In This Topic

Description

Error correction level to using in a 2D barcode, ignored if not supported by the barcode type

Property type

Read-write property

Syntax

Visual Basic
Public Property MakeBarcodeErrorCorrectionLevel As Long

Return Type

A long value which represents the error correction level.

Remarks

The default value is -1.

For PDF417 barcodes:

The value range is 0 - 8 and -1.

A value of -1 will cause the component to choose the error correction level based on the size of the PDF417 symbol.

The 9 levels of error correction supported will take up the following amount of space:

0 - 2 code words

1 - 4 code words

2 - 8 code words

3 - 16 code words

4 - 32 code words

5 - 64 code words

6 - 128 code words

7 - 256 code words

8 - 512 code words

For Data Matrix barcodes:

Uses a fixed error correction level.

Auto error correction

Uses error correction levels 2 through 8, which are the recommended according to the PDF417 specification.
The error correction level should be set manually to either level 0 or level 1 for symbols where the MakeBarcodeRows * MakeBarcodeColumns are less than 10. This is due to the fact that the error correction level 2 requires 8 code words.

Note: This property value is ignored if not supported by the barcode type.
