jPDFText is a commercial Java class library developed by Qoppa Software designed to extract text and data content from PDF documents.
Note: Qoppa Software no longer sells new individual licenses for this standalone product, as its core functionalities have been integrated into parent company Apryse’s Java PDF solutions. 📋 Core Functionality
Text Extraction: Extracts the raw textual content of a PDF file, either in its entirety as a single String or page-by-page.
Logical Reading Order: Processes the document’s internal text elements to output strings in their natural reading order rather than their internal layout order.
Word Vectorization: Returns a list of individual words from a PDF as a vector of strings.
Coordinate & Spatial Tracking: Retrieves the explicit rectangular coordinates (X and Y positions) of specific words or complete lines of text.
Metadata Retrieval: Extracts general PDF document information, such as title, author, keywords, creator, and total page count. ⚙️ Technical Architecture
100% Java: Built entirely in Java, ensuring platform independence. It runs seamlessly across Windows, Linux, macOS, and Unix environments.
No Third-Party Dependencies: It relies on Qoppa’s proprietary PDF engine. Developers do not need to install external drivers, runtime environments, or third-party software like Adobe Acrobat or Ghostscript.
Stream & File Handling: Includes constructors to ingest PDFs directly from local files, remote URLs, network drives, or Java input streams (InputStream).
Encrypted File Support: Includes built-in password handlers (IPasswordHandler) to open and process encrypted or password-protected PDF files. 💼 Common Use Cases
Search Engine Indexing: Crawling and parsing unstructured corporate PDFs to build database search indexes.
Structured Data Scraping: Utilizing the coordinate extraction feature to pull target data values (like invoice numbers, balance totals, and dates) from highly structured, templated reports.
Content Archiving: Converting binary PDF files into plain text variants for lightweight digital archiving and auditing. 💻 Code Example: Basic Text Extraction
The entry point of the API is the com.qoppa.pdfText.PDFText class. Below is an architectural overview of how a Java application extracts text page-by-page using Qoppa’s jPDFText API:
import com.qoppa.pdfText.PDFText; public class ExtractText { public static void main(String[] args) { try { // Load the document (filename, password helper if needed) PDFText pdfText = new PDFText(“input.pdf”, null); // Loop through pages using the page count for (int i = 0; i < pdfText.getPageCount(); ++i) { // Extract text for the individual page String pageText = pdfText.getPageText(i); System.out.println(“— Page ” + (i + 1) + “ —”); System.out.println(pageText); } // Clear resources pdfText.close(); } catch (Exception e) { e.printStackTrace(); } } } Use code with caution.
