void ClearCharNormArray	(	INT_TEMPLATES	Templates,
		CLASS_NORMALIZATION_ARRAY	CharNormArray
	)

For each class in Templates, clear the corresponding entry in CharNormArray.

Parameters:

	Templates	Specifies classes currently defined
	CharNormArray	Array to be cleared

Returns:: none

CharNormArray is indexed by class indicies (as obtained from Templates) rather than class id's.

Note:: Exceptions: none

void ComputeIntCharNormArray	(	FEATURE	NormFeature,
		INT_TEMPLATES	Templates,
		CLASS_NORMALIZATION_ARRAY	CharNormArray
	)

For each class in Templates, compute the match between NormFeature and the normalization protos for that class.

Parameters:

	NormFeature	Character normalization feature
	Templates	Specifies classes currently defined
	CharNormArray	Place to put results

Returns:: none (results are returned in CharNormArray)

Convert this number to the range from 0 - 255 and store it into CharNormArray. CharNormArray is indexed by class indicies (as obtained from Templates) rather than class id's.

Note:: Exceptions: none
