Aspose.Slides for .NET 24.4 Release Notes

Public API Changes

Introducing a new Modern API

To gradually move away from using System.Drawing dependencies in the public API, starting with version 24.4 we are starting the transition to the new Modern API.

This means that all public API members that have the following classes in their signature will be removed in version 24.8:

• Graphics
• Image
• Bitmap
• PrinterSettings

For more details, see: Modern API

Added new classes and enums:

• IImage - Represents the raster or vector image.
• ImageFormat - Represents the file format of the image.
• Images - the static class that contains methods to instantiate IImage.

Methods/properties to be removed and their replacement in Modern API

The following methods and properties are decared as obsolete and will be removed in version 24.8.

Save Presentation in PowerPoint XML Presentation format - SaveFormat.Xml enum member added

Added the new feature to save a presentation in XML format - using the new enum member SaveFormat.Xml.

Example:

using (Presentation pres = new Presentation())
{
    pres.Save("pres.xml", SaveFormat.Xml);
}

PdfOptions.RasterizeUnsupportedFontStyles property added

Added a new property PdfOptions.RasterizeUnsupportedFontStyles which indicates whether text should be rasterized as a bitmap and saved to PDF when the font does not support bold styling. This approach can enhance the quality of text in the resulting PDF for certain fonts.

Example:

using (Presentation pres = new Presentation())
{
    pres.Save("pres.pdf", SaveFormat.Pdf, new PdfOptions
    {
        RasterizeUnsupportedFontStyles = true
    });
}

PptxOptions.Zip64Mode property added - ZIP64 format support

A new property PptxOptions.Zip64Mode specifies whether the ZIP64 format is used for the Presentation document.

Example:

using (Presentation pres = new Presentation("demo.pptx"))
{
    pres.Save("demo-zip64.pptx", SaveFormat.Pptx, new PptxOptions()
    {
        Zip64Mode = Zip64Mode.Always
    });
}

ZoomObject.Image property replaced with ZoomObject.ZoomImage

Instead of ZoomObject.Image, use the ZoomObject.ZoomImage property:

using (Presentation pres = new Presentation("pres.pptx"))
{
    IZoomFrame zoomFrame = pres.Slides[0].Shapes.AddZoomFrame(150, 20, 50, 50, pres.Slides[1]);
    IPPImage image = pres.Images.AddImage(Images.FromFile("image.png"));
    zoomFrame.ZoomImage = image;
}
