This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Process data so DEFLATE works more efficiently
Are we still talking about PNG? Nowhere in the PNG standard is a description of changing the actual content of an image to make it compress better with DEFLATE. If you are thinking about the filter stage you should know that in this context an image filter is just creating a different representation of the same image, because it is fully reversible.
Sounds very pedantic. ive already given the only answer im gonna give, if you want to label it something different that's your business.
