Crate plot_icon

Generates 19-circle identicons in png and in svg format from &[u8] input slice. Slice length could be arbitrary, as identicon generation starts with input hashing. Typical input is a public key.

Identicon example:

The identicon color scheme and elements arrangement follow the published javascript code for polkadot identicon generation. This crate is intended mainly for use by Signer.

Crate also supports generation of identicon-like images with pre-set colors in RGBA format, mainly for test purposes.

Feature "pix" supports generation of png images, feature "vec" - generation of svg images. Both are made available by default.
