MS Publisher is a document creation program designed for page‑layout‑focused content, supporting files such as MS Publisher 2.0 or later, TXT, RTF, MS Word files, HTML, Unicode text, and more. PUB files may include images, text, graphics and are commonly used for creating flyers, brochures, postcards, and other printed materials. Aspose.PUB for C# .NET is a flexible and easy‑to‑use library developed to work with electronic publication files. This solution supports loading, opening, editing, and conversion of the .pub file format to PDF. It offers quick and reliable conversion of PUB to PDF, HTML, XLSX, DOC, and the most popular image formats. It is suitable not only for integration into your own C# or .NET project but also for building cross‑platform applications that open, merge or convert MS Publisher files without requiring Microsoft Publisher. The API allows users to parse PUB files, read and manipulate layer content, draw text or images on layers, merge layers, detect flattened files, create thumbnails, modify metadata, and export PUB files to a range of formats. Additional imaging filters such as brightness, contrast, gamma adjustments, dithering, blur, Median, Gauss Wiener, Motion Wiener, and Bradley Threshold further expand its capabilities. Continuous API enhancements introduce features such as fill layers, support for various layer resources, vector masks, text layer transformations, and stroke effect rendering.
