ABSTRACT:
A method and apparatus for providing picture generation and control features using a graphical data flow environment. The present invention includes a plurality of virtual instruments or VIs that can be used by themselves or in combination to create pictures that are then displayed via a picture control. Each picture VI includes a corresponding picture icon that is placed in a block diagram. Picture VIs include a unique picture data type that is used to store associated drawing instructions. A picture VI receives as an input an existing picture in the form of a picture data structure having zero or more drawing commands. The picture VI appends its respective drawing commands to the picture data structure and outputs this new data structure to subsequent picture VIs or to the picture control. The picture drawing element of the present invention is implemented as a picture control that appears on the front panel of a virtual instrument. The picture control is a general purpose graphics display control and can be used to display any number of rectangles, lines, points, ovals, arcs, and text. This control can be used to represent data as, for example, pie charts, smith charts, and solid three-dimensionally rendered objects that are not suited for other kinds of graphs. In addition, the picture control can be used to create graphical images as desired for general purpose programming. The picture produced by one picture VI can be passed to subsequent VIs to create elaborate displays. The picture control used to display a picture includes a plurality of data controls that can be used by a user to affect the picture displayed by the picture control. The data controls are programmatically designed by the user for the picture being created. In addition, the user can create a block diagram containing a number of picture VIs that create a desired picture and can use this block diagram as a subVI in other larger virtual instruments.
