Aspose.SVG for Python via .NET 25.1 Release Notes

Major Features

We are pleased to announce the January release of Aspose.SVG for Python via .NET 25.1.0. This update brings important enhancements aimed at improving how you save and process SVG files in Python. Notable additions include support for compressed SVGZ output, new overloads for the SVGDocument.save(...) method, and a new property in IUserAgentService that improves control over placeholder images. Below is a summary of the key changes:

Enhancements and Fixes

• SVGZ Support and New save(...) Overloads

  • Added the SVGZ member to the SVGSaveFormat enum, allowing you to save documents in the compressed SVGZ format.
  • Enhanced SVGDocument.save(...) methods to automatically compress to .svgz when the file extension is .svgz. For example:
    • save("output.svgz")
    • save("output.svgz", SVGSaveFormat.SVGZ, save_options)

• User Agent Service Updates

  • Introduced the show_image_placeholders property in IUserAgentService. When enabled, fallback (placeholder) images are displayed if an external resource is in an unsupported format.

Updated Public API

1. New Field in SVGSaveFormat

   • SVGSaveFormat.SVGZ: Enables saving SVG documents in compressed SVGZ format.

2. Enhanced SVGDocument.save(...) Overloads

   • Methods now detect the .svgz extension automatically:
     • save(url)
     • save(path)
   • Additional overloaded methods accepting SVGSaveOptions and/or SVGSaveFormat parameters:
     • save(path, save_format, save_options)
     • save(resource_handler, save_format, save_options)
     • save(url, save_format, save_options)

3. show_image_placeholders in IUserAgentService

   • A new boolean property that controls whether placeholder images should be displayed when encountering an unsupported image resource.

These updates make it easier to manage SVG resources—particularly for saving, compressing, and handling fallback images. To learn more or see examples of using the new methods, please refer to our official documentation. If you have any questions, feel free to reach out on our support forums.
