puUpperAvr

Pointer to an array containing the new average pixel value for those pixels with values between the average pixel value for the entire bitmap and the highest pixel value in the bitmap. The size of the array equals either one if uFlags is YUV_SPACE or GRAY_SPACE or three if uFlags is RGB_SPACE. If uFlags is RGB_SPACE, the first element corresponds to the new blue upper side average value, the second element to the green, and the last element to the red.
