Thanks Tim - That's exactly what I am doing here:
var newFirmSym = new SimpleFillSymbol(SimpleFillSymbol.STYLE_FORWARD_DIAGONAL, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([0,25,255]), 3), new Color([255,255,0,0.5]));
but the FORWARD_DIAGONAL keeps rendering default black . . .
You are right, it doesn't work for me either.
Thanks, I thought I was going crazy. I was hoping to not have to render it in the mxd, but I may not have a choice....
Take a look a this discussion that goes into why you can't apply a color to the different fill patterns.
The hatch patterns cannot be altered via the api because they are images.
Only STYLE_SOLID will use the color provided. STYLE_SOLID and STYLE_NULL are the only "pure" esri/symbol/SimpleFillSymbol(s).
All the other fill options like STYLE_BACKWARD_DIAGONAL, are actually esri/symbol/PictureFillSymbol(s), which use images that are included in the api http://js.arcgis.com/3.7/js/esri/images/symbol/sfs/vertical.png.
The solution, work-around or what have you is to use esri/symbol/PictureFillSymbol with your own custom images.
Thanks Ken, I was looking for that discussion and couldn't find it. I would agree with your work around re the PictureFill, but it also looks like if you reference this js
that it overrides the default behavior.. either way thanks to you both for help-
David
