DirectDrawGraphicsMBS

I just discovered this , although its been around since 2020
DirectDrawGraphicsMBS(g) takes a ‘graphic’ as a parameter
When I try to use it in Xojo 2015 on Windows, I get an unsupported operation error

The example uses BitmapforCaching to get a picture, to get a graphics object

dim p as Picture = BitmapForCaching(me.Width, me.Height)
dim g as graphics = p.Graphics

I don’t use BitmapForCaching in 2015 …

Is DirectDrawGraphicsMBS incompatible with Xojo 2015…( the docs don’t mention any minimum Xojo level)
Is it perhaps conflicting with GDI+ ?

Your Xojo version may be too old.
The plugin only works if the graphics is backed with a picture using DirectDraw surface and then provides additional functionality.
