Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a document processing device that inputs, edits, and outputs sentence meaning, graphic data, etc.
), the document processing apparatus is capable of outputting to a plurality of output devices with different resolutions.

[Conventional technology]

In recent years, with the development of computer-based document processing technology,
Document processing systems have appeared that can edit and output different types of information such as text, 9 figures, 1 image, 2 tables, graphs, etc. on the same page. In such document processing systems, font data, typesetting logic, image memory, etc. are stored within the system, and documents can be edited independently, and furthermore, edited documents can be printed out using a page printer. . Such a DTP (desk top publishing) system equipped with a document editing system includes a workstation with an MPU, a page printer capable of outputting images stored in memory, a CRT for input/editing, a keyboard, It consisted of a mouse, etc. When designing such a document editing system, the resolution of the page printer is first determined, and the size of the page memory within the workstation is also determined according to this resolution. Furthermore, pattern data such as font data and hatching patterns are also adapted to the resolution of this page printer. Therefore, it has been impossible to output to a pressure device other than a page printer in a document editing system, especially when an output device with a different resolution is used. However, in recent years, in order to handle various output formats such as higher resolution output and film output, output from workstations to page printers has become independent of output devices such as post-crypto (device independent pen). Document processing systems using page description language (hereinafter referred to as PDL) have become commonplace. In such a system, an output device such as a printer is equipped with a page memory and font data, and can develop an output image in its own page memory according to a PDL description received from a workstation or the like. In this case, the workstation side does not need to take into consideration the performance specific to the output device, such as the resolution of the output device. That is, no matter what output device is connected, if it is the same PDL-compatible output device, it is sufficient to transmit the PDL description language. This allows the user to configure the system by selecting a necessary output device from among PDL compatible output devices.

[Problem to be solved by the invention]

However, the document processing system using PDL has the following problems when outputting external characters to an output device for display/printing. In general, external characters are character patterns designed and registered by the user as needed, in addition to the standard character patterns provided by the system, and these include free character code numbers (external character codes). Assigned. When outputting such a custom character using PDL, first a bit image of the custom character is written, a character code corresponding to this bit image is attached, and the character code is registered in the 8 card device. An example of a custom character pattern is shown in FIG. Figure 3 (A) is 16
This figure shows a custom character pattern of X16 dots, and the character code of this custom character is "2C21H" (H indicates a hexadecimal number). FIG. 3B shows a state in which this external character pattern is developed in a certain area and developed using an output device with a resolution of 400 dpi. On the other hand, FIG. 4 shows a case where the output devices have different resolutions. Figure 4 (A) shows the same 400 dpi external character pattern as Figure 3 (A), Figure 4 (B) shows the output pattern at 800 dpi, and Figure 4 (C) shows the output pattern at 200 dpi. show. When the resolution of the output device is high as shown in Fig. 4 (B), for example 800 dpi, the output device uses some logic to enlarge the external character pattern by 2 times to 1 m.
The patterns are developed after making sure that the designs of the patterns filling the area of m×1 mm are similar. Conversely, when the resolution of the output device is low as shown in FIG. 4(C), for example at 200 dpi, the external character pattern is reduced to 172 and output. Here, as shown in Fig. 3, if the resolution of the external character pattern and the resolution of the output device are the same, output with the expected image quality can be obtained, but as shown in Fig. 4,
When outputting to an output device with a resolution different from that of the image data, the image quality may not necessarily be satisfactory. This means that when outputting to a high-resolution PDL-compatible 8-capable device, text data, vector data, etc. can be output at high resolution by the output device performing image development according to its own resolution. On the other hand, a custom character pattern is a character pattern that is not included in the font data of the output device, so the same effect cannot be expected. In other words, as shown in Figure 4 (B), even if the original external character pattern is enlarged twice to create a pattern that matches the resolution of the output device, this enlargement is simple interpolation; This is because the essential amount of information of the created custom character pattern remains at 400 dpi. Furthermore, as shown in FIG. 4C, in cases where the external character pattern is reduced, the character pattern is often damaged because the pattern is reduced by mechanical thinning. As described above, conventionally, when a basic external character pattern is converted in accordance with the resolution of an output device, an image output that takes advantage of the resolution of the output device cannot be obtained. Also, Figure 4 (C
), when the external character pattern is reduced, the reduction of the pattern due to mechanical thinning often causes the pattern to be damaged.The present invention has been made in view of the above conventional example. By registering custom character patterns designed for each resolution and outputting the corresponding custom character patterns according to the resolution of the output unit, output parts with various resolutions can output custom character patterns as expected. The object of the present invention is to provide a document processing device that can obtain output.

