NAME

dcvtob - convert double complex vfft to complex, float and byte formats  

SYNOPSIS


dcvtob    [-max_in #] [-C] [-F] [-fflip] [-flip] [-nonscale]
          [-regular] [selfscale] [<] input [> output]
 

DESCRIPTION

dcvtob converts an image whose format is higher than floating point to a specified output format. The input types are in HIPS, FITS, and RLE, and the output is HIPS. If input is double, double complex, or float complex, the output can be either byte or float format. Also complex format can be converted to spectrum format (as in flipquad(1)). If the input is in VFFT format, the output is a spectrum in float or byte format. It can be converted without flipping quadrants by using the -r option, or to complex format by using -C option.  

OPTION DESCRIPTION

-C
convert VFFT to complex.
-F
output float format. The default is byte output.
-div #
scale factor for automatically scaling output value up.
-fflip
do fast quadrant flip on regular complex format for viewing only.
-flip
do regular quadrant flip on regular complex format.
-m #
set maximum input threshold at #
-nonscale
output nonscaled conversion.
-r
output original picture, not flipped.
-s
re-scale for each frame (regularly, use scale factor in the first frame).
