方法详细资料

encode

public final BitMatrix encode(java.lang.String contents,
                              BarcodeFormat format,
                              int width,
                              int height)
                       throws WriterException1

从接口复制的说明: Writer

Encode a barcode using the default settings.

指定者:

encode 在接口中 Writer

参数:

contents - The contents to encode in the barcode

format - The barcode format to generate

width - The preferred width in pixels

height - The preferred height in pixels

返回:

BitMatrix representing encoded barcode image

抛出:

WriterException1 - if contents cannot be encoded legally in a format

encode

public BitMatrix encode(java.lang.String contents,
                        BarcodeFormat format,
                        int width,
                        int height,
                        java.util.Map<EncodeHintType,?> hints)
                 throws WriterException1

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.

指定者:

encode 在接口中 Writer

参数:

contents - The contents to encode in the barcode

format - The barcode format to generate

width - The preferred width in pixels

height - The preferred height in pixels

hints - Additional parameters to supply to the encoder

返回:

BitMatrix representing encoded barcode image

抛出:

WriterException1 - if contents cannot be encoded legally in a format

getDefaultMargin

public int getDefaultMargin()

encode

public abstract boolean[] encode(java.lang.String contents)

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

参数:

contents - barcode contents to encode

返回:

a boolean[] of horizontal pixels (false = white, true = black)
