Large icon view not using 256px png

Hi,

Love this project and how easy it makes embedding Windows resources.

I might be hitting some really obscure Windows bug, but for some reason my 256px icon embedded with go-winres is not being displayed at full resolution (ie. when using (Extra) Large icons in Explorer).

You can see the comparisons with go-winres here in Explorer using Extra Large icons:
Capture

My winres/ folder here: https://github.com/optix2000/totsugeki/tree/v0.2.0/winres
Running Windows 10.0.19043.1110

I've even tried adding all the "required" sizes (16px, 32px, 48px, 256px) to no avail. https://github.com/optix2000/totsugeki/tree/16xicon/winres

Is there some limitation or option that needs to be set for the 256px icon to be used at full resolution?

Hello,

Thanks for filing this bug report.

There seem to be a bug because of the original size not being 256x256 but 256x215.
To fix your icon, you can resize the picture to 256x256.
Then, I suggest you write "0000": "icon.png" instead of "0000": [ "icon.png" ] for better quality:

I'll try to find some time today to fix the bug.
Thanks again.

Alright, Explorer only supports square icons with the required sizes from your link. (thanks a lot for that)
Even 64x64 and 128x128 aren't displayed properly.

So I've fixed winres as it was registering 256x215 instead of 256x256 in the ICO file, but you can still force a size that Explorer doesn't like, and I should probably talk about that in the Readme.

Thanks a lot.

Thanks for responding so quickly!

I forgot to mention, but in my test branch https://github.com/optix2000/totsugeki/tree/16xicon/winres
I squared all the images and that didn't fix it either. I'll try the latest version and give it a shot.

I'm curious, what changes when you do this?

I think you didn't see the difference because of the icon cache.
Try to rename the exe file with a new name you haven't already used.

As a single string it's one file: an ICO or a PNG. If it's a PNG file instead of an ICO, winres generates the sizes for you (16, 32, 48, 64, 256).
