Attached is a Javascript project that demonstrates how to do image processing commands on the document viewer.

In the example remember that with SVG the white part isn't technically part of the image, so it won't be inverted making your black text white on white.

Unfortunately, the original post here used our older HTML5/JS Document Viewer demo which relied on our older REST services for loading the file and those REST services have since been deprecated. The error "Error Loading Document" that you are seeing is due to the Javascript libraries not being able to find the REST service endpoints via an AJAX call to request the document.

Error Loading Document

The latest version of the demo references backend services developed in either .NET or Java to load the documents. Below is a forum post on how to set up a simple version of the latest HTML5/JS Document Viewer demo with using the ASP.NET MVC Web API as an external service to load the documents:


We also have deprecated the LoadDocumentCommands and the DocumentFactory.loadFromUri function is now used to request the document from the backend service:


The post I linked above would allow you to work with the latest HTML5/JS Document Viewer demo in the same manner that you are attempting to do with the original forum post.

To get access to the latest HTML5/JS Document Viewer demo, you will need to latest version of LEADTOOLS 19 which you can get from here:
