portable splashImage not working

• Version: 22.9.1

• Electron Version: 10.1.5

• Target: portable

I’m using

"portable": {
    "splashImage": "build/splash.bmp"
},

but the only thing that happens when launching the app is this little flash, then the app launches normally.

The title of the window says “Setup : Installing” Am I doing something wrong? I even tried https://www.npmjs.com/package/@catdad/to-bmp

Try converting the image to BMP Version 3 (Microsoft Windows 3.x). ImageMagick convert:

$ convert splash-old.bmp BMP3:splash-new.bmp

Just as a little follow up quite some time later: I generated a bmp using imagick and compared it to the one I had, the difference was that the tool I used set the resolution to 0, imagick sets a default of 72dpi.

So yeah, a bitmap with 24bit and nonzero resolution is needed, we might need to add this to the documentation
