[OpenLayers-Users] Is it possible to show a subsection (sprite) of an image as a marker?

[Bart van den Eijnden (OSGIS)]

Hi Matt,

not out of the box unfortunately.

This would either require changes to the current renderers (SVG and VML),
or implementing your own custom renderer. I did something like this a
while ago, see:

Best regards,
Bart
