Aspose.Slides for .NET 23.2 Release Notes

Public API Changes

.NET 6 Support

Now has full support for .NET6 - without using dependencies on GDI/libgdiplus (System.Drawing.Common package).

Thus, when used in Azure/AWS or other cloud solutions, it is now preferable to use Aspose Slides for .NET 6, since this dependency is often either missing or limited in capability when used in services like AWS Lambda, Azure Function and others.

Specific Linux case: While CentOS 7 GLIBC version is 2.14, Aspose.Slides for .NET 6 requires Linux x86_x64 with GLIBC 2.23 and higher.

.NET 5 has been replaced by .NET 6 in the Nuget package

For projects that require .NET5 support you can continue to use Aspose.Slides for .NETStandard (which is part of the NuGet package and continues to be supported).

Find and replace text fragments with changes in formatting

We implemented support for finding and replacing text fragments with changes in formatting. A new method in the public API has been added for this purpose: SlideUtil.FindAndReplaceText.

This C# code demonstrates a search for all portions of “[this block] " and then replaces them with “my text” filled in red:

using (Presentation pres = new Presentation("pres.pptx"))
{
    PortionFormat format = new PortionFormat
    {
        FontHeight = 24f,
        FontItalic = NullableBool.True,
        FillFormat =
        {
            FillType = FillType.Solid,
            SolidFillColor =
            {
                Color = Color.Red
            }
        }
    };
    Aspose.Slides.Util.SlideUtil.FindAndReplaceText(pres, true, "[this block] ", "my text", format);
    pres.Save("replaced", SaveFormat.Pptx);
}
