Create a “Hello World” Presentation

The following example shows how to create a simple presentation with “Hello World” text.

public class CreateHelloWorldPresentation {
    public static void main(String[] args) throws Exception {
        //Create a Presentation instance
        Presentation ppt = new Presentation();
        //Get the first slide (By default there is 1 slide after creating)
        ISlide slide = ppt.getSlides().get(0);

        Rectangle2D rect = new Rectangle2D.Double(ppt.getSlideSize().getSize().getWidth() / 2 - 150, 80, 300, 150);

        //Append a rectangle shape to the slide
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, rect);
        shape.getShapeStyle().getLineColor().setColor(Color.white);
        shape.getFill().setFillType(FillFormatType.NONE);

        //Append text to the rectangle
        shape.appendTextFrame("Hello World!");

        //Get the 1st paragraph from the text frame
        ParagraphEx paragraph = shape.getTextFrame().getParagraphs().get(0);
        //Set font
        paragraph.getTextRanges().get(0).setLatinFont(new TextFont("Calibri"));
        paragraph.getTextRanges().get(0).setFontHeight(30);
        paragraph.getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
        paragraph.getTextRanges().get(0).getFill().getSolidColor().setColor(Color.black);

        //Save the presentation with file name "HelloWorld.pptx"
        ppt.saveToFile("HelloWorld.pptx", FileFormat.PPTX_2013);
    }
}

Format Text Content in Presentation

The following example shows how to format text content in a presentation.

public class FormatContent {
    public static void main(String[] args) throws Exception {
        //Create a Presentation instance
        Presentation ppt = new Presentation();

        Rectangle2D rect = new Rectangle2D.Double(20, 70, ppt.getSlideSize().getSize().getWidth() - 40, 300);

        //Get the 1st slide
        ISlide slide = ppt.getSlides().get(0);

        //Append shape
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, rect);
        shape.getShapeStyle().getLineColor().setColor(Color.white);
        shape.getFill().setFillType(FillFormatType.NONE);

        shape.getTextFrame().getParagraphs().clear();

        //Append paragraphs and set formatting
        shape.getTextFrame().getParagraphs().append(new ParagraphEx());
        ParagraphEx paragraph = shape.getTextFrame().getParagraphs().get(0);
        paragraph.getTextRanges().append(new PortionEx("This is paragraph 1"));
        paragraph.setAlignment(TextAlignmentType.LEFT);
        paragraph.getTextRanges().get(0).setTextUnderlineType(TextUnderlineType.WAVY);
        paragraph.getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
        paragraph.getTextRanges().get(0).getFill().getSolidColor().setColor(Color.BLUE);

        shape.getTextFrame().getParagraphs().append(new ParagraphEx());
        paragraph = shape.getTextFrame().getParagraphs().get(1);
        paragraph.getTextRanges().append(new PortionEx("This is paragraph 2"));

        for(int i = 0; i < shape.getTextFrame().getParagraphs().getCount(); i++)
        {
           paragraph = shape.getTextFrame().getParagraphs().get(i);
           paragraph.setSpaceAfter(50);
           paragraph.getTextRanges().get(0).setLatinFont(new TextFont("Arial"));
           paragraph.getTextRanges().get(0).setFontHeight(30f);
           paragraph.getTextRanges().get(0).isBold(TriState.TRUE);
        }

        //Create a Presentation instance
        Presentation ppt = new Presentation();

        //Add bubble chart
        Rectangle2D.Double rect1 = new Rectangle2D.Double(90, 100, 550, 320);
        IChart chart = null;
        chart = ppt.getSlides().get(0).getShapes().appendChart(ChartType.BUBBLE, rect1, false);

        //Chart title
        chart.getChartTitle().getTextProperties().setText("Bubble Chart");
        chart.getChartTitle().getTextProperties().isCentered(true);
        chart.getChartTitle().setHeight(30);
        chart.hasTitle(true);

        //Attach the data to chart
        double[] xdata = new double[]{7.7, 8.9, 1.0, 2.4};
        double[] ydata = new double[]{15.2, 5.3, 6.7, 8};
        double[] size = new double[]{1.1, 2.4, 3.7, 4.8};

        chart.getChartData().get(0, 0).setText("X-Value");
        chart.getChartData().get(0, 1).setText("Y-Value");
        chart.getChartData().get(0, 2).setText("Size");

        for (int i = 0; i < xdata.length; ++i) {
            chart.getChartData().get(i + 1, 0).setValue(xdata[i]);
            chart.getChartData().get(i + 1, 1).setValue(ydata[i]);
            chart.getChartData().get(i + 1, 2).setValue(size[i]);
        }

        //Set series label
        chart.getSeries().setSeriesLabel(chart.getChartData().get("B1", "B1"));

        chart.getSeries().get(0).setXValues(chart.getChartData().get("A2", "A5"));
        chart.getSeries().get(0).setYValues(chart.getChartData().get("B2", "B5"));
        chart.getSeries().get(0).getBubbles().add(chart.getChartData().get("C2"));
        chart.getSeries().get(0).getBubbles().add(chart.getChartData().get("C3"));
        chart.getSeries().get(0).getBubbles().add(chart.getChartData().get("C4"));
        chart.getSeries().get(0).getBubbles().add(chart.getChartData().get("C5"));

        //Save the document
        ppt.saveToFile("CreateChart.pptx", FileFormat.PPTX_2013);
        ppt.dispose();
    }
}

Set Document Properties to Presentation

The following example shows how to set document properties, such as author, company, key words, comments, category, title and subject, to a presentation.

public class SetDocumentProperties {
    public static void main(String[] args) throws Exception {
        //Create a Presentation instance
        Presentation ppt = new Presentation();

        //Set the DocumentProperty of PPT document
        ppt.getDocumentProperty().setApplication("Spire.Presentation");
        ppt.getDocumentProperty().setAuthor("E-iceblue");
        ppt.getDocumentProperty().setCompany("E-iceblue Co., Ltd.");
