XnView Software

Thank you

BTW I can't see SVG at all in XNVIEW, so I don't understand your previous answer...

So is this a "ok, this is no good but it is as it is" or is it a "I will have a look at it"?

I did as you said but nothing changed.Maybe you could try it yourself with a transparent PNG? The preview shows the chessboard background but the icons of transparent pngs still have a plain white background so you can't see anything on transparent pictures with white content.

As this option only exists for the picture-view it has only an effect on the preview-image but not on the thumbnails, see attachement.


Settings for picture-preview:

Settings for thumbnails and another view of the problem:

Imageine a transparent PNG containing white Text / symbols.
I can set the background-color of the thunmbnail view, the preview-window and of the detail-view.
By setting a darker color in all views I can easily see the content of the PNG. However in thumbnail-view I just can see a white square ...
