Author here. Hello everyone!
Feel free to ask me anything.
I'll go ahead and dispel some doubts I already see here:
- It isn't really a "new format". It's an update to the existing format.
- It is very backwards compatible.
-- Old programs will load new PNGs to the best of their capability. A user will still know "that is a picture of a red apple".
There also seems to be some confusion about how PNGs work internally. Short and sweet:
- There are chunks of data.
-- Chunks have a name, which says what data it contains. A program can skip a chunk it doesn't recognize.
- There is only one image stream.
