XnView: MP 0.97.1 64bits
OS: Windows 10 64bit build 19042.572

Convert image to HEIC/HEIF look succes (no errors or messages), but result in heic file is 0 bytes.

Effect: Saved file in HEIC/HEIF is 0 bytes.

To reproduce:
1. Open any PNG or JPG image (I've tested only them).
2. File - Save as (Ctrl + Shift + S).
3. Select HEIC - HEIF, save the image.

4. Status bar shows 0 bytes. Windows Explorer shows 0 bytes.

i have no problem to save HEIC format, do you have the heic.dll (2020) in plugin folder?

[chencher]

No, heic.dll is missing, but there is heif.dll:

Before I discovered the described problem, I updated XnView MP from 0.97.0 to 0.97.1 using installer from site.

No, heic.dll is missing, but there is heif.dll:

I don't understand, do you have it?

[chencher]

Yes, but heif.dll, not heic.dll

[xnview]

Yes, but heif.dll, not heic.dll

Oh sorry, yes heif.dll. for reading, no problem?

[chencher]

Oh sorry, yes heif.dll. for reading, no problem?

Yes, reading is ok.

[xnview]

ok, currently heif.dll is only used for loading. The HEIC store component is used to save.

So how can I save heic files with xnview? What is store component and how do I install it?

you need to install HEIF plugin from Windows store

[rutra80]

I do have it. Unfortunately for some reason saving doesn't work system wide, in Paint neither.

EDIT: ok I found out that it is also needed to install HEVC, which isn't free. Maybe it would be worthwhile to implement HEIC saving in XnView natively?
