Updates: DigitizationLab and WebPlotDigitizer

September 2, 2014

This is just a small update on the status of DigitizationLab and the on going development of WebPlotDigitizer. I had taken a break of almost two months and have recently resumed the development of both the projects.

DigitizationLab is intended to be a desktop version of the WebPlotDigitizer program with added abilities to save and re-use calibration, masks, data etc. The desktop based implementation may also be better suited for automated tasks such as extraction of plots from documents, auto-detection of axes etc. I have made some progress on this, but there is still a lot more that has to be done. I am making the repository private for now and as it may not end up being a completely opensource software. Here is a screenshot of DigitizationLab running on Mac OS:

As for WebPlotDigitizer, I have collected a number of small enchancement requests and identified a few places where improvements are needed. I will be making these changes sometime this month.

Opensourcing DigitizationLab Desktop Software

June 15, 2014

I had received some requests for a desktop deployment of WebPlotDigitizer and in the last few weeks, I had been exploring that possibility under a project name "DigitizationLab". After exploring many UI toolkits and programming languages, I have finally settled upon a Qt C++ code. It is still at a very initial stage, but I finally have some seed code that can be worked upon in the future. This project will also be distributed with an opensource license (GNU GPL Version 3) and is available on GitHub: https://github.com/ankitrohatgi/digitizationlab.

The aim is not just to recreate WebPlotDigitizer in a native application, but also to go beyond what is practically feasible in a web-based environment. Some possibilities that I can think of right now are as follows:

• Batch process multiple images.
• Save and re-use axes calibration and digitization data.
• Read PDF documents and extract images automatically.
• Image editing capabilities (transformations, filters etc.) and annotations.
• Consume and share data from various database files or online resources.

Since this is also worked upon in my spare time, this will not receive full attention until I see some genuine interest in the project. The web-based application will continue being the priority until then. If you believe that DigitizationLab is something you would be interested in or have some suggestions, then feel free to drop me an email (ankitrohatgi@hotmail.com) or post on the discussion forum.

Here's a screenshot of DigitizationLab under development:

Projects Available!

I have started adding descriptions of a few interesting projects related to WebPlotDigitizer on the discussion forum. These projects are free to be picked up by anyone who wishes to contribute. Even partial contributions will be highly appreciated. Many of these do not require the intimate knowledge of the WebPlotDigitizer code. Look for the posts with [Available Project] in the subject line. If you find something interesting then drop a line in the forum or email me personally. Also, feel free to add to the existing discussions or start something new.
