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
