FingerImageRecord.toBuffer Method¶

Definition¶

Exports the FingerImageRecord to a buffer.

Important

For ANSI/NIST-ITL 1-2011 (AN2K) transaction export, all images will be exported in WSQ in type 14 records, NIEM-XML encoding mode is not supported.

Uint8List toBuffer(FingerImageRecordFormat format, FingerImageCompressionAlgorithm compressionAlgorithm, double compressionLevel)

Parameters

format FingerImageRecordFormat
in Finger image record format to export the finger image object to.

compressionAlgorithm FingerImageCompressionAlgorithm
in Compression algorithm used to compress the images in a record. Note: this value is not prioritary versus the value in an image object, but if the image does not have a compression algorithm, then the one passed here is used.

compressionLevel double
in Compression level. Range and default value depends on the compression algorithm, see CompressionAlgorithm enumeration for more details.

Returns

Uint8List

Buffer to export the finger image object to.

Exceptions

FingerException

An error has occurred during Finger Library execution.
