Flipper Icon?

[GitCat3]

So I notice that there seems to be no way to create an icon for the .fap in the flipper zero, is this planned or is there a way to do this and i'm just dumb?

This isn't currently supported by the manifest! macro, but support can definitely be added (see #21).

I think the only real "trick" is converting an image to the format expected by the Flipper Zero. The two options would be:

• Have the user pre-build the icon and just include it in the binary (what we do in the images example)
• Use build.rs or a proc macro to process the image when creating the manifest

I'm probably learning towards the later, since it would make a better experience for developers.

Thanks for the info! Quick question, is any of the code in the sample that you linked actually required to set the file as the icon or can I just include it?

[dcoles]

I think icons used for an external application have the same format as the larger ones in that example. However I believe the icon data needs to be stored in the manifest struct rather than just being a pointer to some other data in the binary.

I am pretty new to rust, I see a thing in the manifest file that you linked that says hasIcon and the icon itself, so do I do something with the manifest in my project to make it include that?

Up until today, it wasn't actually possible to set those fields using the manifest! macro.

This is now fixed in 0.4.1 (see updated answer).

As of flipperzero-rt-0.4.1 it's now possible to set a custom icon for your application! 🥳

From examples/hello-rust:

// Define the FAP Manifest for this application
manifest!(
    name = "Hello, Rust!",
    has_icon = true,
    // See `docs/icons.md` for icon format
    icon = "rustacean-10x10.icon"
);

Icons can be created from any 10x10 px monochrome image. However they need to be converted to the Flipper Zero's custom icon format before they can be used.

Wow thanks!
