Turbo Dither Changelog

Features

• Audio Reactive Dithering: Visualize your music! Upload an audio file to modulate dithering effects in real-time.
• Dynamic Effects: Thresholds and palettes react to your music's frequency data. Kick hits trigger color shuffles and jitter, while treble spikes modulate dither density and brightness.
• Synchronized Recording: Record high-quality (60fps, 8Mbps) video exports perfectly synced with your audio. Supports MP4 and WebM formats.

Performance

• Worker Caching: Implemented a persistent source image cache in the dither worker, significantly reducing data transfer overhead for real-time reactive processing.
• Lookahead Sync: Added a 150ms audio delay buffer to perfectly align heavy visual processing with the audio output.

Features

• Privacy Dashboard: A dedicated Privacy Policy page explaining our local-only processing architecture.
• Data Controls: A "Nuclear Option" to wipe all local application data (cache, settings, preferences) with a single click.
• Cookie Consent: GDPR-compliant cookie banner giving you full control over anonymous analytics.

Improvements

• Camera Privacy: Added explicit privacy notices to the Live Camera mode to reassure users that no video is sent to servers.

Features

• Live Camera Mode: Transform your webcam into a retro masterpiece in real-time! See yourself dithered instantly with support for all algorithms and palettes.
• Video Recording: Record your dithered camera feed directly from the browser. Supports high-quality .webm export with zero-latency hardware-accelerated capture.

Performance

• Architectural Overhaul: Implemented a multi-threaded processing pipeline for the camera. Uses createImageBitmap for zero-latency frame capture and Transferable Objects for zero-copy memory hand-off between threads.
• Algorithm Optimizations: Refactored core dithering loops and color matching logic, resulting in a significant performance boost across the entire app.

Features

• Steganography: Hide secret text messages directly inside your images! Uses LSB (Least Significant Bit) encoding to embed data that survives the dithering process. Decode it by re-uploading the image to Turbo Dither.

Improvements

• Pixel Integrity: Optimized PNG export and upload workflows to ensure bit-perfect data preservation for steganography.

Features

• Pixel sort: Apply pixel sorting effects to your images for unique visual styles based on pixel brightness or HUE.

Performance

• Image Loader Worker: Offloaded image uploading, decoding, and preprocessing to a dedicated web worker. This keeps the UI completely responsive even when loading massive high-resolution images.

Features

• Social Share Card: Show off your work! Generate a beautiful "Before & After" card with your dithered masterpiece, complete with settings details, perfect for sharing on social media.
• Pattern Editor: Take control of the matrix! When using "Ordered (Bayer)" dithering, you can now design your own 8x8 threshold patterns with the new Pattern Editor. Create custom textures, halftone effects, and more.

Features

• Recommended Palette: Automatically generate a custom color palette based on the colors in your image with a single click using the magic wand button.

Bug Fixes

• Zoom/Pan: Fixed issues with image positioning and initial zoom levels to ensure images always fit the viewport correctly on load.
• Paint Mode: Resolved issues with scroll wheel zooming and panning while in paint mode.

Features

• Removed Magnifier: It got replaced by the new Zoom/Pan feature.
• New Control Panel: Redesigned control panel with grouped settings for easier navigation and a cleaner look.
• CRT Effects: Add retro charm with scanlines, vignette, and flicker effects. Toggle it on for that authentic monitor look!
• Glitch Effects: Introduce glitch effects to add digital distortion and visual noise for a unique aesthetic.
• Image Histogram: Visualize the tonal distribution of your image to make precise brightness and contrast adjustments.
• Interactive Tooltips: Learn what each setting does with helpful tooltips on hover.
• Editable Sample: Click the sample image to load it into the editor and experiment immediately.

Improvements

• Collapsible Sections: Organized the Control Panel into collapsible groups (Dithering, Effects, Adjustments) to save space and reduce scrolling.
• UI Polish: Added retro-styled toggle switches and improved layout consistency.

Features

• Custom Color Palette: Create your own palettes! Select "Custom" from the palette list to add, edit, and remove specific colors for your dithered output.

Bug Fixes

• Size calculation: Fixed an issue with size calculation for different file formats.

Bug Fixes

• Navigation: Fixed an issue where clicking on footer or breadcrumbs links would not navigate correctly, often requiring multiple clicks or a page refresh. This was resolved by adjusting the Service Worker caching strategy for Next.js data requests, preventing stale data from causing navigation failures.

Performance

• Optimized Rendering: Memoized key UI components (Control Panel, Sliders, Image Comparison) and stabilized callback handlers to significantly reduce unnecessary re-renders during interaction.
• Faster Processing: Implemented zero-copy data transfer between the main thread and web worker, greatly reducing memory overhead and improving speed when processing large images.

Features

• Gallery Page: Browse a curated collection of dithered art with detailed settings.

Improvements

• Documentation: Updated tips and algorithm descriptions in the About page.

Features

• Intelligent Selection Tool: New Magic Wand tool automatically detects and outlines objects for precise dithering.

Improvements
