1. Using XNView 2.49.3 (May 15 2020) on Windows10.
2. "B&W TIFF image(CCITT G4 compression)" changed to LZW compression(8bit color) after rotation.
3. How can I get "CCITT G4 compression TIFF image" after rotation ? When I rotate by 90 degrees, this does not happen.
4. [Tools] > [Options] > [Read/Write] > [Write] > [TIFF] settings are below:
Colour compression --> LZW
Binary compression --> CCITT G4
All checkbox --> off
regards,
TIFF Compression after rotation

Re: TIFF Compression after rotation
When you rotate image, image is no more in 1 bit per pixel, so you need to convert it before
