ΓòÉΓòÉΓòÉ 2. Known Problems ΓòÉΓòÉΓòÉ
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.
ΓòÉΓòÉΓòÉ 3. JPEG ΓòÉΓòÉΓòÉ
Joint Photographic Experts Group (JPEG) refers to a still-picture compression
standard that specifies several modes of operation. The mode used by the
Independent JPEG Group's(IJPEG) software, which is incorporated into PMJPEG, is
sequential buildup; in this mode, each component of an image is encoded in a
left-to-right and top-to-bottom scan. Sequential mode is lossy, which means
that when you compress an image, you will lose information. That is, when you
decode the compressed image, the decoded image will not exactly match the
original. One reason that sequential mode JPEG is lossy is that the algorithm
compresses an image by removing visually insignificant information, colors that
the human eye cannot detect.
ΓòÉΓòÉΓòÉ 4. Converting File Formats with PMJPEG ΓòÉΓòÉΓòÉ
Images can be converted from one file format to another by loading an image
with the File Open menu item and saving it to the desired file format with the
File Save menu item.
Before you load an image that you want to convert, you should check the Maximum
Color Depth option. This option determines the maximum number of colors in a
displayed image. Even though an image may look good, there may have been a
loss of colors and data in the image. For example, suppose you are viewing a
24-bit image with Maximum Color Depth set to 256 colors. The 24-bit image can
have up to 16.7 million colors but the number of colors in the image is reduced
to 256 when it is loaded. When you save this image to a different format, you
lose many colors that were in the original image. To avoid losing colors in
the image, you should set Maximum Color Depth to 16.7 million colors before
loading the image.
PMJPEG saves a displayed image to a specified file format with 8-bits per pixel
or 24-bits per pixel. Images stored with 1, 2, or 4-bits per pixel are
converted to 8-bits per pixel and can be saved in this format only. Images
with 8 or 24-bits per pixel are saved with 8 or 24-bits per pixel,
respectively. The two exceptions to the color depth of the saved file format
are the JPEG file format which is always 24-bits per pixel and the GIF format
which is 8-bits per pixel.
Batch Compression of images to JPEG is not affected by the Maximum Color Depth
option.
If you are creating a bitmap to be used as an OS/2 desktop-background image,
apply the Map to System Colors function to a displayed image before saving it
to an OS/2 BMP file. If you are converting a 24-bit image to an OS/2 BMP, you
should set Maximum Color Depth to 16.7 million colors before you load the
image. This produces a better looking background image than one created by
loading a 24-bit image with a Maximum Color Depth of 256 colors and then
applying the Map to System Colors function.
ΓòÉΓòÉΓòÉ 5. Starting a Slideshow from the Command Line ΓòÉΓòÉΓòÉ
A slideshow can be initiated from the OS/2 command line by executing the
following at the OS/2 prompt:
pmjpeg [filename 1] [filename 2] [filename 3] ... [filename n]
The files are displayed in the order in which they are entered on the command
line. Also, the slideshow options that were saved by the Save All Options menu
item are used. If no options were saved, the default slideshow options are
used. There is no limit to the number of files that you enter. The only
restrictions are the number of characters that you can fit in one command at
the OS/2 prompt.
For example, if you wanted to display the files, "colrtest.jpg", "mirri3.jpg",
and "image1.gif", in the order listed , type
pmjpeg colrtest.jpg mirri3.jpg image1.gif
This example assumes that PMJPEG is in your search path and this command is
executed in the directory containing the images. If OS/2 can't find
"pmjpeg.exe" or the images, you can prefix "pmjpeg.exe" or the images with a
standard OS/2 path.
ΓòÉΓòÉΓòÉ 6. Image File Formats ΓòÉΓòÉΓòÉ
o JPEG File Formats
o TIFF
o Graphics Interchange Format (GIF)
o Targa
o PCX
o BMP
ΓòÉΓòÉΓòÉ 6.1. JPEG File Formats ΓòÉΓòÉΓòÉ
The JPEG committee has not specified a standard file format, and consequently,
many applications of the JPEG algorithm use their own proprietary format.
PMJPEG uses the JPEG File Interchange Format(JFIF) which transports only pixel
information. JFIF is supported by the IJPEG Group's software and other
programs based on their code.
