Usage

from alchemark_ai import pdf2md

# Convert PDF to markdown
results = pdf2md("path/to/document.pdf", process_images=True)

# Each result is a FormattedResult object with the structure:
# {
#   "metadata": {
#     "file_path": str,       # Path to the PDF file
#     "page": int,            # Page number
#     "page_count": int,      # Total number of pages
#     "text_length": int,     # Length of the extracted text
#     "processed_timestamp": float  # Processing timestamp
#   },
#   "elements": {
#     "tables": List[Table],  # Tables extracted from the page
#     "images": List[Image],  # Images extracted from the page
#     "titles": List[str],    # Titles/headers detected
#     "lists": List[str],     # List items detected
#     "links": List[Link]     # Links with text and URL
#   },
#   "text": str,              # Markdown text content
#   "tokens": int,            # Number of tokens in the text
#   "language": str           # Detected language
# }

# Access the markdown text of the first page
markdown_text = results[0].text

# Get metadata for the first page
page_number = results[0].metadata.page
total_pages = results[0].metadata.page_count

# Check elements detected in the page
tables_count = len(results[0].elements.tables)
images_count = len(results[0].elements.images)
