About this software

Aspose Diagram is a developer API for creating, reading, editing, and converting Microsoft Visio files. Available for .NET, Java, Python, and Node.js (via Java), it processes Visio formats without requiring Microsoft Visio. The API exposes shapes, connectors, layers, user-defined cells, and document properties, and exports diagrams to PDF, HTML, SVG, images, XAML, and fixed-layout formats. Cloud and SDK options enable server-side or desktop integration.

Frequently asked questions

What can Aspose Diagram be used for in applications?
A diagram-processing library enables programmatic creation, reading, modification, and rendering of diagram files, automating layout adjustments, shape and connector manipulation, and export to image or document formats. Refer to product documentation for supported operations and code examples.
How does integration with existing systems typically work?
Integration is typically via the product API: reference the library in application code, invoke methods to load or modify diagrams, and manage input/output streams for storage, rendering, or transmission. Consult API references and samples for language-specific guidance.
What output options are commonly available for diagrams?
Diagram libraries commonly support rendering to raster and vector images and exporting diagrams for embedding in documents or PDFs. Exact output formats and rendering settings vary; consult product documentation for supported export options.
How are complex diagram elements like shapes and connectors handled programmatically?
APIs expose object models for shapes, connectors, text, and styling, enabling traversal, creation, and modification of diagram elements and attributes. Use these models to update properties, apply transformations, or rebuild layout programmatically.
