CopyImageCommand Class

Java
@interface LTKernelCopyImageCommand : LTRasterCommand
public class CopyImageCommand extends RasterCommand
Remarks
After the command is run, a copy of the current page of the source image will be in the CopyImageCommand.DestinationImage property. This property will hold a copy of the image, so the user is responsible for freeing this image after using it.
This command supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical Imaging toolkits.
This command supports unsigned data images, but not signed ones.
This command does not support 32-bit grayscale images.
This function can only process entire images. It does not support regions.
Note: All RasterCommands in this assembly modify the underlying properties of the input RasterImage, including but not limited to:
- BitsPerPixel
- Data
- IsMirrored
If you wish to avoid RasterImage property fidelity loss, pass a clone of your RasterImage to all RasterCommands in this assembly.
