Ellipsoid conversion, elevation Z not calculated

[ruyi7952]

reproduction process,
a calculates the seven-parameter Bursa model
b selects the xyz coordinate system in ms,camera selects wgs84 ,input the seven-parameter
c converts pos to xyz and to check pos

There is no change in z, and z will change in the software that calculates the seven parameters.

Is it possible to add a matching seven-parameter calculation function and save the results as a prj file?

Different models have different definitions of parameters. As long as there is one method, seven parameters compatible with PS can be obtained, which can properly solve this problem.
