TIFF Layers

[q1w2e3r4t7]

How can i access, manipulate, and create different layers in a TIFF file?

 

For example, using 'Microsoft Office Document Imaging' (MODI) you can open an existing TIFF file, create text & notations on it, save it, then reopen and edit the text previously created, and or delete it and the other notations.

 

I would like to be able to do the same in VB.net.

 

In Vb.net, i have added reference to the MODI and can load and display the image, however i can't figure out how to pull out the layers.

 

I have tried searching google & this site and can't find any help.

 

If someone can point me in the right direction or provide code it would be greatly appreciated.

 

Thanks.
