/* Modifications by Pablo d'Angelo
* updated to vigra 1.4 by Douglas Wilkins
* as of 18 February 2006:
* - Added UINT16 and UINT32 pixel types.
* - Added support for obtaining extra bands beyond RGB.
* - Added support for a position field that indicates the start of this
* image relative to some global origin.
* - Added support for x and y resolution fields.
* - Added support for ICC Profiles
