What's the meanings of the prameters of AIRasterSuite.ExtractOutline

Question

From the Illustrator SDKs header file, we can get the declaration of AIRasterSuite.ExtractOutline() as following:
/** Extracts an outline path from the image data, and enumerates the curves to the supplied callback functions.
@param raster An art object of type \c #kRasterArt.
@param params Parameters that control the curve fitting, or \c NULL
to use defaults.
@param consumer The developer-defined callbacks.
AIAPI AIErr (*ExtractOutline) ( AIArtHandle raster, const AIRasterOutlineParams* params,
AIRasterOutlineConsumer* consumer );
The parameter AIRasterOutlineParamss definition is following:
/** Parameters for controlling the curve fitting used when outlining a raster.
See \c AIRasterSuite::ExtractOutline() */
typedef struct AIRasterOutlineParams
int noiseFilterDegree;
double cornerAngleTolerance;
double smoothnessTolerance;
double fidelityTolerance;
} AIRasterOutlineParams;
[Question]
[Q1] What are the exact meanings of the four members of AIRasterOutlineParams? And whats the valid value range for the four parameters.

Answer 1

And when you get an Android or iPhone, don't you contact your carrier for front-line support, just like with a BlackBerry?  And does Android and iPhone offer support forums such as this one?  (Perhaps they do, I'm just asking.) 
Fact is, when you download an app from AppWorld, the "contact support" button does work for apps developed by third-party developers.  Because AppWorld itself is a BlackBerry product, that would go through your carrier or here.
