Created split_png_by_brightness.py to split rasterized logos into separate SVG files by color for Underground Magnetics logo conversion. Key features: - OpenCV contour hierarchy detection for proper hole handling - Letters with enclosed shapes (d, o, g, etc.) now render correctly - Tight brightness thresholds to avoid antialiasing artifacts - Automatic bounding box cropping for optimal file sizes - Black text: brightness < 40 (236k pixels, 21 shape groups) - Grey icon: brightness 108-118 (119k pixels, 2 shape groups) Results: - um_black.svg: 6.1KB, 3070x233px (was 139KB, 3613x391px) - um_grey.svg: 728B, 413x390px (was 253KB, 3613x391px) Files: - split_png_by_brightness.py: Main color separation tool - IMPROVEMENTS.md: Detailed changelog and comparison - README_underground_magnetics.md: Usage documentation - underground-magnetics.eps: Source logo file - um_black.svg: Separated black text (cropped) - um_grey.svg: Separated grey icon (cropped) - requirements.txt: Added opencv-python dependency 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
