Data Matrix Rectangular Extension

DMRE barcode in PHP: the 18 rectangular symbol sizes, encoding schemes, code examples and SVG output

- Nicola Asuni

Standard Datamatrix offers six rectangular sizes. The rectangular extension adds a further set, from 8 by 48 up to 26 by 64, for marking surfaces that are long and thin: cables, pins, the edge of a circuit board. Leave the size parameter empty and the library picks the smallest that fits.
