Arguments:
| Name | Type | Description |
| hIGear | HIGEAR | ImageGear handle of image. |
| dwGrpID | DWORD | Identifier of group to use. |
| lpnTranspMode | LPAT_MODE | Pointer where TranspMode options are returned. If NULL, then this parameter is ignored. |
| lpTranspColor | LPAT_RGB | Pointer where TranspColor option is returned. If NULL, then this parameter is ignored. |
| hphIMask | LPHIGEAR | Pointer where TranspMask option is returned. If NULL, then this parameter is ignored. Please note that this function does not change or delete the value of TranspMask, but only makes its copy. |
| lpMaskRect | LPAT_RECTANGLE | Pointer to where to return the value of the MaskRect option. If NULL, then this parameter is ignored. If an empty rectangle is returned then it is initialized with a rectangle equal to the entire mask image. |
| lpMaskLocation | LPAT_POINT | Pointer to where to return the value of MaskLocation option. If NULL, then this parameter is ignored. |
