rubberstamp annotation with base 64 image

I'd advise against converting an image that isn't a photograph to jpeg,
this will have artefacts. Use LosslessFactory instead.

Sorry, i would like to confirm, that worked. just dont set a width and
height to the transcoder object. just ensure the base64 svg has a width and
height attribute inside.

Thanks. i found this

PDImageXObject requires a bitmap image. Internally it holds a
java.awt.image.BufferedImage. You will need to convert your SVG to a
BufferedImage. I've not done this, but code on there is code on
Stackoverflow for it using Apache Batik:

Hi Peter
PDImageXObject imageSig = LosslessFactory.createFromImage(pdfDocument,
ImageIO.read(new
ByteArrayInputStream(DatatypeConverter.parseBase64Binary(base64Png))));
works if base64 string is png..
but it does not work if the base 64 is an svg.
data:image/svg+xml;base64,PHN2ZyB4bW......
is this a limitation?
please advise

I think you can create a PDImageXObject object from a BufferedImage using
org.apache.pdfbox.pdmodel.graphics.image.JPEGFactory factory
JPEGFactory.createFromImage( PDDocument, BufferedImage , float quality,
int resolution);
