Abstract

A number of items of data from a data source (12) can be processed, and then supplied to a data destination (16-17). The data can include image data, text data, numeric data or some other type of data, or a combination of these types of data. The processing of the data is controlled by a project definition (14, 71, 101), which includes a plurality of modules selected from a variety of available modules. The modules have input and output ports, and the project definition includes binding information which relates input ports to output ports. The binding information can include a conditional binding (128), which supplies data to an input port from a selected one of two or more output ports, in dependence on a condition. A separate feature is that, if data obtained in a given format from an output port is being supplied to an input port which expects data in a different format, the data is automatically converted to the format expected by the input port.

Claims

wherein facilitating preparation of said project definition comprises displaying a project window that includes a graphical representation of said project definition and allowing a user to modify said project definition by interacting with said graphical representation using a pointing tool; and

wherein execution of said project definition operates at least in part to manipulate a graphical aspect of said image data.

5. A computer-readable medium according to claim 4, wherein said program is operable when executed to facilitate formulation of said specified condition to be a function of data which is available to said conditional binding from at least one of said output ports in said set.

6. A computer-readable medium according to claim 4, wherein said program is operable when executed to facilitate said preparation of said project definition by having a user identity, for each said conditional binding, said input port therefor, said set of output ports therefor, said specified condition therefor, and a relationship between said specified condition and each said output port in said set.

22. A computer readable medium according to claim 4, wherein:

said project window further includes a list of functions, sources, and destinations; and

allowing said user to modify said project definition by interacting with said graphical representation using said pointing tool includes allowing said user to;
