I am developing an app that is for viewing the return data from OCR'd fields on a bitonal TIFF image.

What I really need to do is to add 30 areas on this form, rectangles around the fields that were read for verification.

I am not sure if Annotations are what you should use, or Layers with rectangles drawn on them, or really if this how you would do this at all.

Any recommendations on what part of the toolkit to use? I didn't really want to convert it to a Windows Bitmap and write all of that additional code.

Sample is attached.

Any commentary is welcomed before I start this part of the project off!

Thoughts?

Hi Brandon

Why not just add shape layers?

You can add the layer to a IEViewer using LayersAdd(1):

And set the shape as rectangle using IEShapeLayer.Shape = 4

Thanks Nigel! I got my first layer loaded as an image. Is there an example piece of code for laying a Shape, rectangle in the layer?
