Gets or sets the image unit value used to transfer images from the current TWAIN source.

Syntax

C++

public Leadtools.Twain.TwainImageUnit ImageUnit {get; set;}

Public Property ImageUnit As Leadtools.Twain.TwainImageUnit

public: 
property Leadtools.Twain.TwainImageUnit ImageUnit { 
   Leadtools.Twain.TwainImageUnit get(); 
   void set (    Leadtools.Twain.TwainImageUnit ); 
}

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

Imports Leadtools 
Imports Leadtools.Twain 
 
Public Sub ImageUnitPropertyExample(ByVal parent As IntPtr) 
   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(IntPtr 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(); 
}
