Re: [Guidolib-devel] new engine version 1.6.5

[Dominique F. <fo...@gr...>]

Hi Michael,

The GDI an GDIPlus devices are quite old. I didn’t checked how it works on the latest Windows OS.
In addition, there is no application to test on the repository. I suggest to test with a minimal application in order to find what’s going wrong.
Regarding Direct2D, I’m not aware of any implementation. It should not be difficult to build one, you have only to implement the VGDevice, VGSystem and VGFont interfaces.
