Creating generative art with PHP!
summary
Recreates the open source primitive algorithm in PHP using imagex / imaging and profiles it with Blackfire to find real bottlenecks: repeated export_image_pixels and compare_images calls. Implements a pixel cache, replaces pixel iterators with indexed loops, narrows RMSD to a bounding box and rewrites the difference routine, and iteratively measures gains. Results show dramatic cuts in IO and memory and about a 90% speedup vs the initial PHP run with final timed runs around 22 seconds compared to JavaScript 2m30s.
