DPYAN2K 1C 02 April 2001 NIST NFIS Reference Manual dpyan2k display image and minutiae contents of an ANSI/NIST file. dpyan2k options <ANSI_NIST > -a n -v -x -b n -i -n -p n -W n -H n -X n -Y n -T title -d display Dpyan2k displays in a sequence of X11 windows all the image records and overlays any corresponding minutiae from Type-9 records contained in an ANSI/NIST-ITL 1-2000 file. If multiple input files are specified, dpyan2k reads each ANSI/NIST file into memory and displays its contents, one file at a time. Multiple image records within an ANSI/NIST file are displayed simultaneously by forking background window processes, one for each image record. If an image is too large to be displayed on the screen, the upper left hand corner will be displayed and the rest of the image can be moved into view by holding down a mouse button, moving in the direction desired, and then releasing the button. Button presses when another button(s) is already down and button releases when another button(s) is still down are ignored. Users may remove a displayed image window by striking any key within that window. Once all windows associated with a particular ANSI/NIST file have been removed, the utility proceeds to display the contents of the next ANSI/NIST file listed on the command line. -a n sets drag accelerator to n — changes in pointer position will result in n shifts in the displayed image [1]. -v turns on verbose output. -x turns on debug mode, causing a core dump when an X11 error occurs. -b n sets border width to n pixels [4]. -i directs the utility to use the FBI/IAFIS fields 13-23 in a Type-9 record when overlaying minutiae on an image. -n directs the utility to use the NIST fields 5-12 in a Type-9 record when overlaying minutiae on an image. This is the default setting. -p sets the pixel width of overlayed minutia points [3]. -W n displays image in a window of width n pixels. -H n displays image in a window of height n pixels. -X n positions image window with top-left corner n pixels to the right of the display's top-left corner [0]. -Y n positions image window with top-left corner n pixels below the display's top-left corner [0]. -T title sets all image window names to title. -d display connects to an alternate X11 display. <ANSI_NIST ...> one or more ANSI/NIST files with images and possbily minutiae to be displayed.
