int DiBaseLUT::compare ( const DiBaseLUT * lut )

protected

compares current LUT with specified LUT

Parameters

lut	LUT to be compared with the current one

Returns: true if LUTs are not equal (1 = invalid LUT, 2 = descriptor differs, 3 = data differs) false (0) otherwise

Uint32 DiBaseLUT::getAbsMaxRange ( ) const

inline

get absolute value range of the LUT entries.

The maximum value which could be stored with the specified bit depth is calculated.

Returns: absolute range of LUT entries
