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 :

text

PDAnnotationTextMarkup(PDAnnotationTextMarkup.SUB_TYPE_HIGHLIGHT);
txtMark.setColour(colourBlue);
txtMark.setConstantOpacity((float) 0.5); //
Make the highlight 50% transparent

position.setLowerLeftX(lowerLeftX);

}
finally

if (doc != null)
{
