With ICS you can make your scans look like from the professionals.
By  using  ICS  scan  quality  is  DRAMATICLY(!)  improved without
requiring the user to manualy adjust scan colors while scanning.

This is the first release of ICS after nearly two years development.
Support for ICC Profiles and more type of devices (printers,...)
is planned for the next major release.

ICS already is directly supported by ScanQuix V4, ScanTrax V2.2.
Other scanner drivers authors will soon add direct ICS support to
their scanner drivers.  But ICS can also work independent of any
specific scanner software using a stand-alone image file converter.

ICS does work in 3 steps:

 - You do scan a calibration target with your scanner software
   and use the incl. ScanTarget programm to create a profile
   for your scanner.

 - You do select your monitor or standard (PAL, sRGB, NTSC,...)
   you want to color correct the scan for.

 - Now all scans with your scanner software will be color corrected
   automaticly.

It's as easy as that...

ICS supports standard IT 8.7 (ISO 12641) from Kodak, Agfa, Fuji,
CorelDraw/PhotoPaint and "Epson Color Reference Chart V1.0"
calibration targets.





Changes since V1.00:

-  Added: Generation of the Scanner RGB->CIE Lab approximation now offers higher precission.
          The mean CIE Lab dE color fault is now below usualy below dE 1(!) and
          thus out of visible range. Maximum fault and standard deviation also
          got greatly reduced. ICS should now get close to other high end Mac/PC solutions
          as far as scanner characterization goes. (13 hours)
-  Added: The new Scanner RGB->CIE Lab function also offers more speed beside
          increased quality. There is even a speedup in the final generation
          of the RGB LUT during initialization of ICS. (6 hours)
-  Minor bug: SAVE flag might got set in ScanTarget filerequester. Fixed (1 hour)
-  BUG:  Kodak Dmin/Dmax values in references files were not read correctly
         by ScanTarget causing color faults in the final correction. Fixed.
         Thanks goes to KWLee (Primax) for finding this bug in the scanner profile. (8 hours)
-  Added: ICS now checks for scanner profile to be version >=2 (just to make
          sure everybody only uses profiles generated by the fixed ScanTarget V1.01). (2 hours)
-  Minor bug: NUMBER_OF_FIELDS was set to 9 instead of 4 in example IT 8,7 reference file. (1 min)
-  BUG:  A bug in the used AsyncIO library causes the GIF reading routines to crash.
         Switched to normal file IO until asyncio library got fixed by author.
         The bug mainly showed up with interlaced GIF images causing
         multiple SeekAsync calls (wich cause the crash in ASyncIO). (10 hours)
-  Added: GIF module now does much less Seek() calls causing a speedup. (3 hours)
-  Added: manual updated. (2 hours)
-  Minor bug: Selecting a wrong file as reference file in ScanTarget could
          cause a large amount of requesters being displayed. Now
          a single warning with a final abort requester will appear. (1 hour).
