NAME
fitstopnm - convert a FITS file into a portable anymap
SYNOPSIS
fitstopnm
[-image
N]
[-scanmax]
[-printmax]
[-min
f]
[-max
f]
[FITSfile]
DESCRIPTION
Reads a FITS file as input.
Produces a portable pixmap if the FITS file consists of 3 image planes
(NAXIS = 3 and NAXIS3 = 3), a portable graymap if the FITS file
consists of 2 image planes (NAXIS = 2), or whenever the
-image
flag is specified.
The results may need to be flipped top for bottom; if so, just
pipe the output through
pamflip -tb.
OPTIONS
The
-image
option is for FITS files with three axes.
The assumption is that the third axis is for multiple images,
and this option lets you select which one you want.
Flags
-min
and
-max
can be used to override the min and max values as read from the FITS
header or the image data if no DATAMIN and DATAMAX keywords are found.
Flag
-scanmax
can be used to force the program to scan the data even when DATAMIN
and DATAMAX are found in the header. If
-printmax
is specified, the program will just print the min and max values and
quit.
The program will tell what kind of anymap is writing. All flags
can be abbreviated to their shortest unique prefix.
