Reno Suite is Finally Done!

Jay Honeck opined

For pictures that are human made, like plain text and floor plans, gif or
png
is a better format than jpg.

I've heard that, but I have no idea why that is true. Can you explain,
please?


jpgs throw away information that the human eye does not really see in natural
pictures. It does so by, essentially doing a Fourier transformation, and
dropping the high frequency terms. If you do this to a line, a square wave,
the resulting picture becomes (in the extreme) a sine wave. That makes the
result blurred.
