V26.1 での更新項目

機能

• Improved asynchronous navigation model - Updated NavigateAsync(...) implementations to be declared as async methods internally, ensuring that asynchronous execution starts immediately at the API boundary rather than returning a pre-created Task. This improves thread utilization and behavior in high-concurrency and UI-sensitive environments.
• Rendering Memory Optimization - Reduced memory usage during rendering by optimizing internal data structures and allocation patterns, improving...

Released: Dec 22, 2025

V25.12 での更新項目

機能

• Asynchronous Document Navigation - Added NavigateAsync(...) overloads to Aspose.Svg.Dom.Document, enabling asynchronous navigation from URLs, streams, strings, and request messages, with CancellationToken support.
• JavaScript Stack Update - Migrated the scripting pipeline dependencies to Jint 3.0.2 and Esprima 3.0.4.

Released: Nov 29, 2025

V25.11 での更新項目

機能

• Improved Algorithm for Splitting SVG Images into Pages - Reworked the internal layout and pagination logic to minimize redundant calculations and data copies when dividing SVG content into pages. This leads to noticeably faster exports to multi-page formats.
• Reduced Memory Usage During Pagination - Optimized internal data structures used in the paging pipeline to lower memory pressure, especially for documents with hundreds or thousands of elements spread across multiple pages.

Released: Nov 14, 2025

V25.10 での更新項目

機能

• 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...

Released: Sep 29, 2025

V25.9 での更新項目

機能

• Significantly improved processing and rendering of complex text content and upgraded CSS custom properties (the var() function) for spec-accurate styling.
• SVG Text Decorations - Extended support for text decorations by adding the line-through property to ensure correct strike-through rendering.
• Extended Unicode Coverage - Implemented CMAP format 12 sub-table handling in font processing to render characters beyond the BMP (e.g., many emoji and historic scripts).
• CSS Custom Properties (var...

Released: Aug 21, 2025

V25.8 での更新項目

機能

• Added boolean geometry operations (Union, Difference, Intersection) for all SVGGeometryElement types. The Combine method produces a new <path> element representing the merged result, enabling advanced shape composition.

不具合の修正

• Fixed incorrect text positioning due to miscalculated dx/dy values. The text layout algorithm now renders text consistently and correctly, preventing overlaps or broken visual output.

Released: Jul 24, 2025

V25.7 での更新項目

機能

• Added new SVGZ Save Options - A new type, 'SVGZSaveOptions', is now available to help you control the behavior of SVGZ serialization – providing enhanced flexibility when exporting compressed SVG content.
• Enhanced Document Navigation Methods - Several overloads of the Navigate method have been added to enable loading document content from strings, streams or request messages with built-in cancellation support.
• Convenience Properties for DOM and CSS - Multiple Value properties have been...
