Public Property PagePadding As Thickness

Property Value

Thickness

A Thickness structure that specifies the amount of padding to apply, in device independent pixels. The default is a uniform thickness of zero (0.0).

Examples

The following examples show various ways to set the PagePadding attribute of a FlowDocument element.

<FlowDocumentReader>
  <FlowDocument PagePadding="10">
    <Paragraph>Padding is 10 pixels all around.</Paragraph>
  </FlowDocument>
</FlowDocumentReader>

<FlowDocumentReader>
  <FlowDocument PagePadding="1.5in">
    <Paragraph>Padding is 1 and a half inches all around.</Paragraph>
  </FlowDocument>
</FlowDocumentReader>

<FlowDocumentReader>
  <FlowDocument PagePadding="5,10,5,10">
    <Paragraph>Padding is 5 pixels on the right and left, and 10 pixels on the top and botton.</Paragraph>
  </FlowDocument>
</FlowDocumentReader>

<FlowDocumentReader>
  <FlowDocument PagePadding="0.8in,20,0.8in,20">
    <Paragraph>Padding is 1 eigth of an inch on the right and left, and 20 pixels on the top and botton.</Paragraph>
  </FlowDocument>
</FlowDocumentReader>

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

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));

// Padding is 10 pixels all around.
flowDoc.PagePadding = new Thickness(10);
// Padding is 5 pixels on the right and left, and 10 pixels on the top and botton.
flowDoc.PagePadding = new Thickness(5, 10, 5, 10);

Dim flowDoc As New FlowDocument(New Paragraph(New Run("A bit of text content...")))

' Padding is 10 pixels all around.
flowDoc.PagePadding = New Thickness(10)
' Padding is 5 pixels on the right and left, and 10 pixels on the top and botton.
flowDoc.PagePadding = New Thickness(5, 10, 5, 10)

Remarks

PagePadding can be described as uniform in all directions (PagePadding="10"), or as four distinct values that represent left, top, right, and bottom padding independently (PagePadding="5,0,10,20").

If a specified padding thickness exceeds the corresponding page dimension (for example, the sum of the left and right padding widths exceeds the page width), the thickness of the padding will be proportionally reduced to be no greater than the relevant page dimension.

XAML Attribute Usage

<object PagePadding="uniformThickness"/>  
- or -  
<object PagePadding="independentThickness"/>  
- or -  
<object PagePadding="qualifiedUniformThickness"/>  
- or -  
<object PagePadding="qualifiedIndependentThickness"/>

XAML Values

uniformThickness
String representation of a single Double value to apply uniformly to all four thickness dimensions. For example, a value of "10" is equivalent to a value of "10,10,10,10". An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

independentThickness
String representation of four ordered Double values corresponding to independent thickness dimensions for left, top, right, and bottom, in this order. The four values must be separated with commas; spaces are not allowed. For example, "5,10,15,20" results in 5 pixels of padding to the left of content, 10 pixels of padding above content, 15 pixels of padding to the right of content, and 20 pixels of padding below the content.

qualifiedUniformThickness
A value described by uniformThickness followed by one of the following unit specifiers: px, in.

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

in is inches; 1in==96px

For example, "1in" provides uniform padding of 1 inch in all directions.

qualifiedIndependentThickness
A value described by independentThickness, with each independent value followed by one of the following unit specifiers: px, in.

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

in is inches; 1in==96px

For example, "1.5in,0.8in,1.5in,0.8in". Unit specifiers may be mixed or omitted from one or more values.
