CONSTITUTION:For example, nine kinds of hatching patterns are prepared, and numbers 1 to 9 are attached on them, and it is assumed that every nine pieces of bit image data are provided at each data for resolution at every dot matrix size. A (resolution specification number H) 1001 is attached on the forefront of a data format printed by the hatching pattern, and the number of specifications of the resolution of an output device is set. In other words, document data can be displayed and outputted by plural output means provided with different kinds of resolution and which input the document data and display and output them. Therefore, plural hatching patterns are stored, and a corresponding pattern is selected corresponding to the output means in use, and it is registered on the output means. Thereby, the output means can output the document data by using the hatching pattern in accordance with the resolution.

Description

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

The present invention relates to a document processing device that inputs, edits and outputs text, 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 emerged that can edit and output different types of information, such as text, figures, five images, 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, if an output device other than a page printer is used in a document editing system, especially an output device with a different resolution, it is impossible to output to that device. However, in recent years, it has become possible to handle a variety of output formats such as higher resolution output and film output, so output from workstations to page printers has become independent of output devices such as postcrypt (device independent pen). Document processing systems using page description language (hereinafter referred to as PDL) have become commonplace. In such a system, eight devices such as printers are equipped with a page memory and font data, and can develop an output image in their 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 the PDL has the following problems when outputting a figure having a "hatched pattern surface" to an output device for display/printing. An example of a hatching pattern is shown in FIG. Figure 3 (A)
is a diagram showing a basic hatching pattern of 16×16 dots. FIG. 3(B) shows a state in which this basic pattern is continuously developed in a certain area and the area is "filled in" at 400 dpi. Next, a case will be described in which such a figure is described using PDL. First, the bit image of the basic pattern is described, and then the size of the area that one basic pattern occupies when output is described. In the case of Fig. 3, the basic pattern shown in Fig. 3(A) is designed, and this basic pattern is l mmX per pattern.
1 aun area (resolution at this time is 4
00dpi). In this case, as shown in Fig. 3(B), when the resolution of the 8 devices is 400 dpi,
It is only necessary to expand the bit image of the basic pattern as it is. On the other hand, FIG. 4 shows a case where the output devices have different resolutions. FIG. 4(A) shows the same basic pattern as FIG. 3(A), FIG. 4(B) shows an output cover turn at 800 dpi, and FIG. 4(C) shows an 8 cover turn at 200 dpi. 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 basic 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. On the other hand, when the resolution of the a-cubic device is low as shown in FIG. 4(C), for example at 200 dpi, the basic pattern is reduced to 172 pixels and output. Here, as shown in FIG. 3, if the resolution of the basic 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.
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 is because when outputting to a high-resolution PDL-compatible output device, text data, vector data, etc. are output at high resolution by the output device, which develops images according to its own resolution. This is because similar effects cannot be expected. That is, Fig. 4 (
As shown in B), even if the basic pattern is enlarged twice and the resolution of the output device is matched, this enlargement is a simple interpolation, and the essential information content of this hatching pattern remains at 400 dpi. It is. This becomes clearer with reference to FIG. FIG. 11(A) is the basic pattern shown in FIG. 3(A) and FIG. 4(A). On the other hand, Fig. 11(B) shows 3
This is a hatching pattern corresponding to 800 dpi expressed with 2×32 dots. Figure 11(C) (same as Figure 4(B)) is the same hatching pattern (32x32 dots) compatible with <800 dpi;
Since it is an 800 dpi pattern created by interpolation processing based on the basic pattern shown in A), it is a rougher pattern than the pattern in FIG. 11(B). Further, for example, in FIG. 5, it is assumed that the basic pattern shown in FIG. 5(A) expresses "gray" of a certain density. FIG. 5(B) is a diagram obtained by enlarging the basic pattern of FIG. 5(A) twice and converting it into an 800 dpi pattern. On the other hand, FIG. 5(C) shows a gray pattern created in advance as pattern data of 800 d'pi. As is clear from the figure, the pattern shown in FIG. 5(C) can obtain a finer gray color by taking advantage of the higher resolution than the pattern shown in FIG. 5(B). As described above, conventionally, when a basic hatching pattern is converted in accordance with the resolution of an output device, an image a-color that takes advantage of the resolution of the output device cannot be obtained. Also the fourth
When the basic pattern is reduced as shown in Figure (C), the pattern is often damaged due to the pattern reduction due to mechanical thinning. The present invention has been made in view of the above-mentioned conventional example, and by registering hatching patterns individually designed for each resolution and outputting the corresponding hatching patterns according to the resolution of the output section, various types of hatching patterns can be created. It is an object of the present invention to provide a document processing device that can obtain hatching pattern output as expected using an output unit having a high resolution.

