XAML Values

double

Double

String representation of a Double value equal to or greater than 0.0 but smaller than Double.PositiveInfinity. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

qualifiedDouble

A double value as described above, followed by one of the following unit specifiers: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Property Value

Type: System.Double
The desired font size to use, in device independent pixels). The default is determined by the SystemFonts.MessageFontSize value.

Any FontSize settings on child elements override this top-level setting.

The following example shows how to set the FontSize attribute of a FlowDocument element.

<FlowDocumentReader>
  <FlowDocument
    FontFamily="Century Gothic"
    FontSize="12"
    FontStretch="UltraExpanded"
    FontStyle="Italic"
    FontWeight="UltraBold"
  >
    <Paragraph>
      Any font settings on this paragraph would override the font settings
      for the FlowDocument.
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

The following example shows how to set the FontSize property programmatically.

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
// Set the desired column gap to 10 device independend pixels.
flowDoc.FontFamily = new FontFamily("Century Gothic");
flowDoc.FontSize = 12.0;
flowDoc.FontStretch = FontStretches.UltraExpanded;
flowDoc.FontStyle = FontStyles.Italic;
flowDoc.FontWeight = FontWeights.UltraBold;
