Issue while building App with small Background Images

To reproduce this issue simply change the background image inside home.component.scss into an image thats smaller than 256x256px. Now try to build the project with npm run electron:windows.

This will fail with the following Error Message :
image C:\Users\username\angular-electron\dist\small-image.0488d9eb003af2735cd0.png must be at least 256x256

Is there a way to fix this issue? It seems like a strange behavior between the Output generated by ng and the electron-builder who´s maybe trying to use those as App Icons.

I have found a simpler solution to this error:

• download the latest version of electron-builder v22.1.0

• now run, npm run build:prod

• once that is completed, inside the dist folder copy favicon.256x256.png and paste it in the same folder, repeat this step again to have two copies of the favicon.256x256.png image, then rename both copies to sort_asc.9326ad44ae4bebdedd14.png and sort_asc_disabled.d7dc10c78f23615d3285.png (This name should be same as the two sort_asc_ images in the dist folder)

• Now run, npx electron-builder build --windows

• DONE!! it should build successfully without error

Well, I have found a solution.

Inside electron-builder.json under win and mac and linux change the "icon": "dist" to "icon": "dist/icons" Now build the project with npm run build:prod. Inside the dist folder create a new folder called icons. Now simply cut all the icon files from the dist folder and past them into your dist/icons folder. Now run npx electron-builder build --windows ( or --mac / --linux) and everything works fine.

Hopefully there is a simpler solution to this issue.
