Identifies DICOM Photometric Interpretations. See DICOM specification PS 3.3 C.7.6.3.1.2 for more details.

Values:

MED_DCM_PHOTO_INT_ARGB	This value has been deprecated and will be removed from the public API in a future release.
MED_DCM_PHOTO_INT_CMYK	This value has been deprecated and will be removed from the public API in a future release.
MED_DCM_PHOTO_INT_HSV	This value has been deprecated and will be removed from the public API in a future release.
MED_DCM_PHOTO_INT_MONOCHROME1	Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as white.
MED_DCM_PHOTO_INT_MONOCHROME2	Pixel data represent a single monochrome image plane. The minimum sample value is intended to be displayed as black.
MED_DCM_PHOTO_INT_PALETTE_COLOR	Pixel data describe a color image with a single sample per pixel (single image plane). The pixel value is used as an index into each of the Red, Blue, and Green Palette Color Lookup Tables
MED_DCM_PHOTO_INT_RGB	Pixel data represent a color image described by red, green, and blue image planes.
MED_DCM_PHOTO_INT_UNKNOWN	Photometric interpretation is unknown.
MED_DCM_PHOTO_INT_YBR_FULL	Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr).
MED_DCM_PHOTO_INT_YBR_FULL_422	The same as YBR_FULL except that the Cb and Cr values are sampled horizontally at half the Y rate and as a result there are half as many Cb and Cr values as Y values.
MED_DCM_PHOTO_INT_YBR_ICT	Irreversible Color Transformation. Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr). Used with JPEG 2000 transfer syntax.
MED_DCM_PHOTO_INT_YBR_PARTIAL_422	The same as YBR_FULL_422 with certain limitations. See DICOM specification PS 3.3 for more detail.
MED_DCM_PHOTO_INT_YBR_RCT	Reversible Color Transformation. Pixel data represent a color image described by one luminance (Y) and two chrominance planes (Cb and Cr). Used with JPEG 2000 transfer syntax.
