Write colour image to file (in dipIO)
dip_Error dipio_ImageWriteColour ( image, filename, photometric, format, compression )
This function writes a colour image to a file, overwriting any other file with the same name. photometric must be set to the correct value. Not all file formats support all photometric values, and some don't support colour at all. Get the format ID through the registry functions. See File formats recognized by dipIO for a list of currently supported formats. If format is 0, ICSv2 is used.

DIPIO_PHM_CMYK | CMYK image (the first four planes are cyan, magenta, yellow and black) |
DIPIO_PHM_CIELUV | CIE L*u'v' image (the first three planes are luminosity, u* and v*) |
DIPIO_PHM_CIELAB | CIE L*a*b* image (the first three planes are luminosity, a* and b*) |
DIPIO_PHM_CIEXYZ | CIE XYZ (the first three planes are X, Y and Z) |
DIPIO_PHM_CIEYXY | CIE Yxy (the first three planes are Y, x and y) |
DIPIO_PHM_HCV | HCV image (the first three planes are hue, chroma and value) |
DIPIO_PHM_HSV | HSV image (the first three planes are hue, saturation and value) |
DIPIO_PHM_DEFAULT | Same as DIPIO_PHM_GREYVALUE |
