Export of PNG 16 bit is not 16bit (Gradient Banding and hard edge artifacts in export image)

Steps to reproduce:

  • open Inkscape
  • Make a Gradient e.g. in Grayscale
  • Export a PNG 16 bit and/or 16bit gray
  • Zoom in in exported PNG to better see the issue

What happened?

Analyse the PNG > the Gradient has Banding and is not 16 bit quality The gradient also has strange artifacts and is jagged.

What should have happened?

The PNG 16 bit should be 16 bit quality and gradients have less banding or artifacts
