Description

method MappingMethod Describes the method for converting 16-bit pixels to 8-bit pixels.
minimumValue int When method is IMAQ_RANGE, minimumValue represents the value that is mapped to 0. When method is IMAQ_PERCENT_RANGE, minimumValue represents the percentage of the range used to compute the pixel value mapped to 0. Otherwise, minimumValue does not affect the mapping policy.
maximumValue int When method is IMAQ_RANGE, maximumValue represents the value that is mapped to 255. When method is IMAQ_PERCENT_RANGE, maximumValue represents the percentage of the range used to compute the pixel value mapped to 255. Otherwise, maximumValue does not affect the mapping policy.
shiftCount int

When method is IMAQ_DOWNSHIFT, shiftCount represents the number of bits the function right-shifts the 16-bit pixel values. Otherwise, shiftCount does not affect the mapping policy.
