rob thijssen	c8f981f045	feat: phase 5 — Tight decoder with zlib streams and sub-palettes ... codec/tight.rs: - Full Tight (encoding 7) decoder per ByteColorRFBRenderer.a() line 324 - Control byte: bottom 4 bits = zlib stream reset flags, top 4 bits = subencoding (0-15) - Subencoding 8: solid fill (1-byte color) - Subencoding 15: palette-indexed fill (selector + index) - Subencodings 4-7: filtered data with optional 2-color palette - Subencodings 10-13: reduced bit-depth packed (1/2/4 bpp) - Subencodings 0-3: raw 8bpp data - Data >= 12 bytes uses zlib compression with varint length - 4 persistent zlib streams with reset-on-flag logic - All 4 hardcoded sub-palettes ported as RGB332 indices: PALETTE_BW (2), PALETTE_GRAY4 (4), PALETTE_GRAY16 (16), PALETTE_COLOR16 (16 EGA-like colors) - Bit-depth unpackers: 1bpp, 2bpp, 4bpp (MSB-first) - 5 unit tests Updated examples to request [7, 5, 1, 0, -250] (Tight preferred). Tested against real OmniView: correct rendering with Tight encoding. 32 tests passing. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-05-06 14:44:06 +03:00
rob thijssen	e9823aff03	feat: phase 3 — framebuffer, raw decoder, session pump, snapshot ... framebuffer.rs: - Framebuffer struct (8bpp RGB332, row-major) - apply_raw() blit, copy_rect() with overlap-safe logic - to_rgba() via compile-time RGB332 LUT session.rs: - ActiveSession: connect + SetEncodings + initial FBUpdateRequest - Full server message dispatch loop (all 15 message types) - Raw (encoding 0) and CopyRect (encoding 1) decoders - Ping response, bandwidth probe bookends, mode change resize examples/snapshot.rs: - Connects, waits for first FramebufferUpdate, saves PNG - Tested against real OmniView at 10.3.0.130:443 - Successfully captured 640x480 frame Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-05-06 14:23:43 +03:00
