Defining Display Maps |
Map configurations are used to define the display appearance
for an individual scene, or map, in the entire
sequence. The following sample
illustrates and explains each of the components of a map
display. It also shows how the components are defined in the
configuration file. Note that the elements of the map configuration
must be in the order presented. Single-line comments may be
used with the
This example is based on the fourth map
in the UWTV implementation.
In the Traffic Channel installation directory, it is the
TrafficMaps\hovEast.txt file
# TrafficChannel map layout/configuration
# Definition to display HOV traffic data on the right side of
# the display and video on the right.
# number of video effects
2
# The Genie effect files, start times in msec, time in msec
# until running reverse effect (0 if no reverse effect)
# Reversed effect lets you run previously loaded effect in reverse, after an interval
# For instance, zoom video out from map, wait, then back into map
c:\TrafficChannel\Effects\pagetrn4.eff 5800 0 # transition between maps
c:\TrafficChannel\Effects\WestWipe.eff 1000 0 # swoosh out video on layer 2
# Map origin:
# Origin is in the screen coordinate system, with a resolution
# of 640x480 pixels, and is used
# to adjust the relative position of the segment display and the
# components that are displayed relative to the segments

#
# Color Table Definition
# The color table must contain 16 entries numbered 0-15. Each
# color table entry is used to lookup a given object on the display.
# When changing color definitions verify that the new selections
# are 'NTSC safe' by previewing a sample on a vector scope
# and waveform analyzer.
