GetDigitWidth Method

GetDigitWidth(TextFormatInfo)

Gets the maximum width of the digits 0 through 9, in device-independent pixels. Useful formulas for wrapping a native implementation that returns pixels:

[Device independent pixel] = Pixel / [DPI Scale]

[DPI Scale] = DPI / 96.

Declaration

double GetDigitWidth(TextFormatInfo textFormat)

Function GetDigitWidth(textFormat As TextFormatInfo) As Double

Parameters

Type	Name	Description

Examples

class CustomGraphicsInfo : IGraphicsInfo
{
    public double GetDigitWidth(TextFormatInfo textFormat)
    {
        if ("Calibri" == textFormat.FontFamily)
        {
            return 8 * textFormat.FontSize / 11;
        }
        return 7 * textFormat.FontSize / 11;
    }
}
IGraphicsInfo graphicsInfo = new CustomGraphicsInfo();
TextFormatInfo textFormat = new TextFormatInfo();
textFormat.FontFamily = "Calibri";
textFormat.FontSize = 11;
double digitWidth = graphicsInfo.GetDigitWidth(textFormat);
