 Additional
utilities
Python
bindings for windows
These are the
needed files for python 2.2 under windows. You need the _lcms.pyd file
holding the binary plus the lcms.py shadow wrapper. Refer to python
documentation for instructions on where place those files.
TIFF
profile applier
This command
line program does apply icc profiles onto TIFF files. Very adequate
for bulk batch mode. It uses Sam Leffler's LIBTIFF for file I/O, so
it is also an example on how to use lcms with this library. See http://www.remotesensing.org/libtiff/
for more info about libtiff.
It
can do following things (of course
if you have right icc profiles)
Convert
RGB tiff from any monitor space to any other monitor space.
Convert
from scanner space to sRGB (or monitor) space.
Make
accurate separations (i.e., RGB -> CMYK) depending of target
printer.
Recover
RGB from separation (i.e. CMYK->RGB)
Convert
separations between printers.
Convert
CIEL*a*b TIFF to sRGB
And
cannot:
Do
anything with bilevel images (this is color management stuff remember?)
Similar
to anterior, but dealing with JPEG. It uses Tom Lane's IJG library
http://www.ijg.org If you plan to use CMYK JPEG, you need also this
patched files jccolor.c and jdcolor.c
It
can do following things (of
course if you have right icc profiles)
Convert
RGB JPEG from any monitor space to any other monitor space.
Convert
from scanner space to sRGB (or monitor) space.
Make
accurate separations (i.e., RGB -> CMYK) depending of
target printer.
Recover
RGB from separation (i.e. CMYK->RGB)
Convert
separations between printers.
Convert
CIEL*a*b ITU/Fax JPEG to sRGB
Profile to PostScript
This
utility can translate a ICC profile to a PostScript Color Space
Array (CSA) or Color Rendering Dictionary (CRD).
Color
space conversion calculator
This
command line program does compute colorspace conversion based on icc
profiles. Additionally, it can show XYZ and Lab values of PCS, and up
to 16 bits of precision (48, 64 bits per pixel). If you ever have been
searching for a universal colorspace conversion utility, check this
one!
It
can handle following colorspaces (of
course if you have right icc profiles):
RGB,
CMY, CMYK, Lab, XYZ, LUV, YCbCr, xyY, Grayscale, HSV, HLS.
Hexachrome, 5 inks
Full
source code can be found in littlecms distribution.
Device link generator
Links
two or more profiles into a single devicelink profile.
White
point inferer
This
command line program does show the white point of any profile, drawing
the isoline for black body (temperature) correlation. It can also show
the nearest black body locus of a XYZ value.
Profiles
pack
Several
assorted icc profiles for trick & trapping
JPEG ITU Fax L*a*b
profile Implements ITU/Fax Colorspace for both read and write
TIFFLab8 profile
using D50 instead of D65 (Adobe)
Assorted profiles
pack. Contains generic & special purpose profiles.
lcms demo program (old)
The demo program can help you to evaluate the functionality of lcms.
It includes profiles and an installation program. This program handles
embedded profiles in TIFF, JPEG and PNG, as well as CMY, CMYK, CIELAB,
YCbCr, Luv... Minimum requirement are Pentium 90/16Mb and Win95. (About
2Mb)
Download
the demo (.exe) for Win32
NOTE: This demo
is still using ver 1.06, so the current library is much more powerful!.
