PyGameTextRenderTester

This program essentially tests whether or not texts in various languages are being rendered correctly by pygame. Please see this thread as to why.

How does this work?

Essentially, this renders the same text-on-a-solid-background png using pygame and gimp using the exact same font, color, font-size, dimensions, etc, and checks the similarity of the rendered pngs using perceptual hash function (allowing for a slight dissimilarity threshold).

Usage:

$ ./main.py

Dependencies:

This mostly uses the standard python library modules but there are a few other modules/libraries and fonts that are required:

1. GIMP (also gimp-python, if it is not installed with GIMP)
2. pillow (pip install pillow)
3. imagehash (pip install ImageHash)
4. pygame (pip install pygame), obviously.

text.json:

To check the rendering of other languages/scripts, all one needs to do is to add the text to text.json file. The file is simple and the syntax is:

[	
	{
		"script": "<SCRIPT - 'Devanagari', 'Latin', etc.>",
		"font": "<Font to render the text with. Should be pre-installed>",
		"text": [
			"TEXT1",
			"TEXT2",
			"TEXTS CAN ALSO HAVE SPACES"
			]
	}
]

settings.py:

This file specifies the image dimensions, text size, text colour, background colour, etc.
