RasterCommandProcessor Class








Members 
Leadtools.ImageProcessing Namespace : RasterCommandProcessor Class
Batch processes a collection of RasterCommand object on a collection of RasterImage objects.
Object Model
Syntax
public class RasterCommandProcessor 
'Declaration
 

Public Class RasterCommandProcessor 
'Usage
 

Dim instance As RasterCommandProcessor
public sealed class RasterCommandProcessor 
function Leadtools.ImageProcessing.RasterCommandProcessor()
public ref class RasterCommandProcessor
Remarks
Use the RasterCommandProcessor class to perform "batch" image processing, where one or more commands are executed on one or more images.
Example

This example will load multiple images from disk and executes multiple image processing commands on them before saving the result into a single multi-page tif file.
