Leadtools.WinForms Namespace > RasterImagePrinter Class : UseDpi Property



Gets or sets a value that indicates whether LEAD's automated scaling properties are used to account for the physical resolution of the image when printing FAX images.

Syntax

Visual Basic (Declaration) 
Public Property UseDpi As Boolean
Visual Basic (Usage)Copy Code
Dim instance As RasterImagePrinter
Dim value As Boolean
 
instance.UseDpi = value
 
value = instance.UseDpi
C# 
public bool UseDpi {get; set;}
C++/CLI 
public:
property bool UseDpi {
   bool get();
   void set (bool value);
}

Return Value

true Account for the physical resolution. Default value is true.

Example

For an example, refer to RasterImagePrinter and ImageRectangle.

Remarks

The physical resolution of an image is measured in dots per inch (DPI). When you load an image, the XResolution and YResolution properties are updated with the DPI values for the horizontal and vertical resolution. Some images have different horizontal and vertical resolutions. For example, the horizontal resolution of a fax image is typically twice its vertical resolution (for example 200 by 100). In such cases, the displayed images will appear elongated if you do not account for the resolution.

If the values of the XResolution property and the YResolution property are not equal, set the UseDpi property to true to have LEAD's automated scaling properties account for the physical resolution of the RasterImage when printed using Print

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
