It requires headers and libraries for Boost, gtkmm, Mozilla or

-gtkmm 2.2.12, Mozilla 1.7.8 and expat 1.95.8 but it may well work with

+XULRunner, and expat. I am currently building and testing it with

I use Debian Linux and have not yet attempted to build it on other
systems, but it should work on most modern Unix-like systems.

Bugs
----
-Under Mozilla 1.7, VideoLink sets the assumed screen resolution to
-40 dpi, which I reckon to be the average resolution of a standard
-definition TV display. This should mean that text with a font size
-expressed in millimetres or points will appear around the specified
-size. Unfortunately this setting has a different effect under
-Mozilla/XULRunner 1.8:
-
-Mozilla Assumed Requested Actual size
-version resolution size (pixels) (inches)
- (dpi)
-
- 1.7 default:96 20 px 20 0.5
- 1.7 default:96 36 pt 48 1.2
- 1.7 40 20 px 20 0.5
- 1.7 40 36 pt 20 0.5
- 1.8 default:96 20 px 20 0.5
- 1.8 default:96 36 pt 48 1.2
- 1.8 40 20 px 48 1.2
- 1.8 40 36 pt 48 1.2

-From version 0.10, until I have a proper solution, VideoLink will not
-set the assumed screen resolution under Mozilla 1.8. I must advise
-against using font sizes in millimetres or points since they will vary
-between browser versions.
+VideoLink should set the assumed screen resolution to 40 dpi, which I
+reckon to be the average resolution of a standard definition TV
+display. This would mean that text with a font size expressed in
+millimetres or points will appear around the specified size.
+Earlier versions of VideoLink did this when built to use Mozilla 1.7.
+Unfortunately the resolution setting in Mozilla 1.8 actually affects
+measurements in pixels and not measurements in millimetres or points!
+The assumed screen resolution is always 96 dpi.
+
+Please specify measurements such as font sizes in pixels because
+measurements in millimetres or points are liable to change if and when
+I can override the assumed screen resolution again.
