Many professionals are familiar with the
problem; quality loss caused by digital image magnification.
In many cases a great deal of time is spent on achieving
only a fairly acceptable enlargement result, however there
are familiar side effects including out-of-focus images and
serrated edges which is illustrative for the lack of
professional magnification software.
PhotoZoom Pro™ 2 is based on S-Spline XL:
a renewed and improved version of our patented,
self-adjusting, many times awarded S-Spline interpolation
technology. As we did with S-Spline, our S-Spline XL
technology again introduces a revolutionary breakthrough in
digital image enlargement. It is able to render sharp and
crisp clear image magnifications, perfectly focused, yet
without the jagged edges, loss of detail or lack of
photorealism that normally come with enlarging images.

About ICC-color
management
The International Color Consortium ICC was founded in 1992. A standard for color
profiles was published in 1993 by the ICC. Today the ICC-standard for color
profiles is established in most color management systems.
ICC-profiles are used in color management systems to get an accurate color
reproduction on different output devices. ICC-profiles are OS independent and
can be used on Windows based computers, on Macs and on Unix machines. ColorSync
is doing the color management in the Mac OS. On Windows based PCs ICM 2.0 is
available in Windows 98/2000/XP. Today most popular DTP and image editing
applications have an implemented support for color management with ICC-profiles.
The following illustration shows how ICC-color management controls the color
reproduction from input to output device:
An ICC-color management system consists of color profiles and color engine
(CMM). The color engine is doing the color transformation.
Inside of a color profile you find a matrix or table (LookUpTable, LUT) which
are used for for calculation from device color space to the device independent
color space (PCS). The device color space is RGB for scanner and display and
CMYK for printer. ICC-profiles have the extension *.icc or *.icm.
The color engine (CMM) is doing the calculation during a color transformation
from device color space to the profile connection space (PCS) or vice versa by
using the ICC-profiles. All calculations or automatically done by the color
engine.
The device independent color space is called profile-connection-space (PCS). The
ICC-standard allows two profile-connection-spaces: CIE-XYZ and CIELab. Both
color spaces can be converted lossless. For matrix-based-profiles a
transformation to CIE-XYZ is used. ICC-profiles which include a look-up-table (LUT)
for the color transformation convert to CIELab.
--------------------------------------------------------------------------------
About ICC-profiles
In ICC-profiles there exist two kinds of calculation methods:
- Matrix-based-profiles with 3x3-matrix and Tone Reproduction Curve (TRC)
- LUT-based-profiles with multidimensional Look-Up-Table (CLUT), Input- and
Output-Curves
Matrix-based-profiles are only used for RGB-devices as display, scanner and
workspace. They are quite small (20-100 kByte) in comparison to LUT-based-profiles,
because only some values have to be stored in the profile.
LUT-based-profiles are used for all output devices which work in CMYK-system.
Some RGB-devices like scanners, digital cameras or digital RGB-printer also use
LUT-based-profiles. Because of the multidimensional look-up-tables inside of the
profiles the size of LUT-based profiles is between 400 kByte and 2 MByte.
