Trouble with EPSG:2154

[kolxo]

Hi,

I have troubles using the following code

map = new L.Map('map', {
  crs: L.CRS.proj4js('EPSG:2154'
    ,'+proj=lcc +lat_1=49 +lat_2=44 +lat_0=46.5 +lon_0=3 +x_0=700000 +y_0=6600000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs'
    ,new L.Transformation(1, 0, -1, 0))
  });

I just add a Canvas layer such as :

canvasTiles.drawTile = function(canvas, tilePoint, zoom) { var ctx = canvas.getContext('2d'); ctx.rect(0,0, 256,256); ctx.stroke(); ctx.fillText('(' + tilePoint.x + ', ' + tilePoint.y + ')',5,10);

            });

Such layer draw a grid with tile coord on vanilla Leaflet. But with the map on EPSG:2154, nothing happen. I try to play with transformation parameters without success.

Is there something wrong with my map declaration ?

Thanks in advance for your support

Hey, I am having the same problem. (using Kartena's proj4leaflet lib) I have tried different parameters with transformation ..

Have you figured out how to add EPSG 2154 to LeafLet ?

Hi,

No I'm sorry, Currently I'm not able to add EPSG 2154 with proj4Leaflet. I use directly proj4j before displaying data. It's tedious and I don't know why it doesn't worK.

Hi,

Same problem for me. I managed to set my map in 2154 projection, and display some WMS layers. But no success with Tile Layers. I've tried a lots of transformation matrix, and one time i managed to display the tiles on a specific zoom. But the matrix was only correct for that zoom level...

Do you know if is really related to 2154 or to any local projection ?

It works well with Leaflet 0.3.1, check out the following code : http://blog.mathieu-leplatre.info/leaflet-tiles-in-lambert-93-projection-2154.html

However the map is blank with Leaflet 0.4.2... tilepoints look out of bounds (unprojected?)

[leplatrem]

Took me a while to figure out that Leaflet 0.4 now expects a scale() method in CRS classes.

Could fix easily setting scale attribute to the resulting crs object.

Yep there was a breaking change between Leaflet 0.3 and 0.4. You now need to set the scale function on the crs object instead of on the map object like @leplatrem says. Closing, but feel free to comment if this didn't solve the issue.
