Line
Create Plain Line
To add a simple plain line to a selected slide of the presentation, please follow the steps below:
- Create an instance of Presentation class.
- Obtain the reference of a slide by using its Index.
- Add an AutoShape of Line type using addAutoShape method exposed by IShapeCollection object.
- Write the modified presentation as a PPTX file.
In the example given below, we have added a line to the first slide of the presentation.
// Instantiate PresentationEx class that represents the PPTX file
Presentation pres = new Presentation();
try {
// Get the first slide
ISlide sld = pres.getSlides().get_Item(0);
// Add an AutoShape of type line
sld.getShapes().addAutoShape(ShapeType.Line, 50, 150, 300, 0);
// Write the PPTX to Disk
pres.save("LineShape.pptx", SaveFormat.Pptx);
} finally {
if (pres != null) pres.dispose();
}
Create Arrow Shaped Line
Aspose.Slides for Java also allows developers to configure some properties of the line to make it look more appealing. Let’s try to configure few properties of a line to make it look like an arrow. Please follow the steps below to do so:
- Create an instance of Presentation class.
- Obtain the reference of a slide by using its Index.
- Add an AutoShape of Line type using addAutoShape method exposed by IShapeCollection object.
- Set the Line Style to one of the styles as offered by Aspose.Slides for Java.
- Set the Width of the line.
- Set the Dash Style of the line to one of the styles offered by Aspose.Slides for Java.
- Set the Arrow Head Style and Length of the start point of the line.
- Set the Arrow Head Style and Length of the end point of the line.
- Write the modified presentation as a PPTX file.
// Instantiate PresentationEx class that represents the PPTX file
Presentation pres = new Presentation();
try {
// Get the first slide
ISlide sld = pres.getSlides().get_Item(0);
// Add an AutoShape of type line
IAutoShape shp = sld.getShapes().addAutoShape(ShapeType.Line, 50, 150, 300, 0);
// Apply some formatting on the line
shp.getLineFormat().setStyle(LineStyle.ThickBetweenThin);
shp.getLineFormat().setWidth(10);
shp.getLineFormat().setDashStyle(LineDashStyle.DashDot);
shp.getLineFormat().setBeginArrowheadLength(LineArrowheadLength.Short);
shp.getLineFormat().setBeginArrowheadStyle(LineArrowheadStyle.Oval);
shp.getLineFormat().setEndArrowheadLength(LineArrowheadLength.Long);
shp.getLineFormat().setEndArrowheadStyle(LineArrowheadStyle.Triangle);
shp.getLineFormat().getFillFormat().setFillType(FillType.Solid);
shp.getLineFormat().getFillFormat().getSolidFillColor().setColor(new Color(PresetColor.Maroon));
// Write the PPTX to Disk
pres.save("LineShape.pptx", SaveFormat.Pptx);
} finally {
if (pres != null) pres.dispose();
