HELP SECTION
TVBLINK
Type: Verb
Use: To compare images on 2 planes of the TV by blinking them.
While blinking: the cursor X position controls the blink rate,
the cursor Y position controls the proportion of time spent on
each plane, button D causes the verb to quit, and Buttons A, B,
and C cause the blinking to stop and an interactive image
enhancement (just like TVTRANSF) to begin. Button A selects
channel A and button B selects channel B to be enhanced.
Button C specifies that both channels are to be enhanced at the
same time (on TVs which support split screen). During the
enhancement, the cursor X position controls the intercept and
the cursor Y position controls the slope of the (linear)
transfer function. Buttons A and B may be used to select
enhancement of channels A and B, resp. Button C will switch
the sign of the slope and Button D will return the verb to the
blinking mode. Instructions to remind you of these things will
appear on your terminal.
Adverbs:
TVCHAN.....Selects TV channel to be "channel A"
TV2CHAN....Selects TV channel to be "channel B"
If either are out of range, 1 and 2 are used. On TVs
which support split screen, channel A will appear on the
left (or top) half during enhancement functions.
