Square Raw Mode

Raw two-dimensional barcode rendering in PHP: module grid input, code example and SVG output

- Nicola Asuni

This is a custom format rather than a published symbology, the two-dimensional counterpart of LRAW. It allows a module grid computed elsewhere to be drawn as it is: rows of 0 and 1 separated by commas, one character per module, every row the same length.
