neoPdf2

Version: 1.0
Category: PDF Editing and Generation
Library: pdf-lib

neoPDF2 is a powerful plugin for VisualNEO Web that enables creation, loading, editing, and rendering of PDF documents directly from your web applications.
Built on top of the robust open-source pdf-lib JavaScript library, it allows you to programmatically manipulate PDF files—whether generating new documents or editing existing ones—entirely within the browser, with no need for external software or online services.

With neoPDF2, you can add and style text, draw shapes, embed images, insert or delete pages, and even apply custom fonts. PDFs can be displayed in an IFrame, opened in a new browser tab, downloaded, or exported as Base64 for server-side storage or transmission.

This plugin is ideal for creating dynamic reports, invoices, certificates, filled-in templates, or any kind of document that needs to be generated or modified from user data in real time.

Key Features

Create new or edit existing PDF files directly in the browser.
Full control over pages, including add, move, insert, copy, and delete.
Add text, links, images, shapes, and vector drawings with RGB colors.
Embed custom fonts (TTF/OTF) and adjust text size, color, and alignment.
Read and modify metadata (title, author, subject, keywords).
Render PDFs in-app (IFrame/embed), in a new tab, or trigger downloads.
Export and import PDFs as Base64 DataURIs for easy integration.
Retrieve document properties and page count for dynamic workflows.

Typical Use Cases

Generating invoices, receipts, or reports directly from form data.
Creating certificates, tickets, or personalized documents.
Building PDF-based editors or document annotation tools.
Automating document assembly workflows within VisualNEO Web apps.
Embedding PDFs dynamically into dashboards or learning tools.
