Class TLcdBandSelectOp

java.lang.Object
com.luciad.imaging.operator.ALcdImageOperator
com.luciad.imaging.operator.TLcdBandSelectOp
public final class TLcdBandSelectOp extends ALcdImageOperator
Extracts a subset of the color bands of an image and/or reorders the bands.

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:
   ALcdImage inputImage = ...;
   int[] bands = new int[]{0};
   ALcdImage outputImage = TLcdBandSelectOp.bandSelect(inputImage, bands);

   // Using a data object:
   ALcdImage inputImage = ...;
   int[] bands = new int[]{0};
   TLcdBandSelectOp op = new TLcdBandSelectOp();
   ILcdDataObject params = op.getParameterDataType().newInstance();
   params.setValue(TLcdBandSelectOp.INPUT_IMAGE, inputImage);
   params.setValue(TLcdBandSelectOp.INPUT_BANDS, bands);
   ALcdImage outputImage = op.apply(params);