Handmade Software's GIF2JPG and Image Alchemy use a proprietary JPEG format
that is not compatible with the JFIF standard. This proprietary format is not
supported by PMJPEG. When you use GIF2JPG v.2.0, remember to leave out the
"-s" option to produce a JPEG file that is compatible with the JFIF standard
and viewable with PMJPEG.
ΓòÉΓòÉΓòÉ 6.2. Graphics Interchange Format (GIF) ΓòÉΓòÉΓòÉ
PMJPEG can view interlaced/non-interlaced GIF87a and GIF89a files, and it can
save non-interlaced GIF87a files. If a GIF89a file contains more than one
image, it will display the first image in the file.
ΓòÉΓòÉΓòÉ 6.3. Targa ΓòÉΓòÉΓòÉ
PMJPEG can view uncompressed or run-length encoded TARGA files stored with 8,
15, 16, 24, or 32 bits per pixel and it can save uncompressed TARGA files with
8 or 24 bits per pixel.
ΓòÉΓòÉΓòÉ 6.4. PCX ΓòÉΓòÉΓòÉ
PMJPEG can view PCX files stored with 1, 4, 8, or 24 bits per pixel. If a 1,
4, or 8 bits per pixel PCX file does not have a valid palette, PMJPEG will use
a default palette. It can save PCX Version 5.0 files with 8 or 24 bits per
pixel.
ΓòÉΓòÉΓòÉ 6.5. BMP ΓòÉΓòÉΓòÉ
PMJPEG can view Windows and OS/2 (1.x and 2.0) BMP files stored with 1, 4, 8,
or 24 bits per pixel and can view BMP files that are run-length encoded(RLE).
In addition, it can display the first image in an OS/2 bitmap array. It can
save uncompressed Windows or OS/2 BMP files in 8 or 24 bits per pixel and can
save BMP files with RLE.
Note that some graphics viewers use the file extension ".RLE" for run-length
encoded Windows BMP files. PMJPEG uses the ".BMP" extension as a default for
such files.
ΓòÉΓòÉΓòÉ 6.6. Tagged Interchange File Format (TIFF) ΓòÉΓòÉΓòÉ
PMJPEG supports a subset of the TIFF 6.0 specification. PMJPEG can view TIFF
files stored with 1, 2, 4, 8, or 24 bits per pixel. PMJPEG can read TIFF
images stored in strip format, in which the image is divided into horizontal
strips of pixels, and tile format, in which an image is divided into
rectangular grids of pixels. The compression modes LZW, Packbits, Thunderscan,
NeXT, and CCITT (RLE, RLEW, FAX3, FAX4) can be read as well as uncompressed
TIFF images.
PMJPEG can save uncompressed or LZW compressed TIFF files with 8 or 24 bits per
pixel. TIFF files are saved in strip format.
ΓòÉΓòÉΓòÉ 7. Menu Commands ΓòÉΓòÉΓòÉ
The menus are ordered by the following main topics:
o File Menu
o Edit Menu
o Options
ΓòÉΓòÉΓòÉ 7.1. File Menu ΓòÉΓòÉΓòÉ

ΓòÉΓòÉΓòÉ 7.1.3. Save All Options ΓòÉΓòÉΓòÉ
This will save all the PMJPEG options to a file named "pmjpeg.sav" in the same
directory as the PMJPEG executable. When PMJPEG is initially loaded, the
options will be loaded if "pmjpeg.sav" exists.
ΓòÉΓòÉΓòÉ 7.1.4. Delete ΓòÉΓòÉΓòÉ
This menu command lets you delete the file containing the currently displayed
image. PMJPEG will prompt you for confirmation before deleting the file.
ΓòÉΓòÉΓòÉ 7.1.5. Batch Compression ΓòÉΓòÉΓòÉ
Select GIF, TIFF, and TARGA files to compress to JPEG format with the options
specified in the JPEG Options dialog. The list boxes in the left column
display the drives and the directories in the current path, the list box in the
middle displays the files in the current path, and the one in the right
displays a list of files to be converted. To add file(s) to the "Files
Selected" box, select the file(s) you want to convert and press the "Add"
button. To remove file(s) from this box, select the file(s) in this box and
press the "Remove" button.
