Parameter descriptions

FILE

Specifies the name of the PCIDSK from which to extract the metadata. The XML file to receive the metadata will be created in the same directory as the PCIDSK file, have the same basename as the PCIDSK file, and have an "xml" extension.

Details

METAOUT reads image metadata (a set of name-value pairs) from a specified PCIDSK file, reformats the metadata into an XML document, and writes the data to a newly-created XML file.

METAOUT creates the XML file in the same directory as the input PCIDSK file, using the same base name as the PCIDSK file. The XML document is given an "xml" file extension. If a file of this name already exists, the new file overwrites the existing one.

The schema for the XML document is stored in the file $PCIHOME\\etc\\PCIImageMetadata.xsd. Note that only certain metadata items stored in the PCIDSK file are output to the XML document. It is possible that these may not include all of the items specified as mandatory by the schema. Also note that only the tags specified in the schema are exported; this does not necessarily include all of the metadata in the PCIDSK file.

Example

Export image metadata from cuprad.pix.

from pci.metaout import metaout

file	=	"cuprad.pix"	# PCIDSK file name. "cuprad.xml" will be created
# and the image metadata written to it.
