uRAmp

Value that represents the amplitude of the master channel or the amplitude of the red channel. If the bitmap is grayscale, this parameter represents the amplitude of the master channel. If the bitmap is color and FL_MUL or FL_LINEAR_QUADRATIC are set in uFlags, this parameter represents the amplitude of each channel. If the bitmap is color and FLB_ADD is used, this represents the amplitude of the red channel. This value is an integer with a value greater than or equal to 0. This value will be multiplied with the results of the selected function (sine, cosine, user buffer , …). The results of the multiplications are then added to the pixel values. These values as well as the real buffer values are from –1 to 1. Possible values are from 0–100.
