Is there a way to draw annotations programmatically from the code and direcly burn the annotations.

For example: When I load the image, I want to draw AnnText to a specific point and burn it to the image permanently.

Thank you

Hello,

In general, you can draw annotation objects programmatically and burn them into your image.
The details depend on the programming interface that you are using.
However, if you are using the LEADTOOLS .Net programming interface, you can create and burn Text objects as shown below:
+-----------------------+
//Draw AnnTextObject
Dim text As AnnTextObject = New AnnTextObject
text.Text = textString
text.Pen = Nothing
text.Brush = Nothing
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, 200, 400, 600, AnnUnit.Pixel)
//Add the AnnTextObject on the container
container.Objects.Add(text)
// Realize (Burn) annotation objects
AutomationAnn.Realize()
+-----------------------+

Please let me know if this helps.

Thanks,

Hello,

Do you mean that you want to put the TIFF image on the Annotation container as a stamp object?
What is the programming interface (COM, API, .Net, etc.) that you use?
