Well... I don't speak French either, but since telling you what it says only
requires _reading_ French, I'll be happy to oblige. This translation is
rather
literal -- i.e., not in the best English idiom.

This library is a simple binding for the reading of Jpeg files.

This library permits:
  a.. The Reading of JPEG files, with specification of the reading
parameters (notably, the utilization of the parameter Scale, permitting the
reading of a JPEG file in reducing significantly the size of the images ???
(1/2, 1/4, 1/8).  This function also permits the creation of little images
with great performance. (The reduction to 1/8 of an image of 100K takes 0.07
seconds on a 466 Mhz Celeron.
  b.. The writing of JPEG files, either from another file, or from data in
memory.
Novelties
