This is an interesting request.  There's no way to *convert* a PNG to
PDF.  You can *embed* a bitmap into a PDF, and ReportLab can do that in
a half-dozen lines of code, but it's not "converted" in any way.

    from PIL import Image
    from reportlab.pdfgen import canvas
    from reportlab.lib.pagesizes import LETTER
    from reportlab.lib.utils import ImageReader

    hello = Image.open('/tmp/hello.png')
    ir = ImageReader(hello)

    canv = canvas.Canvas( 'try.pdf', pagesize=LETTER )
    canv.setPageCompression( 0 )
    canv.drawImage( ImageReader(hello), 200, 200 )
    canv.showPage()
    canv.save()
