------------------------
What Does It Do?
===============
JPEG_+_Comment is an ARexx script for use with ADPro 2.5 that searches for
and displays any text comments contained in a JPEG file, then loads the file
into ADPro's image buffer.
NOTE: JPEG_+_Comment will only search for comments in JFIF JPEG files, as
this is the only type of JPEG file that it was designed to recognize. This
limitation is due to the fact that I have no information on the other
varieties (HSI JPEGs, TIFF JPEGs, PICT JPEGs, & others?) of JPEGs. It
wouldn't make much sense to add support for any of those types but HSI,
since the ADPro JPEG Loader only supports JFIF and HSI JPEGS.
------------------------
Requirements
============
1. ARexx
2. Art Department Professional version 2.5
3. ADPro JPEG Loader
------------------------
Installation
============
Copy JPEG_+_Comment to your ADPro:Loaders2 directory or elsewhere.
------------------------
Using it
========
Start JPEG_+_Comment using the instructions for launching ARexx scripts in
your ADPro manual, or any other method you can think of.
Once it starts, you will see a requester with the words "Smoothing Off" and
three buttons. The right button (Cancel) aborts the script. The middle
button changes the Smoothing status of the JPEG Loader as shown in the
requester. The left button (OK) accepts the Smoothing status and displays a
file requester from which to pick a JPEG file to load.
If the file you pick is a JPEG file, a small window will open showing the
following:
File: <the JPEG file you selected>
Smoothing: <the Smoothing status of the JPEG Loader>
Searching for comments...
Ctrl-d to stop
JPEG_+_Comment is now searching the selected file for comments. If you
press Ctrl-d (the "Ctrl" key and the "d" key at the same time) while this
window is open, JPEG_+_Comment will stop searching for comments and go on to
the rest of the script. Pressing Ctrl-c while this window is open will
abort the script.
If you stop the search before any comments are found, or if no comments are
found, JPEG_+_Comment will load the selected file into ADPro's image buffer.
If JPEG_+_Comment is able to find comments, a large window will open showing
the following:
File: <the JPEG file you selected>
Smoothing: <the Smoothing status of the JPEG Loader>
Comment <number>: <Comment>
After this window opens, JPEG_+_Comment will load the selected file into
ADPro's image buffer. The window will remain open until you click on its
close gadget.

Contacting the Author
=====================
If you have any bug reports, questions, suggestions, comments, or gifts to
send me or if you would like information about the most recent versions of
my programs, I would be glad to hear from you. I would particularly like to
hear from you if:
1. You come across a JPEG file that you know contains comments but
JPEG_+_Comment does not recognize it as a JPEG file or does not display
the comments. If this occurs, I would appreciate it if you sent me a copy
of the file so that I could try to fix the problem.
2. You have any information relating to:
a. JPEG file comments (programs that let you add/edit them, etc.)
b. the various JPEG file formats (the structure of JPEG files, what JPEG
file formats can contain comments, etc.)
