I have the same requirement. I'm a little embarrassed to admit that I
did it with the following GIMP script:
(define
(thumbnail filename tfilename)
(let
(
(image (car (file-jpeg-load 0 filename filename)))
)
(let
(
(width (car (gimp-image-width image)))
(height (car (gimp-image-height image)))
)
(let
(
(scale (sqrt (/ 19200 (* width
height))))
)
(gimp-image-scale image (* width scale)
(* height scale))
(file-jpeg-save 1 image 2 tfilename
tfilename 1 0 1)
)
)
)
)
Where 19200 is the number of pixels in the thumbnail, regardless of the
actual size or aspect ratio of the original. This could have been made a
parameter, now that I think about it.
If you find Java code to do the same, I'd be most interested to hear.
