314 Appendix A

Constants and Predeclared Variables

These are the predeclared variables included in FXScript. They can be used wherever

appropriate in your scripts and do not need to be declared in the script code. You can assign

values to them as necessary in your scripts.

Highlight

Highlight(destImage,

centerPoint,

angle, width,

softness, dither,

gaussian,

foreColor,

backColor,

aspect)

Paints a specular highlight band

in the destination image buffer,

using the speciﬁed center point

and angle as the highlight line.

“Width” and “softness” deﬁne

the size of the highlight band,

and “color” speciﬁes the color.

If the value for “dither” is true, a

random dither is applied to the

highlight gradient, making it

smoother over large areas. If

“gaussian” is true, the gradient

will have a Gaussian fall-off,

which looks more natural when

used for specular highlight, or

when two highlights are

screened together.

CircleLight

CircleLight(destImage,

centerPoint,

width, softness,

aspect, dither,

gaussian,

foreColor,

backColor)

Creates a circular highlight

outwards from “centerPoint”

RandomNoise

RandomNoise(destImage,

alphaMin,

alphaMax, redMin,

redMax, greenMin,

greenMax,

blueMin, blueMax,

makeColors)

Randomizes the color of all the

pixels in the destimage buffer,

according to the bounds set by

the min and max values for each

channel

Assert

Assert(value)

Stops the script with an error