The output file(s) will have the same name as the input file(s) except that
they will have a ".jpg" extension. Also, the output file(s) will be placed in
the same directory path in which the input file(s) were located.
See also JPEG Options.
ΓòÉΓòÉΓòÉ 7.1.6. Slideshow ΓòÉΓòÉΓòÉ
Select the JPEG, TIFF, GIF, Targa, and BMP files to display in a slideshow.
The order in which you add the files will be the order in which they are
displayed.
After a picture is loaded and displayed, if Automatic Slide Advancement is
selected, there will be a user-selected delay before the next picture is
loaded. To advance to the next picture before the delay has elapsed, click on
the window with the right mouse button. If Manual Slide Advancement is
selected, PMJPEG will wait until you click with the right mouse button before
advancing to the next picture.
If you would like the slideshow to continue from the beginning of the list
after the last picture is displayed, check off the Cycle Slideshow menu option.
To abort the slideshow, click on the window with the left mouse button, click
on the "Yes" button in the confirmation dialog, and the slideshow will stop
after the currently loading picture is displayed.
See also Slideshow Options.
ΓòÉΓòÉΓòÉ 7.1.7. Print ΓòÉΓòÉΓòÉ
Print the image currently displayed.
ΓòÉΓòÉΓòÉ 7.1.8. Print Setup ΓòÉΓòÉΓòÉ
The Print Setup dialog box lets you select the Printer and Job Properties. The
Job Properties dialog box allows printer driver-dependent options to be
changed.
ΓòÉΓòÉΓòÉ 7.1.9. Print Options ΓòÉΓòÉΓòÉ
The displayed image can be printed in three ways: 1) best fit for the page, 2)
fit for the full page, or 3) scaled by a user-selected factor. Best Fit scales
the image for maximum fit on a printed page while maintaining the image's
aspect ratio. Fit for Full Page scales the image such that it fits the entire
page. The Scale option scales the printed image's width or height by an integer
factor that is selected by the user.
ΓòÉΓòÉΓòÉ 7.1.10. Exit ΓòÉΓòÉΓòÉ
Exit from PMJPEG.
ΓòÉΓòÉΓòÉ 7.2. Edit Menu ΓòÉΓòÉΓòÉ
The Edit menu includes commands that enable you to transfer images to and from
the clipboard, change the color components of an image, and to manipulate the
image.
o Copy
o Paste
o Crop
o HSV Adjustment
o Color Balance
o Contrast Enhancement
o Grayscale
o Gamma Correction
o Map To System Colors
o Rotate
o Flip Horizontal
o Flip Vertical
o Resize
ΓòÉΓòÉΓòÉ 7.2.1. Copy ΓòÉΓòÉΓòÉ
Copy the entire image to the clipboard.
ΓòÉΓòÉΓòÉ 7.2.2. Paste ΓòÉΓòÉΓòÉ
Paste an image from the clipboard.
ΓòÉΓòÉΓòÉ 7.2.3. Crop ΓòÉΓòÉΓòÉ
If a region of the image is selected (see Selecting a Region to Crop), keep
that region and discard the image outside of the selected region.
ΓòÉΓòÉΓòÉ 7.2.4. HSV Adjustment ΓòÉΓòÉΓòÉ
Use the scroll bars to adjust the amount of hue, saturation, and
value/brightness in an image. A value of 0 on the scroll bar means that there
is no change in the corresponding color component. When the value is increased
or decreased, the color component is increased or decreased, respectively.
ΓòÉΓòÉΓòÉ 7.2.5. Color Balance ΓòÉΓòÉΓòÉ
Use the scroll bars to adjust the amount of red, green, and blue in an image.
A value of 0 on the scroll bar means that there is no change in the
corresponding color component. When the value is increased or decreased, the
color component is increased or decreased, respectively.
ΓòÉΓòÉΓòÉ 7.2.6. Contrast Enhancement ΓòÉΓòÉΓòÉ
Use the scroll bar to adjust the amount of contrast in an image. A value of 0
on the scroll bar means that there is no change in the contrast. When the
value is increased or decreased, the contrast is increased or decreased,
respectively.
ΓòÉΓòÉΓòÉ 7.2.7. Grayscale ΓòÉΓòÉΓòÉ
Convert a color image into a grayscale one.
