I am able to generate the transparency.zip file and extracted it. But I am not able to open the .dat files with Microsoft Paint or any other program.
May be I have to re-construct that using some API to see the files like 021-equalized-image.dat as JPG or BMP formatted file.
Let me know if you have Java API to create the JPEG image from .dat file.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Robert, How to open the grayscale image with paint or other image viewer. You have pasted the images in the documentation. "The following fingerprint image can be reconstructed from this stage's binary data. Visualization itself is not part of transparency data."
How are you re-constructing with binary data.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The "reconstruction" involves transformation from the 64-bit raw grayscale to 32-bit RGBA and subsequent encoding in PNG format. There is no direct way to open the image.

These files contain raw grayscale image. Look at the transparency data documentation for details of the format:
