it won't do any good to turn the checking flags on; if a checking flag

and optionally 031 and 051, but only checking ancillary chunks and not

943
944
If you have defined MNG_FULL_CMS (and are using lcms), you will have to
945
think hard about the following routines.
946
947
lcms requires 2 profiles to work off the differences in the input-image
948
and the output-device. The ICC profile for the input-image will be
949
embedded within it to reflect its color-characteristics, but the output
950
profile depends on the output-device, which is something only *YOU* know
951
about. sRGB (standard RGB) is common for x86 compatible environments
952
(eg. Windows, Linux and some others)
953
954
If you are compiling for a sRGB compliant system you probably won't have
955
to do anything special. (unless you want to of course)
956
957
If you are compiling for a non-sRGB compliant system
958
(eg. SGI, Mac, Next, others...)
959
you *MUST* define a proper ICC profile for the generic output-device
960
associated with that platform.
961
962
In either event, you may also want to offer an option to your users to
963
set the profile manually, or, if you know how, set it from a
964
system-defined default.
965
966
TO RECAP: for sRGB systems (Windows, Linux) no action required!
967
for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!

947
and optionally 031 and 051, but only checking ancillary chunks and not

961
If you have defined MNG_FULL_CMS (and are using lcms), you will have to
962
think hard about the following routines.
963
964
lcms requires 2 profiles to work off the differences in the input-image
965
and the output-device. The ICC profile for the input-image will be
966
embedded within it to reflect its color-characteristics, but the output
967
profile depends on the output-device, which is something only *YOU* know
968
about. sRGB (standard RGB) is common for x86 compatible environments
969
(eg. Windows, Linux and some others)
970
971
If you are compiling for a sRGB compliant system you probably won't have
972
to do anything special. (unless you want to of course)
973
974
If you are compiling for a non-sRGB compliant system
975
(eg. SGI, Mac, Next, others...)
976
you *MUST* define a proper ICC profile for the generic output-device
977
associated with that platform.
978
979
In either event, you may also want to offer an option to your users to
980
set the profile manually, or, if you know how, set it from a
981
system-defined default.
982
983
TO RECAP: for sRGB systems (Windows, Linux) no action required!
984
for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
