ExtractJPEGs does exactly what its name says: it extracts JPEG pictures
from a given file. For instance,  some Quicktime movies consist of JPEG
pictures.


USAGE
-----
ExtractJPEGs must be launched from CLI.
syntax:

ExtractJPEGs <file>

simple, eh?

Example -  You want to get all  frames out  of the  "Starship Troopers"
trailer:

ExtractJPEGs strshptroopers.mov


WHAT IT DOES
------------
ExtractJPEGs hunts for JPEG pictures in the given file and writes them
into the current directory (0.jpg, 1.jpg, 2.jpg, ...).

You might use the programs freplace and fixsuffix to convert the file-
names, e.g.:

----------------------------------------------------------------------
freplace .jpg ""
; "0.jpg" --> "0", "1.jpg" --> "1" etc.

list #? LFORMAT "rename %N frame.%N" >t:script
; "0" --> "frame.0"

sort t:script t:script
; optional

execute t:script

list frame.(?|??|???) LFORMAT "fixsuffix %N 4" >t:script
; "frame.0" --> "frame.0000"

sort t:script t:script
; optional

execute t:script
----------------------------------------------------------------------
