Package com.luciad.imaging.operator

Class TLcdSwipeOp

java.lang.Object

com.luciad.imaging.operator.ALcdImageOperator

com.luciad.imaging.operator.TLcdSwipeOp

public class TLcdSwipeOp
extends ALcdImageOperator

Composes two images by taking the left part of the input image and combine it with the right part of the second image with respect to a swipe line.

• Swipe operation can be used only with ALcdBasicImage input images
• If one of the input pixels of the input image has a "no data" value, the result for the current pixel is also "no data".

Example

 // Using the static method:
 ALcdBasicImage inputImage = ...;
 ALcdBasicImage secondImage = ...;
 ALcdBasicImage outputImage = TLcdSwipeOp.swipe(inputImage, secondImage, 350);

 // Using a data object:
 ALcdBasicImage inputImage = ...;
 ALcdBasicImage secondImage = ...;
 TLcdSwipeOp op = new TLcdSwipeOp();
 ILcdDataObject params = op.getParameterDataType().newInstance();
 params.setValue(TLcdSwipeOp.INPUT_IMAGE, inputImage);
 params.setValue(TLcdSwipeOp.SECOND_IMAGE, secondImage);
 params.setValue(TLcdSwipeOp.SWIPE_DISTANCE, 350);
 ALcdBasicImage outputImage = op.apply(params);
