Explore the Advanced Features of our PDF API
Quick Start
This quick tutorial walks you through creating a simple "Hello, World!" app that uses GcPdf to generate and save a PDF file.
Document Properties
Make viewing faster with linearized PDFs. Documents properties include metadata, compression, and font embedding behavior. Restrict printing, copying, and PDF editing.
Print PDF Documents to Printer
Print PDF document directly to a printer on Windows platform.
Fonts
Create, initialize, and use the Font Collection class to manage and use when rendering texts.
Page Headers
Print page headers and footers in PDF documents. Organize pages by headings to help users get a sense of the page’s organization and structure.
Merge Pages
Combine and organize multiple documents into one PDF–making it simple to share and send render pages of one PDF to another.
Attachments
Attach photos, text, drawings, PDFs, and other file types (including AcroForm) to a PDF. If you move the PDF to a new location, the attachments move with it.
Text
Review the basics of rendering text in GcPDF (DrawString and DrawTextLayout), character formatting, paginated text, text trimming, word, character wraps, and much more.
Images
Generate pages of slides from all images in a directory and extract images from PDF documents.
PDF Report Templates
Automate and customize documents and report generation. PDF Templates allow you to bind HTML templates to various data sources by using report templates that generate PDF files from HTML.
Document Properties
Make viewing faster with linearized PDFs. Documents properties include metadata, compression, and font embedding behavior. Restrict printing, copying, and PDF editing.
Annotations
Create, edit, or delete annotations from existing PDF documents. Several annotations are supported from PDF specifications.
Advanced Text
Design magazine style, multi-column page layouts with balanced columns and outlines. Multi-language text is supported, including RTL, east-Asian languages, and vertical text.

Digital Signatures
Digitally sign PDFs, inspect signature properties, or remove existing signatures. Add Image signatures to PDF Documents.
Security
Encrypt or decrypt PDF Documents. When a document is encrypted, its contents become unreadable. An authorized user can decrypt the document to obtain access to the contents. If a PDF document is password encrypted, the user must enter the password in order to view the document.
