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).
