Example
This example changes all the objects in an annotation container so they use a red pen, a white brush and an Arial font.
| Visual Basic | Copy Code |
|---|---|
Public Sub AnnDrawable_AnnDrawable(ByVal container As AnnContainer) For Each drawable As AnnDrawable In container.Objects If drawable.SupportsPen Then drawable.Pen = New AnnPen(Color.Red, New AnnLength(1, AnnUnit.Pixel)) End If If drawable.SupportsBrush Then drawable.Brush = New AnnSolidBrush(Color.White) End If If drawable.SupportsFont Then drawable.Font = New AnnFont("Arial", New AnnLength(10, AnnUnit.Point), FontStyle.Regular) drawable.TextColor = Color.Red End If Next drawable End Sub | |
| C# | Copy Code |
|---|---|
public void AnnDrawable_AnnDrawable(AnnContainer container) { foreach(AnnDrawable drawable in container.Objects) { if(drawable.SupportsPen) drawable.Pen = new AnnPen(Color.Red, new AnnLength(1, AnnUnit.Pixel)); if(drawable.SupportsBrush) drawable.Brush = new AnnSolidBrush(Color.White); if(drawable.SupportsFont) { drawable.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular); drawable.TextColor = Color.Red; } } } | |
Remarks
This class holds common drawing information shared by all annotation objects in the Annotations class library.
You can query the properties of this class to easily figure out if a certain class supports pen, brush or font and quickly change them. For example the properties dialogs used in the automation mode do just that to test whether to display the pen options.
