Set Layout Mode in Java Slides

Introduction to Set Layout Mode in Java Slides

In this tutorial, we will learn how to set the layout mode for a chart in Java slides using Aspose.Slides for Java. The layout mode determines the positioning and sizing of the chart within the slide.

Prerequisites

Before we begin, make sure you have the Aspose.Slides for Java library installed and set up in your Java project. You can download the library from here.

Step 1: Create a Presentation

First, we need to create a new presentation.

String dataDir = "Your Document Directory";
Presentation presentation = new Presentation();

Step 2: Add a Slide and Chart

Next, we will add a slide and a chart to it. In this example, we’ll create a clustered column chart.

ISlide slide = presentation.getSlides().get_Item(0);
IChart chart = slide.getShapes().addChart(ChartType.ClusteredColumn, 20, 100, 600, 400);

Step 3: Set Chart Layout

Now, let’s set the layout for the chart. We will adjust the position and size of the chart within the slide using the setX, setY, setWidth, setHeight methods. Additionally, we will set the LayoutTargetType to determine the layout mode.

chart.getPlotArea().setX(0.2f);
chart.getPlotArea().setY(0.2f);
chart.getPlotArea().setWidth(0.7f);
chart.getPlotArea().setHeight(0.7f);
chart.getPlotArea().setLayoutTargetType(LayoutTargetType.Inner);

In this example, we have set the chart to have its layout target type as “Inner,” which means it will be positioned and sized relative to the inner area of the slide.

Step 4: Save the Presentation

Finally, let’s save the presentation with the chart layout settings.

presentation.save(dataDir + "SetLayoutMode_outer.pptx", SaveFormat.Pptx);

Complete Source Code For Set Layout Mode in Java Slides

String dataDir = "Your Document Directory";
Presentation presentation = new Presentation();
try
{
	ISlide slide = presentation.getSlides().get_Item(0);
	IChart chart = slide.getShapes().addChart(ChartType.ClusteredColumn, 20, 100, 600, 400);
	chart.getPlotArea().setX(0.2f);
	chart.getPlotArea().setY(0.2f);
	chart.getPlotArea().setWidth(0.7f);
	chart.getPlotArea().setHeight(0.7f);
	chart.getPlotArea().setLayoutTargetType(LayoutTargetType.Inner);
	presentation.save(dataDir + "SetLayoutMode_outer.pptx", SaveFormat.Pptx);
}
finally
{
	if (presentation != null) presentation.dispose();
}

Conclusion

In this tutorial, we have learned how to set the layout mode for a chart in Java slides using Aspose.Slides for Java. You can customize the chart’s position and size according to your specific requirements by adjusting the values in the setX, setY, setWidth, setHeight, and setLayoutTargetType methods. This gives you control over the placement of charts within your slides.
