Abstract
Techniques for management of drawing resources are described. In an implementation, a reference count numeral may be associated with a drawing resource stored in cache memory. One may be added to the reference count numeral each time a new drawing resource is added to memory. In addition, one may be removed from the reference count each time an existing drawing resource is removed from the memory. Also, the drawing resource may be maintained in the cache memory when the reference count numeral is greater than zero.
