# Optimize PDF file size
|
||||
result = await optimize_pdf(
|
||||
pdf_path="large-document.pdf",
|
||||
optimization_level="balanced", # "light", "balanced", "aggressive"
|
||||

|
||||
|
||||
## ⚡ Performance & Architecture
|
||||
|
||||
### Multi-Library Intelligence
|
||||
Rather than relying on a single approach, we use intelligent fallback systems:
|
||||
- **Text Extraction**: PyMuPDF → pdfplumber → pypdf (automatic selection)
|
||||
- **Table Extraction**: Camelot → pdfplumber → Tabula (tries until success)
|
||||
- **Smart Detection**: Automatically detects scanned PDFs and suggests OCR
|
||||
|
||||
### Async-First Design
|
||||
All operations are built with modern async/await patterns:
|
||||
```python
|
||||
# All tools are fully async
|
||||
results = await asyncio.gather(
|
||||
extract_text("doc1.pdf"),
|
||||
analyze_layout("doc2.pdf"),
|
||||
extract_tables("doc3.pdf")
|
||||
)
|
||||
```
|
||||
|
||||
## Available Tools
|
||||
### Resource Management
|
||||
- **Memory Efficient**: Streaming processing for large documents
|
||||
- **Smart Caching**: Intelligent URL caching and resource cleanup
|
||||
- **Performance Monitoring**: All operations include timing metrics

### OCR Not Working
|
||||
## 🔍 Troubleshooting
|
||||
|
||||
1. **Tesseract not installed**: Make sure Tesseract is installed on your system
|
||||
2. **Language data missing**: Install additional language packs:

||||

||||
```bash
|
||||
# Ubuntu/Debian
|
||||
# Install language packs

|
||||
### Table Extraction Issues
|
||||
|
||||
1. **Java not found**: Tabula requires Java. Install Java 8 or higher.
|
||||
2. **Camelot dependencies**: Install system dependencies:
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo apt-get install python3-tk ghostscript
|
||||
# Install Java (required for Tabula)
|
||||
sudo apt-get install default-jre-headless
|
||||
|
||||
# macOS
|
||||
brew install ghostscript tcl-tk
|
||||
# Install Ghostscript (required for Camelot)
|
||||
sudo apt-get install ghostscript
|
||||
```
|
||||
|
||||
### Memory Issues with Large PDFs
|
||||
- Process specific page ranges: `pages="1,2,3"`
|
||||
- Use streaming capabilities: `method="pdfplumber"`
|
||||
- Consider splitting large documents first
|
||||
|
||||
For very large PDFs, consider:
|
||||
1. Processing specific page ranges instead of the entire document
|
||||
2. Increasing available memory for Python
|
||||
3. Using the streaming capabilities of pdfplumber for text extraction

## Architecture
|
||||
### Intelligent Method Selection
|
||||
```python
|
||||
# Automatic fallback system
|
||||
async def extract_text_with_fallback(pdf_path: str):
|
||||
try:
|
||||
return await extract_with_pymupdf(pdf_path) # Fast, good for most PDFs
|
||||
except Exception:
|
||||
try:
|
||||
return await extract_with_pdfplumber(pdf_path) # Layout-aware
|
||||
except Exception:
|
||||
return await extract_with_pypdf(pdf_path) # Maximum compatibility
|
||||
```
|
||||
|
||||
The server uses intelligent fallback mechanisms:
|
||||
### User Experience Design
|
||||
```python
|
||||
# Before: Confusing zero-based indexing
|
||||
pages=[0, 1, 2] # First 3 pages - not intuitive!
|
||||
|
||||
1. **Text Extraction**: Automatically detects if a PDF is scanned and suggests OCR
|
||||
2. **Table Extraction**: Tries multiple methods (Camelot → pdfplumber → Tabula) until tables are found
|
||||
3. **Error Handling**: Graceful degradation with informative error messages
|
||||
# After: Natural 1-based indexing
|
||||
pages=[1, 2, 3] # First 3 pages - makes perfect sense!
|
||||
|
||||
## Performance Tips
|
||||
# Internal conversion happens automatically
|
||||
def parse_pages_parameter(pages):
|
||||
# Convert 1-based user input to 0-based internal representation
|
||||
return [max(0, p - 1) for p in user_pages]
|
||||
```
|
||||
|
||||
- For large PDFs, process in chunks using page ranges
|
||||
- Use `method="pymupdf"` for fastest text extraction
|
||||
- For complex tables, start with `method="camelot"`
|
||||
- Enable preprocessing for better OCR results on poor quality scans
