static Bool casa::LatticePADisplayData< T >::useStriding	(	const IPosition &	shape,
		IPosition &	stride,
		uInt	maxPixels = `1000000u`,
		uInt	minPerAxis = `20u`
	)		`[static]`

Aids updateHistogram() by computing a stride to use for efficiency when computing histograms (could be used elsewhere too).

Input parameter 'shape' is the shape of the original lattice or array. Return value indicates whether striding should be used; if so, the recommended stride is returned in the 'stride' parameter. maxPixels is the desired maximum number of elements in the sub-lattice that would result from using the returned stride (may be exceeded because of minPerAxis requirements, or in any case by a few percent). A stride greater than 1 will not be returned for an axis if it would make the length of that axis in the strided sub-lattice less than minPerAxis.
