INTRODUCTION
PMJPEG is a shareware image viewer with image processing and conversion
capabilities for OS/2 2.x. PMJPEG is a port of WinJPEG to OS/2 2.x.
PMJPEG v.1.31 has the following features:
- display JPEG, TIFF, Targa, GIF, PCX, Windows BMP, or OS/2 BMP images
- export an image to JPEG, TIFF, Targa, GIF, PCX, or OS/2 BMP
- capability of generating 256-color OS/2 desktop-background bitmaps
that use the desktop's system colors
- display of 24-bit images with 1-pass or 2-pass(for JPEG only)
quantization and Floyd-Steinberg dithering
- color balance: red, green, and blue adjustment
- hue, saturation, and brightness adjustment
- contrast enhancement
- image rotation, vertical or horizontal flip, and image resizing
- image cropping
- batch file compression of GIF, TIFF, or TARGA files to JPEG File
Interchange Format (JFIF)
- copy an image to the clipboard
- paste an image from the clipboard
- slideshow: display selected files sequentially with a cycle option
- image buffering in a cyclic slideshow
- support for file name extension association and starting a slideshow
from the command line
In order to see images displayed with the right colors, you must use a
version of OS/2 and a 256 color driver that support palette manager.
Both OS/2 2.0 with the Service Pack and OS/2 2.1 beta support palette
manager.
If you are using the 256 color ET4000 driver that comes with OS/2 2.1
beta, you'll notice that the image under the dialog box or under the
drop-down menu is not re-drawn correctly. This is a bug in the ET4000
driver. Use the Auto-Refresh option if you have this problem.
When you exit, the system colors may not return to normal. This appears
to be a bug with the palette manager of the December 1992 OS/2 2.1 beta.
However, the palette does appear to correct itself after you open and/or
close a window, such as the window list.

1) The distributed archive must contain ONLY the files listed above.
2) The contents of this archive are NOT MODIFIED in any way.
3) This version is not to be sold. However, a reasonable disk copying fee
is permitted.
4) This version is not to be bundled with a commercially sold package

HOW TO REGISTER
If you use PMJPEG for more than 14 days, you are expected to register
PMJPEG. When you register, you will receive the latest version of
PMJPEG, a user manual, and a collection of JPEG images (we will put as
many as we can fit on 2 720k 3 1/2" floppies, on 1 1.44M
3 1/2" floppy, or on 4 360k 5 1/4" floppies). Also, the registered
version does not have the reminder-to-register screen at the start.
The registration fee is only $20. MA residents, add 5% sales tax to the
registration fee. US residents, add $3 for shipping and handling;
non-US residents, add $8 for shipping and handling. If you want PMJPEG
e-mailed to your account instead of having it physically mailed to you,
there is no extra shipping charge.
Updates are free but the shipping charge described above applies to updates.
Users who register PMJPEG and provide an e-mail address will automatically
receive updates via e-mail.
For e-mail registrations, you need to use a program called "uudecode" to
decode the uuencoded file that we e-mail to you. For your information,
a uuencoded file is a binary file that is converted to text by a program
called "uuencode". If your mail system rejects large messages, we will
split the uuencoded file into smaller parts before mailing the parts to
you, and you will need to edit the messages with a text editor before
you can decode them. Compuserve, for example, does not permit large
e-mail messages. Also, the uuencoded file is rather large; it is
approximately 300k for PMJPEG v.1.31. Compuserve users may find it less
expensive to receive PMJPEG via U.S. Mail.
Registrations with the incorrect fee or with non-US currency will be
returned.
To register, complete the order form and send a check in US funds to:
Norman Yee
58 Chandler St.
Boston, MA 02116
Registration of PMJPEG is based on "personal usage." Corporate or
organizational users must register all copies used on an individual
basis; a specific person (name) must be explicitly assigned to each
registrant who will be provided with a personalized copy of PMJPEG.
Registration grants a specific person (not an organization or
corporate entity) the right to use PMJPEG.
Although we will try to mail your copy of PMJPEG 1-3 weeks after
we receive your registration, please allow up to 4-6 weeks for
delivery.
