GraphicsDpi Class

Enables you to calculate the DPI values associated with specific units of measure (and vice versa).

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Data.v18.1.dll

Declaration

C#

public class GraphicsDpi

VB.NET

Public Class GraphicsDpi

Example

This example illustrates how to adjust the document margins from one DPI value (corresponding to tenths of a millimeter) to another (corresponding to device-independent pixels) by using the XRConvert.ConvertMargins method.

C#

using DevExpress.XtraPrinting;
using DevExpress.XtraReports.UI;
// ...

void ConvertMargins(){ 
printableComponentLink.Margins = XRConvert.ConvertMargins(printableComponentLink.Margins, 
    GraphicsDpi.TenthsOfAMillimeter, 
    GraphicsDpi.DeviceIndependentPixel);
}

VB.NET

Imports DevExpress.XtraPrinting
Imports DevExpress.XtraReports.UI
' ...

Private Sub ConvertMargins()
    printableComponentLink.Margins = XRConvert.ConvertMargins(printableComponentLink.Margins, _ 
    GraphicsDpi.TenthsOfAMillimeter, _ 
    GraphicsDpi.DeviceIndependentPixel)
End Sub
