BUG: ND2 files - x,y position of the different multi points returned in the wrong order

[bramalingam]

QA 9529,

nd2 with 80 multipoints, 2 time-points and 3 channels.
When trying to retrieve the x,y position of the different multipoints, the locations are returned in the wrong order and some are missing.
Depending on how many time-points other nd2 had, the return pattern of locations seemed to differ. For only one time-point the correct locations are returned in the right order with bioformats version 5.0.4

Script used for checking,

clear all;close all;

r = bfGetReader('/Volumes/ome/apache_repo/9529/PositionInfo_z1_c3_t2_multipoints80.nd2');
metadata = r.getMetadataStore();
zSection =0;

for channel = 0:2

for time = 0:1

figure;
planeIndex = loci.formats.FormatTools?.getIndex(r, zSection, channel, time);

% planeIndex=0;

for positionIndex=1:80

xPosition(positionIndex) = double(metadata.getPlanePositionX(positionIndex-1, planeIndex));
yPosition(positionIndex) = double(metadata.getPlanePositionY(positionIndex-1, planeIndex));
disp(positionIndex)
hold on;

if time>0

plot(xPosition,yPosition,'r*-');

else

plot(xPosition,yPosition,'b*-');

end

end
title(num2str(channel)?)

end

end

Moving to 5.1.1 for triage.

Should be fixed with: ​https://github.com/openmicroscopy/bioformats/pull/1717
