Examples with SymbolInfo com.google.zxing.datamatrix.encoder.SymbolInfo used on opensource projects

Example 1 with SymbolInfo

use of com.google.zxing.datamatrix.encoder.SymbolInfo in project zxing by zxing.

the class DataMatrixWriter method encode.

    if (contents.isEmpty()) {
        throw new IllegalArgumentException("Found empty contents");
    }
    if (format != BarcodeFormat.DATA_MATRIX) {
        throw new IllegalArgumentException("Can only encode DATA_MATRIX, but got " + format);
    }
    if (width < 0 || height < 0) {
        throw new IllegalArgumentException("Requested dimensions are too small: " + width + 'x' + height);
