 double  String representation of a Double value equal to or greater than 0.0 but smaller than 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  Auto  Causes the page height to be determined automatically.  Equivalent to a property value of NaN. 

Property Value

A double value indicating the preferred height, in device independent pixels, for pages in the FlowDocument. A value of NaN (equivalent to an attribute value of "Auto") causes the page height to be determined automatically. The default value is NaN.

If viewed on a continuum, the MinPageHeight property takes precedence over the MaxPageHeight property, which in turn takes precedence over the PageHeight property. If all three properties are set on a given page, this is the order in which the properties are evaluated.

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

<FlowDocumentReader>
  <FlowDocument
    PageHeight="Auto"
    PageWidth="Auto"
    MinPageHeight="3in"
    MinPageWidth="5in"
    MaxPageHeight="6in"
    MaxPageWidth="10in"
  >
    <Paragraph Background="BlanchedAlmond">
      This uses automatic page sizing with minimum page size of 3 by 5 inches,
      and a maximum page size of 6 by 10 inches.
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

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

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
// Set PageHeight and PageWidth to "Auto".
flowDoc.PageHeight = Double.NaN;
flowDoc.PageWidth = Double.NaN;
// Specify minimum page sizes.
flowDoc.MinPageWidth = 680.0;
flowDoc.MinPageHeight = 480.0;
//Specify maximum page sizes.
flowDoc.MaxPageWidth = 1024.0;
flowDoc.MaxPageHeight = 768.0;
