#include "ltwrappr.h"

L_INT LBitmap::PlasmaFilter(PlasmaInfo, uFlags = 0)

Applies color patterns that blend into each other like plasma.

Parameters

pPLASMAINFO PlasmaInfo

Pointer to a PLASMAINFO structure that contains information about the plasma effect.

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

Comments

As an example, suppose you call the LBitmap::PlasmaFilter function, using a PLASMAINFO.uOpacity value of 0, which means that no image is to be used, and you use the following settings:

Parameter	Value
PLASMAINFO.uShift	0
PLASMAINFO.uOpacity	0
PLASMAINFO.uSize	1000
PLASMAINFO.uFlags	PLSTYP_RANDOM1 \| PLSCLR_RGB2
