Public API Changes
Zoom support has been added
The main article on Zoom: Manage Zoom
When you create a Zoom transition in PowerPoint, you can jump to (and from) specific slides, sections, and portions of your presentation in any order you prefer when presenting:
In Aspose.Slides, to provide the same functionality, we added a new enum ZoomImageType, a new interface IZoomFrame, and some new additional methods in IShapeCollection.
ZoomImageType Enum
The ZoomImageType determines whether the Zoom object uses the slide preview or a cover image.
This is the ZoomImageType enum definition:
public final class ZoomImageType
{
private ZoomImageType(){}
/**
* Use the image of the slide or section.
*/
public static final int Preview = 1;
/**
* Use a custom image.
*/
public static final int Cover = 2;
}
IZoomFrame Interface
The IZoomFrame interface with the ZoomFrame implementation class has been added:
public interface IZoomFrame
{
/**
* Gets or sets the image type of a zoom object.
* Read/write {@link ZoomImageType}.
* Default value: Preview
*/
public int getImageType();
public void setImageType(int value);
/**
* Gets or sets the navigation behavior in slideshow.
* Read/write {@code boolean}.
* Default value: false
*/
public boolean getReturnToParent();
public void setReturnToParent(boolean value);
/**
* Gets or sets the slide object that the Slide Zoom object links to.
* Read/write {@link ISlide}.
*/
public ISlide getTargetSlide();
public void setTargetSlide(ISlide value);
/**
* Gets or sets value that specifies whether the Zoom will use the background of the destination slide.
* Read/write {@code boolean}.
* Default value: true
*/
public boolean getShowBackground();
public void setShowBackground(boolean value);
/**
* Gets or sets image for zoom object.
* Read/write {@link IPPImage}.
*/
public IPPImage getImage();
public void setImage(IPPImage value);
/**
* Gets or sets the duration of the transition between Zoom and slide.
* Read/write {@code float}.
* Default value: 1.0f
*/
public float getTransitionDuration();
public void setTransitionDuration(float value);
}
New methods in IShapeCollection interface have been added
These new methods create ZoomFrame objects:
/**
* Adds a new Zoom object to the end of a collection.
*/
public IZoomFrame addZoomFrame(float x, float y, float width, float height, ISlide slide);
/**
* Adds a new Zoom object to the end of a collection.
*/
public IZoomFrame addZoomFrame(float x, float y, float width, float height, ISlide slide, IPPImage image);
/**
* Creates a new Zoom object and inserts it to a collection at the specified index.
*/
public IZoomFrame insertZoomFrame(int index, float x, float y, float width, float height, ISlide slide);
/**
* Creates a new Zoom object and inserts it to a collection at the specified index.
*/
public IZoomFrame insertZoomFrame(int index, float x, float y, float width, float height, ISlide slide, IPPImage image);
Example:
This example shows you how to create a ZoomFrame object with a custom image and specified image frame:
Presentation pres = new Presentation();
try {
//Add a new slide to the presentation
ISlide slide = pres.getSlides().addEmptySlide(pres.getSlides().get_Item(0).getLayoutSlide());
// Create a new image for zoom object
byte[] imageBytes = Files.readAllBytes(Paths.get("image.png"));
IPPImage image = pres.getImages().addImage(imageBytes);
// Add ZoomFrame object
IZoomFrame zoomFrame = pres.getSlides().get_Item(0).getShapes().addZoomFrame(20, 20, 300, 200, slide, image);
// Set zoom frame format
zoomFrame.getLineFormat().setWidth(5);
zoomFrame.getLineFormat().getFillFormat().setFillType(FillType.Solid);
zoomFrame.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.MAGENTA);
zoomFrame.getLineFormat().setDashStyle(LineDashStyle.DashDot);
// Save the presentation
pres.save("presentation.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
if (pres != null) pres.dispose();
}
IHyperlinkManager.setMacroHyperlinkClick method has been added
A new method, setMacroHyperlinkClick, has been added to the IHyperlinkManager interface and HyperlinkManager class.
The setMacroHyperlinkClick method is used to set a macro hyperlink on a click for a shape.
Method declaration:
/**
* Set Macro hyperlink on a click.
*/
public IHyperlink setMacroHyperlinkClick(String macroName);
This code snippet shows you how the setMacroHyperlinkClick method is used to set a macro hyperlink click on a shape:
Presentation pres = new Presentation();
try {
IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.BlankButton, 20, 20, 80, 30);
shape.getHyperlinkManager().setMacroHyperlinkClick("MacroName");
} finally {
if (pres != null) pres.dispose();
}
New methods setRootDirectoryClsid and getRootDirectoryClsid have been added to IPptOptions interface and PptOptions class
New methods, setRootDirectoryClsid and getRootDirectoryClsid, have been added to the IPptOptions interface and PptOptions class.
The setRootDirectoryClsid and getRootDirectoryClsid methods represents the object class GUID (CLSID) that is stored in the root directory entry.
Methods declaration:
/**
* Represents the object class GUID (CLSID) that is stored in the root directory entry. Can be used for COM
* activation of the document's application.
* The default value is '64818D11-4F9B-11CF-86EA-00AA00B929E8' that corresponds to 'Microsoft Powerpoint.Slide.8'.
*/
public java.util.UUID getRootDirectoryClsid();
public void setRootDirectoryClsid(java.util.UUID value);
This code snippet shows you how the custom setRootDirectoryClsid can be set:
Presentation pres = new Presentation();
try {
PptOptions pptOptions = new PptOptions();
// set CLSID to 'Microsoft Powerpoint.Show.8'
pptOptions.setRootDirectoryClsid(UUID.fromString("64818D10-4F9B-11CF-86EA-00AA00B929E8"));
pres.save("pres.ppt", SaveFormat.Ppt, pptOptions);
} finally {
if (pres != null) pres.dispose();
}
