byte[] bytes = FileUtils.readFileToByteArray(new File(“E:/Documents/your_logo.gif”));
Picture pic = new Picture(presentation, new ByteArrayInputStream(bytes));
int picId = presentation.getPictures().add(pic);

SEVERE: Servlet.service() for servlet ArcAjaxRequestHandler threw exception
java.lang.NoClassDefFoundError: com/sun/media/jai/codec/ByteArraySeekableStream

at com.manthan.arc.aspose.impl.AbstractAsposePPTExporter.createPresentaion(AbstractAsposePPTExporter.java:157)

the above error takes me to this line
Picture pic = new Picture(presentation, new ByteArrayInputStream(bytes));

why ppt is not getting generated.

Hi Sandeep,

You can use the following code snippet for replacing picture in already created PictureFrame of a template presentation.

private static void replacePictureFunc(Presentation pres) throws Exception
{
try{
InputStream iStream = new BufferedInputStream(new FileInputStream(".\\Template.gif"));

Picture pic = new Picture(pres,iStream);
int picId = pres.getPictures().add(pic);
PictureFrame pf = (PictureFrame)pres.getMainMaster().findShape("Unknown.gif");

pres.getMainMaster().getShapes().addPictureFrame(picId, pf.getX(), pf.getY(), pf.getWidth(), pf.getHeight());
}
catch(Exception e){
e.printStackTrace();
}
}

I hope this info will help you in this regard. If you require any further information, please feel free to contact us.
