jakekara / png_structure.py

Created December 12, 2016 00:41

Just some idle poking around inside the PNG file format with python. Ugly code, maybe-useful comments.

	# Exploration in PNG
	#
	# Just poking through the PNG file structure.
	#
	# Found weird output when examining MacOS screenshots. They contain an
	# "iDOT" chunk, the purpose of which I couldn't determine. This chunk type
	# is not part of the PNG standard, and seems to break some programs'
	# ability to process these files, according to complaints I'm finding on
	# Google. See sample output below. If no one's already done it, maybe there
	# is some value in writing e script to strip out these invalid iDOT chunks.
