Imagelab and its accompanying suite of utilities is one of the
treasures I found on the German CD-ROM PD/Shareware disk Ausgabe 1.
It was confusing to me at first - especially since I don't read
German. After translating the .RSC file into English courtesy of my
German to English dictionary and a whole lot of "by guess and by gosh"
I discovered that the program is very powerful indeed despite a few
quirks. The executables included have been translated into English as
best I am able as have the .RSC files. The documents are beyond my
capabilities.
What you will find here is Imagelab itself for photo processing,
GIF-TIFF for converting GIFs into B&W format or converting B&W files
into GIF or TIF format. GIF-TIFF will convert TIF files of one
particular and, apparently, rarely used format into B&W file format.
Imagetool is a front end for some of the Utilities in the Utility
folder. It provides the ability to rasterize a B&W file into a 4X4 or
8x8 matrix halftone IMG. The IMG2B&W utility converts IMG's from hand
scanners into B&W grayscale files. The maximum dimension either
horizontally or vertically must not exceed 1200 pixels. This may
prove useful to those who have purchased a handscanner and software
that does not provide for saving in anything but IMG format. The
resulting B&W grayscale files will be reduced in size considerably
depending on which matrix size you choose. a 4X4 matrix will give 16
grays, 6X6 36 grays, etc.
I find using GEMView as a front end file converter to change TIF's,
JPG's, TGA's, PCD's, etc into GIF format works quite well. The GIF's
are then converted to B&W (or B_W since you can't use "&" in a
filename from the keyboard) with GIF-TIFF for processing in Imagelab.
When they are finished the B&W is converted back to GIF format with
GIF-TIFF and imported into PicSwitch 1.1 for dithering and conversion
to IMG format. The finished product can be used in Calamus,
Pagestream, Timeworks Publisher, First Word+, AtariWorks, Write On,
That's Write, Calligrapher - in other words, anything that will
import IMG graphic files. The output will exploit your printer's
potential to its fullest.
Imagelab runs in ST High resolution on all ST's, STe's, Falcon or TT.
If you have a medium resolution monitor use SEBRA.PRG included in the
AUTO folder to emulate the high resolution screen. It works better
than any of the other high resolution emulators I have tried.
Operation of Imagelab is too complex for a short readme file but here
are a few tips to get you going.
1 Load one of the FACExx.ORG files, resize it 200% then
select Equal Distribution under the Process menu
- surprise, surprise!
2 Load MAEDCHEN.B_W, select Gray Ops under the Process
menu, load SOLAR_01.LUT then click on Apply. Interesting
effect, don't you think?
3 Load MAEDCHEN.B_W again, hit [Control]-C to copy it into
a new window, select User Defined Filter under the Process
menu, load LAPLACE1.FIL then click on Apply. After the mouse
finishes wiggling his ears (no kidding) the image will be
repainted (doesn't look very useful, does it?). Click on
Image to Buffer under the Edit menu then click in the
original picture's window to select it. Click on Merge also
under the Edit menu. Enter 10% as the buffer value and 90%
as the image value and press return. Finally click in the
original window again. Voila! Maedchen is enhanced by a
10% sharpening and adjustment of grayscale values.
The Gray Ops lookup tables include all the original tables plus a few
of my own creation. I have also created a few additional Filters for
your enjoyment. As I said, use of Imagelab is too complex for a short
readme file. The program is easy enough to use that you should find
yourself up to speed fairly quickly. I plan to include a detailed
tutorial on Imagelab in an upcoming book along with several other PD
and shareware photo processing/programs. The tutorial will include
sections describing the functions of various transforms and how to
create custom filters.
A few final words - MAEDCHEN.B_W is copyright protected any is not to
be used for any commercial application nor distributed except as part
of the Imagelab suite. FACE01 and FACE02.ORG are the property of NASA
and may be used in publication or redistributed as long as they are
