I have a TIF, 300x300 dpi, approx. 18.000 x 13.000 pixel, 680 MB, NO compression.
Then I coverted it with XnShell to TIF, LZW. The result:
TIF, 300x300 dpi, approx. 18.000 x 13.000 pixel, 740 MB, LZW compression.
Bug or feature?
Regards
Peter

Re: XnShell creates LZW with increased filesize
I guess it's a truecolour bitmap. Try using LZW+Predictor or ZIP (deflate) compression instead.
