XnView Software

How can I know which options are available when saving a file ?

I explain : If I want to save a JPEG file I have compression and quality options to set, but what about others formats ?

Compresion generally is not used with a BMP file, I would not like to show a compression option for a file format which does not need it ? What would be thinking the user about such software ?

Is there an other up to date help file ?

What are the filters options ?

Thanks

Yes, currently it's not easy. You must see in XnView what is used

no

What are the filters options ?

Which filter?