[Means to solve problems] In order to achieve the above object, the document processing device of the present invention has the following configuration. That is, A document processing device that inputs, edits, and outputs text, graphic data, etc., and includes a plurality of output means having different resolutions for inputting, displaying, and outputting document data, and a device corresponding to the resolution of the plurality of output means. a storage means for storing a plurality of external character patterns having different resolutions; a selection means for selecting one of the plurality of output means; and registration means for selecting a corresponding pattern from a plurality of external character patterns and registering the selected pattern in the selected output means. [Effect]

In the above configuration, document data can be displayed/outputted by a plurality of output means having different resolutions and inputting document data and displaying/outputting it. A plurality of external character patterns having a resolution corresponding to the resolution of these output means are stored, and a corresponding pattern is selected from the stored plurality of external character patterns according to the output means to be used and registered in the output means. . Thereby, the output means can develop document data into image data using a custom character pattern according to the resolution and output the image data.

The printer is sold under a product name such as "E.C.)". The format of data input to this printer 119 is shown in FIG. Of course, an actual system can accept more commands, but for the sake of explanation, the data format shown in FIG. 5 will be used here. The case where the sample document data shown in FIG. 6 is created according to the data format shown in FIG. 5 will be described. FIG. 7 is a diagram showing an example of output data created in this manner. The output data shown in the description language of FIG. 7 will be explained. 7

