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 DataMatrix 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.
