I was trying to use this tool on linux to convert a png to icns file. It seemed to work and produced some file, but I was unable to actually open that file with anything.

Even image magick gives up on this with the folliwing output:

$ magick convert source-file.icns converted-file.png 
convert: no decode delegate for this image format `ICNS' @ error/constitute.c/ReadImage/562.
convert: no images defined `converted-file.png' @ error/convert.c/ConvertImageCommand/3282.

ImageMagick creates a valid icns file from the same source png.

Any chance to have this also released on homebrew?

Hi. Thanks for creating this library. It is very useful for the packaging that we do in https://github.com/fyne-io/fyne.

The recent versions seem to have a ui and depend on gioui for it. This unfortunately means that anyone importing this will get gioui and its dependencies added to their go.sum as well. Given that we are a user interface too, this is something that we would like to avoid. Is moving the ui something that you could consider?

Hey @JackMordaunt

Not sure as I did not dig into this, but v2.2.7 tag works for one cmd but not the other...

# works...
go install github.com/jackmordaunt/icns/v2/cmd/[email protected]

# works...
go install github.com/jackmordaunt/icns/cmd/preview@latest

# fails...
go install github.com/jackmordaunt/icns/cmd/[email protected]

hey @JackMordaunt

i guess this golang toll will replace the one using in gogio at:
https://github.com/gioui/gio-cmd/blob/0a86898b418418e80fba9c12e71dfdf764bb01d6/gogio/macosbuild.go#LL94C23-L94C31

Hi

There is also a problem decoding the TripMode icon: decoding largest image: image: unknown format
Again, opening in Preview is no problem, showing all icon versions as expected.

TripMode.icns.zip

Hi, this is a great project, and I plan to add this to Winget. However, Winget only supports installing from zip archives at the moment. Can you also please release alternative zip binaries in the releases? Thanks!

Hey @andydotxyz

am working on it here: https://github.com/gedw99/gio-sign/

gogio and icns looks like it can work together. will make building cross platform.

The intent is that in CI, we can do a gio build and sign cross any platform to build any platform is the intent.

the rust signer can do this apparently. the signing from anywhere i mean.

first thing though is to get icns working with gogio and then get upstream.
we can integration the preview tool too after that if you want.

Any thoughts on if we can gen a ico file too ?

Windows uses ico files apparently for packaging.

see:
dawenxi-tech/2fa@8ed9d3e

currently this tool work great for apple and icns. Thanks @JackMordaunt

Fyne uses it btw

just a matter of adjusting gogio

Note:
I looked at Fyne packaging but it’s too coupled to Fyne.

Hi

I want to decode the icons of a few apps. Several work well, but some do not. Like the icon of Dropbox which is stored at /Applications/Dropbox.app/Contents/Resources/AppIcon.icns. The files exists and opens in Preview without problems, showing the Dropbox icon in several sizes. However, this library reports the error no icons found?

Hello,

I have a folder ( icon.iconset ) with multiple resized images for different resolution and I want to produce the .icns file.

icnsify -i icon.iconset -o icns
