp();
 ILcdDataObject params = op.getParameterDataType().newInstance();
 params.setValue(TLcdBandMergeOp.INPUT_IMAGE, redImage);
 params.setValue(TLcdBandMergeOp.SECOND_IMAGE, greenImage);
 ALcdBasicImage outputImage = op.apply(params);
 params = op.getParameterDataType().newInstance();
 params.setValue(TLcdBandMergeOp.INPUT_IMAGE, outputImage);
 params.setValue(TLcdBandMergeOp.SECOND_IMAGE, blueImage);
 outputImage = op.apply(params);
