Why does my icon look distorted?

Why does my icon look distorted?
Hi, this is my first post in this forum.

I have a 128x128px image, that I export to a Windows Icon file 32bbp, 8bit, no palette, uncompressed using Gimp.

The icon file, copied to the desktop looks as expected, but when I assign the icon to any shortcut, the icon seems distorted with rough edges and no semi-transparent pixels, see the very left icon in the screenshot.

I'm running Win 8.1

Thank you in advance!

I have tried a layered icon with various sizes going up to 256, but ran into the same issue.

I think the problem may be with the semi-transparent pixels (i.e. pixels with opacity < 100) . But I'm not sure.

I've downloaded another 128px icon (and it's PNG) online and it looks fine when I use it, but when I convert the PNG to an icon, I get similar quality loss, that's why I'm wondering if I might be doing something wrong in GIMP.

Hi Matthysdt,

When you export your image to a .png, can you show a screen shot of the export settings you are using.

I never export to PNG, I create and save the image as a PNG from the start.
Will it help if I export it?

my mistake - I have just re-read your original post. Confused

Thank you for the trouble Kevin

Your icon looks fine, but it has very little detail to distort:

Can you perhaps make an icon of my PNG? (attached)

Thank you paynekj

Sorry for taking so long to respond.

You icon distorts less than my own, even when I convert your xcf to icon it looks better than when I convert my own PNG to icon. Do you have any tricks that may help me obtain better quality?

Is there a reason why you opted for the XCF file format rather than PNG?

Thanks!

For a quick reply (not sure when paynekj will be on again)

My guess for the .XCF attachment is so you can see how the layers are composite(put together)
Plus it retains the original quality. When you export to .png or another format, there are many export options.

Thank you for your inputs Ofnuts.

I never attempted to resize any icons.

All my icons have "layers" for all the different dimensions ranging from 16px to 256px.

The multi-dimensions aspect is not the issue here IMHO.

Thanks iForStyle007

Seems the image format is not to be blamed here.

I created a new icon from scratch by combining the following images in a single a single layer:
16.xcf
32.xcf
64.xcf
128.xcf
256.xcf

I attached the resulting image in xcf format to this post, when I export the image to ICO, it looks terrible.

Yet somehow paynekj did exactly the same and his icon looks way better, so what am I doing wrong?

One difference that I did pick up was that all my layers seem centered, where paynekj's layers all seem top-left-aligned.

Thanks!

You gotta be freakin kidding me!! This actually did the trick, all this time it was because I didn't know to include 48x48. Any other dimensions I should know of?

Thank you Kevin, for taking the time to read my question and responses and help me figure this out!

(Unlike certain whistling wise-asses that shall not be mentioned) :-)
Just kidding, thank you everyone for your insights!

RE: Why does my icon look distorted?
Thanks Ofnuts, it seems from that post that an icon should rather have too many dimension than too little.
Think I'll use 16, 24, 32, 40, 48, 64, 96, 128, 256