ΓòÉΓòÉΓòÉ 7.2.8. Gamma Correction ΓòÉΓòÉΓòÉ
Use the scroll bar to adjust the amount of gamma. A value of 1.0 on the scroll
bar means that there is no change in the image. In general, increasing the
gamma makes the image lighter and decreasing it makes the image darker. A
gamma of 2.2 is a commonly used value.
ΓòÉΓòÉΓòÉ 7.2.9. Map To System Colors ΓòÉΓòÉΓòÉ
Converts the displayed image to an image that has a 256-color palette
containing the system colors of the OS/2 desktop. Use this option to generate
an image that can be used as a 256-color OS/2 desktop-background image.
ΓòÉΓòÉΓòÉ 7.2.10. Rotate ΓòÉΓòÉΓòÉ
Rotate the image clockwise by 90 degrees.
ΓòÉΓòÉΓòÉ 7.2.11. Flip Horizontal ΓòÉΓòÉΓòÉ
Flip the image around the vertical axis.
ΓòÉΓòÉΓòÉ 7.2.12. Flip Vertical ΓòÉΓòÉΓòÉ
Flip the image around the horizontal axis.
ΓòÉΓòÉΓòÉ 7.2.13. Resize ΓòÉΓòÉΓòÉ
Change the spatial resolution of the displayed image. Common sizes such as
640x680, 800x600, 1024x768, and 1280x1024 can be easily selected.
The Maximize Fit on Desktop option will resize the image into the largest
possible window that will fit on the desktop while keeping the aspect ratio,
the ratio between the original width and height.
Also, a custom size can be manually entered. If Keep Aspect Ratio is enabled,
only one dimension needs to be entered because the other one is automatically
changed to maintain the aspect ratio.
ΓòÉΓòÉΓòÉ 7.3. Options Menu ΓòÉΓòÉΓòÉ
The Options menu includes commands that let you determine how other commands
operate. The settings for the options can be saved with the Save All Options
command.
o Stretch to Fit Window
o View Fullscreen
o Maximum Color Depth
o Display Old Image during Load
o Move Window after Load
o Auto-Refresh
o JPEG Options
o Slideshow Options
ΓòÉΓòÉΓòÉ 7.3.1. Stretch to Fit Window ΓòÉΓòÉΓòÉ
When this option is checked, the scrollbars for the PMJPEG window are turned
off and the image is stretched to the dimensions of the client area of the
PMJPEG window. This option does not permanently change the resolution of the
image. If you save the image, the original image is saved, not the stretched
one.
ΓòÉΓòÉΓòÉ 7.3.2. View Fullscreen ΓòÉΓòÉΓòÉ
View the currently displayed image with the full screen. If the image is
larger than the entire screen, the image will be resized with the best
proportional fit before it is displayed. If the image is smaller, it will be
displayed in the center of the screen. To exit from full screen mode, press
any key or click on the screen with the left mouse button.
ΓòÉΓòÉΓòÉ 7.3.3. Maximum Color Depth ΓòÉΓòÉΓòÉ
When you load an image that has more colors than the Maximum Color Depth
setting, PMJPEG will reduce the number of colors to the Maximum Color Depth
setting before displaying the image. If you are viewing images, you should set
this option to the number of colors supported by your display driver. If you
are converting images from one file format to another, you should set it to
16.7 million colors.
ΓòÉΓòÉΓòÉ 7.3.4. Display Old Image during Load ΓòÉΓòÉΓòÉ
If this option is checked, you can continue viewing the currently displayed
image while another image is being loaded. However, this option will use more
memory because PMJPEG has to maintain two images. Consequently, it may slow
down the loading of the next image if PMJPEG runs out of physical memory and
must use slower virtual memory.
ΓòÉΓòÉΓòÉ 7.3.5. Move Image after Load ΓòÉΓòÉΓòÉ
If this option is checked, the PMJPEG window is moved to the upper left-hand
corner of the desktop after an image is loaded.
ΓòÉΓòÉΓòÉ 7.3.6. Auto-Refresh ΓòÉΓòÉΓòÉ
The purpose of this option is to provide a temporary solution to a bug in the
256 color drivers. This bug is evident when the area of the image under a
drop-down menu or under a dialog box is not properly redrawn after the
drop-down menu or the dialog, respectively, is closed.
