NAME

xhdisp -- display "XS_HIS" history records in a qpoe or image file

USAGE

xhdisp image type

DESCRIPTION

The task xhdisp displays history information from a qpoe or image file. The history information is contained in the header parameters "XS_HIS01", "XS_HIS02", "XS_HIS03", etc.

PARAMETERS

image = "" prompt = image file name

The image or qpoe data file. The task tries to access the image as a qpoe file and, failing that, as an image. Therefore, the file extension is only required if an image and a qpoe file exist with the same root.

type = "history" prompt = special history type, if desired

The type of history record to be displayed. If "history" is entered, all history records are displayed. Xhdisp will selectively display records of these types: "vignetting", "exposure", "background", "bkgd", "user". Also, if the specified type is an abbreviation of one of the above, the type is expanded automatically. Thus, for example, "v" will display only vignetting history records.

EXAMPLES

1. Display all history records for the file i296_smrot, a file that was qpcopy'ed and then qprotate'ed.

cl> qpcopy "xdata$snr.qp[pi=(0:7)]" "" snr_small.qp ""
cl> qprotate snr_small.qp "" snr_smrot.qp "" 45.0
cl> xhdisp snr_smrot.qp "history"
