Public API Changes

Convert PowerPoint Presentation to video with animations and transitions

We’ve added a new feature: PowerPoint presentation-to-video conversion. This feature includes:

• animation of transitions between slides
• shape animation
• text animation

Aspose.Slides can now play presentations and generate a set of frames for an entire animation with a specific frame per second (FPS). Those frames can then be used to create a video through tools like FFmpeg.

This PHP code demonstrates a presentation to video export operation with frames set at 30FPS:

$FPS = 30;

$presentation = new Presentation("animated.pptx");

$animationsGenerator = new PresentationAnimationsGenerator($presentation);

$player = new PresentationPlayer($animationsGenerator, $FPS);

$player->setFrameTick(java_values(new Java("com.aspose.slides.phphelper.FrameTickInterfaceImplementation")));

$animationsGenerator->run($presentation->getSlides());

$player->dispose();

$animationsGenerator->dispose();

$presentation->dispose();

The PresentationAnimationsGenerator class is a source that sequentially generates individual animation effects, which are then played back using the PresentationPlayer class. A FrameTick event is generated for each frame to allow you to save the current frame to disk or write the frame to a video stream.

Due to restrictions of PHPJavaBridge, the implementation of the FrameTick interface should be added as another jar file to JavaBridge\WEB-INF\lib directory.

FrameTick interface implementation:

public class FrameTickInterfaceImplementation implements PresentationPlayer.FrameTick {
    @Override
    public void invoke(PresentationPlayer sender, FrameTickEventArgs args) {
        try {
            ImageIO.write(args.getFrame(), "PNG", new File("frame_" + sender.getFrameIndex() + ".png"));
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

MAVEN project: PHPJavaBridgeInterface

PDF 1.7 and PDF 1.6 export support added

We implemented support for PDF export to formats 1.6 and 1.7:

• PdfCompliance.Pdf16
• PdfCompliance.Pdf17

This PHP code demonstrates an export to PDF 1.7 operation:

$presentation = new Presentation("pres.pptx");

$pdfOptions = new PdfOptions();
$pdfOptions->setCompliance(PdfCompliance::Pdf17);

$presentation->save("pres.pdf", SaveFormat::Pdf, $pdfOptions);

$presentation->dispose();

PDF A2a, A2b, A2u, A3a and A3b compliance levels export support added

We implemented support for PDF export operations with A2a, A2b, A2u, A3a and A3b compliance levels:

• PdfCompliance.PdfA2a
• PdfCompliance.PdfA2b
• PdfCompliance.PdfA2u
• PdfCompliance.PdfA3a
• PdfCompliance.PdfA3b

This PHP code demonstrates an operation where a PDF is saved based on the PdfA2a compliance level:

$presentation = new Presentation("pres.pptx");

$pdfOptions = new PdfOptions();
$pdfOptions->setCompliance(PdfCompliance::PdfA2a);

$presentation->save("pres.pdf", SaveFormat::Pdf, $pdfOptions);

$presentation->dispose();

Hyperlink sound management support added

getSound and setSound methods, have been added to the Hyperlink class to represent the played sound of an hyperlink.

$presentation = new Presentation("demo.pptx");

$slide = $presentation->getSlides()->get_Item(0);

// Gets the first shape hyperlink
$hyperlink = $presentation->getSlides()->get_Item(0)->getShapes()->get_Item(0)->getHyperlinkClick();

if (java_values($hyperlink->getSound()) != null)
{
	// Extracts the hyperlink sound in byte array
	$audioData = $hyperlink->getSound()->getBinaryData();
}
	
$presentation->dispose();

OLE object frame relative path to a linked file support added

We implemented a new ability that allows you to access and change the relative file path data for OleObjectFrame using the new getLinkPathRelative method.

$presentation = new Presentation("demo.ppt");

$oleFrame = $presentation->getSlides()->get_Item(0)->getShapes()->get_Item(0);
if (java_values($oleFrame) != null)
{
	echo "The relative path: " . $oleFrame->getLinkPathRelative();
}
	
$presentation->dispose();

StopPreviousSound property added for animation effects

getStopPreviousSound and getStopPreviousSound methods of the Effect class specifies whether the animation effect stops the previous sound.

$presentation = new Presentation("demo.pptx");

// Gets the first effect of the first slide.
$firstSlideEffect = $presentation->getSlides()->get_Item(0)->getTimeline()->getMainSequence()->get_Item(0);

// Gets the first effect of the second slide.
$secondSlideEffect = $presentation->getSlides()->get_Item(1)->getTimeline()->getMainSequence()->get_Item(0);

if (java_values($firstSlideEffect->getSound()) != null)
{
	// Changes the second effect Enhancements/Sound to "Stop Previous Sound"
	$secondSlideEffect->setStopPreviousSound(true);
}
	
$presentation->dispose();

Get base placeholder support added

The Shape.getBasePlaceholder method has been added. It returns a basic placeholder shape (shape from the layout and/or master slide that the current shape is inherited from).

This PHP code shows you how to get all (master/layout/slide) animated effects of a placeholder shape:

$pres = new Presentation("sample.pptx");

$slide = $pres->getSlides()->get_Item(0);
$shape = $slide->getShapes()->get_Item(0);
$shapeEffects = $slide->getLayoutSlide()->getTimeline()->getMainSequence()->getEffectsByShape($shape);

$layoutShape = $shape->getBasePlaceholder();
$layoutShapeEffects = $slide->getLayoutSlide()->getTimeline()->getMainSequence()->getEffectsByShape($layoutShape);

$masterShape = $layoutShape->getBasePlaceholder();
$masterShapeEffects = $slide->getLayoutSlide()->getMasterSlide()->getTimeline()->getMainSequence()->getEffectsByShape($masterShape);
	
$pres->dispose();
