43/* * Although this library supports all features from the PNG specification * */
44/* * (as MNG descends from it) it does not require the libpng package. * */

47/* * inclusion of support for JNG and Full-Color-Management respectively. * */
48/* * * */
49/* * This library's function is primarily to read and display MNG * */
50/* * animations. It is not meant as a full-featured image-editing * */
51/* * component! It does however offer creation and editing functionality * */
52/* * at the chunk level. * */
53/* * (future modifications may include some more support for creation * */

759 If you have defined MNG_FULL_CMS (and are using lcms), you will have to
760 think hard about the following routines.
761
762 lcms requires 2 profiles to work off the differences in the input-image
763 and the output-device. The ICC profile for the input-image will be
764 embedded within it to reflect its color-characteristics, but the output
765 profile depends on the output-device, which is something only *YOU* know
766 about. sRGB (standard RGB) is common for x86 compatible environments
767 (eg. Windows, Linux and some others)
768
769 If you are compiling for a sRGB compliant system you probably won't have
770 to do anything special. (unless you want to ofcourse)
771
772 If you are compiling for a non-sRGB compliant system
773 (eg. SGI, Mac, Next, others...)
774 you *MUST* define a proper ICC profile for the generic output-device
775 associated with that platform.
776
777 In either event, you may also want to offer an option to your users to
778 set the profile manually, or, if you know how, set it from a
779 system-defined default.
780
781 TO RECAP: for sRGB systems (Windows, Linux) no action required!
782 for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
