112 Operation of The Camera
− horizontal lines for aspect ratios >1.78 (e.g. 1.85): [1-
(1.78/Aspect)]/2=distance from bottom or top
− vertical lines for aspect ratios <1.78 (e.g. 1.33): [1-
(Aspect/1.78)]/2=distance from left or right
XML example
The best way to understand the frame lines system is by looking at an
example. The following example describes a frame lines file for a 2.35
centered aspect ratio inside the cameras 1.78 recorded image.
<?xml version="1.0" encoding="UTF-8"?>
<!-- NOTES:
All widths are in pixels.
All colors can be one of: black, white, or user.
If you select user, the color can be changed through
the user interface.
You can add as many lines as you like. Lines are
defined by giving 3 distances from the border.
So if you specify top, left and right it will
be a horizontal line with the given distance
from left, right and from the top.
The values are in the range [0, 1], where:
0 is at the edge
1 is on the opposite edge
So specifing 0.4 from left is the same as 0.6 from right.
