application converts an NDF
to a PBMPLUS
PGM-format file. The programme first finds the brightest
and darkest pixel values in the image. It then uses these to determine suitable scaling factors to
convert the image into an 8-bit representation. These are then output to a simple greyscale
PBMPLUS PGM file.
ndf2pgm in out

The name of the input

ndf2pgm old new This converts the NDF called old (in file
old.sdf) to the
ndf2pgm in=spectre out=spectre.pgm This converts the NDF called
spectre (in file
spectre.sdf) to the PGM file
was written for diagnostic purposes and is included just in case someone finds it useful.
in the data array are replaced with zero in the output PGM file.
