white letters on black on mac

[andrash]

Hy,

I've downloaded xnview to my mac. I use xnview for working on black and white binary files. I need to adjust the settings for me so that there would be high zoom quality when I "reduce and enlarge". In this case my black letters on white turn to white letters on black background. What should I do? (in the windows version I do not have this problem. Thank you very much, andrash

Could you send me a sample file?
