ReferenceLine can't display

[DMIAOCHEN]

I was try with the latest version, but it's still has no referenceLine, it fine in RadiAntViewer

It's may something wrong in calculate referenceline when i debug the source, but i can't resolve it, there is dicom file in the end

@ladeirarodolfo thanks! but it still doesnt work when i update cornerstone-math to v0.1.9, currently i solved this problem like this, but i am not sure whether it is a good solution:

from math point of view you should not 'double this distance'. Javascript can cause some unwanted behaviors when doing some math calculations: My advice for you is to plot graph and see if considering the 'line' and 'rect' variables there are at least 2 intersection points. I.e before you go into implementation stuff try to see if it makes sense on real world, then try to look for rounding issues

If I have the data I can help you with some debugging
