L_LTIMGSFX_API L_INT L_OceanBitmap(pBitmap, uAmplitude, uFrequency, bLowerTrnsp, uFlags)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uAmplitude;	/* waves magnitude */
L_UINT uFrequency;	/* number of repeated waves */
L_BOOL bLowerTrnsp;	/* flag */
L_UINT32 uFlags;	/* flags */

Reflects the bitmap on an ocean surface.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap to reflect.
uAmplitude	Wave magnitude, in pixels.
uFrequency	Number of repeated waves.
bLowerTrnsp	Flag that indicates the transparency direction. Possible values are:
	Value	Meaning
	TRUE	Transparency increases as you move from the bottom of the bitmap to the top of the bitmap, line by line.
	FALSE	Transparency increases as you move from the top of the bitmap to the bottom of the bitmap, line by line.
uFlags	Reserved for future use. Must be 0.

Returns

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

Comments

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

If the bitmap has a region, the effect will be applied on the region only.

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 in the Document and Medical Imaging toolkits.

To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.

To obtain this effect, the following settings were used with the function:

uAmplitude=15
uFrequency=20
bLowerTrnsp=TRUE

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
