I tend to be immediately suspicious when I hear a 'proof by popularity' argument.

What do you think of defining terminology by popular agreement? And what do you think of "proof by definition?"

I'm not arguing merlyn's "point", jepri¹. I suggested that his use of the term "lossy", in a way which isn't only different from but directly contradicts the accepted terminology, would only cause confusion and wouldn't help anyone understand the issues.

The PNG and JPEG specifications themselves use the the terms "lossy" and "lossless." The PNG spec defines them:

Lossless compression
Any method of data compression that guarantees the original data can be reconstructed exactly, bit-for-bit.
Lossy compression
Any method of data compression that reconstructs the original data approximately, rather than exactly.

We don't need to argue anything, we only need to agree on terminology.

1. Really, his point was obvious. JPEG has its own advantages and they are different from PNG's.
