[BUG] Can't always paste images from AppendClipboardImage [message #52282]

(Windows 7 & 10)

I can paste images that were copied to clipboard using AppendClipboardImage into the Gimp image editor or MSPaint, but I can't paste them into Slack or gmail.
I can however paste images copied from other sources into Slack or gmail, so the problem is not (at least entirely) on their end.

The specific example I am looking at is the ScatterCtrl library calling WriteCipboardImage.

Testing some more,

it works in internet explorer, just not in Chrome.

I think the issue may be that Chrome and also the Slack app don't accept the CF_DIB clipboard format (though this is hard to actually find out).

So I guess this is more of a feature request (to implement a clipboard format that is more commonly accepted) than it is a bug.

Yeah, but what is more common than CF_DIB? Thats the basic format for rasters after all, is not it?

I don't know, unfortunately. I tried to do some research on it yesterday, but it was not that easy. Apparently there are also CF_DIBV5, CF_BITMAP and something called a "png" format for clipboard, but I don't know why CF_DIB doesn't work always, and I don't know what other formats would work in e.g. chrome.

All I know is that it would be very useful to be able to paste graphs directly into slack or emails.

I have tried adding png image format to clipboard, but that does not seem to fix the issue. My guess is that this is not format related, what the reason is I am completely clueless for now....
