As described above, when an object is inserted into document data, a method of setting the object as link data linked to the document data and a method of embedding (embedding) the object in the document data. How to set as embedded data,
There are two ways. Each of these has advantages and disadvantages.

First, when an object is set as link data, there are advantages that the size of the document data itself can be suppressed, and that the object data can be shared among a plurality of document data. However, on the contrary, there is a disadvantage that the portability of the document data is reduced. That is, even if only the document data is stored in another environment, if there is no linked object, the reproducibility of the document data is reduced.

On the other hand, when an object is set as embedded data, there are disadvantages such as an increase in the size of the document data and the inability to share the object. However, there is an advantage in that the portability of the document data is improved. .

Based on the outline shown in FIG. 6, the process of converting embedded data into link data in this embodiment will be described with reference to the flowchart of FIG. 7 and the process of converting link data into embedded data. This will be described in detail below with reference to the flowchart of FIG. The procedures in both flowcharts are realized by the CPU 2 executing the program stored in the PMEM 3.

First, FIG. 7 shows a flowchart of an example of internal processing when converting embedded data into link data.

This flowchart starts when the operator specifies the attribute of the link data to be generated from the input device such as the keyboard 9 and the mouse 10 and instructs to convert the embedded data into the link data. Is done.

In step S601, the object attribute "Atr1" (for example, JPEG format image data) of the embedded data instructed to be converted embedded in the document data is obtained. Next, step S602
Then, the object attribute "Atr2" (for example, GIF image data) of the link data to be generated is acquired. Next, in step S603, an initial value "0" is set to a counter "i" for performing a loop process for selecting an object conversion filter required for conversion. Next, in step S604, it is determined whether the value of the counter "i" is smaller than "n". Here, “n” is the number of object conversion filters stored in PMEM3. In this step S604, "
If it is determined that "i" is smaller than "n", the flow branches to step S605; otherwise, the flow branches to step S607, and the corresponding loop After the error message is displayed assuming that the object filter does not exist, the processing moves to the end processing.

In step S605, the object filter (i) sets the attribute "Atr1" of the input data to "Atr1".
Then, it is determined whether or not the filter corresponds to “Atr2” which is the attribute of the output data. This step S60
In step 5, if it is determined that the object filter (i) is the corresponding filter, the flow branches to step S608; otherwise, the flow proceeds to step S6.
The process branches to 06 to continue a loop process for selecting a corresponding object conversion filter. This step S
In 606, the counter in this loop processing is incremented, and the process returns to the determination processing in step S604.

Step S608 and subsequent steps relate to object conversion processing when it is determined that a corresponding object filter exists.

In step S608, the conversion source object data in the document data is obtained from the real object data storage area 410. In the case of the present embodiment, this object data is embedded data. In step S609, the obtained embedded data is passed to the object conversion filter to newly generate an object data file storing the object data in the desired data format (for example, from the JPEG format image data to the GIF format image data). Etc. file).

In step S610, step S609
The link information is generated so that the object data file obtained in (1) can be referred to from the document data. In step S611, the link information generated in step S610 is written in the real object data storage area 410 in which the conversion source embedded data has been set. In step S612, the related management information is updated so as to be consistent with the contents of the storage area 410 of the real object data updated in step S611, and the process proceeds to end processing.

Next, FIG. 8 shows a flowchart of an example of internal processing when converting link data into embedded data.

In this flowchart, the operator specifies an attribute of embedded data to be generated from an input device such as the keyboard 9 and the mouse 10 and instructs to convert link data into embedded data.
Be started.

First, in step S701, link information stored in the real object data storage area 410 is obtained, and an object data file linked to the document data is obtained. Next, in step S702, the object attribute "Atr1" of the link data stored in the object data file is obtained. Next, in step S703, the object attribute “Atr2” of the embedded data to be generated is acquired. Next, step S7
At 04, a counter "i" for performing a loop process for selecting an object conversion filter required for conversion.
To the initial value "0". Next, in step S705,
It is determined whether the value of the counter “i” is smaller than “n”. In this step S705, if it is determined that “i” is smaller than “n”, the flow branches to step S706; otherwise, it is determined in step S7.
The flow branches to 08, in the above loop, assuming that the corresponding object filter does not exist, an error message is displayed, and the flow proceeds to end processing.

In step S706, the object filter (i) sets the attribute of the input data to "Atr1".
Then, it is determined whether or not the filter corresponds to “Atr2” which is the attribute of the output data. This step S70
In step S6, if it is determined that the object filter (i) is the corresponding filter, the process branches to step S709. If it is not, the process proceeds to step S7.
The process branches to 07 to continue the loop processing for selecting the corresponding object conversion filter. This step S
In 707, the counter in this loop processing is incremented, and the flow shifts to the determination processing in step S705 again.

Step S709 and subsequent steps are steps relating to object conversion processing when it is determined that a corresponding object filter exists.

In step S709, the link data stored in the obtained object data file is passed to a filter to generate object data in a desired data format. In step S710, in order to embed (embed) the object data generated in step S709 in the document data, the generated object data is written to the real object data storage area 410. In step S711, the related management information is updated so as to be consistent with the contents of the real object data storage area 410 updated in step S710, and the process proceeds to end processing.

The term "document" in the present invention is not limited to simple text data, but is a general term for documents including tables, figures, images and the like. In addition, if the function according to the present invention is executed, a single device, a system including a plurality of devices,
It goes without saying that the present invention is applied to a system in which processing is performed between terminals via a network such as an AN.
