Description

IMAQ_SEARCH_MULTIPLE 0 The function searches for multiple 2D barcodes.
IMAQ_SEARCH_SINGLE_CONSERVATIVE 1 The function searches for 2D barcodes using the same searching algorithm as IMAQ_SEARCH_MULTIPLE but stops searching after locating one valid barcode.
IMAQ_SEARCH_SINGLE_AGGRESSIVE 2 The function searches for a single 2D barcode using a method that assumes the barcode occupies a majority of the search region. This method skips some of the predictive portions of the search algorithm used by IMAQ_SEARCH_SINGLE_CONSERVATIVE, which can lead to improved performance. Using this search mode when the barcode does not occupy a majority of the search region, when the barcode is rotated or when the image is blurry, can lead to reduced performance.
IMAQ_BARCODE_2D_SEARCH_MODE_SIZE_GUARD 0xFFFFFFFF Reserved
