IMGCON v1.4 (c) Copr. 1990 Anthony Rizzolo
───────────────────────────────────────────────────────────
IMGCON V1.4 DIRECTIONS AND USE
Should you find this program useful, you should register it. You may freely
distribute copies of this program in its UNMODIFIED state with the inclusion
of the authors copyright notice. You may NOT charge for distrubtion of this
program.
WHAT IS IMGCON ?
IMGCON is a program for converting images between different image
formats. It also allows you to display the images on your screen.
IMGCON has a windowed interface to make it user friendly.
SYSTEM REQUIREMENTS
IMGCON requires only enough memory to load itself (about 150K) of
available memory. GIF will require about another 16K at execution
time.
1.0 HOW TO USE IMGCON
1.1 Command syntax: imgcon d:\windows
The one command line argument is the picture directory to look for the
source image files. The output file is placed into the current directory
unless this is superseded by the OUT NAME command.
IMGCON has a window style interface. It uses a vertical menu bar
and pick lists to select files.
There are also quite a few fixes in the SIXEL image processing. It
will now handle images larger than 800x252 if they start with the
"1;1;x;y" after the <ESC>q.
It will also handle these larger images if they don't have the qualifier
after the <ESC>q. This however takes an extra pass through the file in
order to figure out the image dimensions.
In addition there is now a new feature in the display section. The
display functionality will now select the best available mode for the
image to be displayed. You can of course override this feature by
selecting a particular output resolution. If the image does not fit
into the selected resolution, it will be scaled to fit the physical
screen dimensions.
PCX files are now fully compressed in this version. This means that
your image will not take up excessive disk space any more.
| V1.4 Fixe two problems which were reported. One had to do with an
| extra byte on the image file size when converting to PCX format. This
| was caused by a math error when we were recomputing the information to
| put into the header.
|
| V1.4 also fixed a problem in GIF file processing which was returning
| an error during the conversion of some GIF files that the scan line
| had been overrun or we got an unexpected EOF.
1.2 IMGCON.INI file
In addition IMGCON will read an initlialization file to get some
paramaters which are useful. The file has the following arguments:
1) 320x200x256=hh - Replaces the mode information for 320x200x256
in the Video mode table with the hex value 'hh'.
The default is mode 13.
2) 640x350x256=hh - Replaces the mode information for 640x350x256
in the Video mode table with the hex value 'hh'.
The default is mode 2dh.
3) 640x400x256=hh - Replaces the mode information for 640x400x256
in the Video mode table with the hex value 'hh'.
The default is mode 2eh.
4) 640x480x256=hh - Replaces the mode information for 640x480x256
in the Video mode table with the hex value 'hh'.
The default is mode 2eh.
5) 800x600x256=hh - Replaces the mode information for 800x600x256
in the Video mode table with the hex value 'hh'.
The default is mode 30.
6) 1024x768x256=hh - Sets up mode 1024x768x256 (completely untested
as I do not have a board which supports this mode.
6) USE_BIOS=TRUE/FALSE - Decides if memory moves will be used to put
the image on the screen in display mode. I have
only tested this on the ORCHID DESIGNER VGA-512
board, so if things seem weird, then use the BIOS
routines instead. It will be slower. I can get
hardware specs for some of the other boards, but
if you find your board does not work, if you can
provide me with enough information I will try to
add it to the supported board list.
1.3 Using the IMGCON menues
MAIN MENU: CONVERT INPUT_PATH OUTPUT_FILES VIDEO_MODE DISPLAY EXIT
The IMGCON menus are fairly straight forward to use. When you start
up you will be at the horizontal menu bar. You can use the arrow
keys to select a menu item, or type the first letter of the MENU ITEM.
The EXIT menu is not a pull down, and requires a <CR> key to confirm
it when you type the character. If you are using the ARROW keys to
select you will need to confirm you selection when you get to it by
typing a <CR>.
Basically the menus will take you through the required information
to complete the menu. The INPUT PATH and OUTPUT FILES menu selections
require you to enter text into the fields. If you specify a particular
file name, it uses that file name for output (ie: You should not
multi-select under convert). You don't have to type the extension as
IMGCON always makes sure that is correct for the image type to be
output. If you type a *(wildcard) for the file name, it will replace
the * with the input file name on the conversions.
You may multi-select files from the pull down menu, when you have
completed your selection, you should type an <ESC> key. This will
signal that you are done selecting and the given function (CONVERT or
DISPLAY) is performed for each of the files.
If you are in the middle of a long display list and you wish to abort
a single image, then simply type any character and the image will abort
and proceed onto the next one. If you want to abort this image and
all the images that follow it, you should type the <ESC> key. The
same applys to the conversion menu. If a conversion is aborted in
the middle, the output file will be deleted.

Thank you.
3.0 FUTURE DEVELOPMENT PLANS
2) Output to GIF FORMAT.
3) Output to VT240 SIXEL format.
4) Output to Postscript or Encapsulated postscript.
5) Output of X-WINDOW bit map files.
6) Pallete merge functionality (includes merged pallete generation and
inclusion into the image).
7) Allowing use of a microsoft mouse to select menu items.
8) Image scrolling for images that do not fit into the physical
bounds of the screen. (Currently they are scaled to fit within the
bounds of the screen).
9) Input/Output to "other" formats.
10) Automatic Image detection for input images.
11) Compression on BMP files.
Also if you have any suggestions for features or modifications you
would like to see in the program please feel free to let me know. I
am just starting out so I do appreciate any help or feedback you can
give me.