If this menu item is checked, PMJPEG will automatically refresh the image when
it is necessary.
ΓòÉΓòÉΓòÉ 7.3.7. JPEG Options ΓòÉΓòÉΓòÉ
2-pass(Heckbert) quantization produces better looking output than 1-pass
quantization and it is slower. Also, 2-pass quantization uses more memory so
it may be even slower because PMJPEG will swap to hard disk when it runs out of
virtual memory. The output of 1-pass generally looks more grainy.
Dithering uses available colors in a palette to simulate additional colors.
The dithering method that PMJPEG uses is called Floyd-Steinberg Dithering.
Dithering is useful when quantizing to 256 colors or less but it is not needed
for a true-color (24-bit) display. You may want to turn off dithering since it
sometimes causes a grainy output image.
The Quality Factor, an integer between 0 and 100 inclusive, determines the
tradeoff between the output file size and the output image quality. If you
choose a high quality factor, the image quality will be high but the file size
will be large. A lower quality setting will yield a smaller file at a cost of
lower fidelity. Since the JPEG algorithm is lossy, a quality factor of 100
will not give you a losslessly compressed image.
The Smoothing Factor, also an integer between 0 and 100 inclusive, determines
the degree of smoothing to apply to an image before compressing that image with
JPEG. The higher you set the factor, the higher the degree of smoothing that
is applied. A smoothing factor of 0 means that no smoothing is performed.
Smoothing removes noise introduced when an image is dithered, and, in turn,
smoothing produces a smaller JPEG file. It should be used for only dithered
images, like photographic GIF pictures. Generally, a factor between 10 and 50
removes the dithering noise from an image.
Entropy Optimization produces a smaller JPEG file but it takes more time to
encode the image.
If PMJPEG runs out of virtual memory while it is decoding/encoding JPEG files,
it will use temporary files that are created in the specified path.
ΓòÉΓòÉΓòÉ 7.3.8. Slideshow Options ΓòÉΓòÉΓòÉ
When a slideshow is running, the Cycle Slideshow option determines whether or
not a list of images are continuously displayed in a cycle. If this option is
on, the slideshow returns back to the first picture after the last one is
displayed and continues to display all the images in a selected list until you
abort the slideshow.
The Fullscreen option lets you display the images in the slideshow with the
full screen as described in the View Fullscreen section.
The Slide Advancement options determine how to advance to the next image in a
slideshow. In Manual mode, PMJPEG will wait until you click with the right
mouse button before advancing to the next picture. In Automatic mode, there
will be a user-selected time delay before the next picture is loaded. To
advance to the next picture before the delay has elapsed, click on the window
with the right mouse button. The Delay can be set to a value between 0 and 999
seconds.
The Buffer Image Formats options allow buffering of selected image formats
during a cyclic slideshow. If a type is selected, all images of that type are
stored in memory after they are loaded and decompressed, and they will not be
loaded/decompressed the next time they are displayed. This feature must be
used in conjunction with the Cycle Slideshow option. Buffering images can use
a lot of memory; if you don't have much physical memory, be certain that there
is enough disk space on OS/2's swap drive to handle this memory usage.
ΓòÉΓòÉΓòÉ 7.3.9. Progress Options ΓòÉΓòÉΓòÉ
For time-consuming tasks like loading, saving, batch compressing, and mapping
to system colors, PMJPEG displays a percentage that indicates how much of the
task has been completed. The progress can be displayed in either a dialog box
or the title bar of the PMJPEG window.
ΓòÉΓòÉΓòÉ 8. Selecting a Region to Crop ΓòÉΓòÉΓòÉ
To select a region of the image, click on the image with the left mouse button.
While holding down that button, move your mouse until the rectangle surrounds
the desired region, and then release the mouse button. The dimensions of the
selected region are displayed in the center of the indicated region.
ΓòÉΓòÉΓòÉ 9. How to Register ΓòÉΓòÉΓòÉ
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 $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.
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.1.4. 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 form and send a check in US funds drawn on a US
bank 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.
ΓòÉΓòÉΓòÉ 10. Reporting Bugs ΓòÉΓòÉΓòÉ
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:
