Layout Analysis

Overview

Layout analysis is the process of leveraging Artificial Intelligence (AI) technology to parse and understand the structure of a document's layout. Its primary goal is to extract text, images, tables, layers, and other data from the input documents.

Layout analysis has several common use cases, including:

• Intelligent recognition of tables within PDF documents: This feature is particularly useful for analyzing company financial statements, invoices, bank statements, experimental data, medical test reports, and more.
• Smart extraction of text, images, or tables from PDF documents through layout analysis: This functionality greatly aids in the analysis and extraction of information from identification cards, receipts, licenses, documents, ancient books, and other various types of files.

Features that support Layout Analysis:

• PDF to Word
• PDF to Excel
• PDF to PowerPoint (Slides)
• PDF to HTML
• PDF to RTF
• PDF to TXT
• PDF to CSV
• Extract PDF to JSON
• Extract PDF to Markdown

Notice

• You need to load the DocumentAI model (see Set DocumentAI Model) before using layout analysis.
• When OCR is enabled, layout analysis is automatically enabled.
• AI table recognition is a separate stage controlled by enableAiTableRecognition — see Table Recognition.

Sample

This Sample demonstrates how to use the ComPDF OCR function to convert PDF to DOCX file.

ConverterManager.setAIModel("<model_path>")

val wordOptions = WordOptions()
wordOptions.enableAiLayout = true
val error = ComPDFKitConverter.startPDFToWord("word.pdf", "", "output.docx", wordOptions)
