recalculateImageDimensions

Given regional bounds image width and height are computed in order to display a region without distortion.

The Satellite Application Facility on Climate Monitoring (CM SAF)
is a ground segment of the European Organization for the Exploitation of
Meteorological Satellites (EUMETSAT) and one of EUMETSATs Satellite Application
Facilities. The CM SAF contributes to the sustainable monitoring of the climate
system by providing essential climate variables related to the energy and water
cycle of the atmosphere (<https://www.cmsaf.eu>). It is a joint cooperation of eight
National Meteorological and Hydrological Services.
The 'cmsafvis' R-package provides a collection of R-operators for the analysis and
visualization of CM SAF NetCDF data.
CM SAF climate data records are provided for free via (<https://wui.cmsaf.eu/safira>).
Detailed information and test data are provided on the CM SAF webpage
(<http://www.cmsaf.eu/R_toolbox>).
