PDF Image Extraction

panparsex v0.5.0 introduces comprehensive PDF image extraction capabilities that automatically detect, extract, and associate images with text content.

Basic Image Extraction

from panparsex import parse

# Parse PDF with image extraction enabled
doc = parse("document.pdf", extract_images=True)

# Access extracted images
print(f"Found {len(doc.images)} images")
for img in doc.images:
    print(f"Image {img.image_id} on page {img.page_number}")
    print(f"Dimensions: {img.dimensions}")
    print(f"File: {img.file_path}")
    if img.associated_text:
        print(f"Associated text: {img.associated_text[:100]}...")

Advanced Configuration

# Custom output directory and minimum image size
doc = parse(
    "document.pdf",
    extract_images=True,
    image_output_dir="my_images",
    min_image_size=(100, 100)  # Minimum width and height
)

# Access images by page or section
page_images = doc.get_images_by_page(1)
section_images = doc.get_images_by_section(0)

AI Analysis with Images

from panparsex.ai_processor import AIProcessor

# Parse with image extraction
doc = parse("document.pdf", extract_images=True)

# AI analysis including image context
processor = AIProcessor(api_key="your-openai-key")
result = processor.process_document(
    doc,
    task="Analyze this document including any images and their relationship to text content",
    output_format="structured_json"
)

# Access image analysis results
if 'images_analysis' in result:
    analysis = result['images_analysis']
    print(f"Total images: {analysis['total_images']}")
    print(f"Image contexts: {analysis['image_contexts']}")

CLI Image Extraction

# Extract images from PDF
panparsex parse document.pdf --extract-images

# Specify output directory and minimum size
panparsex parse document.pdf --extract-images --image-output-dir ./images --min-image-size 50 50

# Combine with AI analysis
panparsex parse document.pdf --extract-images --ai-process --ai-task "Analyze images and text content"

Image Metadata

Each extracted image includes comprehensive metadata:

class ImageMetadata:
    image_id: str                    # Unique identifier
    page_number: int                 # Page where image appears
    position: Dict[str, float]       # Position on page (x, y, width, height)
    file_path: Optional[str]         # Path to extracted image file
    file_size: Optional[int]         # File size in bytes
    format: Optional[str]            # Image format (PNG, JPEG, etc.)
    dimensions: Optional[Dict[str, int]]  # Width and height
    extracted_at: datetime           # Extraction timestamp
    associated_text: Optional[str]   # Text near the image
    confidence_score: Optional[float]  # Detection confidence
    meta: Dict[str, Any]             # Additional metadata

Parse with custom options

doc = parse("data.csv", content_type="text/csv") print(doc.meta.extra["csv_data"]["headers"])

    title: Optional[str]
    url: Optional[str]
    path: Optional[str]
    extra: Dict[str, Any]

class Section(BaseModel):

    order: int
    meta: Dict[str, Any]

Advanced Usage

Web Scraping with JavaScript

# Extract JavaScript content from websites
doc = parse("https://spa-website.com", extract_js=True)

# Find JavaScript sections
for section in doc.sections:
    if section.meta.get("type") == "javascript":
        print(f"JS from {section.meta['url']}: {section.chunks[0].text[:200]}...")

Custom Parser Registration

from panparsex import register_parser, ParserProtocol
from panparsex.types import UnifiedDocument, Metadata

class CustomParser(ParserProtocol):
    name = "custom"
    content_types = ("application/custom",)
    extensions = (".custom",)
    
    def can_parse(self, meta: Metadata) -> bool:
        return meta.content_type == "application/custom"
    
    def parse(self, target, meta: Metadata, recursive: bool = False, **kwargs) -> UnifiedDocument:
        # Your parsing logic here
        return UnifiedDocument(meta=meta, sections=[])

# Register the parser
register_parser(CustomParser())

Batch Processing

import os
from pathlib import Path
from panparsex import parse

def process_directory(directory: str):
    """Process all files in a directory."""
    results = []
    
    for file_path in Path(directory).rglob("*"):
        if file_path.is_file():
            try:
                doc = parse(str(file_path))
                results.append({
                    "file": str(file_path),
                    "title": doc.meta.title,
                    "content_length": sum(len(chunk.text) for section in doc.sections for chunk in section.chunks),
                    "sections": len(doc.sections)
                })
            except Exception as e:
                print(f"Error processing {file_path}: {e}")
    
    return results

# Process a directory
results = process_directory("./documents")
for result in results:
    print(f"{result['file']}: {result['sections']} sections, {result['content_length']} chars")
