TIFF images always saved in 8bit format

Hello all,

 

It appears the software saves any TIFF image with 8bit quantification, regardless the bit depth of the input image. This means it will overwrite and discard any depth information of TIFF images with high depth resolution (e.g. 16 bit TIFFs). It seems to occur in all situations, opening and saving without any image operations would produce this result.

 

Can somebody please confirm? 

Why is this happening?

Is there a way to circumvent this?

 

Thanks

Wicher

You mean 8-bits or 16-bits per pixel component? 32-bit or 64-bits total?

 

Paint.NET doesn't support 64-bit images. If you're loading a 64-bit image it will be truncated to 32-bits.

Okay, 16-bit per component and grayscale ... so there's only 1 component, not 3 (red, green, blue) or 4 (red, green, blue, alpha)

 

When you open this in Paint.NET, it will be truncated to 8-bit grayscale and converted to 32-bit color (8-bits per component, red, green, blue, alpha). It will then save as a 32-bit image (8-bits per component, red, green, blue, alpha).

 

TIFF support in Paint.NET is minimal. In general, I recommend not using TIFF if you can avoid it. It's kind of a weird, old format that was designed for use by scanners. It supports multiple pages and isn't really a good fit for Paint.NET's layer-based paradigm.
