Examples with EnumMap java.util.EnumMap used on opensource projects

Example 86 with EnumMap

use of java.util.EnumMap in project incubator-weex by apache.

the class OneDReader method doDecode.

/**
 * We're going to examine rows from the middle outward, searching alternately above and below the
 * middle, and farther out each time. rowStep is the number of rows between each successive
 * attempt above and below the middle. So we'd scan row middle, then middle - rowStep, then
 * middle + rowStep, then middle - (2 * rowStep), etc.
 * rowStep is bigger as the image is taller, but is always at least 1. We've somewhat arbitrarily
 * decided that moving up and down by about 1/16 of the image is pretty good; we try more of the
 * image if "trying harder".
 *
 * @param image The image to decode
 * @param hints Any hints that were requested
 * @return The contents of the decoded barcode
 * @throws NotFoundException Any spontaneous errors which occur
