SaveJpeg quality override? Size increase?

Mar 16, 2012 at 1:44 AM

Hi, I have this concern... (it applies to WriteableBitmap in general)

If I load and edit and image which original quality is 80 and then do SaveJpeg() with quality 100 it will increase in size, but obviously won't improve in quality (its capped by its original 80 quality definition).

So some questions...

1) Is it possible to get an image originals quality?

2) If I'm finally able to get the initial quality (80) and then I perform a SaveJpeg() with quality 80, will final quality be 64? (80 x 0.8)

The egg or the chicken?
