ANSI/<strong>NIST</strong>-ITL 1-<strong>2011</strong> - UPDATE 2013 DRAFT VERSION8.14.6 Field 14.006: Horizontal line length / HLLThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.1 <strong>for</strong> details.8.14.7 Field 14.007: Vertical line length / VLLThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.2 <strong>for</strong> details.8.14.8 Field 14.008: Scale units / SLCThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.3 <strong>for</strong> details.8.14.9 Field 14.009: Transmitted horizontal pixel scale / THPSThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.4 <strong>for</strong> details.8.14.10 Field 14.010: Transmitted vertical pixel scale / TVPSThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.5 <strong>for</strong> details.8.14.11 Field 14.011: Compression algorithm / CGAThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. It shall specify the algorithm used to compress thetransmitted grayscale images. See Table 15 <strong>for</strong> a list of the codes, and Section 7.7.9.1 <strong>for</strong>a detailed description of this field.8.14.12 Field 14.012: Bits per pixel / BPXThis field is mandatory if an image is present in Field 14.999: Fingerprint image /DATA. Otherwise it is absent. See Section 7.7.8.6 <strong>for</strong> details.8.14.13 Field 14.013: Friction ridge generalized position / FGPThis field is mandatory. See Section 7.7.4.2 <strong>for</strong> details. In the 2007 and 2008 versions ofthe standard, this field had a repeating subfield that could occur up to 6 times. Since onlyone image is sent per record, the maximum should have been 1. To maintain backwardcompatibility, the subfield structure has been retained, but with a maximum occurrenceof one.8.14.14 Field 14.014: Print position descriptors / PPDThis field shall be present if and only if the finger position code “19” appears in Field14.013: Friction ridge generalized position / FGP. See Section 7.7.4.3 <strong>for</strong> details.May, 2013 DRAFT VERSION UPDATE 2013 Page 319
