Technical Specification: SVG feDisplacementMap Glitch Art Generator

Overview

A browser-based utility that allows users to manipulate image aesthetics using the native SVG feDisplacementMap filter primitive. This tool focuses on real-time rendering, allowing designers and digital artists to generate glitch-style distortions without requiring professional photo editing software.

Core Features

• Image Upload: Drag-and-drop or file selector to import local images.
• Real-Time SVG Filter Control:
  • Scale: Slider to control the intensity of the displacement.
  • Channel Selection: Dropdowns to choose R, G, B, or Alpha channels for displacement.
  • Preset Filters: Quick-access buttons for common glitch patterns (e.g., "Heavy Static," "Horizontal Drift," "Vertical Slice").
• Canvas Export: Button to render the currently filtered view to a downloadable PNG file.
• In-Memory History: Basic undo/redo functionality using a simple array stack (no persistent storage).
• Responsive Design: Fluid layout that adapts from mobile screens to desktop monitors.

UI/UX Layout

• Header: A clean, minimalist header displaying the tool name and a brief instructional "How-to" trigger.
• Main Tool Area:
  • Left Sidebar: Contains all filter controls, parameter sliders, and configuration inputs.
  • Right Viewport: A central, large preview window displaying the processed image. The background is a subtle, light-gray checkerboard pattern to indicate transparency.
• Interaction Design:
  • Smooth transition animations (e.g., transition: all 0.3s ease) when sliders are adjusted.
  • Minimalist button styles with soft shadows for a modern "SaaS" aesthetic.
  • Clear feedback loops for actions like "Image Uploaded" or "Download Started."

Color Palette

• Backgrounds: #FFFFFF (Pure White) for the main body, #F9FAFB for control panels.
• Accents: #3B82F6 (Vibrant Blue) for primary buttons and active states.
• Typography: #1F2937 (Dark Gray) for headings, #6B7280 (Medium Gray) for labels.
• Border/Dividers: #E5E7EB (Light Gray) for structural separation.

Technical Implementation Constraints

• Architecture: Must be a single HTML file. All CSS (Tailwind CSS via CDN) and JS must be embedded.
• No Storage: Strictly NO use of localStorage, sessionStorage, or cookies. Maintain all state within JavaScript objects/variables.
• Performance: Use requestAnimationFrame for slider updates to prevent UI stuttering.
• Responsiveness: Use CSS Grid or Flexbox to stack the Sidebar and Viewport on small screens (width < 768px).
• Accessibility: Ensure all inputs have proper labels. Use ARIA attributes for dynamic content updates.
• Library Usage: Allowed to use Tailwind CSS (CDN) for styling and standard icon libraries (e.g., Lucide or FontAwesome) for UI elements.
