com.luciad.imaging.operator.TLcdCompositeOp

public class TLcdCompositeOp
extends ALcdImageOperator

Composes two ALcdBasicImages. This operator results in an image that covers the (spatial) union of the input images.

The composite contains the pixels of the first image without any change. However if the second image may be re-sampled if its pixel grid does not align with that of the first image (ex. due to a different pixel size).

Note:

• Compositing can result in an ALcdBasicImage with a different spatial bounds from the 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 = TLcdCompositeOp.composite(inputImage, secondImage);

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

Compose two images.

Parameters:

aInputImage - the input image.

aSecondImage - image to overlay on top of the input.

Returns:

the input image with the second image on top of it.
