When I paste an image into clip studio paint, the position is shifted.

[ats]

XnView: MP 0.99.6 - 64 bit
OS: Windows10 /64bit

We use the DeepL translation, so we apologize if the meaning of the text is not understood.

<Short description of the problem.>
When I use "Copy to clipbord-image" and paste it into clip studio paint, the position is shifted.

To reproduce:
1. <Step 1>Copy to clipbord-image (Ctrl+Shift+C)" for PNG, BMP, or TGA image data.
2. <Step 2>Paste it into "clip studio paint".


Actual behaviour (bug):
The three pixels on the left edge of the image will be moved to the right edge.

This did not happen when copying "JPG" or "TIF" images.

The problem does not occur when copying from "xnview classic" or "irfanview".

This problem does not occur when pasting into "photoshop", "GIMP", or "MS Paint".

Celsys, the maker of Clip Studio Paint, responded that XnviewMP might be the cause of the problem.

I can't reproduce, you have the problem with all pasted images?

Thank you for your answer.

I checked and it was not all png files.

For example

for example, does not cause the problem.

But

from MP to copy and paste, you will have a problem.

Also, I've checked.
I get an error with png images saved with clip studio paint.(I have attached that image.)
The error does not occur with pngs saved in photoshop or GIMP.

could you send me the file? I don't have a account

Is this OK?

The one with the error is "b31c831f85df63bc1a001b925a2bdca9.png". and "m_52(clipstudiopaintEX).png".

ok, i can reproduce, the problem when pasting 32bits image into Studio Paint. But the clipboard content is correct...

Thanks for your help. I am glad to hear that you were able to reproduce the problem.
However, I don't think it is a fatal bug, so if you can identify the cause, please fix it.

But not sure that the problem comes from XnView MP, the clipboard content is correct

I understand.
I'm going to contact Celsys again.

The answer from Celsys is that they want to know if there is a problem with the different results between Xnvew classic and MP, and why the results are different.

I don't know if I can be of any further help, as this is a very technical topic...
