Re: [mapguide-users] Proj4js

Yes, I have noticed that.  I usually manually assign my proj4 before doing
any transform:

i.e.

Proj4js.defs[EPSG:3857]=+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0
+lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs;

var dest = new Proj4js.Proj('EPSG:3857');
var source = new Proj4js.Proj('EPSG:4326'); 

Proj4js.transform(source, dest, point);

[mapguide-users] Proj4js

[swimming123]

I just need a conversion between EPSG:4269 and Google Web Mercator in client
side, then I copy a proj4js-combined.js from this folder:
C:\Program Files\Autodesk\Autodesk Infrastructure Web Server Extension
2013\www\fusion\lib\Proj4js  
Open the proj4 javascript file and find it defines EPSG:3875 as Google
Mercator; I think it must be wrong, Google Web Mercator suppose EPSG: 3857;

Of course, I use EPSG:900913 to do the calculation to avoid this issue. For
curiosity, I did  test using EPSG:3857 or EPSG:3875, both not working.
