Object Model

SizeCommand Class

Syntax

Visual Basic (Declaration) 
Public Class SizeCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As SizeCommand
C# 
public class SizeCommand : RasterCommand, IRasterCommand

Example

This example will convert an image to a thumbnail size before saving it to disk.

Public Sub SizeCommandExample()
      Dim codecs As RasterCodecs = New RasterCodecs()

      Dim srcFileName As String = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp")
      Dim destFileName As String = Path.Combine(LEAD_VARS.ImagesDir, "SizeCommand.bmp")

      ' Load the source image from disk
      Dim image As RasterImage = codecs.Load(srcFileName)
      Dim command As SizeCommand = New SizeCommand()
      command.Width = 128
      command.Height = 128
      command.Flags = RasterSizeFlags.Resample
      command.Run(image)

      ' Save the image back to disk
      codecs.Save(image, destFileName, RasterImageFormat.Bmp, 8)

      ' Clean Up
      image.Dispose()

SilverlightVBCopy Code
Public Sub SizeCommandExample(ByVal image As RasterImage, ByVal destStream As Stream)
   Dim codecs As RasterCodecs = New RasterCodecs()
   Dim command As SizeCommand = New SizeCommand()
   command.Width = 128
   command.Height = 128
   command.Flags = RasterSizeFlags.Resample
   command.Run(image)

   ' Save the image back to disk
   codecs.Save(image, destStream, RasterImageFormat.Bmp, 8)

   ' Clean Up
   image.Dispose()
End Sub

Remarks

This command resizes the image passed to the RasterCommand.Run method. If you want to keep the original-size image and create a new resized version, use ResizeCommand.
