[Gwt-openlayers-users] Projection supported?

[Jon B. <jon...@go...>]

Hi,
Is the Projection class supported in gwt-openlayers?  I can't seem to find
the transform methods.
Thanks,
Jon

Hi Jon,

the method transform isn't implemented yet. I have made it myself and it works. I have ask the admins of the openlayers-gwt-project for code-contribution, but to date I have no answer. I can send you the source-code if you like.

regards

Tino

What I really need is the transform method for the Bounds class.  I've been
trying to implement it in pure JavaScript but can't get it to work (it keeps
telling me my Bounds object doesn't have a "transform" function).

Hey Jon,

the Openlayers.js contains the function transform in the class Openlayers.Bounds. It uses the Projection-class and it should be working. Which version do you use?

Re: [Gwt-openlayers-users] Projection supported?

[Jon B. <jon...@go...>]

I'm using 2.10.  I've solved that problem now, but my transformation still
isn't working.  I've included the proj4js.js library in my project, but the
result is always in EPSG:4326 (I'm trying to project to EPSG:32630).  I
assume the problem is that proj4js isn't finding the projection. I read
Proj4js user guide and it says that it will lookup the projection code on
spatialreference.org but this doesn't seem to be happening...

Does anybody know how to use proj4js with OpenLayers?  My GWT/JavaScript
method is below.

Cheers,

private static native JavaScriptObject reproject(double minX, double minY,
double maxX, double maxY, String source, String dest)/*-{
 var bounds = new $wnd.OpenLayers.Bounds(minX, minY, maxX, maxY);
var sourceProj = new $wnd.OpenLayers.Projection(source);
 var destProj = new $wnd.OpenLayers.Projection(dest);
bounds.transform(sourceProj, destProj);
 return bounds;
}-*/;

Re: [Gwt-openlayers-users] Projection supported?

[<tin...@ar...>]

Hey Jon,

you have to include your projection in your javascript. You can find the code for the proj4js-projection on http://spatialreference.org/ref/epsg/32630/proj4js/

Proj4js.defs["EPSG:32630"] = "+proj=utm +zone=30 +ellps=WGS84 +datum=WGS84 +units=m +no_defs";

I you don't do this the conversion returns the coordinates you have put in.
This should solve yout problem.

regarda

Tino
