I notice through some older posts that Cairo is available in FPC. Can anyone give me a head up on how it perform on Windows, and what the easiest way to try it out is?

fpc's cairo canvas is an extension for the GTK2 widgetset and is not generic enough to be used on all widget sets. If you need it on windows you need to work on it a bit ee copy the header translation remove any gtk2 references and replace it with something more generic or windows specific depends on your time and will power.

There is also Luiz Americo's TCairoPaintBox, which I am using with QT on Linux. It has Windows bindings, but I have not tried them at this point.
You can find it at https://code.google.com/p/luipack/ (https://code.google.com/p/luipack/).

Thanks I will try - if not I will try GTK3, and if that don't work I will do it the easy way since this is a C/C++ library :)

Take a look at the following fresh new binding:

Strongly tested under Windows. Linux and other OSs will be available soon.

Why does it have such bad anti-aliasing? Take a look at the first two images - look at the outer edges of the largest black circles. In the 3rd image, look at the text edges.

Probably the clipping mask is 1-bit.
