display this help and exit
.TP
\fB\-v\fR, \fB\-\-verbose\fR
verbose operation
.TP

X center coordinate
.TP
\fB\-y\fR, \fB\-\-y\fR=\fI\,N\/\fR
Y center coordinate
.TP
\fB\-\-x0\fR=\fI\,N\/\fR
X corner coordinate
.TP
\fB\-\-y0\fR=\fI\,N\/\fR
Y corner coordinate
.TP
\fB\-r\fR, \fB\-\-rows\fR=\fI\,N\/\fR
number of rows (height)
.TP
\fB\-c\fR, \fB\-\-columns\fR=\fI\,N\/\fR
number of columns (width)
.TP
\fB\-\-all\fR
extract a cutout of the same size as the input image
.TP
\fB\-\-linear\-scale\fR
output in linear scale [default]
.TP
\fB\-l\fR, \fB\-\-log\-scale\fR
output in log scale
.TP
\fB\-s\fR, \fB\-\-sqrt\-scale\fR
output in square root scale
.TP
\fB\-e\fR, \fB\-\-histeq\-scale\fR
histogram equalized output
.TP
\fB\-\-asinh\-scale\fR
asinh equalized output
.TP
\fB\-i\fR, \fB\-\-invert\fR
invert output colors
.TP
\fB\-\-palette\fR=\fI\,name\/\fR
output palette name (png output only)
.TP
\fB\-\-factor\fR=\fI\,value\/\fR
multiply image by value
.TP
\fB\-\-rate\fR
scale image by exposure time factor
.TP
\fB\-\-autoscale\fR=\fI\,percent\/\fR
percent of histogram to include
.TP
If percent is a single value it is interpreted as
the percentage of the histogram to include.
If percent is two values separated by a comma it
is interpreted as the lower and upper bounds
of the histogram to include (eg. \fB\-\-autoscale\fR=\fI\,1\/\fR.5,98.5)
.TP
\fB\-\-autoscale\-min\fR=\fI\,percent\/\fR
lower bound percentage of histogram to include
.TP
\fB\-\-autoscale\-max\fR=\fI\,percent\/\fR
upper bound percentage of histogram to include
.TP
\fB\-\-min\fR=\fI\,value\/\fR
image value to use for scale minimum
.TP
\fB\-\-max\fR=\fI\,value\/\fR
image value to use for scale maximum
.TP
The value for \fB\-\-min\fR or \fB\-\-max\fR may be either one value to
be used for all images (eg. \fB\-\-min\fR=\fI\,0\/\fR), or one value for
each image separated by a comma (eg. \fB\-\-min\fR=\fI\,0\/\fR,0,0)
.TP
\fB\-\-red\fR=\fI\,file\/\fR
filename to be used in red channel of color image
.TP
\fB\-\-green\fR=\fI\,file\/\fR
filename to be used in green channel of color image
.TP
\fB\-\-blue\fR=\fI\,file\/\fR
filename to be used in blue channel of color image
.TP
\fB\-\-zoom\fR=\fI\,factor\/\fR
zoom input image by positive multiplicative factor
.TP
\fB\-\-align\fR
use WCS information in header to align images
.TP
\fB\-\-compass\fR
add a WCS compass to the image
