IC Imaging Control .NET

OverlayBitmap.Fill Method

OverlayBitmap.Fill Method

This method fills the entire overlay bitmap with the passed color.
Syntax:
[VB.NET]
Public Sub Fill( clr As System.Drawing.Color )
[C#]
public void Fill( System.Drawing.Color clr );
Parameter Description
color, clr

Specifies the color used to fill the OverlayBitmap.

Limitations:

Run time only. Only after ICImagingControl.LiveStart has been called once.

Remarks:

The Fill method is used to fill an entire overlay bitmap with the passed color. This overwrites all previously drawn texts and graphics. If the dropout color is passed to the Fill method, there is no overlay on the video (as the overlay is empty). The Fill method is only successful, after ICImagingControl.LiveStart has been called once.

Example:

This example demonstrates how to fill the entire overlay bitmap with the dropout color.

[VB.NET]
Dim ob As OverlayBitmap ob = IcImagingControl1.OverlayBitmap ' Enable the overlay bitmap for drawing. ob.Enable = True ' Set magenta as the dropout color. ob.DropOutColor = System.Drawing.Color.Magenta ' Fill the overlay bitmap with the dropout color. ob.Fill(ob.DropOutColor)
[C#]
OverlayBitmap ob = ICImagingControl1.OverlayBitmap; // Enable the overlay bitmap for drawing. ob.Enable = true; // Set magenta as the dropout color. ob.DropOutColor = System.Drawing.Color.Magenta; // Fill the overlay bitmap with the dropout color. ob.Fill(ob.DropOutColor);
