This example uses a file.
I wonder if it is possible to add a picture using a BufferedImage created during runtime.
Any informations on this?

You can use instead the method:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

public static BinaryPartAbstractImage createImagePart(
                        OpcPackage opcPackage,
                        Part sourcePart, byte[] bytes) throws Exception
 

Parsed in 0.014 seconds, using GeSHi 1.0.8.4

but note that behind the scenes, it still creates a temp file. This is because org.apache.xmlgraphics.image.loader.ImageManager gets org.apache.xmlgraphics.image.loader.ImageInfo from a URL.

Hmmm... I wonder whether it could be fed a data URI?

Thanks for your answer.
It worked for me. I used a PngEncoder to encode the BufferedImage and then put it in as a byte array.

A temp file creation is ok, because we have access to the filesystem but the images are not saved but need to be generated with real time data for each new presentation. That was the whole problem.

Thanks for your help.
