Extracting App view image

[abakoboParticipant]

Is there a way to extract the Data from an image?
It looks like it is stored in a Texture but there are some private stuffs…

With pixmaps I can use pixmap.Data but I’d like to save my screen using the canvas passed to OnRender (something like canvas.RenderTarget.Data)

canvas.CopyPixmap(New Recti(0, 0, canvas.Viewport.Width, canvas.Viewport.Height))

?

example: (press F10 to save capture to your desktop)

Yeah, canvas.CopyPixmap is about it right now. GLES2.0 lets you read backbuffer/write textures but not vice versa. It shouldn’t be too hard to ‘fake’ it though – please post an issue on github to remind me!
