AI Image Editor Brush

Purpose & User Intent: AI Image Editor Brush enables AI-assisted brush-based edits on raster images. It solves the need for consistent artistic strokes and efficient retouching, helping designers, illustrators, marketers, and content teams update photos or create stylized assets quickly while preserving overall image fidelity. It supports brush shapes, textures, and opacity controls to emulate traditional media with AI consistency. Core Logic & Features: The tool performs region-aware brush edits using AI-guided stroke synthesis. Required features include image upload, brush preset selection, brush_size, density, and angle, and real-time preview. Optional/advanced features include masking for local edits, layer support, non-destructive history, color-space preservation, and multiple export formats. Inputs & Outputs: Inputs comprise image file, brush preset, brush_size (px), density (0-100), angle (degrees), and optional mask data. Outputs include edited image at original or user-selected resolution in PNG or JPEG; also provides metadata and optional alpha channel preservation. Algorithms & Calculations: The system maps brush_size, density, and angle to stroke geometry; diffusion-based synthesis guides brush strokes with content-aware constraints; blending uses alpha compositing and edge-aware smoothing; color management adheres to sRGB and ICC profiles for export. Error & Edge Cases: If image input is missing, if brush preset is invalid, or if memory limits are reached, operations fail gracefully with domain-specific error codes. Masks with invalid coordinates are ignored or clipped. Large images may be downscaled for preview. Industry/Region & Localization: Uses standard image formats and color spaces (sRGB); exports follow common DPI and resolution conventions; localization supports major languages; no currency data is required. Assumptions & Exclusions: Assumes valid image input and licensed presets; excludes video, RAW import, multi-frame GIF editing, and 3D edits; UI-related constraints and marketing copy are outside scope.
