Was reading the official spec for GIF image format.
It is such a superbly written spec that it makes ZERO assumptions. In a snippet highlighted we can see that they specified that
GIF format makes no provision for error detection or correction; the input stream should be error-free.
Somethings that we take for granted, the official spec covers it so well.
What if someone creates an image format with error correction in-built. how cool would it be?
This is why I love reading papers and official specs. No better way of learning something in-depth.
