Constructor Detail

XMLSlideShow

public XMLSlideShow()

XMLSlideShow

public XMLSlideShow(OPCPackage pkg)

XMLSlideShow

public XMLSlideShow(java.io.InputStream is)
             throws java.io.IOException

Throws:

java.io.IOException

Method Detail

onDocumentRead

protected void onDocumentRead()
                       throws java.io.IOException

Description copied from class: POIXMLDocumentPart

Fired when a package part is read

Overrides:

onDocumentRead in class POIXMLDocumentPart

Throws:

java.io.IOException - a subclass may throw an IOException when a document is read

commit

protected void commit()
               throws java.io.IOException

Description copied from class: POIXMLDocumentPart

Save the content in the underlying package part. Default implementation is empty meaning that the package part is left unmodified.

Sub-classes should override and add logic to marshal the "model" into Ooxml4J.

For example, the code saving a generic XML entry may look as follows:

 protected void commit() throws IOException {
   PackagePart part = getPackagePart();
   OutputStream out = part.getOutputStream();
   XmlObject bean = getXmlBean(); //the "model" which holds changes in memory
   bean.save(out, DEFAULT_XML_OPTIONS);
   out.close();
 }
 

Overrides:

commit in class POIXMLDocumentPart

Throws:

java.io.IOException - a subclass may throw an IOException if the changes can't be committed

Description copied from interface: SlideShow

Add an EOT font to the slideshow. An EOT or MTX font is a transformed True-Type (.ttf) or Open-Type (.otf) font. To transform a True-Type font use the sfntly library (see "see also" below)

(Older?) Powerpoint versions handle embedded fonts by converting them to .ttf files and put them into the Windows fonts directory.

When the slideshow is closed, they will be removed.

Specified by:

addFont in interface SlideShow<XSLFShape,XSLFTextParagraph>

Parameters:

fontStream - the EOT font as stream

Returns:

the font info object containing the new font data

Throws:

java.io.IOException - if the fontData can't be saved or if the fontData is no EOT font
