Add Watermark to a Batch of Documents and Images in .NET and Java

Watermarking is a popular technique to indicate that the content or data inside a document is copyrighted. On the other hand, it is also used to place the company’s logo or some kind of label in the documents before they are shared within or outside the company. However, it is quite hard to apply the watermark to a bunch of documents one by one. It becomes harder if you have documents of various formats such as PDF, DOCX, PPTX, XLSX, EML, JPG, PNG, etc.

Best Practices in Metadata Management

Before going in-depth to Metadata management, let’s discuss what the metadata is? The Metadata summarizes basic information about data. In other words, it’s an information which describes the data that contained in something like a web page, document, or file.

A simple example of metadata for a document might include a collection of information like the author, file size, date the document was created, and keywords to describe the document.

Introducing a More Optimized and Simplified Electronic Signature API

Why change is considered as a hard but yet good thing to occur? Why the updates are important? This is because if there is no change there is no progress and staying the same over the time makes the things die.

A software that remains the same and doesn’t introduce any improvements or new features becomes obsolete.
