nUnits

Unit of measure for the rcBarLocation member. Possible values are:

 

Value

Meaning

 

BARCODE_SCANLINES_PER_PIXELS

[0] the rcBarLocation rectangle is measured in pixels.

 

BARCODE_INCHES

[1] the rcBarLocation rectangle is measured in inches. You must multiply the search area by 100 when using the LBarCode::Write function.

 

BARCODE_MILLIMETERS

[2] the rcBarLocation rectangle is measured in mm.

rcBarLocation

The barcode location on the bitmap.

nSizeofBarCodeData

Barcode data size. If it is zero, the string length will be considered as data size.

pszBarCodeData

Pointer to the barcode data string.

 

nIndexDuplicate

Index to the next duplicated barcode. This member will be filled only by LBarCode::Read function. Possible values are:

 

Value

Meaning

 

>=0

Next duplicated index.

 

-1

The barcode is not duplicated.

 

0xFF

The barcode is the last duplicated one.

nTotalCount

Total barcode count found by LBarCode::Read function.

nDupCount

Total count of bar codes duplicated for the current bar code. This member is filled by the LBarCode::Read function.

uFlags

Flags. This member will be filled only by LBarCode::Read function. Possible value is:

 

Value

Meaning

 

BARCODE_MICRO_PDF417_LINKED

MicroPDF417 is linked to a linear symbol printed below it.

uDataCode

MicroPDF417 start code word function for Code128 emulation. This member will be filled by the LBarCode::Read function when reading a MicroPDF417 symbol.

nAngle

Barcode angle in degrees, its value ranges from -18000 to 18000 with two digits precesion. To obtain the real value angle divide it by 100. It is reported when the barcode is read, and it is not used for writing.

Comments

This structure will be filled by LBarCode::Read when reading in barcode information.

You can also fill this structure before calling LBarCode::Write to print the barcode symbol on the bitmap.

There is no limitation on the barcode angle, i.e. all angles can be detected, where the deskew command is limited to +/- 20 degrees. It is very useful to detect document image skew angle to correct the image angle; provide this angle to deskew the image or rotate the image in the reverse direction.

Australian post barcode string has a special format to distinguish different fields (i.e. FCC, DPID, and CIF). The string format puts dashes between fields as follows:  FCC-DIPD-CIF, where FCC is a 2-digit field (valid values are 11, 87, 45, 92, 59, 62, and 44), DPID is an 8-digit field representing the address, and CIF (optional) represents the customer information field. For more information, please refer to the standard. This string format applies for both read/write functions.

GS1 Databar (formerly RSS14) Expanded and Expanded Stacked strings need to be written conforming to a string format that indicates a particular encoding method, such as Method 1, Method 0100, Method 0101. For example, a string (01)00012345678905(10)ABC123 is encoded using Method 1  (i.e. General Identification Data). Note that 14th digit of the item identification number (jn this case, "5"), if it exists, is considered as a check digit and is ignored. A string that is written without following any of these special encoding formats will be encoded by Method 00 (i.e. General Purpose Data).

When read, an extra digit in curly brackets (i.e. { and }) is added to indicate the linkage bit at the beginning of the string. The curly brackets are not part of the encoded barcode data, and they are not defined in the standard. Rather, they distinguish the linkage digit from other data. For example, if a barcode is written with string (01)00012345678905(10)ABC123 while the linkage bit is set to zero, the read function result will be {0}(01)00012345678905(10)ABC123, where {0} is the linkage digit and the remaining characters are the barcode data.

Notes:

  • The BARCODE_1D_UCCEAN_128 type is designed for reading UCCEAN 128 barcode only, and it is not designed for writing this barcode type.

  • Type RSS14 is now GS1 Databar. All references to RSS14 now refer to GS1 Databar.

  • Code Interleaved 2 of 5: I = # of digits and must be even.

  • Linear barcodes are not supported in UNICODE.
