Hi,
The use cases aren't really the same, the cause is. In that scenario we had to update a form field with an image, but when we did that with OpenOffice generated PDFs a gray rectangle (part of the form field's appearance) remained on the page. Looking through the syntax of the PDF, we noticed that OpenOffice put the gray rectangle in the content stream of the page and not in the appearance of the form field. I assume LibreOffice does the same thing. The solution/workaround we used was to request the form field coordinates, remove the form field and overlay the gray rectangle with a white one (the background of the page was white) and then add the image at the correct coordinates. This is a workaround because the rectangle is still there, it's just hidden. You can remove the rectangle from the content stream, but that's not an easy thing to do. I'd advise against using [Open/Libre]Office if possible. You could try the workaround. Kind regards, Michaël.
