| !!!!!!!! THIS NEXT BIT IS IMPORTANT !!!!!!!!! |
| ************************************************************************* |
| |
| If you have defined MNG_FULL_CMS (and are using lcms), you will have to |
| think hard about the following routines. |
| |
| lcms requires 2 profiles to work off the differences in the input-image |
| and the output-device. The ICC profile for the input-image will be |
| embedded within it to reflect its color-characteristics, but the output |
| profile depends on the output-device, which is something only *YOU* know |
| about. sRGB (standard RGB) is common for x86 compatible environments |
| (eg. Windows, Linux and some others) |
| |
| If you are compiling for a sRGB compliant system you probably won't have |
| to do anything special. (unless you want to of course) |
| |
| If you are compiling for a non-sRGB compliant system |
| (eg. SGI, Mac, Next, others...) |
| you *MUST* define a proper ICC profile for the generic output-device |
| associated with that platform. |
| |
| In either event, you may also want to offer an option to your users to |
| set the profile manually, or, if you know how, set it from a |
| system-defined default. |
| |
| TO RECAP: for sRGB systems (Windows, Linux) no action required! |
| for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED! |
| |
| Please visit http://www.srgb.com, http://www.color.org and |
| http://www.littlecms.com for more info. |
