JPG.VIEW.SHK is a ShrinkIt archive. Use ShrinkIt GS v1.1 to unshrink the
archive. The archive unshrinks to a GS/OS desktop application named JPEG View
The program is a display utility application of a pre-release grayscale JPEG
decompress and display utility. JPEG View GS can view a standard JPG, JPEG or
JFIF graphic file (all display the same).

This is the only pre-release version currently made available to the public of
such a JPEG display program and does not allow saving of the displayed grayscale
JPEG from within the program.  However, there are several other GS/OS programs,
utilities, NDA's, CDA,s and such, that will allow you to do a screen capture of
the entire screen as an SHR graphic file or with options for certain specific
NDA types and with some of these other GS/OS screen capture programs, you can
use the mouse and cursor to outline just the portion of the screen that displays
the actual JPEG graphic displayed within the JPEG View GS program window. 

As such you can capture the JPEG grayscale displayed portion of the graphic on
screen as a grayscale SHR standard graphic. Color would be nice. But, even with
being limited to just grayscale display, an SHR graphic format can offer a nice,
clear, clean and well detailed graphic to view or use for your own individual
needs.

This program can only see a graphic file that ends with .jpg, .jpeg or .jfif as a
graphic file and can only load it if the file has any of these endings with its
file name. The JPEG View GS program is not concerned with the file type and can
load any file type, as long as it's actually a jpg, jpeg or jfif graphic file of
those proper structure and content. 

When you select a jpg, jpeg or jfif graphic file to load, the program will load
it, decompress it with the file activity and conversion stats to the right,
displayed in text on the graphic screen display window and then will display a
thumbnail preview size of the graphic in the top left of the same graphic screen
display window.  When the program has finished with all this, then it will do
an automatic full sized display of the graphic to the same window, which
(depending on the original graphic file size) may often need to be scrolled up
and down or left to right to view the entire graphic file contents. 

If no such larger display occurs and only the thumbnail size graphic is only
displayed, then that's the actual size of the graphic. If the graphic file is
large and complex in content, it will take longer to render the thumbnail
preview and display the full screen window of the graphic.

The program is very stable when functioning and I've yet to have the program
lock up or cause a system crash, using it with either a IIgs ROM 01 or ROM 03
with GS/OS v6.0.1 or with the two Apple IIgs emulators Bernie and Gus on any
Macintosh PPC machine model I've used it with.


That's All Folks !
