Need help in aligning Image in PDF header using page.insert_htmlbox() method

[varun-rf]

I'm encountering an issue with page.insert_htmlbox() while trying to add a header with an image to a PDF. Despite attempting to align the image to the center using inline CSS, it consistently aligns to the left side. Interestingly, the text for the tagline aligns properly in the middle of the page.

Here's the HTML snippet I'm using:

<div style="font-family: arial, helvetica, sans-serif; font-size: 13px;">
    <div style="font-family: arial, helvetica,
        sans-serif; font-size: 13px;">
        <div style="font-family: arial, helvetica, sans-serif; font-size: 13px;">
            <div style="font-family: arial, helvetica, sans-serif; font-size: 13px;"><img style="display: block;
                    margin-left: auto; margin-right: auto;"
                    src="<--base64 data-->"
                    alt="\" width="100" height="101">
            </div>
            <div style="font-family: arial, helvetica, sans-serif; font-size: 13px; text-align: center;">
                <strong>tagline</strong>
            </div>
        </div>
    </div>
</div>

In Python, I'm attempting to adjust the page dimensions and insert the HTML:

doc = fitz.open(pdfpath)
h_height = 100 # Just a placeholder height for testing
for page in doc:
  prect = page.rect
  myrect = fitz.Rect(0, 0, prect.width, h_height)
  page.set_mediabox(fitz.Rect(0, 0, prect.width, prect.height + h_height))
  page.insert_htmlbox(myrect, text=header_html)

Despite specifying center alignment for the image, it remains aligned to the left. Any insights on how to resolve this issue would be greatly appreciated!

This works as you seem to intend:

html = """<div style="text-align:center;"><img src="image2.jpg" height=100><br>tagline</div>"""
arch = fitz.Archive(".")
rect = fitz.Rect(100, 100, 500, 400)
doc = fitz.open()
page = doc.new_page()
page.insert_htmlbox(rect, html, archive=arch)
page.draw_rect(rect, color=(1, 0, 0))
doc.ez_save(__file__.replace(".py", ".pdf"))

BTW I am amazed that you were successful using embedded image data. The documentation clearly says, that this is not supported ... only external images are.

If you specify both, height and width for an image: you know that this will negate "keep aspect ratio"?
