Public API Changes

Support for Summary Zoom and Section Zoom

We implemented support for Section zoom and Summary zoom. See the Manage Zoom article.

This Java code demonstrates the creation of SectionZoomFrame and SummaryZoomFrame objects:

Presentation pres = new Presentation();
try {
    //Adds a new slide to the presentation
    ISlide slide = pres.getSlides().addEmptySlide(pres.getSlides().get_Item(0).getLayoutSlide());
    slide.getBackground().getFillFormat().setFillType(FillType.Solid);
    slide.getBackground().getFillFormat().getSolidFillColor().setColor(Color.GRAY);
    slide.getBackground().setType(BackgroundType.OwnBackground);

    // Adds a new section to the presentation
    pres.getSections().addSection("Section 1", slide);

    //Adds a new slide to the presentation
    slide = pres.getSlides().addEmptySlide(pres.getSlides().get_Item(0).getLayoutSlide());
    slide.getBackground().getFillFormat().setFillType(FillType.Solid);
    slide.getBackground().getFillFormat().getSolidFillColor().setColor(Color.CYAN);
    slide.getBackground().setType(BackgroundType.OwnBackground);

    // Adds a new section to the presentation
    pres.getSections().addSection("Section 2", slide);

    //Adds a new slide to the presentation
    slide = pres.getSlides().addEmptySlide(pres.getSlides().get_Item(0).getLayoutSlide());
    slide.getBackground().getFillFormat().setFillType(FillType.Solid);
    slide.getBackground().getFillFormat().getSolidFillColor().setColor(Color.MAGENTA);
    slide.getBackground().setType(BackgroundType.OwnBackground);

    // Adds a new section to the presentation
    pres.getSections().addSection("Section 3", slide);

    //Adds a new slide to the presentation
    slide = pres.getSlides().addEmptySlide(pres.getSlides().get_Item(0).getLayoutSlide());
    slide.getBackground().getFillFormat().setFillType(FillType.Solid);
    slide.getBackground().getFillFormat().getSolidFillColor().setColor(Color.GREEN);
    slide.getBackground().setType(BackgroundType.OwnBackground);

    // Adds a new section to the presentation
    pres.getSections().addSection("Section 4", slide);

    // Adds a SectionZoomFrame object
    ISectionZoomFrame sectionZoomFrame = pres.getSlides().get_Item(0).getShapes().addSectionZoomFrame(20, 20, 300, 200, pres.getSections().get_Item(1));

    // Adds SummaryZoomFrame object
    ISummaryZoomFrame summaryZoomFrame = pres.getSlides().get_Item(0).getShapes().addSummaryZoomFrame(350, 50, 300, 200);

    // Saves the presentation
    pres.save("presentation.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Low Code API

We implemented a low code API that allows you to perform popular operations using only a few lines of code.

For example, with this single line of code, you can convert a PowerPoint to PDF:

Convert.autoByExtension("pres.pptx", "pres.pdf");

This is another example that demonstrates shows you how to output each portion of text in a presentation using as few lines of code as possible:

Presentation pres = new Presentation("pres.pptx");
try {
    ForEach.portion(pres, (portion, para, slide, index) -> System.out.println(portion.getText()));
} finally {
    if (pres != null) pres.dispose();
}

ObjectData, EmbeddedFileExtension, and EmbeddedFileData have been removed from the IOleObjectFrame interface

Obsolete properties ObjectData, EmbeddedFileExtension, and EmbeddedFileData have been removed from IOleObjectFrame interface. Use the setEmbeddedData method and getEmbeddedData methods from the IOleObjectFrame interface instead.
