fitstopnm - convert a FITS file into a portable anymap
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
flag is specified.
The results may need to be flipped top for bottom; if so, just
pipe the output through
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.
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.
can be used to force the program to scan the data even when DATAMIN
and DATAMAX are found in the header. If
is specified, the program will just print the min and max values and
can be used to force
the program to produce an ASCII portable anymap.
The program will tell what kind of anymap is writing.
All flags can be abbreviated to their shortest unique prefix.
FITS stands for Flexible Image Transport System. A full description
