Hi, New here.
As the Perl 24to12 is un-reachable, and I can't get the Java one working.
I've recreated it using some code from the C in this list.
It can be found at:
As I had to use Gimp to scale and pad the images then ImageMagick to convert to raw 24bit Then use this to convert to JuiceBox Picture.
I wrote a more advanced converter:
You need the perl::imager library to use it.
But it will convert paletted to rgb if necessary, rotate it necessary, scale then pad as required, then convert to .jbp
takes two filenames. picture.in and picture.jbp
Could be improved, but it works.
