Creating a .icns file again

John Brownie

I solved this problem in 2012, and then again in 2014, when a change disrupted things. Now Mojave is changing the playing field once more...

The problem:
I need to get the icon for the current keyboard layout and save it in a .icns file, since that's what you have to have.

The old solution:
I get the icon via:
IconRef keyboardIcon = TISGetInputSourceProperty(currentInputSource, kTISPropertyIconRef);

I then get the image representations via:
NSImage *iconImage = [[NSImage alloc] initWithIconRef:keyboardIcon];
NSArray *iconImageReps = [iconImage representations];

The next step is to build a CGImageDestination. The old problem was that CGImageDestinationCreateWithData had a hard limit (undocumented, of course) of 15 images. That limit has apparently now been reduced to 10, only documented by an error message.

Workarounds and the new problem:
My old workaround was to limit it to images smaller than 128x128, which worked. Unfortunately, I now get 36 image representations, and picking 10 doesn't give me enough representations, and I get this message from CGImageDestinationFinalize:
finalize:2477: image destination does not have enough images

The Image I/O documentation says it's no longer being updated, and the last revision date is 2016-09-03. Nothing says that it's deprecated or replaced by something else, as far as I can see.

Am I missing something? Or is there a solution that will actually work?

Thanks for any pointers.

Do you just need to do this once, or is this a reoccurring thing you need to do while your app is running?

Hmm.  I just did this converting PNG images.  I’ll take a look.

There also are online resources that may work to provide you with working samples like this one.  https://iconverticons.com/online/

Did this work in High Sierra?

iconutil -- Utility to convert between '.iconset' and '.icns' files.

Gotta leave it at that for the moment. I’ve got stuff to do. Hope this helps.

OK, that looks hopeful. I'll have to dig a bit further to find out all I need, but this seems to get me in a better direction.

Why no alpha?

Also, just enter man iconutil.

More details.

https://stackoverflow.com/questions/46428673/iconutil-not-working-on-macos-high-sierra?rq=1

Lots here.

https://stackoverflow.com/questions/12306223/how-to-manually-create-icns-files-using-iconutil/40999879#40999879

Old docs:

https://developer.apple.com/library/archive/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Optimizing/Optimizing.html

Use iconutil to Create an icns File Manually

The iconutil command-line tool converts iconset folders to deployment-ready, high-resolution icns files. (You can find complete documentation for this tool by entering man iconutil in Terminal.) Using this tool also compresses the resulting icns file, so there is no need for you to perform additional compression.

It looks like you already have this part

icon_16x16@...
icon_32x32.png
icon_32x32@...

icon_128x128@...
icon_256x256.png
icon_256x256@...
icon_512x512.png
icon_512x512@...

Though it’s an old tip…

Let Xcode Create an icns File Automatically

Xcode 4.4 automatically validates and converts an iconset folder to an icns file. All you need to do is add the iconset folder to your project and build the project. The generated icns file is added automatically to the built product.

Do that and see what it creates. Convert the icns back to a .iconset with iconutil and see what the results are. There might be special naming conventions for dark mode files.

I can't seem to find a way to handle the dark/light versions. Trying iconutil with a system .icns file just gives me the regular ones. So, to make life simpler, I'll just ignore the dark versions and go with the light. It gives my users something to play with while I find a better solution.

Thanks for the help.
