I'm watching a bike race with Xastir and the Tiger 2008 maps. There
are lots of overlapping tracks. It got me thinking--the whole thing
would be a lot easier to read if there was anti-aliasing on the maps,
tracks, and text, and semi-transparency on the tracks. What would it
take to accomplish this? I haven't poked around in the GUI code at
all. Does Xastir already use a library that supports these options?
Anti-aliasing: I don't believe any of us have ever looked into
that. Feel free and report back? hi hi
I looked into it once. One option, the quick one, was to double the
height and width of the drawing canvas, the use ImageMagick or
Graphicsmagick to scale it down.
Another option would be to find a graphics library that supports the
same kinds of primitives as Motif (not hard) and also supports
anti-aliasing.
I found one once, but can't remember now. My coding isn't/wasn't good
enough to integrate it into Xastir. But basically you would replace all
the line/poly instructions with calls to the alternate functions, them
load the resulting canvas into the display window.
