TIF: XNView-Compression: double size as other software

[Peter2]

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?

Other software use different Predictor
