L_WindBitmap

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_WindBitmap (pBitmap, uDim, nAngle, uOpacity)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uDim;	/* effect size */
L_INT nAngle;	/* rotation angle */
L_UINT uOpacity;	/* opacity */

Creates thin lines, directed along the specified angle, on the specified bitmap. This function is available in the Raster Pro and above toolkits.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap on which to apply the effect.
uDim	Size, in pixels, of the thin lines used to create the wind effect. Possible values range from 1 - 100.
nAngle	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).
uOpacity	Density, in pixels, of the thin lines used to create the wind effect. The valid range is from 0 to 100.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
