public class PQBinReader
extends FormatReader

PQBinReader is the file format reader for PicoQuant .bin files. Please Note: This format holds FLIM data arranged so that each decay is stored contiguously. Therefore, as in other FLIM format readers e.g. SDTReader.java, on the first call to openBytes the whole data cube ( x,y,t) (NB actually t not real-time T) is loaded from the file and buffered On further calls to openBytes the appropriate 2D (x,y)plane (timebin) is returned from this buffer. This is in the interest of significantly improved performance when all the planes are requested one after another. There will be a performance cost if a single plane is requested but this is highly unlikely for FLIM data. In order to limit the size of the buffer, beyond a certain size threshold only a subset of planes (a Block) are retained in the buffer.
