{#- หนังสือรับรองการหักภาษี ณ ที่จ่าย (Sec. 50 bis certificate) for a Purchase Invoice.

    The Revenue Department's fillable form (approve_wh3_081156.pdf, A4 = 595 x 842 pt) is the page
    background; every value sits in the rectangle of the corresponding AcroForm field, given here as
    the PDF's (x0, y0, x1, y1) with the origin at the bottom-left so the numbers can be checked against
    the form. Two identical copies are printed: copy 1 goes with the payee's tax return, copy 2 is the
    payee's record. -#}
