public void setResource(String id, byte[] img)

Assigns a resource ID to a memory block to allow it to be referenced using a resource path.

Many ChartDirector features, such as BaseChart.setBgImage and the <*img*> tag in CDML, expect a file or resource path for loading an image. If the image happens to be in memory, such as if the image is retrieved from a database, setResource can be used to assign a resource ID to the memory. It can then be referenced using "@/res_id", in which res_id is the resource ID.

The assigned resource ID is only valid for the DrawArea object of which this method is called. Use Chart.setResource to assign a resource ID that is valid for all ChartDirector objects.

This method only saves a to the memory. It does not copy the memory. You must ensure the memory contains valid content for as long as the resource is being used.
