This example will load a 24 bits per pixel CMP image and save it to a stream.

Visual Basic

Copy Code

Public Sub RasterImageViewer_Save1(ByVal viewer As RasterImageViewer)    Dim srcFileName As String = "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1.cmp"    Dim destFileName As String = "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image1_SaveStream3.bin"    ' Load the source image    viewer.Load(srcFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1)    ' Create a memory stream    Dim ms As MemoryStream = New MemoryStream()    ' Save this image to the stream after the header    Console.WriteLine("Saving the image")    Dim position As Long = viewer.Save(ms, 0, RasterImageFormat.Cmp, 24, 100)    Console.WriteLine("{0} bytes saved to the stream")    ' Save the stream to a file    'INSTANT VB NOTE: The following 'using' block is replaced by its pre-VB.NET 2005 equivalent:    ' using (FileStream fs = File.Create(destFileName))    Dim fs As FileStream = File.Create(destFileName)    Try       ms.WriteTo(fs)    Finally       CType(fs, IDisposable).Dispose()    End Try    ms.Close()    ' Make sure the saved file works       ' Save the image to disk    Console.WriteLine("Loading the file back")    viewer.Load(destFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1) End Sub

You can set the qualityFactor parameter to a value from 2 to 255 when saving JPEG and LEAD CMP compressed images, where 2 represents the highest quality and 255 the most compression.

If the image is 8 bits per pixel or greater, use the LEAD CMP format or one of the JPEG (JTIF or JFIF) formats to save disk space.

If the image is 1 bit per pixel, use the LEAD 1-bit format or a CCITT Group 3 or 4 format to save disk space.

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Vista, and Windows Server 2003 family
