CodeImageGenerator is a Python script, which converts Java or Python files/functions to images. This includes a rough custom syntax highlighting with Pygments.

I personally use this to convert short code snippets for empirical research on program comprehension (see Brains on Code). This means the script is very personalized to my usage, and probably not directly useful to you without changes.

The main feature is to read all files from a directory, attempting to add syntax highlighting, and finally creating matching images.

Implemented so far:

• Reads all files from a directory, and parses one at a time
• Extracts just the function code from the file (and ignores the class, comments, etc around it)
• Uses Pygments to create syntax highlighting for the code
• Parses Pygments syntax highlighting to fit on the image
• Dynamically reduces font size if the code doesn't fit the screen
• Option to either strip boilerplate code and reduce to single method (or use full file)
• Rough support for Java and Python functions
• Rough image creation

Things I may add in the future:

• Better and cleaner (Python) code...
• Better configuration (in particular the output color scheme)
• Command line support
• Allow functions besides public int, public String, public boolean, and a couple of other static ones
• Only read Java files
• Support for more languages than just Java and Python

The project should run in any Python environment. It was developed and tested with PyCharms.

Do you want to fix my horrible Python code? Feel free to create a pull request :)

Thank you!
