ns resources generate icons: iOS 1024x1024 garbled

[BlueHunter99]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.0.10
• @nativescript/core: 7.0.9
• iOS Runtime: 7.0.1

Describe the bug
ns resources generate icons works perfectly for all of the icons except for the 1024x1024 one. This results in a weird 'garbled' image, which is then used on the app store.

To Reproduce

1. Create new project from sample (in my case Angular + Hello World)
2. Use ns resources generate icons on an icon of your choosing.

Expected behavior
The CLI should generate (scale) the icon properly.

Additional context
I've attached the icon.png which I use while running the command as well as the resulting image.

This just bit me too. I had to pull my app back from review after I discovered this. As a workaround I guess I will just copy my icon over by hand before building but would nice to get this fixed.

I had no idea this command even existed!
Golden standard has been this for long time:

Well, that may be fine for one-offs, but I recreate the icons for development, beta, and production versions so that they show up on my phone differently and I can tell them apart. The dev version is the usual version, when I am deploying a beta test version to TestFlight for example, I recreate the icons for that, and finally when I publish to the store I recreate the production version of the icons. This is all done in my build script which includes this command.

This is caused by line 160 of assets-generation-services.ts but is the fault of the dependency jimp. The rgba(false) function garbles the image.

// This code disables the alpha chanel, as some images for the Apple App Store must not have transparency.
if (assetItem.rgba === false) {
	image = image.rgba(false);    <=== issue here
}

assetItem.rgba is only set to false for 1024 size icon. So, will investigate a fix on jimp, but in the meantime, does anyone know if this line of code is necessary? Why only for the 1024 sized icon?

[crowmagnumb]

Weird that it is only that one though. But OK. :) Anyway, I couldn't figure out the jimp issue on my own so I submitted an issue that you can find here jimp-dev/jimp#954

For anyone that this may help I'm running the following command after ns resources generate icons <src> and that is convert <src> -background white -alpha remove -alpha off AppResources/iOS/Assets.xcassets/AppIcon.appiconset/icon-1024.png where convert is an ImageMagick utility. My icon is 1024, so if yours is not you will have to resize it by adding -resize 1024x1024 to above command.

Oooooh, that did the trick! Nice job! I'l do a pull request since i have the change, though I'ld be stealing your thunder.
