HIGEAR hIGear; /* HIGEAR handle of image */ AT_ERRCOUNT nErrcount; /* tally of IG errors on */ /* stack */ ART_MARK_INDEX hMarkIndex; /* index to current mark */ ART_MARK_ATTRIBUTES ma; /* structures for */ /* attributes of current */ /* mark */ nErrcount = ART_mark_query(hIGear, hMarkIndex, &ma); if ((ma.dwType == ART_MARK_IMAGE_EMBEDDED) || (ma.dwType == ART_MARK_IMAGE_REFERENCE)) { /* if mark is an embedded image or image reference*/ nErrcount = ART_mark_rotate(hIGear, hMarkIndex, 45.0); } |

Currently only image marks (embedded and image reference) can be rotated.
An error is set if any of the following conditions are met:
- hIGear does not reference a valid ImageGear handle.
- There are no marks with a matching index block.
