Cast to double may be needed

	double rx = width / 2;
	double ry = shapeType == CIRCLE ? rx : height / 2;

Since width and height are ints, the equation is done with Integer accuracy and not Double accuracy.

To get Double accuracy from the equations, a double cast is needed

Maybe
double rx = (double) width / 2;
double ry = shapeType == CIRCLE ? rx : (double) height / 2;

Thanks @scuniff and agreed that the width and the height should be casted to double to handle all scenarios. In practice, all the FV1000 samples in the OME curated data repository have even values for their width and height so this rounding issue never came up as part of the testing.

Feel free to open a Pull Request with your proposed changes and we can check it using the nightly CI builds. As a bonus, if you happen to have a sample FV1000 dataset allowing to test this condition, feel free to upload it to https://zenodo.org/
