Aspose.TeX for .NET – Rendering Math Examples

These snippets demonstrate rendering LaTeX mathematical formulas to images with Aspose.TeX for .NET. Convert complex mathematical expressions to high-quality PNG or SVG images with flexible configuration options for resolution, colors, and scaling.

Key Use Cases

• Render LaTeX math formulas to PNG
• How to render complex equations to PNG with custom resolution
• Render LaTeX math formulas to SVG
• How to render mathematical expressions to vector graphics
• Render simple inline formulas
• Configure rendering options (resolution, scale, colors)

How to Run Examples

1. Reference Aspose.TeX for .NET: Aspose.TeX on Windows; Aspose.TeX.Drawing on non‑Windows.
2. Copy a snippet into your project.
3. Apply a temporary license as described in the licensing guide.
4. Build and run.
