Method and system for redirection of transformed windows

A method for redirecting an input device message from an input device to an application via a transformed window on a display, wherein the transformed window is an application window that has been transformed on the display by a transformation matrix, the method comprising:

• receiving the input device message from the input device at an input device location point on the display;
• determining whether the location point is within the transformed window;
• if the location point is within the transformed window, performing an inverse transform on the location point into its logical coordinate system coordinates;
• performing a hit test on a new frame region in the logical coordinate system;
• and
• communicating the device message to the application.

A system for maintaining an application window on a display that has been transformed by a transformation matrix into a transformed window transparent to an application that originated the application window, the system comprising:

• a desktop window manager on a computer system which transforms a window transmitted by the application for display to a transformed window on the display;
• a redirection transform application interface coupled to the manager, wherein the redirection transform application performs an inverse transformation that results in a new frame region and performs hit detection on the new frame region;
• and
• an external input coupled to the desktop window manager, wherein messages to and from the application pass through the transform interface to and from the manager to maintain transparency between the transformed display window and the application.

A computer storage medium encoding a computer program of instructions for performing a method for redirecting an input device message from an input device to an application via a transformed window on a display, wherein the transformed window is an application window that has been transformed on the display by a transformation matrix, by a computer system, said method comprising:

• determining a bounding rectangle bounding the window transformed by the transformation matrix;
• determining whether the input device point is within the bounding rectangle;
• and
• performing an inverse transformation on the input device location point if the input device point is within the bounding rectangle, wherein performing the inverse transformation results in a new frame region;
• and
• performing a hit test on the new frame region.
