Enumerant Notes

SE_IMG_PROJ_TYP_PLANAR

 Used when applying the <Image> to a planar surface.

SE_IMG_PROJ_TYP_CYLINDRICAL

 Used when warping the <Image> to a cylindrical shape. For this case, the
 textured object does not have <Texture Coordinates> or <Tack Points>;
 <Image Anchors> are provided by either the <Image Mapping Function> or
 the <Image> itself.

SE_IMG_PROJ_TYP_SPHERICAL

 Used when warping the <Image> to a spherical shape. For this case, the
 textured object does not have <Texture Coordinates> or <Tack Points>;
 <Image Anchors> are provided by either the <Image Mapping Function> or
 the <Image> itself.
