virtual L_INT LBitmap::DrawStar(pStarInfo)

/*pointer to a structure */

Draws a star on the bitmap. This function is available in the Raster Pro and above toolkits.

Parameter	Description
pStarInfo	Pointer to an LPSTARINFO structure that contains star information.

Returns

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

Comments

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 only in the Document/Medical toolkits.
