Major Features

We are pleased to announce the November release of Aspose.SVG for .NET 25.10.0!
This version focuses on performance improvements, memory optimization, and better CSS unit support for enhanced compatibility and rendering accuracy across large and complex SVG documents.

Highlights

Feature / ChangeBenefit
Memory Optimization for Large SVGsLower memory footprint when loading and rendering large SVG documents, enabling smoother performance in memory-constrained environments.
Arabic Font Processing OptimizationImproved shaping and layout of Arabic text for faster and more accurate font rendering.
Support for dpcm CSS UnitAllows authors to specify resolutions using dots per centimeter, improving interoperability with CSS standards and print workflows.

Enhancements and Fixes

  • Reduced Memory Usage Enhanced internal DOM and rendering subsystems to lower peak memory consumption when working with large or deeply nested SVG files.

  • Faster Loading of Large Documents Optimized parsing and resource handling routines for faster SVG loading times, especially with multi-layered vector graphics.

  • Improved Arabic Font Rendering Refined text shaping and glyph metrics for Arabic and similar script fonts, resulting in more accurate typographic output.

  • Support for the dpcm CSS Unit Added handling for dpcm (dots per centimeter) in CSS length and resolution calculations to fully align with CSS specifications.
