Hi Maruan, thanks a lot for your comment, this help me really to understand the
way of working about the annotations in PdbBox.
So I've tried to add an appearance COSName.AP to the dictionnary, but I remain
in the same impasse without success at the moment because the annotations are
still not taken into account in the png images generated in the end of the
script.
Hereafter is the initial code refined (without the appearance part since it
doesn't work). If you have an idea how I could add the appearance part in order
to make the annotation appear in the output images, I'd be happy to receive
your suggestions :

> Project: PDFBox
> Issue Type: Bug

> Hi, I'm trying to convert in images (png or jpeg) a PDF file in which I've
> added an annotation within each page through the PDAnnotationTextMarkup
> object.
> I've used PDFImageWriter to achieve this convertion and the images are
> correctly generated excepted that the annotation has disappeared.
> It seems that there is a mistake because if for example I open my PDF file
> with acrobat reader and then I re-save it under a new PDF file and then I
> relaunch my image conversion script with this latter one, the images
> generated will this time contain the annotations.
