Member Function Documentation

int DiBaseLUT::compare ( const DiBaseLUT lut) [protected]

compares current LUT with specified LUT

Parameters:
lutLUT 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
