Constructor Detail
- Transformer
```
public Transformer(double centerX,
                   double centerY,
                   float paperWidth,
                   float paperHeight,
                   double scale,
                   int dpi,
                   DistanceUnit unitEnum,
                   double rotation,
                   java.lang.String geodeticSRS,
                   boolean isIntegerSvg,
                   boolean strictEpsg4326)
```
  Parameters:
  
  centerX - geographic center in projection - x
  
  centerY - geographic center in projection - y
  
  paperWidth - e.g. map width in pt on the PDF
  
  paperHeight - e.g. map height in pt on the PDF
  
  scale - e.g. 10000 if scale is 1:10,000
  
  dpi - as selected in request
  
  unitEnum - the distance unit of the map e.g. DistanceUnit.M for meters
  
  rotation - the rotation of the map per the request
  
  geodeticSRS - if not null then it is a the srs to use with the geodetic
  
  strictEpsg4326 - if true then EPSG:4326 should interpretted as lat/long otherwise use the "incorrect" long/lat
