Best PDF SDK for Visual Studio

CAD6engine is a comprehensive SDK library for developers that outputs technical and financial data, raster images, text, SVG graphics, and DWG/DXF file content into premium-quality PDF documents. Unlike traditional methods, it avoids using the limited Windows printer interface or GDI, delivering high-resolution PDFs with Unicode text support, layers, transparency effects, and multiple color models such as RGB, CMYK, HSB, gray, and CIELab. The engine supports bi-directional conversion between SVG and DWG/DXF file formats and enables the combination of multiple graphical files into one PDF document with customizable objects and text. CAD6engine offers full control over all output parameters, ensuring precise and customizable results. It can be fully integrated into applications, running quietly in the background or optionally displaying a complete graphical user interface for user interaction. The SDK is compatible with C++ compilers that support its dynamic link library (MKCAD6engine.dll) and library file (MKCAD6engine.lib). Designed for C++ developers with basic Win32/x64 knowledge, it supports various development environments and compiler toolchains. CAD6engine is ideal for applications requiring professional PDF generation from CAD and graphic sources.

Generate and manage PDF files with ease by utilizing features such as splitting, appending, stamping, encrypting, extracting, and filling. PDFKit.NET is a fully managed .NET class library designed for the creation and manipulation of PDF documents, packaged as a single assembly that allows for straightforward xcopy deployment. It operates independently with no additional requirements beyond the .NET framework itself. At the heart of PDFKit.NET lies a coherent and user-friendly object model comprising various classes like document, page collection, page, canvas, shape, bookmark, annotation, and field. The development team's primary goal is to simplify the integration of this class library into larger applications. With PDFKit.NET 5.0, users can fill in text fields, checkboxes, and radio buttons, while also having the option to save the forms in either an editable state or as a flattened PDF. Additionally, this version introduces the ability to handle dynamic XFA documents through the new XFA processor API, enhancing functionality. Furthermore, PDFKit 5.0 enables users to extract all graphics from a page, compiling them into a collection of various shapes, which can include text, images, and curves, providing versatile options for document manipulation. This makes PDFKit.NET an invaluable tool for developers looking to incorporate robust PDF handling capabilities into their applications.
