boxedit, a web-based box file editor

[Dan Vanderkam]

I had to edit a few Tesseract box files to generate training data recently and didn't find any of the existing tools to my liking. I wanted something that ran on Mac OS X and showed letters inside their boxes.

So I built a web-based tool which I'm calling boxedit.

Here's the tool: http://www.danvk.org/boxedit/

Demo with preloaded data: http://www.danvk.org/boxedit/demo.html

Source code & instructions: https://github.com/danvk/boxedit/

A few things to like about it:

- It's entirely browser-based, so it runs on any platform and requires no installation.

- You can use the browser's zoom in/out features.

- It shows OCR'd letters on top of the source image, so the accuracy is easy to gauge.

- It can split boxes N ways.

- You can edit the raw box data or use the GUI, either works & they stay in sync.

- It's easy to get going: drag & drop an image and its box file to get started.

A few things to dislike:

- The UI could use some work: the overlaying of transcribed letters could be much clearer.

- Saving your changes back to disk is tedious (my best solution is to copy/paste back into the box file).

- Missing a few important features (e.g. n-way merge and moving/resizing boxes visually)

If people find this useful, I'm happy to polish it a bit more. Feel free to file issues on GitHub.

Nice done. But how to install the missing components?

TIA

What do you mean by "missing components"?

The 3rd party JavaScript code. It would be enough to describe it in an installation HOWTO on github.

Fair enough! I posted some instructions here:

Basically, you need to run "npm install".
