| SUMMARY: FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
A renderer to draw vector graphics like line, polygons, circles and so on a map.
The renderer is responsible to project the data (which is specified in map coordinates)
on the map and refresh the graphics after move and zoom events.
The map renderer is based on IWGraphicsRenderer and so browser independent (VML in Internet
Explorer 6-8, SVG otherwise).
Example:
var attributes = { fill: 'red', stroke: 'black', strokeDashStyle: 'dashed' };
var renderer = new IWMapRenderer(map);
renderer.drawCircle(map.getCenter(), 1000, attributes); // draw a 1 km circle in the center of the map
renderer.render();
| Property | Description | Value | Elements |
|---|---|---|---|
| fill | the fill or text color | CSS color description, e.g. #ff0000 or blue | circle, ellipse, polygon, rectangle, rounded rectangle, text |
| fillOpacity | the opacity of the fill color | value between 0 (transparent) 1 (opaque) | circle, ellipse, polygon, rectangle, rounded rectangle |
| stroke | the stroke color | CSS color description, e.g. #ff0000 or blue | all |
| strokeOpacity | the opacity of the stroke color | value between 0 (transparent) 1 (opaque) | all |
| strokeWidth | the width of the stroke in pixels | number | all |
| strokeDashStyle | the style of the stroke | solid, dashed, or dotted | all |
| strokeLinejoin | the style of line joins | round, bevel, or miter | all |
| strokeLinecap | the style of line ends | round, butt, or square | all |
| fontFamily | the font family to render text | e.g. sans-serif or Helvetica | text |
| fontStyle | the font style to render text | e.g. italic or normal | text |
| fontSize | the font size to render text | e.g. 14px | text |
| fontWeight | the font weight to render text | e.g. bold or normal | text |
| textDecoration | the decoration to render text | e.g. underline, overline or line-through | text |
This class is part of the module graphics.
