Abstract
A method and system are provided for detecting transparency simulation formulated by an application in a rendering device. The system includes a node structure construction component for saving each drawing function in a node with an associated node type and node state. The system further includes a node structure constructed from the saved nodes and traversal components for traversing the node structure. The traversal components include a type check mechanism for determining a saved type of each node in the structure and a state check mechanism for finding a saved state. The system detects the transparency simulation upon finding a predetermined node type and a predetermined node state.
