margin property
Specifies the matrix shape for Data Matrix (type {@link com.google.zxing.datamatrix.encoder.SymbolShapeHint}) Specifies margin, in pixels, to use when generating the barcode. The meaning can vary by format; for example it controls margin before and after the barcode horizontally for most 1D formats. (Type {@link Integer}, or {@link String} representation of the integer value).
