Moz2D is used in Firefox to render webpages. For us it means that it supports all latest web features (concerning graphics) and allows us to finally implement the whole SVG standard.
> "Why would one use it rather than the other existing Pharo libraries/wrappers?" As far as I know there are two 2D libraries in Pharo: BitBlt and Athens (backend Cairo). Obviously BitBlt does not fit all our needs :) Athens is nice vector graphics abstraction. However, it does not support shadows, filters, clipping by arbitrary path, only works in global coordinates and has primitive text rendering. All those features were not necessary at the time it was developed. Another problem is statefullness of Athens (state is shared between draw operation) which does not fit so good when it comes to the rendering of an element tree. There is a modern trend to move from statefull to stateless frameworks. It is almost impossible to extend Athens without breaking user applications that use it. So, Sparta is Athens2 that adds support of all mentioned features. It is inspired and based on amazing work of Igor Stasenko. In Pharo we have bindings to Cairo. Which is old, lacks on features and no more maintained so good as it was before. To be performant we need to use native backends on every platform: D2D1 on Windows, X11 on Linux, CoreGraphics on Mac. Just imagine how much work is needed to implement bindings for every mentioned backend :) And do not forget that CoreGraphics is Object-C and can not be directly called through FFI, it has to be wrapped in C first... With Moz2D we get them all out of box for fee :) Cheers Alex On Sep 5, 2016 16:28, "Sean P.
