Hi guys I wanted to know you point of view. I fall on TextSqkLink and TextSqkProjectLink that it would be good to remove them. What your point of view on that? Stef

The only thing which is required to wire things up. Here is components which need to be merged (to work together): - SurfacePlugin & HostWindowPlugin on VM side - DisplayScreen class need to be refactored to create new host window and ask for its surface (which in own turn should be registered by HostWindowPlugin using SurfacePlugin interface). There are also an example in platforms/Cross/plugins/ExampleSurfacePlugin , how to create & register own surface and how to use it at language side. So, we really can throw out almost all windowing stuff from core VM, leaving HostWindowPlugin to handle things. Initially, i guess, that most changes will affect the Display var and DisplayScreen class. For headless mode , a Display could be replaced by NoDisplayScreen - which simply ignoring all calls LazyDisplayScreen - which sits in Display global var until first drawing attempt, and then creates a window and replacing itself by working DisplayScreen. -- Best regards, Igor Stasenko AKA sig.

The FreeType plugin seems to work great. I notice that you have used FreeType 2.3.7 - that's good, the previous plugin used 2.2.1 which is quite old now. However, the sub-pixel anti-aliasing isn't working. This can be tested by evaluating ... FreeTypeSettings current clearBitBltSubPixelAvailable; bitBltSubPixelAvailable It answers true if the new BitBlt combination rule 41 is present and working; false otherwise. Did you install FreeTypeBitBltSimulation.1.cs (http://www.zen61439.zen.co.uk/bak/bitBlt_plugin_enhancements/FreeTypeBitBlt…) into your VMMaker image? If you did, then it is possible that the changeset isn't compatible with the latest VMMaker, and I'll look into it. Cheers, Andy > > > -- > Best regards, > Igor Stasenko AKA sig.
