Public API and Backwards Incompatible Changes in Aspose.Slides for Java 14.9.0

This page lists all added classes, methods, properties and so on, any new restrictions and other changes introduced with the Aspose.Slides for Java 14.9.0 API.

Public API Changes

Added Methods for Replacing Image to PPImage, IPPImage

New methods added:

• IPPImage.replaceImage(byte[] newImageData)
• IPPImage.replaceImage(IPPImage newImage)

 Presentation presentation = new Presentation("presentation.pptx");

//The first way

byte[] imageData = // ...

presentation.getImages().get_Item(0).replaceImage(imageData);

//The second way

presentation.getImages().get_Item(1).replaceImage(

    presentation.getImages().get_Item(0));

presentation.save("presentation_out.pptx", SaveFormat.Pptx);

Added Methods for Saving Slides Keeping Page Numbers

The following methods have been added:

• void IPresentation.save(string fname, int[] slides, SaveFormat format);
• void IPresentation.save(string fname, int[] slides, SaveFormat format, ISaveOption options);
• void IPresentation.save(Stream stream, int[] slides, SaveFormat format);
• void IPresentation.save(Stream stream, int[] slides, SaveFormat format, ISaveOption options);

These methods allow to save specified presentation slides to PDF, XPS, TIFF, HTML formats. The ‘slides’ array allows to specify page numbers, starting from 1.

 save(string fname, int\[\] slides, SaveFormat format);

 Presentation presentation = new Presentation(presentationFileName);

int[] slides = new int[] { 2, 3, 5 }; //Array of slides positions

presentation.save(outFileName, slides, SaveFormat.Pdf);

Added the SmartArtLayoutType.Custom Enum Value

This type of SmartArt layout represents diagram with custom template. Custom diagrams only can be loaded from presentation file and can’t be created via method ShapeCollection.addSmartArt(x, y, width, height, SmartArtLayoutType.Custom)

Added the SmartArtShape Class and ISmartArtShape Interface

The Aspose.Slides.SmartArt.SmartArtShape class (and its interface Aspose.Slides.SmartArt.ISmartArtShape) add access to individual shapes inside SmartArt diagram. SmartArtShape can be used to change FillFormat, LineFormat, adding Hyperlinks etc.

SmartArtShape does not supported IShape properties RawFrame, Frame, Rotation, X, Y, Width, Height and thrown System.NotSupportedException when attempting to access them.

Example of usage:

 Presentation pres = new Presentation();

ISmartArt smart = pres.getSlides().get_Item(0).getShapes().addSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicBlockList);

ISmartArtNode node = smart.getAllNodes().get_Item(0);

for (ISmartArtShape shape : node.getShapes())

{

    shape.getFillFormat().setFillType(FillType.Solid);

    shape.getFillFormat().getSolidFillColor().setColor(Color.RED);

}

pres.save("out.pptx", SaveFormat.Pptx);

SmartArtShapeCollection class, ISmartArtShapeCollection interface and ISmartArtNode.getShapes() method have been added

The Aspose.Slides.SmartArt.SmartArtShapeCollection class (and its interface Aspose.Slides.SmartArt.ISmartArtShapeCollection) add access to individual shapes inside SmartArt diagram. Collection contains shapes associated with SmartArtNode. Property SmartArtNode.Shapes returns collections of all shapes associated with the node.

Depending of SmartArtLayoutType one SmartArtShape can be shared between several nodes.



 Presentation pres = new Presentation();

ISmartArt smart = pres.getSlides().get_Item(0).getShapes().addSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicBlockList);

ISmartArtNode node = smart.getAllNodes().get_Item(0);

for (ISmartArtShape shape : node.getShapes())

{

    shape.getFillFormat().setFillType(FillType.Solid);

    shape.getFillFormat().getSolidFillColor().setColor(Color.RED);

}

pres.save("out.pptx", SaveFormat.Pptx);
