viewing 12 bit image file

Post by ZELLIS »

we use 12 bit image files and would love to use XnView to display the imagery but your current version only supports 8 bit files. it sure would be nice to pull up a 2016 x 2016 x12 file format. is this something that can be done?

thanks.

I use XnView to display 16 bits TIFF images (Black&White 16bits and Color 3x16bits) without problem.
Could your provide more info: image format and maybe a sample?

It's probably a RAW format not yet handled by XnView (there are actually many different RAW formats, specific to each system) => what system/camera does it come from?

I won't be able to help you much, but you may try to update this thread next week, as Pierre (author of XnView) is currently on holiday. He usually needs a sample to implement a new format...
(and more people may try to help meanwhile if you make the file available as suggested by Drahken)

:) Hello !

• From your link, I got a file <good> without any extension 8,128,512 bytes… :?
- Please, let me know what that file is exactly, I can't attempt to open it currently, I'll go certainly to a failure… TIA
Note : in XnView, I see only a tiny image 12*14 "24 BPP" :P

I zipped the file to 52KB here. It's a specific "raw" 12 bits grey image that should be displayed as follow:

:? I had the same saved from the forum as PNG 8 BPP which is viewable…

- The RAW file from your ZIP is fancy displayed as a 256*256 24 BPP here…
…while the size is reported as 7.75 Mib (that is correct) :

• Zooming in, you can see "virtual" colours, while the pic might content only "Greys"

would it be difficult to add support for 12bit raw format? is this something you would be willing to implement?

thanks again for a great viewer. :wink:
