L_LTIMGSFX_API L_INT L_ImpressionistBitmap(pBitmap, uHorzDim, uVertDim, uFlags)

pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uHorzDim;	/* horizontal size */
L_UINT uVertDim;	/* vertical size */
L_UINT32 uFlags;	/* flags */

Makes a bitmap look like it was painted by an impressionist painter.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap on which to apply the effect.
uHorzDim	Horizontal effect size, in pixels. Possible values are range in between 1 and 100.
uVertDim	Vertical effect size, in pixels. Possible values are range in between 1 and 100.
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.

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.

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.
