@Dali - thank you very much! Much easier to read like that. And it’s a shame users must perform such inversion, as manuals are not provided for daylight reading and printing (NDSP is so “manly and metal tough”, outch).
@Cheems - all the pages are white. Some of them contain tables, which background could not be inverted. Those you see as black.
Best!
I don’t get it ??? Every time I download this file, no matter which of a dozen programs I use to view it, it is still white text on a black background ???
damn thats weird
Can someone post the actual inverted file?
it´s on the above post by Dali, but for some reason we are not able to see it inverted
I checked that link but appears you have to sign up to access.
the link has expired. WeTransfer shares have a limited lifetime. Somebody has to re-upload it, maybe in a more permanent way
