Context
A Deno-based TypeScript utility is needed to scale images to fixed dimensions. The solution must work in the Deno runtime environment and support common image formats.
Goals / Non-Goals
Goals:
- Scale images to specified fixed dimensions
- Support PNG, JPEG, WebP, and GIF formats
- Preserve aspect ratio with configurable options
- Provide a simple CLI interface
- Run on Deno runtime
Non-Goals:
- Advanced image editing (filters, cropping, rotation)
- Server-side API or web interface
- Real-time image processing pipelines
Decisions
| Decision | Choice | Rationale |
|---|---|---|
| Runtime | Deno | User specified TypeScript with Deno - built-in TypeScript support, modern security model |
| Image library | deno-image or similar Deno-compatible library |
Native Deno support, no Node.js compatibility layer needed |
| CLI approach | Deno args parsing | Simple, no external dependencies for argument handling |
| Aspect ratio | Configurable (stretch or fit) | Flexibility for different use cases |
Risks / Trade-offs
| Risk | Mitigation |
|---|---|
| Limited Deno image processing libraries | Evaluate available options; fallback to WASM-based solutions if needed |
| Performance with large images | Add warnings for very large files; consider streaming for batch operations |
| Format compatibility | Test with common formats; document supported formats clearly |
