ANSI/<strong>NIST</strong>-ITL 1-<strong>2011</strong> - UPDATE 2013 DRAFT VERSION8.15.11 Field 15.011: Compression algorithm / CGAThis field is mandatory if an image is present in Field 15.999. Otherwise it is absent. Itshall specify the algorithm used to compress the transmitted grayscale images. See Table15 <strong>for</strong> a list of the codes, and Section 7.7.9.1.8.15.12 Field 15.012: Bits per pixel / BPXThis field is mandatory if an image is present in Field 15.999. Otherwise it is absent.See Section 7.7.8.6 <strong>for</strong> details.8.15.13 Field 15.013: Friction ridge generalized position / FGPThis mandatory field shall contain the palm print position that matches the palmprintimage. Valid codes range from 20 to 38, or 81 to 84. See Table 8. See Section 7.7.4.2<strong>for</strong> details.8.15.14 Field 15.016: Scanned horizontal pixel scale / SHPSThis is an optional field. See Section 7.7.8.7 <strong>for</strong> details.8.15.15 Field 15.017: Scanned vertical pixel scale / SVPSThis is an optional field. See Section 7.7.8.8 <strong>for</strong> details.8.15.16 Field 15.018: Amputated or bandaged / AMPThis optional field shall specify if a hand is amputated or bandaged. Multiple subfieldsmay be entered and each shall contain two in<strong>for</strong>mation items.• The first item is the friction ridge amputated or bandaged position / FRAPbetween 21 and 38 or 81 through 84 as chosen from Table 8. This in<strong>for</strong>mationitem is called the friction ridge amputated or bandaged position / FRAP todifferentiate it from FGP.• The second item is the amputated or bandaged code / ABC, also known as theAMPCD. Table 85 is a list of allowable indicators <strong>for</strong> the AMPCD.If an entire hand is missing, either 83 (right full palm, including writer's palm) or 84 (leftfull palm, including writer's palm) shall be entered <strong>for</strong> FRAP. A partially scarred palmshould be printed. XX shall be used only when a partial print exists due to amputation;there<strong>for</strong>e it contains some friction ridge detail. UP shall be used with the complete blockwhere an image was to be transmitted, but there is no image due to amputation or totallack of friction ridge detail (such as with a bandage). An image with a scar should not bemarked XX or UP.8.15.17 Field 15.020: Comment / COMThis is an optional field. See Section 7.4.4 <strong>for</strong> details.May, 2013 DRAFT VERSION UPDATE 2013 Page 333
