L_LTIMGSFX_API L_INT L_WindBitmap (pBitmap, uDim, nAngle, uOpacity, uFlags)
Creates thin lines, directed along the specified angle, on the specified bitmap.
Pointer to the bitmap handle that references the bitmap on which to apply the effect.
Size, in pixels, of the thin lines used to create the wind effect. Possible values range from 1 - 100.
Direction of the thin lines used to create the wind effect, in hundredths of a degree. Possible values range form 36000 to 36000. (The value in degrees is nAngle divided by 100).
Density, in pixels, of the thin lines used to create the wind effect. The valid range is from 0 to 100.
Reserved for future use. Must be 0.
