Photo Outline Tool

Produces an edge-based render of an input image by extracting prominent contours and representing them as solid shapes.
Conceptually, it converts to grayscale, applies an edge-detection filter (Sobel or Canny), thresholds edges, and expands lines to a user-specified thickness. The result is a two-layer composition: a filled center and a contrasting outline.
Intended users include graphic designers, photographers, social media content creators, and production studios. Use cases include posters, thumbnails, decals, and overlays where consistent outlines are required. The tool supports adjustable thickness, color, and fill options, plus export as PNG with transparency or a simple SVG outline for reuse in other workflows.
Core differentiators are precise thickness control, color customization, and compatibility with common raster and vector outputs for rapid integration into creative pipelines.
