IceTEnum icetImageGetColorFormat( const IceTImage image );
IceTEnum icetImageGetDepthFormat( const IceTImage image );
Description
icetImageGetColorFormatand icetImageGetDepthFormatreturn an entry in an enumeration that specifies the data format stored in the given
image. This format determines which one of the icetImageGetColor or icetImageGetDepth functions to use and the form of the resulting data.

Each entry is in the range from 0.0 (near plane) to 1.0 (far plane) and is stored as a 32-bit float.
ICET_IMAGE_DEPTH_NONE
No depth values are stored in the image.
