Detailed Description

Changes the intensity of a 24 or 32 bpp bitmap. Applies the factor intensityFactor = 1.0 + csupp * pow((v-m_offset), m_exponent) with csupp = intensity/pow(255.0, m_exponent); on the v-Value of the image after a HSV transform. The bitmap stays unchanged for intensity = 20, offset = 128, exponent = 1.
