Is there any raw image viewer which can view 10/12 bit packed data formats?

Question

Hello,

I have some images in raw RGB and raw YUV data format having 10 and 12 bit depth. i.e. each R,G,B or a Y,U,V is 10/12 bit unpacked format

1.) Is there any image viewer which can view these files.

2.) Also is there any data to view if the data is in packed format? i.e. no zero padding of 6/4 bits after 10/12 bits of data?

Thank you.
