Custom Icon Background

Howdy again,

I am trying to create some custom icons but I can't for the life of me figure out how to get a transparent background. I've tried using the magenta color like you can with custom Garmin icons and I've tried a transparent background in Photoshop and saving it as a .bmp or PNG file to no avail. Is this even possible?

    I feel like this post didn't actually go through. Test.

    It got temporarily marked as spam - I don't understand why the decision isn't immediate, but if a message looks questionable, the helpdesk software will delay showing it for a while.

    I wouldn't be surprised if BMP transparency isn't read properly, but a 4-channel PNG with a transparent background should work fine - I've used a number of transparent custom icons in the past.

    When happens when you try to add a transparent icon from CalTopo as a custom icon, e.g.,FF0000 ?

    Your CalTopo Icon works just fine. I think the problem may be my software. When I save it as a 4 channel PNG with Adobe Photoshop...My file size is always somewhere 15-20kb. So when I abandon that and try to use a .bmp with photoshop or a .png with paint is when I fail to get a transparent background. What editing software are you utilizing?

    I was able to use a combination of MS Paint/Power Point to get what I needed. Leaving the link above in case anyone else in the future ever struggles with this like I did.
