Aspose.SVG for Python via .NET 25.10 Release Notes

This page contains release-note information for Aspose.SVG for Python via .NET 25.10.0 (November 2025).

Major Features

We are pleased to announce the November release of Aspose.SVG for Python via .NET 25.10.0.
This version focuses on memory optimization, faster loading of large SVG documents, and improved CSS unit support, including a new resolution unit for dots per pixel.

Highlights

Feature / Change	Benefit
Memory optimization for large SVGs	Lower memory footprint when loading and rendering complex SVG content in Python applications.
Faster loading of large documents	Reduced load times for big or deeply nested SVG files.
Arabic font processing optimization	More accurate and efficient rendering of Arabic and similar complex-script fonts.
Support for `dpcm` CSS unit and CSS_X	Better alignment with CSS standards and more precise control over resolution handling.

Enhancements and Fixes

Reduced memory usage
Internal DOM and rendering subsystems were optimized to lower peak memory consumption when working with large or complex SVG documents, which is especially useful for server-side Python workloads.
Faster loading of large documents
Parsing and resource handling routines were improved to speed up loading of multi-layered or deeply nested SVG graphics.
Improved Arabic font rendering
Text shaping and glyph metrics processing for Arabic and similar scripts were refined to produce more accurate typographic output.
Support for the dpcm CSS unit
Added support for the dpcm (dots per centimeter) CSS unit in length and resolution calculations, improving compatibility with print-oriented workflows and CSS specifications.

Public API Changes

Added APIs

Module / Class	Member	Description
`aspose.svg.dom.css.CSSPrimitiveValue`	`CSS_X`	New constant representing a CSS primitive value for dots per pixel (x) resolution units.

The new CSS_X constant is available on the CSSPrimitiveValue class in the aspose.svg.dom.css module.

from aspose.svg.dom.css import CSSPrimitiveValue

# Example: using the CSS_X unit constant
unit_type = CSSPrimitiveValue.CSS_X
