Hey Guys ,

I want to program a function that takes the pixels of a Graphics window and save the Pixels into a .Png Format. How would I program that?

I think this is what you might be looking for?

Import BRL.PNGLoader
'
'
Function savescreenshot()
	'Draw graphics
	Flip
	Local file:String = RequestFile("Save", "File (*.PNG):PNG", True, AppDir + "//data")
	Local pixmap:TPixmap = GrabPixmap(0, 0, 800, 600)
	SavePixmapPNG(pixmap, file)
End Function

One thing that is easy to forget is t make sure you call that after everything is drawn for that frame, or else you may get only a partial screenshot.
