As I mentioned in my previous post, Correct Photos of Documents – Ambient Lighting, most images of documents suffer from skew. There are two types of skew: two-dimensional and three-dimensional.

Text is typically parallel to the top and bottom of the paper. Simply put, two-dimensional skew is the angle of the text when compared to the top or bottom edge of the image. This type of skewing can occur in photos of documents as well as document images produced by a scanner. While it is relatively easy to correct with a simple rotate, determining the angle of rotation can be tricky. Fortunately, LEADTOOLS includes a DeskewCommand class that can determine the angle of skew.

Paperless, or paper-free, offices are getting more popular in all work environments. Because of this, digital printing is becoming more of the norm. With the use of the LEADTOOLS Document Writer and Virtual Printer, you can create a virtual printer and print to a PDF from any printable source. What makes this great is the simplicity of configuring the printer. Now let's get to the code!

This past weekend, I was very fortunate compared to so many people that recently faced and are still having to deal with Hurricane Florence. At home, the power is out, but there is no major damage. I am fortunate. Since there is nothing I can do at the moment about the power and everyone around me is safe, I decided to forget my first-world problems, go to the office, which does have power, and write a small and simple app that solves some common first-world problems. I am hoping that you will find this tool useful, too!

UPDATE

While most features in LEADTOOLS are backwards-compatible and older how-tos still apply in newer versions, the features discussed in this post have changed significantly in Version 20. Please refer to the following forum post for an updated version of this tutorial:

In my previous post, "Solution to 4 Common First-world Problems – Convert and Merge to PDF," I implemented a solution to convert images of documents to text-searchable PDF files. The source images were produced from a document scanner and the camera on my phone. Since that post, I have received some questions on how to improve the human readability of the PDFs that were originally camera images.
