Documentation for VIEW.EXE, version 1.54
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
VIEW [filename|filespec] [options]
VIEW can read faxes stored in ZFAX version 2 (1D-MH only), QuickLink II
QFX format, or TIFF-Class-F format (Faxworks). It can print these faxes
also.
The default filespec is "*.??X" which nicely handles *.FAX, *.QFX, *.PCX,
and *.DCX. If you specify a filename rather than a filespec, VIEW works
in batch mode rather than menu mode. (See notes on BATCH mode at the end
of this document.)
To use VIEW, change into the directory where all your faxes are located,
and then start it, by typing "VIEW". If if finds any faxes, it will bring
up a list of them on the screen, and you can use the up and down arrows to
select which fax you wish to view or print.
The available commands are listed on the bottom of the screen...
<Enter>=view, <Ctrl-Enter>=print, <F2>=convert to PCX, <F3>=convert to DCX,
and <Delete>=delete the fax
If you start VIEW without any command line parameters, it will automatically
detect either a CGA, EGA, or VGA display. However, it will not detect the
printer type, so you will have to specify that manually.
To force a specific video mode when starting VIEW...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mode Resolution
---- ----------
VIEW /CGA $6 640x200
VIEW /EGA $10 640x350
VIEW /VGA $11 640x480
VIEW /800 (or VIEW /SVGA) $102 800x600
VIEW /1024 $104 1024x768
VIEW /1280 $106 1280x1024
Your video card and/or monitor may not be able to support all of the modes
available.
Commands available while viewing the fax itself
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When the fax image is on the screen, you have a few choices...
Alt-I invert the fax colors (black becomes white, white becomes black)
Alt-F flip the fax for thoese people that send you upside down faxes
Alt-S shrink the fax so that the image isn't quite so big on the screen
You can pan around by using the up, down, left, and right arrow keys.
To go to the next page in a fax, <PgDn>, the previous page <PgUp>
To use a specific printer driver when starting VIEW...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Switch DPI Printer
------ ------- -------------
VIEW /P24 180x180 Epson compatible 24-pin dot matrix
VIEW /P25 360x180 Epson compatible 24-pin dot matrix
VIEW /P26 180x180 Canon BJ-200 compatible bubble-jet printer
VIEW /P27 360x360 Canon BJ-200 compatible bubble-jet printer
VIEW /P37 150x150 PCL level 3 compatible laser printer
VIEW /P38 150x150 PCL level 4 compatible laser printer (faster than PCL3)
VIEW /P39 150x150 PCL level 5 compatible laser printer (faster than PCL4)
VIEW /P40 300x300 PCL level 3 compatible laser printer
VIEW /P41 300x300 PCL level 4 compatible laser printer (faster than PCL3)
VIEW /P42 300x300 PCL level 5 compatible laser printer (faster than PCL4)
VIEW /P24 is recommened for most dot matrix printers, and /P40 is recommened
for most lasers if you do not know what PCL level it supports.
*** What about printing to ports other than LPT1 ???
VIEW /P40:LPT2
Will print to a laser printer on LPT2 as a software interrupt 17 device.
(Should use this.)
VIEW /P40:+LPT2
Will print to a laser printer on LPT2 as a "file" rather than a device.
(Sometimes this prints a little faster, but usually it prints much slower.)
VIEW /P40:+TEST.PRN
then from a DOS prompt, "copy test.prn lpt2" as an alternate way of printing
*** What about A4 or US-Legal paper sizes?
VIEW /P40 /A4 for metric-A4 (rather than US-letter)
VIEW /P40 /LP for US-legal (rather than US-letter)
Miscellaneous switches
~~~~~~~~~~~~~~~~~~~~~~
VIEW /DB Try to display bad scan lines (normally, VIEW just puts a dotted
line across the screen if it detects a bad scan line.)
VIEW /BO Display fax using a backwards bit order. This may be necessary
if you have received a fax on a USR modem with Binkley's internal
fax routines, or if you have started BGFAX with the incorrect
command line switch.
Multiple command lines parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
VIEW /p40 /1024
For example would make VIEW use 1024x768 resolution when viewing faxes and
print faxes (when the user hits Ctrl-Enter) to a laser printer. It is
suggested that you make a batch file to call VIEW with these parameters so
that you don't have to always type them in.
BATCH MODE
~~~~~~~~~~
You can also start VIEW in a "batch" mode, which requires no user
intervention.
"VIEW FAX0001.FAX /P40" would print the fax0001.fax file to a laser printer.
"VIEW fax0001.fax /dcx" would convert that fax to a DCX file
"VIEW fax0001.fax /pcx" would convert that fax to PCX files
(Note that a DCX file is basically a multipage PCX file, and many fax
applications support the DCX format. PCX format gets messy because each
fax page has to be saved into a seperate file, but PCX format is nearly
universal and just about every graphics program on the planet will let
you load a PCX image.)
Note about 2D-MR compressed faxes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
VIEW does not currently support 2D-MR faxes properly. A 2D-MR fax is
basically a 1D-MH normal fax with every other line having only "difference"
information rather than the whole scan line encoded. VIEW will correctly
view the 1D-MH lines, but will show the 2D-MR lines as improperly decoded
scan lines.
