CHAR_DESC ExtractFlexFeatures	(	TBLOB *	Blob,
		LINE_STATS *	LineStats
	)

Allocate a new character descriptor and fill it in by calling all feature extractors which are enabled.

Parameters:

	Blob	Blob to extract features from
	LineStats	Statistics about text line Blob is on

Returns:

Structure containing features extracted from Blob.

void InitFlexFXVars

(

)

Add any control variables used by the feature extractors to the variable system; including the enable flag for each individual extractor.

Parameters:

none

Returns:

none

This routine needs to create a separate name for the enable for each feature extractor and allocate a string to contain that name. This is necessary since the "variables" routines do not create copies of the string names passed to them.
