Abstract

A method of editing compound documents containing both text and non-text components, such as image, graphics or digital-audio objects. The method transforms a compound document in modified revisable form architecture to an internal editing format. In the transformation process, non-text components are recognized and catalogued in a component index generated for the compound document in the internal editing format. The component index contains information on the characteristics of the non-text components and describes the size, location and type of each non-text component. A reference or referencing control to the non-text component is placed in the text at the location the user wishes to print or display the non-text component in the final document. Through the invention, it is possible to represent and display a single non-text component multiple times within the compound document while storing only a single physical representation of the non-text component within the document. The method also provides a improved means of displaying the characteristics of the non-text component to the user, particularly where an alphanumeric display is used.

Claims

1. In a data processing system, including a central processing unit, a random access memory, and a bulk storage device, and further including a display device and a dot printer, all interconnected by a system bus, a method for constructing a first compound document carried out by said central processing unit operating upon sets of instructions stored in said random access memory, said compound document including both alphanumeric text and a non-text component, the method comprising the steps of:

organizing a first database representation of said first compound document to include an alphanumeric text portion, and a non-text component;

reading said first document database into said random access memory from said system bus;

transforming said first document database into an internal editing format, said format containing said non-text component in a single location;

constructing a first component index which includes an index entry associated with said non-text component of said first document database said index entry in said component index having a set of control parameters which include an indication of a component type, a component name, and said location of said non-text component in said random access memory;

placing a referencing control in said alphanumeric text where said non-text component is to be printed in said compound document;

whereby a compound document containing both alphanumeric text and non-text components is generated.

2. The method of claim 1, which further comprises the step of:

displaying a representation of said document database on an alphanumeric display which includes a place marker icon corresponding to said non-text component positioned in said document to indicate where said non-text component is to be printed in said document.

3. The method of claim 2, which further comprises the step of:

displaying a page marker for each page so that the placement of said non-text component in said compound document is evident to a user.

4. The method of claim 1, which further comprises the step of:

printing said document on said dot printer by referring to said document database and positioning the alphanumeric text where indicated and positioning said non-text component where indicated in said document database.

5. The method of claim 1, which further comprises the step of:

displaying said non-text component on a display device capable of displaying said non-text component.

6. The method of claim 1, which further comprises the step of:

displaying a menu associated with said component index which includes the control parameters listed for said non-text component.

7. The method of claim 1, which further comprises the steps of:

changing the control parameters for said non-text component;

updating said component control to reflect said changes in the control parameters.

8. The method of claim 1, wherein said database representation of compound documents includes a multiple of referencing controls to said non-text component in said alphanumeric text and a single physical representation of said non-text component, whereby said non-text component is included a multiple of times in said compound document.

9. The method of claim 1, which further comprises the step of:

operating on said non-text component with a vector graphics program stored in said random access memory in a vector graphic operation to be performed in accordance with information entered at said referencing control.

10. The method of claim 1, wherein said non-text component is a dot-image depiction.

11. The method of claim 1, wherein:

said non-text component is a vector graphics depiction.

12. The method of claim 1, wherein:

said non-text component is a digital-audio representation.

13. The method of claim 1, which further comprises the step of combining the non-text components of said first compound document and a second compound document said combining step comprising the steps of:

reading a second document database representing said second compound document into said random access memory from said system bus, transforming said second document database into internal editing format and generating a second component index associated therewith;

defining a source non-text component in said second component document;

defining a target reference location for said source non-text component in said first compound document where said source non-text component will appear in said first compound document;

placing a referencing control in said first document database for said non-text document at a position desired for ultimate insertion of said non-text component;

referring to said second component index to determine where said source non-text component is in said second document database;

extracting said source non-text component from said second document database and copying said non-text component into said first document database;

adding an entry to said first component index containing a component type for said source non-text component, a location in said random access memory for said source non-text component in said first document database;

whereby a portion of said second document database has been incorporated into said first document database to produce a modified compound document.

14. The method of claim 13, wherein the only action performed by the user is placing said referencing control in said first document by copying said referencing control from said second document into said first document.

15. In a data processing system including a CPU unit, a memory, a bulk storage and a workstation all interconnected by a system bus, said workstation including a keyboard for inputting command and working text information to said data processing system and a display screen, an improved method of transforming a compound document data stream that produces a dynamic compound index of non-text components within a sequentially ordered component document data stream where each non-text component is contained in a single location, said improved method carried out by said CPU operating upon sets of instructions stored in said memory in response to user actions and comprising the steps of:

scanning said sequentially ordered compound document data stream for non-text components;

extracting non-text component characteristics for each said non-text component from said sequentially ordered compound document data stream;

creating a component index in said sequentially ordered document datastream, said component index having index entries for each said non-text component, each said index entry including a listing of component type, component name and component location in said memory for each said non-text component;

and updating said component index in said sequentially ordered component document datastream.

16. The method of claim 15 which further comprises the step of displaying said sequentially ordered document datastream as a compound document which includes alphanumeric text and non-text component on said display screen.

17. A text processing system for constructing a compound document which includes both alphanumeric text and a non-text component comprising:

a random access memory connected to a system bus;

means to organize a database representation of said compound document resident in said random access memory, said compound document to include an alphanumeric text portion and a non-text component;
