How did you build/get freetype.dll? If it was built using Visual Studio,
freetype.dll might have been linked against a newer C++ runtime such as
msvcr71.dll that is not shipped with windows by default. You clearly
need to deploy C++ runtime libs as well with your product.
You may benefit from such tool as a dependency walker
(https://en.wikipedia.org/wiki/Dependency_Walker).
On linux you can just use ldd.
Hope this helps,
Stefan

It has more features than GDI font support and the quality is better too.
Is it the fonts causing the dependency then? I have freetype.dll included in
the directory with my programs, do I need to include other files / dlls if I
want them to run without installing anything?
the programs I am getting the dependency issue with are based on and including
Graeme's original sample program Agg2DColsole.dpr , they use:
Ptcgraph,
Ptccrt,
Sysutils,
Fpimage,
Fpwritepng,
Agg_2d,
Agg_Basics

In my experience, the one dependency that AggPas has potential to fail
may be related to the freetype library. If you plan to run your app on
windows only, then you can turn freetype off and AggPas will happily
use windows font libraries. Search for the AGG2D_USE_FREETYPE define
and comment it out.
Correct, though even font support is optional in AggPas. So if you don't render
text via AggPas, it has zero dependency - everything is done in pure Object
Pascal code.
