16-bit per channel PNG export
I'm using Inkscape to generate heightmaps and bumpmaps that I use in Blender.
The problem I have is that 8 bits per channel gives my very bad quantization (stairstep) on the heightmaps.
The color depth is simply not enough.
Is it possible to export a higher color-depth bitmaps out of innkscape?
16- bit per channel for PNG would totally solve the issue for me, but how do I do this?
In theory I could overcome this limitation by oversampling with dither (like one can do in audio):
1. Add a thin layer of noise overlay in Inkscape that'd produce dithering on the gradients - adding more "sub bit" information.
2. Export to at least 2x resolution - we need more pixels to make use of the dithering.
3. Load in a program that supports higher bit depths (like Krita)
4. Scale down the image, avaraging the pixel values and save to a 16-bit per channel PNG.
This would be very tedious and resource hungry and I would very much love to just be able to export a 16-bit per channel PNG form Inkscape.
An option to export a Grayscale image with higher bitdepth would also be great to save some diskspace.
