TVPSEUDO: Verb to activate three types of pseudo-color displays
TVLEVS 0.0 32768.0 Peak intensity at OFM
Instructions will appear on terminal.
Use: Interactive function to pseudo color the sum of all visible TV
images. Three methods are available.
Press Button A for "RGB triangles" formed by linearly
decreasing the first color from max to min while increasing the
second color from min to max. Then the second color is
decreased from max to min while the third color is increased
from min to max. The cursor X position sets the input intensity
which separates these two regimes. The cursor Y position sets
the color correction power gamma (0 to 4). Hit button A to
cycle the selection of the color order: BGR, GRB, RBG, RGB,
GBR, and BRG.
Hit button B to form colors from circles of maximum saturation,
fixed intensity, and varying hue in the hue - intensity -
saturation space. The cursor X position sets the number of
circles (1 - 8) to span the range of intensities from 0 to
TVLEVS-1. The cursor Y postion sets the starting hue.
Press button C to get a choice of color contours as fixed
sequences of colors. The choices are 9-level sequence designed
by Renzo Sanchisi and the AIPS programmers, an 8-level sequence
suggested by Lincoln Greenhill and designed by the AIPS
programmers, a 10-level sequence from GYPSY, and an 8-level
and a 64-level (spectrum) sequence from IMPS. The cursor X
position sets the intensity at which contours begin, while the
cursor Y position sets the range of intensities actually
contoured. Intensities below the range are given the starting
color and intensities above the range are given the ending
Press button D to exit.
TVLEVS....Specifies the maximum intensity expected for the sum of
all visible, overlapped images. Has always been n x max
in one image (now 2046). < 2046 => 2046.
