Resolution Property

Summary

Resolution of the item in dots per inch (DPI).

Syntax

C++/CLI

public LeadSizeD Resolution { get; set; }

public:  
   property LeadSizeD^ Resolution 
   { 
      LeadSizeD^ get() 
      void set(LeadSizeD^ value) 
   }

Property Value

The resolution (in dots per inch) of the original image data if accounting for the logical size of the image when displayed is desired. Default value is 0,0.

Remarks

This value is important when UseDpi is used. A value of 0 means use the current screen resolution. This is the same value set in ScreenDpi.

For more information, refer to Image Viewer Items.
