# Adobe Photoshop API Implementation Plan
|
|
|
|
This document outlines the implementation plan for fixing the layer ID issue in our Adobe Photoshop API integration.
|
|
|
|
## Problem Statement
|
|
|
|
Our current implementation of the Adobe Photoshop API for text layer updates:
|
|
- Successfully connects to the API
|
|
- Uploads files to Google Cloud Storage
|
|
- Gets valid presigned URLs
|
|
- Receives 202 Accepted responses from the API
|
|
- Processes complete successfully according to status URLs
|
|
- **BUT**: Text layer changes don't appear in the output file
|
|
|
|
The root cause is a mismatch between the layer IDs we use and the internal IDs that Adobe Photoshop API recognizes.
|
|
|
|
## Implementation Plan
|
|
|
|
### Phase 1: ExtendScript Implementation (3 days)
|
|
|
|
1. Create a robust ExtendScript for extracting accurate layer IDs from PSD files
|
|
2. Add functionality to map layer names/paths to internal IDs
|
|
3. Test the script on various PSD files to ensure accuracy
|
|
4. Create a Mac-specific implementation using AppleScript to drive Photoshop
|
|
|
|
#### Deliverables:
|
|
- `extract_internal_ids.jsx`: ExtendScript file
|
|
- `mac_extract_ids.py`: Python wrapper for Mac
|
|
- Documentation for the ID extraction process
|
|
|
|
### Phase 2: JSON Format Update (2 days)
|
|
|
|
1. Modify the JSON generation process to include internal layer IDs
|
|
2. Update the JSON schema to accommodate both user-friendly IDs and internal IDs
|
|
3. Create a conversion utility to update existing JSON files
|
|
4. Update documentation for the JSON format
|
|
|
|
#### Deliverables:
|
|
- Updated JSON schema
|
|
- `update_json_schema.py`: Utility to update existing JSON files
|
|
- Updated documentation
|
|
|
|
### Phase 3: API Integration (3 days)
|
|
|
|
1. Update the Adobe API integration to use internal layer IDs
|
|
2. Implement a fallback mechanism for when internal IDs are not available
|
|
3. Add more robust error handling and validation
|
|
4. Test the integration with various PSD files
|
|
|
|
#### Deliverables:
|
|
- Updated `adobe_ps_api.py` with internal ID support
|
|
- Enhanced error handling and logging
|
|
- Test suite for validation
|
|
|
|
### Phase 4: Workflow Integration (2 days)
|
|
|
|
1. Update the batch processing scripts to use the new approach
|
|
2. Create a unified workflow that works for both local and API processing
|
|
3. Implement a hybrid approach that can fall back to local processing when needed
|
|
4. Update user documentation
|
|
|
|
#### Deliverables:
|
|
- Updated batch processing scripts
|
|
- Unified workflow implementation
|
|
- User documentation
|
|
|
|
## Timeline
|
|
|
|
- **Total Estimated Time**: 10 working days
|
|
- **Priority**: High - This is a critical feature for our workflow
|
|
- **Dependencies**: Access to Adobe Photoshop on Mac for testing
|
|
|
|
## Success Criteria
|
|
|
|
The implementation will be considered successful when:
|
|
|
|
1. Text layer updates consistently work through the API
|
|
2. The workflow is as automated as possible
|
|
3. There is a fallback mechanism for complex files
|
|
4. Documentation is comprehensive and user-friendly
|
|
|
|
## Risks and Mitigations
|
|
|
|
| Risk | Impact | Mitigation |
|
|
|------|--------|------------|
|
|
| Adobe API changes | High | Monitor Adobe documentation for updates |
|
|
| ExtendScript compatibility issues | Medium | Test on multiple Photoshop versions |
|
|
| Complex PSD structures | Medium | Implement fallback to local processing |
|
|
| Performance with large files | Low | Optimize file handling and implement progress reporting |
|
|
|
|
## Long-term Considerations
|
|
|
|
For future versions, consider:
|
|
|
|
1. Caching layer IDs to avoid repeated extraction
|
|
2. Creating a more robust layer mapping system
|
|
3. Implementing direct integration with Adobe Creative Cloud Libraries API
|
|
4. Building a web interface for managing text updates
|
|

## Next Steps
|
|
|
|
1. Approve this implementation plan
|
|
2. Assign resources to each phase
|
|
3. Begin development of ExtendScript implementation
|
|
4. Schedule regular check-ins to monitor progress |
