Parameter descriptions

VOLFILE

Specifies the full path and file name of the input header (volume) file.

IMGFILE

Specifies the full path and file name of the file that contains the image data to be read.

MTCH

MTCH is an output parameter. Upon completion, CDSH writes the three values reported from the input image on the CD to this parameter.

These values can be used by automated CD-reading procedures.

Details

CDSH reads an LGSOWG source header from CD and prints out a report. Only the LGSOWG CD format is supported.

You must specify the full path and file names for the volume descriptor (header file) and the image data.

The MTCH output parameter contains the number of pixels, lines, and channels read from the CD.

Example

Run CDSH to determine the information of an LGSOWG CD.

from pci.cdsh import *

volfile     =   r'/cdrom/scene1/vol.dat'
imgfile     =   r'/cdrom/scene1/img.dat'
mtch        =   []

cdsh( volfile, imgfile, mtch )