Here, as shown in FIG. 6, the coordinate system of the document is treated as 3000 dots horizontally and 4000 dots high, and the paper size is A4 size. 72 indicates a custom character registration (gaiji) command. Here, the external character code number is “2C21H” as mentioned above.
”, a 32x32 dot pattern ('000001
10...0001) is registered. 73 is a character output command (putcher) that outputs 23 characters from character position (200, 800). Those character code strings are the following character code strings, "2433""2433"'"
2447"..."2C21"... This character string corresponds to "Here, line breaks are indicated by..." in FIG. And the end command (end)
74, when the data reception is completed, printing is executed. As a result, the sample document shown in FIG. 6, which includes only text data, is printed by the printer 119. Note that in order to create output data to the printer 119 shown in FIG. 7 according to the description language shown in FIG. 5, a conversion table stored in the program memory 103 or the hard disk 114, for example, may be used. The conversion and table referred to here are, for example, converting the document data shown in FIG. 8 into the r character output command shown in FIG.
This is a table that converts to . Note that the bit image of the private character pattern written by the gaiji instruction 72 in FIG. 7 is created from the private character pattern stored in the hard disk 114. An example of this external character data format is shown in FIG. At the beginning of this external character data, r resolution type number NJ191
There is. This number (N) is arbitrary and is set to the number of resolution types of output devices that may be connected to this system. Here, the resolution of the printer 106 is set to 400d.
pi, the resolution of the printer 119 is 800 dpi, and assuming that these two are connected, this number of types (N)
becomes “2”. At this time, the resolution data is roughly divided into two parts 92 and 93, one being data 92 for 400 dpi (for printer 106) and the other being data 93 for 800 dpi (for printer 119). Details of each of 92 and 93 are shown on the right side of FIG. "Resolution type number 81 includes data 92 for 400 dpi.
In this case, "400" is set, and in the case of data 93 for 800 dpi, "800" is set. In the dot matrix size 182, 400 dpi data 92 is set to 16, and 800 dpi data 93 is set to 32. these are,
This indicates that bit image data designed in a matrix of 16×16° and 32×32 is registered. In this system, the number of characters that can be registered as external characters is 9, and the characters are numbered sequentially from 2C21 (H) to 2029 (H). It is assumed that each resolution data includes nine bit image data for each dot matrix size. When outputting this external character, which data to use is selected according to the resolution of the 8-digit device. For example, when applying pressure to the printer 119, since the printer 119's resolution is 800 dpi, which is registered in the system in advance, the "resolution type J81 is "800"" is displayed when outputting.
Search for data that is , and output the external character pattern of that data. Figure 10 shows the external character code "2C2LH" used in Figure 6.
FIG. 3 is a diagram showing patterns registered in . Figure 10 (
A) is the external character pattern for 400 dpi, Figure 10 (B)
is a custom character pattern created for 800 dpi. FIG. 10(C) shows a bit pattern obtained by simply doubling the 400 dpi custom character pattern shown in FIG. 10(A) to 800 dpi when no 800 dpi custom character pattern exists. In this way, the external character pattern in FIG. 10(B) is a smoother character pattern than the pattern in FIG. 10(C). In the output data of FIG. 7, the gaiji instruction 72 on the second line
Since the data for 800 dpi in FIG. 10(B) is specified, the external character pattern printed by the printer 119 has smoother diagonal lines than the pattern obtained by the 400 dpi printer 106. Similarly, if other resolutions are connected to the output device, for example, 120Odpi, 2Odpi, etc.
It is sufficient to additionally register a custom character pattern for 400 dpi or the like in a data format as shown in FIG. To create these data, a dedicated editor or the like may be provided in the system, or even if the design is created using another method, there is no problem as long as it is registered in the format shown in FIG. Next, the operation when outputting document data will be explained with reference to the flowchart in FIG. First, the user of this document processing system
By pointing to the icon displayed in 12 using the mouse 109, it is determined whether to use the printer 106 or the printer 119 (step Sl).
. Here, when using the printer 119, you can specify the resolution of the printer 119 (Yes). If the printer 106 is selected in step S1, the process advances to step S5, and the IMEM 104 supports document data. The bitmap data is developed and outputted to the printer 106 in step S6. On the other hand, if the printer 119 is selected in step S1, the process advances to step S2 and waits for the input of the resolution of the printer 119.The printer 119 operates as described above. Any 8-capable device compatible with PDL mentioned here can be used, and it can be connected via the communication port 117, or even if it is not connected, as long as it can receive output data via the floppy disk 115 or the like. OK. Here, when outputting to the printer 119, the operator determines what kind of output device corresponds to the printer 119 and inputs its resolution.Next, in step S3, the document shown in FIG. The data is converted into the output data of the PDL description shown in Fig. 7 as described above.The external character pattern registration command at this time is in step S2.
The external character pattern data shown in FIG. 9 is read out from the external character pattern data stored in the hard disk 114 and having the resolution specified by . This allows the PD to use the pattern data of the external character data according to the resolution of the specified printer 119.
L is described. Next, in step S4, the output data of the PDL description of FIG. 7 created in step S3 is output to the printer 119. Here, it is assumed that the printer 119 can receive the data shown in FIG. 7 in ASCII code. Note that this output data is
The data may be sent by communication using a communication interface such as a 3232C or Centro interface. Thereby, the printer 119 can perform printout as shown in FIG. 6, for example, using a custom character pattern corresponding to the resolution. As described above, according to this embodiment, external character patterns are individually designed for each resolution of a device that can be an output target. Then, when using PDLa, a custom character pattern with a corresponding resolution is selected to enable PDL description. As a result, no matter what resolution a PDL-compatible output device is connected to this system, an output result using an appropriate external character pattern can be obtained.

【Effect of the invention】

As explained above, according to the present invention, external character patterns individually designed for each resolution are registered, and by outputting the corresponding external character patterns according to the resolution of the output unit, output units having various resolutions This has the effect of obtaining the expected external character pattern output.
