User Guide

Basic Workflow (2-Minute Quick Start)

Launch Application: Run ./mvnw javafx:run
Select Filter: Choose from the dropdown (e.g., "Sepia")
Click "Apply Filter": Process the default image
Check Output: See results in output/ directory
Try Different Images: Click sample image buttons to switch

Step-by-Step Image Processing

Choose Image Source:
- Click Landscape for nature scenes
- Click City for urban photography
- Click Portrait for people photos
- Click Original for the default demo image
Select Processing Filter:
- Grayscale - Perfect for classic black & white
- Sepia - Ideal for vintage/nostalgic effects
- Blur - Great for background softening
- Sharpen - Enhance image clarity and details
- Edge Detection - Highlight boundaries and contours
- Emboss - Create 3D relief effects
- Vintage - Apply retro color grading
- Color Boost - Make colors more vibrant
Configure Processing (Optional):
- Asynchronous Processing ✅ (Recommended - keeps UI responsive)
- Tile Size: 20-100px (smaller = more parallel processing)
Apply Filter:
- Click "Apply Filter" button
- Watch real-time progress in the log area
- Processing typically completes in 200-500ms
Review Results:
- Check the processing log for completion status
- Find output files in the output/ directory
- Files are named: filtered_[filter]_[original_name].png

Output Management

All processed images are automatically saved to:

ImageProcessorApp/output/
├── filtered_sepia_quino-al-mBQIfKlvowM-unsplash.jpg.png
├── filtered_grayscale_landscape.jpg.png
├── filtered_edge_detection_city.jpg.png
└── filtered_blur_portrait.jpg.png

Sample Images Included

quino-al-mBQIfKlvowM-unsplash.jpg - Original demo image (loaded by default)
landscape.jpg - Natural landscape photography
city.jpg - Urban cityscape
portrait.jpg - Portrait photography
painting-mountain-lake-with-mountain-background.jpg - Artistic landscape

Performance Tips

Use Async Processing for better UI responsiveness
Smaller tile sizes (20-30px) = more parallelism but higher overhead
Larger tile sizes (60-100px) = less overhead but reduced parallelism
Default tile size (40px) is optimized for most scenarios

Troubleshooting

Application Status Verification

Successful Startup Indicators

When the application runs correctly, you should see:

Starting Advanced Image Processor...
Advanced Image Processor - Starting...
Default image loaded: quino-al-mBQIfKlvowM-unsplash.jpg
Application started successfully!

Successful Processing Output

After applying a filter, the log shows:

All photos done asynchronously!
Total processing time: 277 ms
Image saved at: /path/to/output/filtered_sepia_image.png

Common Issues & Solutions

Application Window Not Appearing

Symptoms: Console shows startup messages but no window appears Solutions:

Check your dock/taskbar for the JavaFX application icon
Try Cmd+Tab (macOS) or Alt+Tab (Windows/Linux) to cycle through windows
Restart the application with: ./mvnw clean compile javafx:run

JavaFX Module Loading Issues

Symptoms: Module javafx.graphics not found errors Solutions:

# Method 1: Clean Maven cache and rebuild
./mvnw clean install

# Method 2: Force JavaFX module download
./mvnw dependency:resolve

# Method 3: Use alternative startup script
chmod +x run.sh && ./run.sh

Processing Hangs or Fails

Symptoms: Filter application doesn't complete or shows errors Solutions:

Restart the application - sometimes JavaFX UI state gets corrupted
Try a different tile size - use 20px for small images, 60px for large ones
Switch to Synchronous processing - uncheck "Asynchronous Processing"
Check available memory - close other applications if needed

Output Files Not Generated

Symptoms: Processing completes but no files in output/ directory Solutions:

Check permissions - ensure write access to the project directory
Verify output directory exists - it should be created automatically
Look in the correct location: ImageProcessorApp/output/
Check the processing log for specific error messages

Performance Optimization

For Faster Processing

Use Asynchronous processing (checked by default)
Set tile size to 60-80px for large images (>2MP)
Close other applications to free up CPU cores
Use SSD storage for input/output operations

For Lower Memory Usage

Set tile size to 20-30px for memory-constrained systems
Process one image at a time
Use Synchronous processing to reduce memory overhead
