Color replacing doesn't work [Solved]

[testperson]

Hi,

I tried to replace the color #ffffff by #f7f7f7. But on some of my images it just dont work. I tried it with the batch option of both XnView Classic and XnConverter.

Here is one of those images that failed:

Any ideas why its not working?

The file you uploaded is a 1-bit black and white image, so only colours RGB 000000 and FFFFFF are supported, you would presumably have to convert it to 24-bit depth before replacing FFFFFF...

Yes, that was the issue, thanks a lot
