Abstract: The present invention includes steps of: acquiring a first image information; making the first image information to have a hidden attribute; acquiring a second image information in a displaying format; acquiring the first image information and the second image information to perform a blending operation for producing a third image information in a displaying format to output to a first display device; editing the second image information in the displaying format through the third image information in the displaying format displayed on the first display device; and drawing the edited second image information to produce a drawn image information in the displaying format, thereby, as editing the second image information, the third image information which is displayed on the first display device and contains the first image information can act as reference, so as to avoid the drawn image information from containing the first image information.

Abstract: The present invention discloses a method for presenting objects of the Windows operating environment on multiple display devices, which is implemented with a series of computer-executable steps, wherein the attribute values of the display regions of multiple display devices (such as the resolutions thereof) and the attribute values of at least one object of the Windows operating environment are used to redefine a restricted display region that may cross multiple display device; via coordinatizing the objects and the display regions of the display devices, the fiducial coordinates of the objects can be moved to the assigned display coordinates inside the restricted display region to present the objects on within the restricted display region. Thereby, the objects can only be moved within the assigned display region of the screens, and the existing/uncreated objects can be moved/assigned to the intended positions or regions.
