Code Tip: Converting PDF, IBM FileNet P8, Wang, and LEAD Annotations


Annotations are an important part of many document and medical imaging workflows. They allow users to mark up images with various shapes, notes, highlights, and redactions without having to permanently alter the image or document itself. One difficulty developers face is that annotations are not standardized. There are many standards, both open and proprietary, but not all of them play nicely with each other.

LEADTOOLS annotations use XML to store the annotation data. Since XML is easy to read and interpret, this makes our annotations a powerful intermediate format if your application needs to load and/or save another format. You can develop an application and use LEAD’s superior viewing, conversion, and drawing tools but still retain your original annotation format. Or if saving isn’t a concern you can simply have the peace of mind knowing that your application can load a huge variety of file formats and annotations that go with them.

Code Tip Examples

One of our developer support agents went on a rampage and created examples of some of the many ways you can convert annotations. Check out the links below going to our forum where you can download the example for the type of annotation conversion you need.

Don’t see your annotations on this list?

First, this isn’t a comprehensive list, so contact our support department and see if we support your annotations! LEADTOOLS developers are experts in this arena, so if you have an annotation format that is currently unsupported in LEADTOOLS let us know and we will be happy to work with you on getting that format added to our toolkit. We recently updated our libraries and the Document Viewer to load and save IBM FileNet P8 annotations and are happy to continue enhancing our products in ways that serve our customers well!
