PICEM is a general purpose picture view program which also allows you to
adjust the brightness and contrast in your pictures and save them back out.
PICEM is not shareware, it is freeware, meaning that you can copy and
distribute PICEM on a non-profit basis (you cannot sell it).
.PIC images are PC Paint and PICTOR images. PC Paint is published by MSC
tech, (previously named "Mouse Systems"). PICTOR is the Paint program
which is part of the GRASP package published by Paul Mace Software.
.PCX images are PC Paintbrush format images. PC Paintbrush is published
by Z-Soft.
.GIF images are Graphics Interchange Format, a generalized picture format
supported by Compuserve, The PICS Trilogy of Forums on Compuserve
is one of the best places to obtain an assortment of image files
including some stunning hiresolution 256 color images (ideal
for VGA and SuperVGA cards).
Keys available in PICEM when in the picture select list screen:
-------------------------------------------------------------------------------
Arrow keys - scroll around picture list to select picture filenames
SPACE - mark/unmark image names for display
* - mark all image names for display
RETURN - display the current selected picture and any others selected
with SPACE
ESC - exit program
Keys available in PICEM while viewing images:
-------------------------------------------------------------------------------
Arrow keys - scroll around picture (if image is larger than screen)
* - reset to original contrast and brightness
+ - increase contrast, (bring out colors in a flat image)
- - decrease contrast, (reduce washed-out dark colors in pale image)
Ins - increase brightness, (bring up details hidden in darkness)
Del - decrease brightness, (reduce the overexposed effect of a high
contrast setting)
1,2...8,9,0 - set speed for +,-,Ins and Del, (how fast contrast and brightness
controls function with 1 slowest and 0 fastest
SPACE - skip to the next picture selected
RETURN - exactly the same as SPACE
TAB - Scale image to exactly screen size (great for large images
that don't fit on screen, favorite of users of standard
VGAs that use mode W for viewing 640x480 images)
W - write picture to disk as BAS PIC GIF PCX or IMG
BACKSPACE - display test pattern (in 256 color modes only)
ESC - exit program
Command line Parameters for PICEM
-------------------------------------------------------------------------------
PICEM {/k /l /w:t /v:vmode{,xsize,ysize,vnum} /d:x,y /m /c} fname ...
/k - do not wait for a keypress between pictures
/l - display pictures in continous loop
/s - scale all images to screen size (like TAB key)
/w:t - Wait t number of 1/100ths of a second after each picture
/n - Don't sort list of filenames
/e - Don't clear screen on exit (leave image on screen)
/d:x,y - set lower left hand coordinates to display picture
/d - force centering of image (default)
/m - multi-picture display prevents palette switch between
display of multiple images
/c - clear the screen
/v:vnum
vnum - BIOS video mode number to set (vmode defaults to 'L')
this is the short order version of the full /v: option
it is intended for SuperVGA modes.
/v:vmode{,xsize,ysize,vnum}
vmode - video mode most similar to the mode you are choosing:
A = CGA 4 color N = Hercules InColor 720x348 16 color
B = PCjr/Tandy 16 color O = VGA/MCGA 640x480 2 color
C = CGA 640x200 2 color P = EGA/VGA 800x600 2 color
D = EGA 640x200 16 color Q = EGA/VGA 800x600 16 color
E = EGA 640x350 2 color R = S-VGA 640x400 256 color
F = EGA 640x350 4 color S = S-VGA 640x480 256 color
G = EGA 640x350 16 color T = S-VGA 800x600 256 color
H = Hercules 720x348 2 color U = S-VGA 1024x768 2 color
I = VGA 640x350 16 color V = S-VGA 1024x768 16 color
J = EGA 320x200 16 color W = VGA 360x480 256 color
K = AT&T/Toshiba 640x400 2 color X = S-VGA 1024x768 256 color
L = VGA/MCGA 320x200 256 color Y = S-VGA 1280x1024 16 color
M = VGA 640x480 16 color Z = S-VGA 1280x1024 256 color
xsize - optional width of the video mode you have chosen in pixels
ysize - optional height of the video mode you have chosen in pixels
vnum - the BIOS video mode number for the mode you have chosen
PICEM supports a wide variety of Video boards, with a primary emphasis on
VGA/SuperVGA boards. On VGA boards PICEM defaults to /V:W which is
360x480 256 colors (a non-standard mode, but it's the best 256 color mode
available on a standard VGA). On SuperVGA boards PICEM defaults to /V:R
which is 640x350/640x400 256 colors on boards with only 256k, and /V:S
which is 640x480 256 colors on boards that have 512k or more.
Some boards such as the ATI and Orchid may be capable of 800x600 256
colors, but since many monitors will not handle this mode, I don't
default to it, you can manually select it with /V:T.
Also if your board has a odd resolution 256 color mode that you would like
to take advantage of (such as the Everex 512x480 mode, or the Genoa 720x512
mode) you can manually override the BIOS mode used. For instance to set
512x480 on a Everex board we would do PICEM /V:0x15 (the 0x means hexidecimal,
the way most bios mode numbers are written in manuals, the same number in
decimal would be PICEM /V:21).
For any bug reports I can be contacted on CIS (Compuserve) ID:75300,2137 in
the PICS Forum, To enter the PICS forum on Compuserve just type "GO PICS"
from any prompt.

Bug fixes:
10/09/91 - /d:0,0 will now work (it used to center the image)
10/11/91 - /d with no colon resets to centering images
and the /d: and /d parm can be mixed with filenames
to display images at different positions.
10/12/91 - oops, the multiple /d: and /d parms were skipping
filenames.
10/14/91 - /c is new command line option to force screen to clear.
/m is new command line option to prevent palette change
between images.
the first /d: and /d parms MUST be just before the
first filename after all other parms. This applies
to all parms that can be mixed in with filenames
(right now this is /d: /d /c and /m).
@filename on the command line allows a list of command
line parms to be read it from a file.
New tiny version of picem called TPICEM.EXE is now
available. It removed the image selection screen, the
palette manipulation (brightness/contrast), the test
screen, the help screens and the image save.
10/19/91 - support for OAK Tech OTI-077 chipset is in
10/24/91 - better accuracy and overflow checking in brightness and
contrast control code, it's completely rewritten, much
smoother.
10/25/91 - * key selects all pictures when in picture list display.
1/20/92 - new version number because support for ACUMOS and ATI are
added, and some other library bugs are fixed.
1/24/92 - GIF load code corrected to handle extension blocks at the
beginning of images.
10/26/92 - I removed the long list of chipset makers and video mode
numbers. This information is still available in VGAKIT.
6/25/93 - Rewritten to use new virtual memory system I created for
Multi-Media GRASP 5.0
EMS/XMS and disk swapping support
HiColor video modes (15 and 16 bit)
New 32bit bitblit code (on 386/486 processors)
High speed scaling
Uncompressed Targa and TIFF images support
Better support of odd text modes
