I like Xara quick composing toolset very much. My problem I need to work with 16 bit grayscale depth images and more advanced blending math.

So I wonder is there a way to export bitmaps from Xara keeping just same "fill" schema so I could replace the bitmap sources with 16 bit originals in 3d party soft?. As a "smart objects" in Photoshop or maybe just as bitmap layers with blurred vector masks in Aphinity PHoto/Designer, maybe as placeholders in Photoline, any other soft ?.

Ideally I would prefer to export into Affinity Designer since it has all necessary blending math and 16 bit support. I hoped I could do it with svg but looks like the feathering makes it impossible. Any workaround?
