Masks Fade creation
	Fade_Masks Creates a new Masks fade object. myFade = new Fade_Masks( Type, Blending_Mode, bReverse ) myFade = new Fade_Masks( Type, Blending_Mode ) myFade = new Fade_Masks( Type ) myFade = new Fade_Masks( ) Return value Newly created fade object. Parameters Type Pointer to a mask function; This can be one of your own (takes a surface and a value from 0 to 1 and draws the desired shapes onto the surface) or one of the following: Masks_Circle Simple circle which expands to fill the screen Masks_Triangle Triangle pointing left which expands to fill the screen Masks_TriangleB Same as Triangle, but faces right Masks_Square A square which expands to fill the screen Masks_Rectangle A rectangle which expands to fill the screen Masks_Diamond A diamond which expands to fill the screen Masks_Star A star which rotates and expands to fill the screen Masks_LinesUp Diagonal lines (NW/SE) fill the screen Masks_LinesDown Diagonal lines (NE/SW) fill the screen Masks_Cross A mix of LinesUp and LinesDown Masks_TopBottom Diagonal bar (NE/SW) moves in from top+bottom Masks_BottomTop Diagonal bar (NW/SE) moves in from top+bottom Masks_BallTopBottom Same as TopBottom but with balls instead of bars Masks_BallBottomTop Same as BottomTop but with balls instead of bars Masks_BallAll 4 circles; one in each corner; expand to fill the screen Masks_BallFive A mix of BallAll and Circle Masks_CircleCrossOver Top-left and bottom-right have balls expanding, while top-right and bottom-left have a mathematical pattern Masks_TopBottomWithLines It's just getting silly now Masks_BallTopBottomWithLines Try the fades for yourself and see what you think :P Masks_BottomTopWithLines Same as TopBottomWithLines but mirrored Masks_BallBottomTopWithLines Same as BallTopBottomWithLines but mirrored Masks_OpenH Frame splits vertically and opens Masks_OpenV Frame splits horizontally and opens Masks_Eye An eye-like effect Masks_Magic A strange effect. Note that you should not use Blending_Off with this. Blending_Mode Pointer to a blending function; This can be one of your own (takes a value from 0 to 1 and returns a value from 0 to 255) or one of the following: Blending_Off No blending used Blending_Linear Linear blending used (default) Blending_Square Blending amount related to the square of the time Blending_Root Blending amount related to the square root of the time Blending_Sine Starts and ends solid Blending_Log Logarithmic rise in opacity Blending_Inverse Not sure what this does Blending_Smooth More complex version of linear. Gives a more natural result. Blending_Power Interesting blending based on the square of the time Blending_Sine2 Again, more interesting, based on the sine of the time Blending_Electric Slow flashing which gets faster towards the end of the fade Blending_Bounce Blending "bounces" through the fade bReverse TRUE to play the transition backwards. FALSE (default) to play it normally Comments When making your own blending functions, it is recomended to only return integers from 0 to 255 to avoid unexpected behaviour. This can be achieved by adding Max(Min(Round( [result] ),255),0) when the value is returned (replace [result] with your variable) This is not necessary if you know the value will be safe. It is possible, though fairly pointless, to change the blending mode later on through SetFade. JAM © 2005 no one in particular Project started by David Evans in 2005
