TIF: XNView-Compression: double size as other software

Postby Peter2 » Fri Oct 20, 2017 7:45 am

I have a TIF, 257 colors, 406 MB uncompressed.

When I use "LZW compression" with

- XNview 2.42, I get a file with 3.6 MB
- another software, I get 1.1 MB file

When I compare both results, they seem to be the same: size, color, DPI, compression, .....

Where is the difference?

Thanks Pierre

but for the user, the result - beside the filesize - is the same? DPI, colors, size, quality, ..
