发明名称 Method and apparatus for producing a semi-transparent cursor on a data processing display
摘要 A method and apparatus which produces a semitransparent cursor for a video display presenting simultaneous viewing access to both the cursor and the underlying image information. At the on-screen location of the cursor, the viewer is able to simultaneously view and distinguish between the cursor and the underlying graphical data. In one form, the method includes the steps of obtaining the red, green, and blue video pixel data for each pixel representing at least a portion of the cursor; halving the numerical value of each datum of red, green, and blue video pixel data; injecting a binary value into the most significant bit of each datum to obtain modified red, green, and blue video pixel data; and providing modified red, green, and blue video pixel data to a video display.
