Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mixed mode document printing method for printing a so-called mixed mode document in which text information and image information are mixed, and in particular relates to a mixed mode document printing method that prints a so-called mixed mode document in which text information and image information are mixed. The present invention relates to a document printing device that prints a mixed-mode document received via .

[Conventional technology]

In recent years, with the rapid spread of office automation (OA), editing, displaying, and printing of so-called mixed-mode documents, in which text information and image information coexist, has become popular. Furthermore, so-called mixed-mode communication, in which mixed-mode documents are transmitted and received via communication lines, has already been devised. A protocol (communication protocol) for mixed-mode document exchange has already been recommended by the CCITT (International Telegraph and Telephone Consultative Committee), and domestically, the Ministry of Posts and Telecommunications has announced the "Recommended Mixed-mode Communication Method" ( Ministry of Posts and Telecommunications Notification No. 198 of 1985).

A mixed-mode document exchanged in mixed-mode communication has the following structure.

That is, the entire document has one or more pages, and each page can have one or more rectangular areas (hereinafter referred to as blocks) having sides parallel to each side of the page. One block contains either text information or image information. Note that there may be pages that do not have any blocks, but in that case, the page itself can be considered as one block. If the page itself is a block, the information contained within the page is naturally either text information or image information. Note that hereinafter, the character information or image information included in a block will be collectively referred to as text.

The printing position of the text included in the block is determined by the layout information paired with the text itself. Layout information includes the position and size of a page and the position and size of a block. These are based on a rectangular coordinate system with the origin at the upper left corner of the physical paper, the horizontal direction as the X axis (the right direction is the positive direction), and the vertical direction as the Y axis (the bottom direction is the positive direction). It is defined as. The position of the block is
This is the upper left corner point of the block, determined by its position relative to the origin of the Cartesian coordinate system described above. The size of a block is a set of dimensions of the block in the X$d1 direction and the Y-axis direction. The position and size determine where on the page the text contained in the block should be printed. Note that the position of the page itself coincides with the origin of the above-mentioned orthogonal coordinate system.

When the text included in the block is character information, the position at which each character is printed is determined by the printing position of the first character attached to the document, one character advancing direction, one line advancing direction, one character interval, one line interval.

FIG. 6(a) is a schematic diagram illustrating the positional relationship between pages, blocks, and character data within the blocks. Reference numeral 21 denotes a page, which is configured with horizontal PW and vertical PH.

? 2 is a block, horizontally B from the upper left corner point of page 21
It is located at X, vertical BY, and has a size of 41 B W and vertical BH. 23 is a set of characters, block 22
included in.

Note that the character set 23 is shown as being composed of character blocks 23a to 23d. character block 23
The first character of a is horizontally CX from the upper left corner point of block 22,
It is located in vertical CY. Here, PW, PH, BX, B
Y, BW, BH, CX, and CY are positive integers.

, FIG. 6(b) shows block 2 shown in FIG. 6(a).
FIG. 6 is a schematic diagram illustrating a state in which a set of characters 23 partially protrudes from FIG. 2, and the same parts as in FIG. Note that the shaded area in the figure is the part where the set of characters 23 partially protrudes from the block 22.

The size of characters when editing or displaying a document depends on the characteristics of the device. Therefore, in a certain device, a document is created in which all the characters constituting the character information are completely included in the area where the character information should be printed,
Even if this is sent to another device, if the receiving device prints it, it may extend beyond the printing area. In this case, the point to be considered is that part of the character box (set of characters 23) is inside the block 22 and the other part is outside the block 22, that is, as shown in FIG. 6(b).
This is the printing of the characters shown in the shaded area.

Conventionally, in such cases, it has been common practice to discard characters that partially protrude from the printing area without printing them.

[Problem that the invention seeks to solve]

However, according to the conventional method, block 22
Since the inner portions are also not printed, there is a problem in that information intended by the sender is more likely to be missing. Also, among the characters that are partially protruding, block 22
A method of printing only the part inside the block 22 can be considered, but in that case, the process of separating the part inside the block 22 and the part outside the block 22, for example, by developing the font of the character and printing it outside the block 22, is possible. Processing such as discarding a certain portion must be performed, resulting in a problem that the processing speed is significantly reduced.

