E57Exception: element value out of min/max bounds (ErrorValueOutOfBounds)

[iegorval]

I am using Data3DPointsDouble and trying to write any intensity value >= 266 causes E57Exception: element value out of min/max bounds (ErrorValueOutOfBounds).

Can anyone explain this? I do not see this documented anywhere.

Moreover, if I set intensityLimits.intensityMinimum and intensityLimits.intensityMaximum to min/max based on the data, it still fails. However, if I set intensityLimits.intensityMinimum to 0 but intensityLimits.intensityMaximum to actual max, it works. Seem like a pretty random behavior to me and I managed to fix it only by chance.

So the first thing is that intensityMinimum/Maximum seem to be used incorrectly by the existing "simple API". These are not the min/max of the data, but the min/max that the sensor can produce (see the standard 8.4.19.2). So the "simple API" shouldn't be setting them when it's filling in the other min/max data. That should be removed from _fillMinMaxData in E57SimpleWriter.cpp.

I'm not sure why your use-case is failing though. intensity is a double, and it looks like you're hitting a char limit. If you could write a test case for the test suite that demonstrates what you're seeing, that might help point at the issue.
