Crops each PDF page to a fixed 6×4 inch box with a 1.24″ left offset and 1″ top offset (72 pt/in),
then applies a 90° clockwise page rotation. Output files are named yy-mm-dd.pdf with counters.
Note: This assumes the PDF’s coordinate space matches the MediaBox as typical shipping labels do. If an input PDF has a non-zero
built-in page rotation or unusual boxes, the crop may not match expectations.
