Namespace: Microsoft.VisualStudio.Text.Editor
Assembly: Microsoft.VisualStudio.Text.UI.Wpf (in Microsoft.VisualStudio.Text.UI.Wpf.dll)

Syntax

'Декларация
Function GetMarkerGeometry ( _
    bufferSpan As SnapshotSpan _
) As Geometry

Geometry GetMarkerGeometry(
    SnapshotSpan bufferSpan
)

Geometry^ GetMarkerGeometry(
    SnapshotSpan bufferSpan
)

abstract GetMarkerGeometry : 
        bufferSpan:SnapshotSpan -> Geometry

function GetMarkerGeometry(
    bufferSpan : SnapshotSpan
) : Geometry

Parameters

bufferSpan
Type: Microsoft.VisualStudio.Text.SnapshotSpan
The span of text.

Return Value

Type: System.Windows.Media.Geometry
A Geometry that contains the bounds of all of the formatted text in bufferSpan.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	bufferSpan is not a valid SnapshotSpan on the buffer.

Remarks

If the span extends beyond one line, then GetLineMarkerGeometry is used to calculate the marker geometry, otherwise this method uses GetTextMarkerGeometry to construct the geometry.

The returned geometry may contain several disjoint regions if the span contains a mix of conventional and bi-directional text.
