If you use Texture Manager to grab the bitmap you can specify a size in pixels, but not percentage unfortunately. Otherwise, you'll need to create a blank bitmap at the desired size and draw the background into that using scaling.

I don't think so even roTextureManager can handle images larger than 2048x2048. Will have to pre-scale larger images server side.

I assume you mean using
DrawScaledObject(x as Integer, y as Integer, scaleX as Float, scaleY as Float, src as Object) as Boolean
But this function takes either a roBitmap or roRegion and source, it doesn' t take a file as source. In order to use this we need to get the file into bitmap first. So this wont work

Yes, that way, you can scale it, to avoid doing it again and again you can write a method to do it.

function GetScaledImage(path, w, h)
	bitmap = CreateObject("roBitmap", path)
	if bitmap <> invalid
		scaledBitmap = CreateObject("roBitmap", {width: w, height: h, AlphaEnable: true})
		if scaledBitmap <> invalid
			if scaledBitmap.DrawScaledObject(0, 0, w/bitmap.GetWidth(), h/bitmap.GetHeight(), bitmap) = true
				return scaledBitmap
			end if
		end if
	end if
	return invalid
end function

I've done it, so I'm pretty sure it can.

Then I would agree roTextureManager is better way to get and scale images.

Yes, you are correct, that only applies to things less than 2048 which you had figured out already, I should have paid a little more attention.
