## 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 |
