Public API Changes

Added New Properties: IAudioFrame.FadeInDuration, IAudioFrame.FadeOutDuration, and IAudioFrame.VolumeValue

The new properties, FadeInDuration and FadeOutDuration, have been added to the IAudioFrame interface and the AudioFrame class. These properties allow you to specify the duration of the fade-in and fade-out effects for the media.

The following code sample demonstrates how to add a new audio frame with embedded audio and configure its fade-in and fade-out durations:

var pres = new aspose.slides.Presentation();

// Add Audio Frame
var fileBytes = fs.readFileSync("sampleaudio.mp3");
var audio = pres.getAudios().addAudio(java.newArray("byte", Array.from(fileBytes)));
var audioFrame = pres.getSlides().get_Item(0).getShapes().addAudioFrameEmbedded(50, 50, 100, 100, audio);

// Set the duration of the starting fade for 200ms
audioFrame.setFadeInDuration(200);
// Set the duration of the ending fade for 500ms
audioFrame.setFadeOutDuration(500);

pres.save("AudioFrameFade_out.pptx", aspose.slides.SaveFormat.Pptx);

pres.dispose();

The new property, VolumeValue, has also been added to the IAudioFrame interface and the AudioFrame class. This property allows you to adjust the audio volume as a percentage.

This code sample demonstrates how to add a new audio frame with embedded audio and set its volume to 85%:

var pres = new aspose.slides.Presentation();

// Add Audio Frame
var fileBytes = fs.readFileSync("sampleaudio.mp3");
var audio = pres.getAudios().addAudio(java.newArray("byte", Array.from(fileBytes)));
var audioFrame = pres.getSlides().get_Item(0).getShapes().addAudioFrameEmbedded(50, 50, 100, 100, audio);

// Set the audio volume for 85%
audioFrame.setVolumeValue(85);

pres.save("AudioFrameValue_out.pptx", aspose.slides.SaveFormat.Pptx);

pres.dispose();

Added New Properties: IAudioFrame.TrimFromStart and IAudioFrame.TrimFromEnd

The new properties, TrimFromStart and TrimFromEnd, have been added to the IAudioFrame interface and the AudioFrame class. These properties allow you to specify the duration to trim from the start and end of the media during playback.

The following code sample demonstrates how to add a new audio frame with embedded audio and set the trimming times:

var pres = new aspose.slides.Presentation();

// Add Audio Frame
var fileBytes = fs.readFileSync("sampleaudio.mp3");
var audio = pres.getAudios().addAudio(java.newArray("byte", Array.from(fileBytes)));
var audioFrame = pres.getSlides().get_Item(0).getShapes().addAudioFrameEmbedded(50, 50, 100, 100, audio);

// Set the start trimming time 1.5 seconds
audioFrame.setTrimFromStart(1500);

// Set the end trimming time 2 seconds
audioFrame.setTrimFromEnd(2000);

pres.save("AudioFrameValue_out.pptx", aspose.slides.SaveFormat.Pptx);

pres.dispose();

Added New Properties: IRenderingOptions.DisableFontLigatures, ISVGOptions.DisableFontLigatures, and IHtmlOptions.DisableFontLigatures

The new property, DisableFontLigatures, has been added to the IRenderingOptions, ISVGOptions, and IHtmlOptions interfaces, as well as their implementation classes. This property allows you to control text rendering during export by enabling or disabling ligatures in the rendered text.

The following code sample demonstrates how to use the DisableFontLigatures property to disable ligatures during export.

var pres = new aspose.slides.Presentation("example.pptx");

// Configure export options
var options = new aspose.slides.HtmlOptions();
options.setDisableFontLigatures(true); // Disable ligatures in rendered text

// Export presentation to HTML with disabled ligatures
pres.save("output.html", aspose.slides.SaveFormat.Html, options);

pres.dispose();

Added New Properties: ITextFrame.ParentShape and ITextFrame.ParentCell

The new properties, ParentShape and ParentCell, have been added to the ITextFrame interface and the TextFrame class.

The ParentShape property returns the parent shape or null if the parent object does not implement the IShape interface.
The ParentCell property returns the parent cell or null if the parent object does not implement the ICell interface.

The following examples demonstrate how these properties work:

var presentation = new aspose.slides.Presentation("SomePresentation.pptx");

var autoShape = presentation.getSlides().get_Item(0).getShapes().get_Item(0);
var table = presentation.getSlides().get_Item(0).getShapes().get_Item(1);

// These assertions are always true
assert.deepStrictEqual(autoShape.getTextFrame().getParentShape(), autoShape);
assert.ok((table.get_Item(0,0).getTextFrame()).getParentShape() === null);

presentation.dispose();

var presentation = new aspose.slides.Presentation("SomePresentation.pptx");

var autoShape = presentation.getSlides().get_Item(0).getShapes().get_Item(0);
var table = presentation.getSlides().get_Item(0).getShapes().get_Item(1);

// These assertions are always true
assert.deepStrictEqual((table.get_Item(0,0).getTextFrame()).getParentCell(), table.get_Item(0,0));
assert.ok(autoShape.getTextFrame().getParentCell() === null);

presentation.dispose();
