Public API Changes

Following methods of the INotesSlide interface have been removed:

  • Bitmap GetThumbnail(float scaleX, float scaleY);
  • Bitmap GetThumbnail(Size imageSize);

Use ISlide.GetThumbnail method with parameter of type INotesCommentsLayoutingOptions instead.

Following methods of the ISlide interface have been removed:

  • void RenderToGraphics(bool withNotes, Graphics graphics, int width, int height);
  • void RenderToGraphics(bool withNotes, Graphics graphics, float scale);
  • void RenderToGraphics(bool withNotes, Graphics graphics);

Use RenderToGraphics method with parameter of type INotesCommentsLayoutingOptions instead.

Property bool IncludeComments has been removed from IHtmlOptions, IPdfOptions, ISwfOptions and ITiffOptions interfaces. Use INotesCommentsLayoutingOptions interface instead.

Named constants PdfNotes, TiffNotes, SwfNotes and HtmlNotes have been removed from the SaveFormat enumeration. Use specific options with INotesCommentsLayoutingOptions element for saving presentation instead.

BackgroundEffectiveData class and IBackgroundEffectiveData interface have been added

Aspose.Slides.IBackgroundEffectiveData interface and it’s implementation by Aspose.Slides.BackgroundEffectiveData class have been added. They represent effective background of slide and contain information about effective fill format and effective effect format.

IBaseSlide.CreateBackgroundEffective method has been added

CreateBackgroundEffective method has been added to IBaseSlide interface and BaseSlide class. Using this method allows to get effective values for slide’s background.

Sample code below outputs effective background fill:

Presentation pres = new Presentation("SamplePresentation.pptx");
IBackgroundEffectiveData effBackground = pres.Slides[0].CreateBackgroundEffective();
if (effBackground.FillFormat.FillType == FillType.Solid)
    Console.WriteLine("Fill color: " + effBackground.FillFormat.SolidFillColor);
else
    Console.WriteLine("Fill type: " + effBackground.FillFormat.FillType);

New IProgressCallback interface has been added

New IProgressCallback interface has been added to ISaveOptions interface and SaveOptions abstract class. IProgressCallback interface represents a callback object for saving progress updates in percentage.

public interface IProgressCallback
{
    /// <summary>
    /// Reports a progress update.
    /// </summary>
    /// <param name="progressValue">A value of the updated progress.</param>
    void Reporting(double progressValue);
}

Code snippets below show how to use IProgressCallback interface:

using (Presentation presentation = new Presentation(fileName))
{
    ISaveOptions saveOptions = new PdfOptions();
    saveOptions.ProgressCallback = new ExportProgressHandler();
    presentation.Save(pdfFileName, SaveFormat.Pdf, saveOptions);
}

class ExportProgressHandler : IProgressCallback
{
    public void Reporting(double progressValue)
    {
        // Use progress percentage value here
    }
}

Pot value has been added to LoadFormat and SaveFormat enumerations

The new Pot value has been added to Aspose.Slides.LoadFormat and Aspose.Slides.SaveFormat enumerations. This value represents Microsoft PowerPoint 97-2003 Presentation template format.

Support of management images as BLOBs has been added

The new method has been added to IImageCollection interface and ImageCollection class to support adding large image as streams to treat them as BLOBs:

IPPImage AddImage(Stream stream, LoadingStreamBehavior loadingStreamBehavior);

Adding new image as BLOB to the presentation

This example demonstrates how to include the large BLOB (image) and prevent a high memory consumption.

static void AddingNewBlobImageToPresentation()
{
    // supposed we have the large image file we want to include into the presentation
    const string pathToLargeImage = "largeImage.png";

    // create a new presentation which will contain this image
    using (Presentation pres = new Presentation())
    {
        using (FileStream fileStream = new FileStream(pathToLargeImage, FileMode.Open))
        {
            // let's add the image to the presentation - we choose KeepLocked behavior, because we not
            // have an intent to access the "largeImage.png" file.
            IPPImage img = pres.Images.AddImage(fileStream, LoadingStreamBehavior.KeepLocked);
            pres.Slides[0].Shapes.AddPictureFrame(ShapeType.Rectangle, 0, 0, 300, 200, img);

            // save the presentation. Despite that the output presentation will be
            // large, the memory consumption will be low the whole lifetime of the pres object
            pres.Save("presentationWithLargeImage.pptx", SaveFormat.Pptx);
        }
    }
}
