Method Detail

createBitmap

public static Bitmap createBitmap(ByteMatrix byteMatrix,
                                  int maxBitmapSizeInPixels)

A convience method to encode barcode data represented by the provided byteMatrix. A 4px border will be added surrounding the returned image. This method assumes 0 = white, 1 = black. You would use this method if you encoded your ByteMatrix in the following way:

 QRCode qr = new QRCode();
 Encoder.encode("abcdefg", ErrorCorrectionLevel.L, qr);
 ByteMatrix barcode = qr.getMatrix(); 

 Bitmap bitmap = createBitmap(barcode, 100);
 

Parameters:

matrix - raw data to encode

maxBitmapSizeInPixels - max size of returned bitmap. This value is ignored if it's smaller than the minimum size required to encode the provided ByteMatrix (i.e. byteMatrix.getWidth() * byteMatrix.getHeight()). This value represents a maximum only and is not guarenteed to be equivalent to the returned Bitmap's overall size.

Returns:

A barcode bitmap of the data

Throws:

NullPointerException - if byteMatrix is null.

Since:

BlackBerry API 6.0.0
