Pasting a selection into other programs works differently in XnView MP

[TimKraft]

xnview, thank you for that amazing program!

I also have an issue with clipboard - can't paste selection nowhere (except Krita).

An example with Skype 8.71.0.49.

Another example with Gimp 2.10.14

I'm using Window 10 Pro
XnView MP Version 0.98.3 64bits (May 6 2021)

It works if you use 'Copy to clipboard>Image'?

Ctrk+Shift+C
It works with Sjype, but not with Gimp

Thank you!

A lot of time has passed and I'm still suffering from this problem. I think I've figured out what the problem is. You should have paid attention to the last point about flushing the clipboard buffer. My guess is that the MP version does not complete the output stream when it saves an image to the clipboard. The problem people are pointing out in this thread happens when this case:

1. Select the cropped area in the MP version.
2. Ctrl+C.
3. Ctrl+V to Discord or Twitter.

However, if you quit MP after copying, the stream completes and you have a right image in the clipboard, and then when you paste it, you can paste the cropped image as intended.

1. Select the cropped area in the MP version.
2. Ctrl+C.
3. Exit the MP version.
4. Ctrl+V to Discord or Twitter.

Just wanted to confirm arngard's observation. After copying image data (in the browser or the viewer), I can only successfully paste the image data into Gimp after closing XnView MP.

I tested with XnView MP v1.7.2 x64 and Gimp 2.10.38

I also changed "Copy to clipboard > Image" to CTRL+c and think it should be default like in any other program. XnView is an image viewer after all, so why not copy image data with the universally known CTRL+c by default?

Copying part of image is buggy
and many more..

the problem is - 'Image content' shall be copied via CTRL+C command (see other apps)
SHIFT+CTRL+C shall be the advanced one with whatever additional stuff

I'd also prefer standard behavior.

Still not working in v1.8.2

Should I report this as a new bug for it to gain attention? This should be rather easy to fix.

i can't reproduce on Windows with gimp 2.10 & XnView 1.8.2. How to reproduce?

Strange that the bug doesn't happen on your PC.

To reproduce:

A) Open any image, select part or all of the image and copy image data.
Paste as new image in GIMP (2.10.38).
=> GIMP shows an error message saying that there is no image data in the clipboard.

B) Now, close XnView MP, and paste as new image in GIMP again.
=> Suddenly, the image data gets pasted correctly.

It seems to only affect GIMP. The image data gets pasted correctly in XnView MP, CopyQ, LibreOffice, Inkscape, KRITA, and paint.net.
I assume that GIMP might adhere more strictly to standards, or fails to interpret certain data as image data. But since closing XnView fixes the problem, XnView must be doing something to the clipboard content when closing that it should have done right away. (see this comment: viewtopic.php?p=187323#p187323)

I'll try to analyse the clipboard content to find out what happens when closing XnView. But I need to find out how and what software I can use...


Edit: I suspect that GIMP is at fault here. Searching for 'GIMP "no image data in the clipboard"' does show that it is a known problem. But ... I don't know if they can fix it.

Okay, I downloaded "Free Clipboard Viewer" and copied image data in XnView MP, LibreOffice Draw and a Windows screen shot:

Copying image data in XnView MP does store a lot of different objects in the memory, but so does LibreOffice. However, the image copied from LibreOffice can be inserted as image in GIMP without problems.
Copying in XnView Classic looks like taking a screen shot with the Prnt key.

A) Open any image, select part or all of the image and copy image data.
Paste as new image in GIMP (2.10.38).
=> GIMP shows an error message saying that there is no image data in the clipboard.

I've tried again, and no issue
To copy image data, you use Edit>Copy?

B) Now, close XnView MP, and paste as new image in GIMP again.
=> Suddenly, the image data gets pasted correctly.

it's normal, due to a Qt bug, the data are saved in another way in clipboard

[m_seitzz]

Again, strange that it doesn't affect everyone.

I tried both "copy" and "copy image content", and both are not working for GIMP.

Idk, maybe it's best to just forget about this. If you can't replicate the bug (in GIMP!), there is no way fixing it. But thanks for looking into it!
