Watermark image not created for the last page of a document section

[scottredshaw]

Hi, I am attempting to build some pdf documents with a draft watermark. I have added the draft watermark by adding a semi-transparent image with no background layered over every page so the text can be read from under the image.

The issue I have been having is that it doesn't create the watermark on the last page of each section.

If anyone has any ideas why this might be happening, please let me know?

This is the code that creates the watermark:

class ContentPageTemplate(BodyPageTemplate):

    def __init__(self, *args, **attributes):
        super().__init__(*args, **attributes)`

    def page(self, document_part, page_number, chain, **kwargs):
        return ContentPage(document_part, self, page_number, chain, **kwargs)


class ContentPage(BodyPage):

    def __init__(self, document_part, template, page_number, chain):
        super().__init__(document_part, template, page_number, chain)

        metadata = self.document.metadata
        document_status = metadata[DOCUMENT_STATUS]
        if document_status.lower() == "draft":
            self.watermark_area = DownExpandingContainer("watermark_area", CONTENT, self)
            draft_water = Image(path_to("images/DRAFT_MARK.png"), width=21 * CM, height=29.70 * CM, style="Draft watermark")
            self.watermark_area << draft_water

Hi!

The issue I have been having is that it doesn't create the watermark on the last page of each section.

I can't readily say why this happens, but rinohtype already provides a simpler way to set background images for pages. In your template configuration file, you can set the background property on a page template:

[contents_page]
background = 'contents_background.pdf', scale=fit

If you do want to lose the configurability of the watermark (document_status), try setting the container type to BACKGROUND instead to see whether that solves your issue.

P.S. I see you're using a PNG image for the background. You should use vector images where appropriate to improve print quality (and reduce file size).

Hi, After changing CONTENT to BACKGROUND in DownExpandingContainer my problem has been solved.

Thanks
