JpegSampleValue::JpegSampleValue | ( | int | c | ) |
SampleValue * JpegSampleValue::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
t | the target embedded value |
The returned SampleValue object should be deleted by the callser.
Implements SampleValue.

calculate the distance between the sample value s and this sample value
s | a sample value of the same type as this |
Implements SampleValue.
std::string JpegSampleValue::getName | ( | void | ) | const [virtual] |
return a short name uniquely identifying this sample value