This invention was made to solve the above problems, and the page size of input mixed document data,
By comparing the block size and the printable area of the printing means and determining the printability of the character blocks overflowing from each block based on the calculated boundary conditions, the character blocks overflowing from each block within the printable area are determined. An object of the present invention is to obtain a document printing device that can also print.

Please judge whether the size is within the printable area 166)
, If No, it is determined that printing is not possible and a predetermined abnormality process is executed 7), If YES, it is determined whether the data type in the block is character information 8), If YES, character information decoding processing is executed 9) ), return to step (3).

On the other hand, if the determination in step (8) is NO, the image information decoding process is executed (10) and the process returns to step (3).

Next, the print control operation for a mixed mode document according to the present invention will be described with reference to the flowcharts shown in FIGS. 5(a) and 5(b).

FIGS. 5(a) and 5(b) are flowcharts illustrating the print control operation procedure of the mixed mode paper meter according to the present invention. Note that (1) to (9) and (11) to (15) indicate each step.

First, the communication port! The document received from 3il16 is once taken into the RAM 13 via the communication control unit 5 and stored on the magnetic disk 4. A document stored in the 611 disk 4 is read out from the RAM 13z by an input means (not shown),
Referring to the position of the first character block 23a shown in the received document, find the coordinates of the upper left corner point of the character box 23a, and set its X coordinate value and Yi standard value to the position of the RAM 13.
11 report area X.

In addition to writing the position information of the block 22, which can be known in advance from the layout size information, ie, the position 1i\f+! f (ill Initialize to write areas bx, by, block 220 width information area bw, height information area bh into RAM 13 (1).

Next, it is determined whether the character data to be processed has ended 2), and if YES, the next character is read 3), and the read character is a control code, i.e., carriage return, line feed, backward 1 part line, 9 part line Please judge whether it is lowered or not 4).
If YES, that is, the code gives the position of the character block 23a to be printed, the position of the character block 23a is updated (9) and the process returns to step (2).

On the other hand, if the determination in step (4) is No, the positional relationship between the character and the block 22, that is, whether the character is completely included in the block 22 or partially protrudes from the block 22;
Alternatively, a print position check routine (flow chart shown in FIG. 5(b)) is executed to determine whether the print position completely protrudes outside the block 22 (5). Next, the CPU II uses the print position check routine to determine whether the judgment result information rt is "0" from the value stored at address A7 of the RAM 13 (6). If YES, it means that the character block 23a is a 22, the printer 3 prints the characters stored in the RAM 13 based on the coordinate values stored in the position information 11 areas x, y stored in the address A, A2 of the RAM 13 7)
, if No, proceed to step (8), character block 23
In order to print the next character of a, the print position is updated 8), and the X coordinate value and X coordinate value of the updated position are stored in the RAM 13, respectively.
Write in the position information areas x and y of . Return to step (2). Note that in this embodiment, each character block 238 to 2
In 3d, the width FX and height FY are eigenvalues.

If the determination in step (4) is No, that is, if it is determined that the data is character data, the flowchart shown in FIG. 5(b) starts, and the determination conditions will be explained.

For example, whether the character block 23a is completely included in the block 22 or partially protrudes from the block 22 is necessary and sufficient if the following conditions (1) to (2) are satisfied.

x＞bx−FX ・・・・・・ ■x＜bx+
bw... ■y>by-FY...
・・・・ ■y＜by＋bh ・・・・・・
■Therefore, the CPU II sequentially determines whether or not the above conditions ■ to ■ hold regarding the position of the character to be printed (11
) to (14). If all of these judgments are YES, the CPU
II writes "0" in the judgment result information area rt of the RAM 13 (15), returns to step (6), and depending on the judgment in steps (11) to (14),
If C' is also No, the CPU 11 writes "1" to the judgment result information area rt of the RAM 13 (16),
Return to step (6).

In addition, in the above embodiment, each character block 23a to 23d
Although the explanation was made for the case where the width FX and height FY of 2 are unique values, 2
This invention can also be applied when the width and height of the character box is greater than or equal to RAM 1.