[Means to solve the problem]

In order to achieve the above object, the document processing device of the present invention has the following configuration. That is, it is a document processing device that inputs, edits, and outputs text and graphic data, and inputs, displays, and outputs document data.
a plurality of output means having different resolutions, a storage means for storing a plurality of hatching patterns having resolutions corresponding to the resolutions of the plurality of output means, and a plurality of hatching patterns stored in the storage means according to the output means to be used. and registration means for selecting a corresponding pattern from the hatching patterns and registering it in the 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 hatching patterns having a resolution corresponding to the resolution of these output means are stored, and a corresponding pattern is selected from the plurality of stored hatching patterns according to the output means to be used. register. Thereby, the output means can output document data using a hatching pattern according to the resolution.

In the system shown in the figure, when printing is performed using the printer 106, font data, graphic data, image data, etc. are developed as a bit image in the image memory 104, and then this image is Data in memory 104 is output to printer 106. This printer 106 outputs a black or white bit image on the recording paper according to the data "l" and "0" output from the image memory 104. Next, a case where the same document data is output to the printer 119 will be described. Here, the printer 119 is compatible with a page description language such as PostScript, and is, for example, rVari.
typer J, rcompugraphicJ
, rLin. typeJ, r PC-PR602PS (N
The printer is sold under a product name such as "E.C.)". The format of data input to this printer 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. 6 will be used here. A case where the printer 119 outputs the sample document data shown in FIG. 7 using the data format shown in FIG. 6 will be described. In this case, the data shown in FIG. 8 may be transmitted. In FIG. 8, 81 indicates a size (sheet) instruction. Here, the width is 3000 dots, the height is 400 dots, and the paper size is A4.
It shows the size. Reference numeral 82 indicates a hatching pattern registration (hatch) command. Here, a 32x32 dot pattern is displayed as the hatching pattern number "1" with a size of lmm.
This indicates that the image is registered at x1mm (800dpi). 83 is a rectangle drawing (rect) command, and the starting point (90
0,2000) to the end point (2500,3200),
A solid line (line type=O) with a line width of 4 mm indicates that a hatching pattern with hatching pattern number "1" is drawn. Note that printing is executed when data reception is completed according to the end command (e n d). FIG. 9 is a diagram showing the format of document data that this document processing system originally has. This example shows a format example of a sample document in which the document data and image data shown in FIG. 7 do not exist, and only one piece of graphic data exists. In order to print this document data on the printer 119, it is converted into output data to the printer 119 according to the description language shown in FIG. This conversion process includes, for example, the program memory 103
Alternatively, a conversion table stored in the hard disk 114 may be used. The conversion table referred to here is, for example, for converting "graphic data type = rectangle" shown in Figure 9 into a page description language such as "rectangle drawing command = rect...j" shown in Figure 6. When the output data shown in Fig. 8 is created in this way and sent to the printer 119, the document data shown in Fig. 7 is printed. The bit image of the hatching pattern is printed using the hatching pattern stored in the hard disk 114. An example of this data format is shown in FIG. 10. At the beginning of this data, r resolution type number NJ 1001
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.
Assuming that the resolution of pi and printer 119 is 800 dpi and these two are connected, the number of types (N) is "2". At this time, the resolution data is roughly divided into two parts 1002 and 1003, one is data 1002 for 400 dpi (for printer 106), and the other is data 1002 for 80 dpi.
The data 1003 is for 0 dpi (for the printer 119). Details of each of 1002 and 1003 are shown on the right side of FIG. The number of resolution types is 131, data 1 for 400 dpi
