XMOVIE - image one or more frames of a uniformly sampled function f(x1,x2)

xmovie n1= n2= [optional parameters] <fileoffloats

X Functionality:
Button 1 Zoom with rubberband box
Button 2 reverse the direction of the movie.
Button 3 stop and start the movie.
q or Q key Quit

Required Parameters:
n1 number of samples in 1st (fast) dimension
n2 number of samples in 2nd (slow) dimension

Optional Parameters:
d1=1.0 sampling interval in 1st dimension
f1=0.0 first sample in 1st dimension
d2=1.0 sampling interval in 2nd dimension
f2=0.0 first sample in 2nd dimension
perc=100.0 percentile used to determine clip
clip=(perc percentile) clip used to determine bclip and wclip
bperc=perc percentile for determining black clip value
wperc=100.0-perc percentile for determining white clip value
bclip=clip data values outside of [bclip,wclip] are clipped
wclip=-clip data values outside of [bclip,wclip] are clipped
x1beg=x1min value at which axis 1 begins
x1end=x1max value at which axis 1 ends
x2beg=x2min value at which axis 2 begins
x2end=x2max value at which axis 2 ends
fframe=1 value corresponding to first frame
dframe=1 frame sampling interval
loop=0 =1 to loop over frames after last frame is input
=2 to run movie back and forth
interp=1 =0 for a non-interpolated, blocky image
verbose=1 =1 for info printed on stderr (0 for no info)

Optional resource parameters (defaults taken from resource database):
windowtitle= title on window and icon
width= width in pixels of window
height= height in pixels of window
nTic1= number of tics per numbered tic on axis 1
grid1= grid lines on axis 1 - none, dot, dash, or solid
label1= label on axis 1
nTic2= number of tics per numbered tic on axis 2
grid2= grid lines on axis 2 - none, dot, dash, or solid
label2= label on axis 2
labelFont= font name for axes labels
title= title of plot
titleFont= font name for title
titleColor= color for title
axesColor= color for axes
gridColor= color for grid lines
style= normal (axis 1 horizontal, axis 2 vertical) or
seismic (axis 1 vertical, axis 2 horizontal)

Color options:
cmap=gray gray, hue, saturation, or default colormaps may be specified
bhue=0 hue mapped to bclip (hue and saturation maps)
whue=240 hue mapped to wclip (hue and saturation maps)
sat=1 saturation (hue map only)
bright=1 brightness (hue and saturation maps)
white=(bclip+wclip)/2 data value mapped to white (saturation map only)

Notes:
Colors are specified using the HSV color wheel model:
Hue: 0=360=red, 60=yellow, 120=green, 180=cyan, 240=blue, 300=magenta
Saturation: 0=white, 1=pure color
Value (brightness): 0=black, 1=maximum intensity
For the saturation mapping (cmap=sat), data values between white and bclip
are mapped to bhue, with saturation varying from white to the pure color.
Values between wclip and white are similarly mapped to whue.
For the hue mapping (cmap=hue), data values between wclip and bclip are
mapped to hues between whue and bhue. Intermediate hues are found by
moving counterclockwise around the circle from bhue to whue. To reverse
the polarity of the image, exchange bhue and whue. Equivalently,
exchange bclip and wclip (setting perc=0 is an easy way to do this).
Hues in excess of 360 degrees can be specified in order to reach the
opposite side of the color circle, or to wrap around the circle more
than once.

The title string may contain a C printf format string containing a
conversion character for the frame number. The frame number is
computed from dframe and fframe. E.g., try setting title="Frame %g".
