Methods

encode(String contents, BarcodeFormat format, int width, int height, [EncodeHint? hints]) → BitMatrix

Encode the contents following specified format. width and height are required size. This method may return bigger size BitMatrix when specified size is too small. The user can set both width and height to zero to get minimum size barcode. If negative value is set to width or height, IllegalArgumentException is thrown.

inherited

encodeContent(String contents, [EncodeHint? hints]) → List<bool>

Encode the contents to bool array expression of one-dimensional barcode. Start code and end code should be included in result, and side margins should not be included.
