Rastermill ships guarded image processing for Node agents
Rastermill is a Node image-processing library built for agent workflows, with in-process Photon support, native codec fallbacks, and explicit pixel-budget guards. It is designed to handle common raster operations safely and predictably, including probe, transparency checks, and encode, while rejecting oversized or ambiguous inputs before they can cause process explosions.
// ANALYSIS
Hot take: this is infrastructure-first image plumbing, not a flashy media SDK, and that is exactly why it matters for agent runtimes.
- –The main value is safety: pixel budgets, bounded outputs, and refusal to process unknown-sized images reduce the blast radius of malicious or malformed inputs.
- –The runtime strategy is pragmatic: use Photon in-process when possible, then fall back to native tools like `sips`, ImageMagick, GraphicsMagick, ffmpeg, or Windows codecs when needed.
- –The API is intentionally small and agent-friendly, centered on `probe`, `transparency`, and `encode` with typed results.
- –This is especially relevant for AI agent systems that ingest user-supplied images and need predictable behavior under load.
