[OpenLayers-Users] Drawing a point feature with image and background color..

[Carlos Krefft]

"I'm drawing features with images defined by the externalGraphic property..
Then.. I can't use the fillColor.. ?"

 

You cannot use fillColor with an externalGraphic as it says in the
documentation . But your original question states you will be using TWO
features "I'm drawing two elements in the same position".

 

So use fillColor for your background feature and externalGraphic for your
foreground feature.

 

"Or is there any other way to draw the feature withous using
externalGraphic?"

 

Yes, you can simply omit the externalGraphic and the feature will draw
without the a graphic, just with the style.

Uhm..

 

But.. as seen in this link..

http://docs.openlayers.org/library/feature_styling.html 

 

"fillColor

Default is #ee9900. This is the color used for filling in Polygons. It is
also used in the center of marks for points: the interior color of circles
or other shapes. It is not used if an externalGraphic is applied to a
point."

 

I'm drawing features with images defined by the externalGraphic property..
Then.. I can't use the fillColor.. ?

 

Or is there any other way to draw the feature withous using externalGraphic?

 

Thanks...

Use fillColor.

.

fillColor: "#FF5500",

fillOpacity: 0.7,

.

Hi, 

 

I would like to know if it is possible to draw a point feature with a
background color..

 

I define a style like that:

 

ImgStyle = {

        externalGraphic: imgURL,

        label: text,

        labelXOffset: "0",

        labelYOffset: "-10",

        fontColor: txt_colfont,

        fontSize: "10px",

        fontFamily: "Arial",

        fontWeight: "bold",

        pointRadius: 10,

        labelAlign: "cm",

        labelPadding: "3px",

        labelBackgroundColor: txt_colback,

        labelBorderColor: "#cfcfcf",

        labelBorderSize: "1px"

    };

 

And what I would like to do, is draw a background to the image..

 

By now, I'm drawing two elements in the same position, one is the point with
the externalGraphic, and the other one is the same but without the
externalGraphic and with a background color.. With this I can see the effect
of a background under the image..

 

But, I would like to draw as a unique element... Because I'm loading a large
amount of markers to the map.

 

And also, I would like to apply a cluster strategy to the layer.. And
drawing the background and the image as separate features modifies the
clustering..

 

Thanks!
