'Declaration
 
Public Property ImageUnit As TwainImageUnit
'Usage
 
Dim instance As TwainSession
Dim value As TwainImageUnit
 
instance.ImageUnit = value
 
value = instance.ImageUnit

            

            
public:
property TwainImageUnit ImageUnit {
   TwainImageUnit get();
   void set (    TwainImageUnit value);
}

Property Value

The image unit value used to transfer images from the current TWAIN source.
Remarks
This property internally gets or sets the image unit capability ICAP_UNITS. For more information on this capability, refer to http://www.twain.org and click on TWAIN Specification (Version 2.0).
Example
Copy Code  
Imports Leadtools
Imports Leadtools.Twain

Public Sub ImageUnitPropertyExample(ByVal parent As IWin32Window)
   Dim session As TwainSession = New TwainSession()
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None)

   Dim unit As Integer = CInt(session.ImageUnit)
   Dim bpp As Integer = session.ImageBitsPerPixel

   If unit <> CInt(TwainCapabilityValue.UnitInches) Then
      session.ImageUnit = CType(TwainCapabilityValue.UnitInches, TwainImageUnit)
   End If

   If bpp <> 24 Then
      session.ImageBitsPerPixel = 24
   End If

   session.Shutdown()
End Sub
using Leadtools;
using Leadtools.Twain;

public void ImageUnitPropertyExample(IWin32Window parent)
{
   TwainSession session = new TwainSession();
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None);

   int unit = (int)session.ImageUnit;
   int bpp = session.ImageBitsPerPixel;

   if (unit != (int)TwainCapabilityValue.UnitInches)
      session.ImageUnit = (TwainImageUnit)TwainCapabilityValue.UnitInches;

   if (bpp != 24)
      session.ImageBitsPerPixel = 24;

   session.Shutdown();
