Painting images using PixelWriter

[Jasper Potts]

Hi,

There will always be at minimum one copy operation because JavaFX runs on two threads. So at the point when you set pixels a copy will be made so it can be safe to access that new copy from our internal render thread. So you can have your own ByteBuffer access from native and every time you call setPixels a copy will be taken for the JavaFX platform to use. So you will need to make sure the content is static during that setPixels (copy) operation.
