decodeMiddle

protected int decodeMiddle(BitArray row,
                           int[] startRange,
                           java.lang.StringBuilder result)
                    throws NotFoundException

从类复制的说明: UPCEANReader

Subclasses override this to decode the portion of a barcode between the start and end guard patterns.

指定者:

decodeMiddle 在类中 UPCEANReader

参数:

row - row of black/white values to search

startRange - start/end offset of start guard pattern

result - StringBuilder to append decoded chars to

返回:

horizontal offset of first pixel after the "middle" that was decoded

抛出:

NotFoundException - if decoding could not complete successfully

decodeEnd

protected int[] decodeEnd(BitArray row,
                          int endStart)
                   throws NotFoundException

抛出:

NotFoundException

checkChecksum

protected boolean checkChecksum(java.lang.String s)
                         throws FormatException

参数:

s - string of digits to check

返回:

UPCEANReader.checkStandardUPCEANChecksum(CharSequence)

抛出:

FormatException - if the string does not contain only digits

convertUPCEtoUPCA

public static java.lang.String convertUPCEtoUPCA(java.lang.String upce)

Expands a UPC-E value back into its full, equivalent UPC-A code value.

参数:

upce - UPC-E code as string of digits

返回:

equivalent UPC-A code as string of digits
