Hello!

we are using LeadTools Document Imaging V17.5 and looking for a way to add a Hidden/Invisible Watermark to our 1Bit TIFF-Images.

We want to add not visible Copyright-Information to our technical drawings.

Thanks, Christoph

Christoph,

If you want to add an information that is hidden, you may try to get benefit of TIFF- comments and tags. For more information, please see the following help topic:
http://www.leadtools.com/help/leadtools/v18/dh/to/leadtools.topics.leadtools~l.topics.implementingtiffcommentsandtags.html

If you want to add a text information and blend it to the image pixel data, you can use our "AddMessageCommand" and "ExtractMessageCommand" image processing functions to write and extract message from image pixel data. See the following help topics:
