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. It is
a native 32-bit PM application.
PMJPEG v.1.63 has the following features:
- display JPEG, TIFF, GIF, Targa, PCX, Windows BMP, OS/2 BMP, or PPM images
- export an image to JPEG, TIFF, GIF, Targa, PCX, Windows BMP, OS/2 BMP,
or PPM format
- capability of generating OS/2 desktop-background bitmaps that use
the system colors
- display an image in monochrome, 16 color, 256 color, hicolor, or
truecolor display modes
- display an image in full screen mode
- print an image with scaling, best proportional fit on the page, or
fit for full page
- red/green/blue or hue/saturation/brightness adjustment
- color to grayscale conversion or image negative conversion
- contrast enhancement
- gamma correction
- image rotation, vertical or horizontal flip, image resizing, and
- batch file compression of GIF, TIFF, Targa, or PPM files to JPEG File Interchange Format
- copy an image to the clipboard or paste an image from the clipboard
- slideshow: display selected files in forward, reverse, or random
order with a cycle option
- image buffering in a cyclic slideshow
- capture a window, the client area of a window, or a portion of or
the entire desktop
- support for file name extension association and starting a slideshow
from the command line

There are two bugs in the 256 color ET4000 driver that comes with the
OS/2 2.1 beta or OS/2 2.0 + Service Pack: 1) the driver does not stretch
the bitmap correctly so the Stretch to Fit Window option does not work
properly, and 2) the image under the dialog box or under the drop-down
menu is not re-drawn with the right colors. Use the Auto-Refresh option
if you have the second problem.
If you are using the 256 color ET4000 driver, for certain images such as
24-bit images displayed with Maximum Color Depth set to 256 colors, the
text that shows the cropping dimensions is garbled by a filled box.
This appears to be a bug in OS/2's palette manager or the driver.
If you are using a 256 color driver, when you exit PMJPEG, the system
colors do not immediately return to normal. The system colors are
gradually restored by OS/2. You can force the colors to change back by
opening and/or closing a window, such as the window list that pops up
when you hit CTL-ESC.
You are free to distribute this shareware version of PMJPEG as long as the
following conditions are met:
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
4) This version is not to be bundled with a commercially sold package
without permission from the authors.
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 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. Massachusetts residents, add 5% sales
tax to the registration fee. US residents, add $4 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. If you are paying
with a Visa or MasterCard, add 10% to this subtotal. The 10% is the
processing fee that we get charged for credit card transactions.
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.1.6. Compuserve users may find it less
expensive to receive PMJPEG via U.S. Mail.
Registrations with the incorrect fee, non-US currency, or drawn on a
non-US bank will be returned.
To register, complete the order and send payment to:
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.
If you find a bug in PMJPEG, we would appreciate it if you would inform
us of the bug through one of our e-mail accounts:
When you send us a bug report, include a description of the procedure
for reproducing the bug and a description of your system
configuration(hardware and software).
