Image extraction

[waterdragon78]

I have no idea what I'm doing, but is it possible to extract images using this tool?

Hey there, good question! This tool is able to work with SilverImagesDB.LE.bin in the form of raw data, but does not (yet) support converting their raw bitmap image format into something usable. This would be a good feature to eventually implement!

Any way to manually convert the raw bitmap data into an image?

I've added some preliminary support for decoding bitmap images across a few recent commits on main! It's been tested on the external images database on a 5th, 6th, and 7th generation Nano.

Grayscale images may be currently messed up in terms of dimensions - would definitely appreciate feedback if you notice anything horribly wrong!

Two things: I have noticed a few images blank (example 229442012.png and 229442112.png), dunno if thats intentional by apple though. Also, creating seems to have broke (or im not doing it right, unsure.) This is what I got:

silverutil create /Users/arbifox/Desktop/test/ ~/Desktop/test.bin
thread 'main' panicked at src/cli/src/main.rs:56:18:
failed to deserialize YAML representation: Error("resources[0]: missing field id", line: 4, column: 3)
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Encoding of bitmap images isn't yet supported! However, that YAML issue is separate - will get that fixed, thank you for taking a look!

Could you let me know what device type/firmware version you're seeing these blank images on?
