Francis,

If you mean that you want to create a Text annotation object programmatically, the details depend on the programming interface (C DLL, .Net classes, etc.) that you use.
For example, if you are using LEADTOOLS .Net classes, you can create a Text annotation object by using the following code:
+---------------+
private void AnnTextObject_AnnTextObject(AnnContainer container, string textString)
{
AnnTextObject text = new AnnTextObject();
text.Pen = new AnnPen(Color.Red, new AnnLength(3));
text.Text = textString;
text.Brush = null;
text.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular);
text.EdgeMargin = AnnLength.Empty;
text.Alignment = StringAlignment.Center;
text.LineAlignment = StringAlignment.Center;
text.TextRotate = AnnTextRotate.Rotate0;
text.Bounds = new AnnRectangle(100, 100, 100, 100, AnnUnit.Pixel);
container.Objects.Add(text);
}
+---------------+
For more details, please refer to the LEADTOOLS .Net documentation.

If you mean something else, please provide me with more details about your requirements.

Thanks,

Hi Maen,

Could you provide the code with the definition of the container in VB .Net? And how annotation is overlayed to the exisiting image in the viewer control.

Thanks

I am attaching a VB.Net 2008 project that shows how you can create an AnnTextObject programmatically using LEADTOOLS v17.5 .Net classes.

Thanks,
