## 1. Project Setup
|
|
|
|
- [x] 1.1 Initialize Deno project with deno.json configuration
|
|
- [x] 1.2 Set up directory structure (src/, cli.ts)
|
|

## 2. Core Image Scaling Implementation
|
|
|
|
- [x] 2.1 Create image loader module supporting PNG, JPEG, WebP, GIF
|
|
- [x] 2.2 Implement scale function with exact dimensions (stretch) mode
|
|
- [x] 2.3 Implement scale function with fit mode (preserve aspect ratio)
|
|
- [x] 2.4 Implement scale function with cover mode (preserve aspect ratio, crop)
|
|
- [x] 2.5 Create image saver module with format detection
|
|
|
|
## 3. Batch Processing
|
|
|
|
- [x] 3.1 Implement directory scanner for supported image formats
|
|
- [x] 3.2 Create batch processor with progress reporting
|
|

|
|
|
|
## 4. CLI Interface
|
|
|
|
- [x] 4.1 Create CLI argument parser (input, output, width, height, mode)
|
|

|
|
- [x] 4.3 Implement batch scaling command (directory/multiple files)
|
|
- [x] 4.4 Add error messages and exit codes for invalid input
|
|
- [x] 4.5 Add help documentation (--help flag)
|

|
|
## 5. Testing & Validation

|
|
|
- [x] 5.1 Create test images for each supported format
|
|
- [x] 5.2 Write unit tests for scale functions
|
|
- [x] 5.3 Write integration tests for CLI commands
|
|
- [x] 5.4 Test batch processing with mixed formats
|
|
- [x] 5.5 Verify output dimensions match specifications
