◆ getName()

std::string BmpPaletteSampleValue::getName ( void ) const
virtual

return a short name uniquely identifying this sample value

Implements SampleValue.

◆ getNearestTargetSampleValue()

SampleValue * BmpPaletteSampleValue::getNearestTargetSampleValue ( EmbValue t) const
virtual

get the nearest (with the least distance to this sample value) sample value whose embedded value equals the specified target

Parameters
tthe target embedded value

If two or more target sample values have equal distance each of them should be returned with equal probability.

The returned SampleValue object should be deleted by the callser.

Implements SampleValue.

◆ getRed()

BYTE BmpPaletteSampleValue::getRed ( void ) const
inlinevirtual

get the red color component

Implements BmpSampleValue.
