If background is not specified, use window.size.

Default locations expected background size to be 540x380.

The x and y coordinates refer to the position of the center of the icon (at 1x scale), and do not take the label into account.

Signing is not required and will lead to unwanted errors in combination with notarization requirements.

While were at it: anyone found a way to define a fixed window position and size for.dmg disk images (quite useful if a background image is there.).

As far as Finder is concerned, a disk image is just another volume.

I have had trouble getting it to stick sometimes, but now that I think about it I may have been trying to edit a read-only image.

I will try again.

I would like to know.

Note: I havent actually done this so it may not work but I have set a picture as the background for other windows, just never on a disk image.

Your background image doesnt have to be hidden, they just do that so theres no clutter on the disk image -- just the application and whatever needs to be seen by the user.
