Aspose.SVG for Python via .NET 25.8 Release Notes

Major Features

Boolean Geometry Operations for SVG Shapes

  • New combine method on SVG geometry elements:
    Perform boolean path operations between any two SVGGeometryElement instances and get the result as a new <path> element (not auto-appended to the DOM).
  • Supported operators via BooleanPathOp:
    UNION, DIFFERENCE, INTERSECTION, EXCLUSION (XOR).
  • Backend requirement:
    Boolean path operations require the SkiaSharp backend. Install the Aspose.SVG.Drawing.SkiaSharp package; otherwise a NotSupportedException will be thrown.

Enhancements and Fixes

  • SVGNET-505:
    Added boolean geometry operations (Union, Difference, Intersection, Exclusion) for all SVGGeometryElement types. The combine method returns a new <path> representing the merged result, enabling advanced shape composition.

  • SVGNET-510:
    Fixed incorrect text positioning caused by miscalculated dx/dy values. The text layout algorithm now renders text consistently and correctly, preventing overlaps or broken visual output.

Public API Changes

Added APIs

  • Enumeration

    • aspose.svg.rendering.BooleanPathOp
      Fields: UNION, DIFFERENCE, INTERSECTION, EXCLUSION.

  • Methods (new combine overload across geometry types)

    • aspose.svg.svggeometryelement.SVGGeometryElement.combine(geometry_element, op)
    • aspose.svg.svgpathelement.SVGPathElement.combine(geometry_element, op)
    • aspose.svg.svgrectelement.SVGRectElement.combine(geometry_element, op)
    • aspose.svg.svgcircleelement.SVGCircleElement.combine(geometry_element, op)
    • aspose.svg.svgellipseelement.SVGEllipseElement.combine(geometry_element, op)
    • aspose.svg.svglineelement.SVGLineElement.combine(geometry_element, op)
    • aspose.svg.svgpolygonelement.SVGPolygonElement.combine(geometry_element, op)
    • aspose.svg.svgpolylineelement.SVGPolylineElement.combine(geometry_element, op)

Method behavior (summary):

  • Returns a new SVGPathElement whose d attribute encodes the boolean result in root <svg> user space (CSS px).
  • Requires both geometries to belong to the same document.
  • Throws ArgumentNullException if geometry_element is None, InvalidOperationException if the element has no owner document, and NotSupportedException when the SkiaSharp backend is unavailable.
