[mapserver-dev] Some questions to AGG and GD rendering

[Kai Behncke]

Hello Mailinglist,
in some weeks I held a presentation about MapServer 5.0.0 at the German FOSSGIS-conference and some points I find still difficult.

I have some questions to AGG and GD-Rendering and I please you to give me some hints because I couldn`t figure it out with the online-documentation or the mailinglist archives.

Is it right that even if I use the following output:

OUTPUTFORMAT
 NAME 'AGG'
DRIVER AGG/PNG
IMAGEMODE RGB
END

the GD library is used for LABELS, Textpositioning and Rasterlayers ?

If I don`t use:
OUTPUTFORMAT
 NAME 'AGG'
DRIVER AGG/PNG
IMAGEMODE RGB
END

is then nevertheless the command ANTIALIAS TRUE is ignored?

What about STYLES and SYMBOLS, is AGG used for them generally (even if I don`t put:
OUTPUTFORMAT
 NAME 'AGG'
DRIVER AGG/PNG
IMAGEMODE RGB
END
??

Or is GD used generally? In my tests I could`t figure it out.....

It is said that AGG and GD are combined.

For which objects GD is used?
When is AGG used?

Is it right, that AGG renders slower than GD?




Thank you very, very, very much, Kai
