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);

Specified by:

apply in class ALcdImageOperator

Parameters:

aParameters - the parameters for the operator

Returns:

the image produced by the operator

                                       ALcdBasicImage aSecondImage)

Create a band merge operator with a specified input image.

Parameters:

aInputImage - the input image.

aSecondImage - the image to band merge the input image with.

Returns:

a new band merge operator.
