Public API Changes
getNotesStyle method has been added to IMasterNotesSlide interface and MasterNotesSlide class
getNotesStyle() method has been added to IMasterNotesSlide interface and MasterNotesSlide class respectively. Return value specifies the style of a notes text.
Presentation presentation = new Presentation("Presentation.pptx");
try{
IMasterNotesSlide notesMaster = presentation.getMasterNotesSlideManager().getMasterNotesSlide();
if (notesMaster != null) {
// Get MasterNotesSlide text style
ITextStyle notesStyle = notesMaster.getNotesStyle();
//Set symbol bullet for the first level paragraphs
IParagraphFormat paragraphFormat = notesStyle.getLevel(0);
paragraphFormat.getBullet().setType(BulletType.Symbol);
}
presentation.save("Presentation-out.pptx", SaveFormat.Pptx);
}finally {
presentation.dispose();
}
Method com.aspose.slides.IChartData.switchRowColumn() has been added
Swap the data over the axis. Data being charted on the X axis will move to the Y axis and vice versa.
Presentation pres = new Presentation();
try {
IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.ClusteredColumn, 100, 100, 400, 300);
chart.getChartData().switchRowColumn();
pres.save(outputFileName, SaveFormat.Pptx);
}finally {
pres.dispose();
}
Method FontsLoader.getFontFolders() has been added
Returns folders where font files are searched. Those are folders that have been added with loadExternalFonts() method as well as system font folders.
String[] fontFolders = FontsLoader.getFontFolders();
New EmbedFontCharacters enum and addEmbeddedFont() methods have been added
To allow embedding fonts into Presentation the new EmbedFontCharacters enum and two overloaded methods addEmbeddedFont() have been added:
EmbedFontCharacters enum has two members:
- OnlyUsed: Embed only the characters used in the presentation (best for reducing file size).
- All: Embed all characters (best for editing by other people).
New methods addEmbeddedFont() have been added to IFontsManager interface and FontsManager implementation class:
To embed font from existing IFontData:
void addEmbeddedFont(IFontData fontData, EmbedFontCharacters embedFontRule)
To embed font from a binary data:
void addEmbeddedFont(byte[] fontData, EmbedFontCharacters embedFontRule)
Using these methods and choosing the desired embedding rule (represented by EmbedFontCharacters enum), all fonts used in Presentation can be embedded:
IFontData[] allFonts = pres.getFontsManager().getFonts();
IFontData[] embeddedFonts = pres.getFontsManager().getEmbeddedFonts();
for (IFontData font : except(allFonts, embeddedFonts))
{
pres.getFontsManager().addEmbeddedFont(font, EmbedFontCharacters.All);
}
Please note that an ArgumentException will be thrown if embedded font which is already embedded will be added again using addEmbeddedFont() method.
Methods to get-set edges of fill rectangle have been added to com.aspose.slides.IPictureFillFormat interface and PictureFillFormat class
getStretchOffsetLeft, setStretchOffsetLeft, getStretchOffsetTop, setStretchOffsetTop, getStretchOffsetRight, setStretchOffsetRight, getStretchOffsetBottom, setStretchOffsetBottom methods have been added to IPictureFillFormat interface and PictureFillFormat class respectively.
These methods get/set edges of the fill rectangle. When stretching of an image is specified, a source rectangle is scaled to fit the specified fill rectangle.
Each edge of the fill rectangle is defined by a percentage offset from the corresponding edge of the shape’s bounding box. A positive percentage specifies an inset, while a negative percentage specifies an outset.
For example, a left offset of 25% specifies that the left edge of the fill rectangle is located to the right of the bounding box’s left edge by an amount equal to 25% of the bounding box’s width.
Code example:
Presentation presentation = new Presentation();
try {
// Get the first slide of presentation
ISlide slide = presentation.getSlides().get_Item(0);
// Add an AutoShape of Rectangle type
IAutoShape aShape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 300, 300);
// Create image
BufferedImage img = ImageIO.read(new File("image.png"));
IPPImage imgEx = presentation.getImages().addImage(img);
// Set shape's fill type
aShape.getFillFormat().setFillType(FillType.Picture);
// Set shape's picture fill mode
aShape.getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Stretch);
// Set image to fill the shape
aShape.getFillFormat().getPictureFillFormat().getPicture().setImage(imgEx);
// Specify image offsets from the corresponding edge of the shape's bounding box
aShape.getFillFormat().getPictureFillFormat().setStretchOffsetLeft(25f);
aShape.getFillFormat().getPictureFillFormat().setStretchOffsetRight(25f);
aShape.getFillFormat().getPictureFillFormat().setStretchOffsetTop(-20f);
aShape.getFillFormat().getPictureFillFormat().setStretchOffsetBottom(-10f);
// Save created presentation
presentation.save("StretchOffsetExample.pptx", SaveFormat.Pptx);
} finally {
presentation.dispose();
}
