Banners, codes & pixels components

All components

AsciiFont

Large “figlet-style” block-letter banners from an embedded 5-row font (A–Z, 0–9, punctuation; case-insensitive). Themed accent by default, overridable. API

use tuika::{AsciiFont, view};
view! { node(AsciiFont::new("TUIKA")) }

QrCode

A QR code drawn with half-block cells. The bundled encoder is byte-mode, versions 1–4 (up to 78 bytes at ECC Low — URLs, Wi-Fi credentials, tokens), with Reed-Solomon, interleaving, and masking; larger payloads can be encoded elsewhere and handed to QrCode::from_matrix. API

use tuika::{QrCode, QrEcc, view};
let qr = QrCode::encode("https://everruns.com", QrEcc::Medium).expect("fits v1–4");
view! { node(qr) }

FrameBuffer + FrameBufferView

A mutable RGBA pixel canvas — set/blend/fill_rect/blit, a per-pixel shade shader post-pass, and Sprite spritesheet frames. FrameBufferView packs two vertical pixels per cell with a half-block, so it renders in any terminal; to_image_data() hands the same pixels to the Kitty/iTerm2/Sixel graphics protocols for a crisp render. API

use tuika::{FrameBuffer, FrameBufferView, view};
let mut fb = FrameBuffer::new(64, 32);
fb.clear([20, 20, 40, 255]);
fb.fill_rect(8, 8, 16, 16, [240, 90, 90, 255]);
view! { node(FrameBufferView::new(&fb, 64, 16)) }

KeyHints

Priority-aware footer hints fit only complete key/action pairs. Contextual bindings with higher keymap layer priority survive first as width contracts.

KeymapHelp

A complete, vertically scrollable help view generated from the same active, labeled keymap declarations used for dispatch and footer hints.
