Public API Changes

Handout Presentation export layout mode added

A new Handout presentation export layout mode was added. It represents the corresponding PowerPoint “Print as Handouts” feature. An enumeration HandoutType represents the possible handout types:

One slide per page
Two slides per page
Three slides per page
Four slides per page in a horizontal sequence
Four slides per page in a vertical sequence
Six slides per page in a horizontal sequence
Six slides per page in a vertical sequence
Nine slides per page in a horizontal sequence
Nine slides per page in a vertical sequence

Below is an example of rendering of a presentation in the Handout layout:

Presentation pres = new Presentation("pres.pptx");
try {
    RenderingOptions options = new RenderingOptions();
    HandoutLayoutingOptions handoutLayoutingOptions = new HandoutLayoutingOptions();
    handoutLayoutingOptions.setHandout(HandoutType.Handouts4Horizontal);
    handoutLayoutingOptions.setPrintSlideNumbers(false);
    options.setSlidesLayoutOptions(handoutLayoutingOptions);

    FileOutputStream out = new FileOutputStream("pres-handout.png");
    pres.getThumbnails(options, new Size(1024, 1080))[0].compress(android.graphics.Bitmap.CompressFormat.PNG, 100, out);
    out.flush();
    out.close();
} catch(IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

To export presentation in the Handout layout to PDF:

Presentation pres = new Presentation("pres.pptx");
try {
    PdfOptions options = new PdfOptions();
    HandoutLayoutingOptions handoutLayoutingOptions = new HandoutLayoutingOptions();
    handoutLayoutingOptions.setHandout(HandoutType.Handouts4Horizontal);
    options.setSlidesLayoutOptions(handoutLayoutingOptions);

    pres.save("pres.pdf", SaveFormat.Pdf, options);
} finally {
    if (pres != null) pres.dispose();
}

NotesCommentsLayouting is obsolete for RenderingOptions, HtmlOtions, PdfOptions, TiffOptions

NotesCommentsLayouting property declared as obsolete for RenderingOptions, HtmlOtions, PdfOptions, TiffOptions. The property will be removed after the release of version 24.3.

Please use SlidesLayoutOptions property instead:

Presentation pres = new Presentation("pres.pptx");
try {
    PdfOptions options = new PdfOptions();
    NotesCommentsLayoutingOptions notesCommentsLayoutingOptions = new NotesCommentsLayoutingOptions();
    notesCommentsLayoutingOptions.setNotesPosition(NotesPositions.BottomTruncated);
    options.setSlidesLayoutOptions(notesCommentsLayoutingOptions);

    pres.save("pres.pdf", SaveFormat.Pdf, options);
} finally {
    if (pres != null) pres.dispose();
}

InkOptions class have been added

InkOptions and the corresponding IInkOptions interface have been added. It provides options that control the look of Ink objects in exported documents.

InkOptions.HideInk allows to show or hides Ink elements in exported document. InkOptions.InterpretMaskOpAsOpacity can be used to set ROP operation or Opacity for rendering brush. InkOptions.InterpretMaskOpAsOpacity indicates if it Uses ROP operation or Opacity for rendering brush.

Example:

Presentation pres = new Presentation("pres.pptx");
try {
    PdfOptions options = new PdfOptions();
    options.getInkOptions().setHideInk(true);

    pres.save("pres.pdf", SaveFormat.Pdf, options);
} finally {
    if (pres != null) pres.dispose();
}

IPictureFillFormat.DeletePictureCroppedAreas method have been added

IPictureFillFormat.DeletePictureCroppedAreas method allows the cropped areas of the fill Picture:

Presentation presentation = new Presentation("demo.pptx");
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    // Gets the PictureFrame
    IPictureFrame picFrame = (IPictureFrame)slide.getShapes().get_Item(0);

    // Deletes cropped areas of the PictureFrame image
    IPPImage croppedImage = picFrame.getPictureFormat().deletePictureCroppedAreas();

    presentation.save("output.pptx", SaveFormat.Pptx);
} finally {
    if (presentation != null) presentation.dispose();
}

This can help to reduce the size of the presentation.

Shape.IsDecorative property have been added

The new Shape.IsDecorative property allows to set if the shape is “decorative” (used for decorative purposes, for example, some stylistic objects).

Example:

Presentation pres = new Presentation("sample.pptx");
try {
    pres.getSlides().get_Item(0).getShapes().get_Item(0).setDecorative(true);
} finally {
    if (pres != null) pres.dispose();
}
