ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONThe formats all store sampled pixel data from rectilinear images. The data shall be encodedas a raw array of intensity values, a raw array of red green blue color values, or as losslesslycompressed or lossy-compressed versions thereof. Two of the formats are specialized forsmall record sizes; these are achieved by cropping and masking the images to supportefficient compression (see Field 17.032: Iris storage format / ISF).Table 88 Type-17 record layoutFieldNumberMnemonic Content Description Condcode17.001 RECORD HEADER MCharacterTypeMIn#Max#ValueConstraintsencoding specific:encoding specific: seesee Annex B:Annex B: TraditionalTraditional encodingencoding or Annex C:or Annex C: NIEMconformantNIEM-conformantencoding rulesencoding rulesOccurrenceMIn#Max#1 117.002 IDCINFORMATIONDESIGNATION CHARACTERM N 1 20 < IDC < 99integer1 117.003 ELR EYE LABEL M N 1 1 ELR = 0, 1 or 2 1 117.004 SRC SOURCE AGENCY M U 1 * None 1 117.005 ICD IRIS CAPTURE DATE MSee Section 7.7.2.3Local dateencoding specific:see Annex B:Traditional encodingor Annex C: NIEMconformantencodingrulesSee Section 7.7.2.3Local dateencoding specific: seeAnnex B:Traditional encodingor Annex C: NIEMconformantencoding rules1 117.006 HLL HORIZONTAL LINE LENGTH D N 2 517.007 VLL VERTICAL LINE LENGTH D N 2 510 < HLL < 99999positive integer10 < VLL < 99999positive integer0 10 117.008 SLC SCALE UNITS D N 1 117.009 THPS17.010 TVPSTRANSMITTEDHORIZONTAL PIXEL SCALETRANSMITTED VERTICALPIXEL SCALE17.011 CGA COMPRESSION ALGORITHM D AN 3 40 < SLC < 2integer0 1D N 1 5 positive integer 0 1D N 1 5 positive integer 0 1CGA =NONE, PNG, JP2 orJP2L0 117.012 BPX BITS PER PIXEL D N 1 2 8 < BPX < 99 166 0 1May, 2013 DRAFT VERSION UPDATE 2013 Page 345
