Class TLcdResizeOp

java.lang.Object

com.luciad.imaging.operator.ALcdImageOperator

com.luciad.imaging.operator.TLcdResizeOp

public class TLcdResizeOp
extends ALcdImageOperator

Resizes an image, changing its resolution. The resulting resolution is the rounded result of the scales multiplied with the input resolution. The bounds of the image will remain unchanged.

Example

 // Using the static method:
 ALcdImage inputImage = ...;
 ALcdImage outputImage = TLcdResizeOp.resize(inputImage, 0.1, 0.1);

 // Using a data object:
 ALcdImage inputImage = ...;
 TLcdResizeOp op = new TLcdResizeOp();
 ILcdDataObject params = op.getParameterDataType().newInstance();
 params.setValue(TLcdResizeOp.INPUT_IMAGE, inputImage);
 params.setValue(TLcdResizeOp.SCALE_X, 0.1);
 params.setValue(TLcdResizeOp.SCALE_Y, 0.1);
 ALcdImage outputImage = op.apply(params);

apply

public final ALcdImage apply(ILcdDataObject aParameters)

Description copied from class: ALcdImageOperator

Applies this operator to the given input parameters. The parameters are stored in a data object which must be of the type given by ALcdImageOperator.getParameterDataType().

Specified by:

apply in class ALcdImageOperator

Parameters:

aParameters - the parameters for the operator

Returns:

the image produced by the operator

resize

public static ALcdImage resize(ALcdImage aSource,
 double aScaleX,
 double aScaleY)

Creates a resize operator for a given input image. The operator takes a scale factor for x and y as input.

Parameters:

aSource - the image to be processed

aScaleX - the scale factor in the x direction

aScaleY - the scale factor in the y direction

Returns:

the resize operator
