TVCHAN 1.0 4.0 Image channel to load with
BCHAN 0.0 1023.0 First frame to show. 0 => 1
ECHAN 0.0 1024.0 Last frame to show. 0 => all
DOCIRCLE -1.0 1.0 <= 0 => reverse direction of
movie at each end
DOCENTER -1.0 1.0 > 0 => use zoom factor FACTOR
and force TV window to be
centered, workstations only
FACTOR 0.0 16.0 zoom factor to use
Use: To rerun a movie or portion of a movie previously loaded
and run with TVMOVIE. During the movie phase, the cursor
X position controls the movie frame rate, button A starts
or stops the movie, button B reverses the direction of
the movie, button C stops the movie (if needed) and
allows color or black and white enhancement, and button D
exits. While the movie is stopped, the cursor X position
controls which frame is displayed. During image enhance-
ment, the cursor X position controls the intercept, the
cursor Y position controls the slope, buttons A or B
switch between color and black and white enhancement,
button C reverses the sign of the slope (b & w only),
and button D returns to the movie mode.
TVCHAN......Image channel to load with the first frame.
Channels TVCHAN+1,... will be used as needed.
0 => channel 1.
BCHAN.......First frame to show (relative to the first
frame in TVCHAN). 0 => 1.
ECHAN.......Last frame to show (relative to the first
frame in TVCHAN). 0 => all.
DOCIRCLE....False (<= 0.0) means to reverse the direction of
the movie each time it hits the end. Else show
BCHAN after showing ECHAN or the reverse.
DOCENTER....If true (> 0), limit the TV window to the size
needed to hold 1 frame zoomed only to a factor of
FACTOR. This is available only on workstations
and can be used to make TVMOVIE run faster.
FACTOR......The zoom multiplication factor: 1 => no zoom, 2 =>
double (linearly) each pixel, 3, 4, 5, ... etc.
FACTORs between 1 and the number of frames across
the full screen are meaningful.
