Hello all.

I just passed an exam in image and video techniques, and I can confirm that
this is indeed feasible ;)

 Aaron. 

And Mr. Fenton is right about what he said about not seeing further
degradation after several saves. That coincides with the way JPEG Baseline
compression works. [It makes blocks of 8 x 8 pixels values, performs a
Discrete Cosine Transform -passing to the frequency domain-, quantize the
matrix of coefficients (this is were the quality percentage is applied), and
compress the new values (most of them are zeroes now) forming a bit stream
that is sent to the file.]

(Incidentally, as an assignment l had to program a plug-in in C for the GIMP
program, in order to compare the different qualities achieved with the JPEG
compression. Fun stuff...)

All the best,
Javier Ruiz

I am in awe of such technical expertise and fluency of patois. I  
must admit, I understand absolutely nothing (except individual  
words, for the most part) of the above paragraph.  It reminds me of  
one of my favorite Charlie Brown cartoons, in which Charlie, Lucy  
and the piano player (Can't remember his name at the moment) are  
lying on their backs staring at clouds passing overhead. Lucy says  
something like, Ah yes, I see the Reformation struggle of  
Christianity, the next one observes, For me, the shapes represent  
a typical Rorschach test, and Charlie thinks (in the bubble), I  
was going to say I thought I saw a lamb and a doggie, but I'm going  
to keep it to myself.


Count me in on the Charlie side.

Cheers,

Dean
