LuciadLightspeedClass TLcdExpandOp

java.lang.Object

com.luciad.imaging.operator.ALcdImageOperator

com.luciad.imaging.operator.TLcdExpandOp

public class TLcdExpandOp
extends ALcdImageOperator

Expands an image.

Note: Expanding can affect the spatial bounds of the ALcdBasicImage and should hence be used with care when working with ALcdImageMosaic as the bounds of an individual ALcdBasicImage should not be altered.

Example

 // Using the static method:
 ALcdBasicImage inputImage = ...;
 ALcdImage outputImage = TLcdExpandOp.expand(inputImage, 0, 0, 1350, 675);

 // Using a data object:
 ALcdBasicImage inputImage = ...;
 TLcdExpandOp op = new TLcdExpandOp();
 ILcdDataObject params = op.getParameterDataType().newInstance();
 params.setValue(TLcdExpandOp.INPUT_IMAGE, inputImage);
 params.setValue(TLcdExpandOp.EXPAND_X, 0);
 params.setValue(TLcdExpandOp.EXPAND_Y, 0);
 params.setValue(TLcdExpandOp.EXPAND_WIDTH, 1350);
 params.setValue(TLcdExpandOp.EXPAND_HEIGHT, 675);
 ALcdImage outputImage = op.apply(params);
