How to add image (and how to get the current page)

[baszero]

I didn't find anything related to inserting images in the wiki.

As of PDFBox, inserting an image would work like this:

PDImageXObject pdImage = PDImageXObject.createFromFile("mytest.jpg", pdfDocument.getPDDocument());
PDPageContentStream contents = new PDPageContentStream(pdfDocument.getPDDocument(), pdfDocument.getCurrentPage());

however I don't find any way how to get the current page from pdfbox-layout.

Any advise?

With trial and error I was able to use ImageElement in combination with RenderContext. From the renderContext you can also derive the current page by using the method renderContext.getCurrentPage().

PDDocument pdDocument = new PDDocument();
RenderContext renderContext = new RenderContext(new Document(new PageFormat(), pdDocument));
renderContext.renderElement(renderContext, new ImageElement(inputStream), new VerticalLayoutHint());

However, with this approach I am getting an OutOfMemory in some cases. Here is the relevant stacktrace:
