New Feature

How would you describe the priority of this feature request

Nice to have (e.g. Adoption is possible, the feature will enhance the use-case even more).

Please provide a clear description of problem this feature solves

nvImageCodec includes the png decoder, how about the encoder counterpart?

Feature Description

nvImageCodec includes the png decoder, but lacks the encoder counterpart. The libpng encoder costs a noticeable time in my project, i don't find any existing solutions. It will be nice that nvImageCodec supports the png encoder.

Describe your ideal solution

a gpu accelerated png encoder

Describe any alternatives you have considered
