L_BOOL bTransparent;	/* flag that indicates whether to make the bitmap transparent */
L_UINT uFlags;	/* reserved for future versions */

Sets bitmap objects to use a transparent color. A transparent color is not painted when the image is painted. This function is available in the Document/Medical Toolkits.

Parameter	Description
bTransparent	Flag that indicates whether to make the bitmap transparent. Possible values are:
	Value	Meaning
	TRUE	Make the bitmap transparent
	FALSE	Do not make the bitmap transparent. This is the default.
uFlags	Reserved for future versions, use 0.

Returns

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

Comments

Only Point and Stamp objects that are using a bitmap can be set to use a transparent color. By default the transparent color is white (0x00FFFFFF). In order for the transparent bitmaps to be painted properly the LTEFX14n.dll needs to be present for WIN32. If the appropriate DLL is not present, the transparent bitmap stamps will be painted as non-transparent bitmap stamps.

The next stamp created will be transparent.