In the case of 002, "400" is set and 800dp
In the case of data 1003 for i, "800" is set. 400dp for r dot matrix size J132
"16" is set in the data 1002 for i, and 80
“32” is set in the data 1003 for 0 dpi. These indicate that bit image data designed in a 16×16.32×32 matrix is registered. In this system, there are nine types of hatching patterns,
Assume that they are numbered from 1 to 9. It is assumed that each resolution data has nine bit image data for each dot matrix size. The area of the graphic data is specified by this number, and which graphic data to use is selected depending on the output device. For example, when outputting to the printer 119, since the printer 119 is registered in advance as 800 dpi in the system, when outputting, r resolution type J1
Search for data where 31 is "800" and press the hatching pattern for that data. Figure 11 shows eighting pattern number 1 used in Figure 7.
FIG. 3 is a diagram showing patterns registered in the number. Figure 11 (A) is the hatching pattern for 400dpi, the first
Figure 1 (B) is a hatching pattern for 800 dpi. As mentioned above, FIG. 11(C) is a bit pattern obtained by simply doubling the hatching pattern for 400 dpi to 800 dpi. In this way, Figure 11 (B
) is a smoother hatching pattern than the pattern in FIG. 11(C). In the output data of FIG. 8, the hatch instruction 82 on the second line
Since the data for 800 dpi shown in FIG. 11(B) is specified, the printer 119 can output a diagonal line that is smoother than the output obtained by the 400 dpi printer 106. Similarly, if other resolutions are connected to the output device, for example 120Odp i,
240 Odpi etc. may be additionally registered 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. 10. Next, the operation at the time of output will be explained with reference to the flowchart of FIG. First, the user of this document processing system selects the printer 10 by pointing the icon displayed on the CRT display section 112 using the mouse 109.
6 or the printer 119 is determined (step S1). Here, when using the printer 119, it is possible to specify the resolution of the printer 119. If the printer 106 is selected in step S1, the process advances to step S5, and the resolution corresponding to the document data is set in the IMEM 104. 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 input of the resolution of the printer 119.The printer 119 operates as described above. Any output device that is compatible with the PDL mentioned above may be used, and it may be connected via the communication port 117, or even if it is not connected, it may receive output data via the floppy disk 115 or the like. Here, when outputting to the printer 119, the operator determines what kind of pressure device corresponds to the printer 119 and inputs its resolution.Next, in step S3, the document data shown in FIG. As mentioned above, the data is converted into the 8-bit data of the PDL description shown in Fig. 8.The hatching pattern registration command at this time is executed on the hard disk 1 with the resolution specified in step S2.
The data for the specified resolution is read out from the hatching pattern data shown in FIG. 10 stored in 14 and described. Next, in step S4, the output data of the PDL description of FIG. 8 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. 8 in ASCII code. Note that this output data can be transferred to the R52 even if it is sent via a floppy disk as described above.
It may also be sent by communication using a communication interface, such as a 32C or Centro interface. As a result, the printer 119 prints out, for example, as shown in FIG. 7, using an appropriate hatching pattern at the resolution of the printer 119. As explained above, according to this embodiment, a hatching pattern designed individually is prepared for each resolution of a device that can be an output target, and when outputting PDL, the hatching pattern of the corresponding resolution is selected and the PDL is output. Make it possible to describe. As a result, no matter what resolution PDL-compatible output device is connected to this system,
Output results using appropriate hatching patterns can be obtained.

【Effect of the invention】

As explained above, according to the present invention, hatching patterns individually designed for each resolution are registered,
By outputting a corresponding hatching pattern according to the resolution of the output section, it is possible to obtain expected hatching pattern outputs from output sections having various resolutions.
