Description

Description: TECHNICAL FIELD The present invention relates to a pattern output method in an apparatus capable of registering various forms of external character patterns created by using external character pattern creating means.

[Prior Art] Conventionally, a device for outputting a halftone pattern has a document memory 1 and a graphic memory 2 separately as shown in FIG. The document memory 1 is an area for storing characters, and holds characters in the form of character codes such as JISC6226. When a character is printed by a printer or the like, a character font corresponding to each character code is taken out by the character generator 4, a dot image for one line or one page is created in the print buffer 5, and then output to the printer 6. .

On the other hand, the graphic memory 2 is an area for holding a dot image pattern. When performing halftone printing, a halftone font F having a fixed size (usually the same size as a character pattern) built in a character generator or a program (pattern storage means) is designated on the graphic memory 2. The range was extended to the specified range, this was superposed on the character pattern on the print buffer 5, and the superposed pattern was output to the printer 6.

[Problems to be Solved by the Invention] However, in the above-described conventional apparatus, the halftone pattern is fixed depending on the pattern stored in the pattern storage means, and the halftone pattern of any pattern is printed. There was a problem that it could not be output.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above problems, and pattern output in an apparatus capable of registering various forms of external character patterns created by using the external character pattern creating means. In order to make it possible to distinguish the created external character patterns of various forms from other external character patterns as a one-character mesh pattern, both the external character pattern as the mesh pattern and its identification information are stored in a memory. In order to output the specified halftone pattern, the length of the area for outputting the specified halftone pattern is derived from the number of characters and the character pitch existing in the specified area, and the specified halftone pattern is output. An external character pattern as a shaded pattern in the memory corresponding to the identified information of the shaded pattern is divided by the derived length. It is characterized by outputting a continuous halftone pattern by stitching together.

[Operation] In the above configuration, in order to output the specified halftone pattern, the length of the area for outputting the specified halftone pattern is derived from the number of characters existing in the specified area and the character pitch, The external character pattern as a halftone dot pattern in the memory corresponding to the specified halftone dot pattern identification information is connected by the derived length to output a continuous halftone dot pattern.

[Examples] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows the overall configuration of the present invention, in which a meshed external character pattern is created by the external character pattern creating means and a document is input by the document inputting means. The external character code input means specifies a shaded area and a shaded external character pattern in the input document. When the shaded external character code identifying means identifies the shaded external character code in the document, the halftone printing processing is performed on the area in the document designated by the halftone printing processing means by the designated halftone external character pattern.

FIG. 3 shows the configuration of an embodiment of the present invention. In the figure,
The CPU is a microprocessor that performs arithmetic operations, logical judgments, etc., and transfers control signals and various data to each unit described later. The ROM is a read-only memory, and stores a program of control procedures and fixed data as described later in operation. KB is a keyboard for inputting external character patterns, inputting document data, inputting print start commands, and the like. CRT is a display device such as a cathode ray tube display,
It displays patterns when creating external characters and displays input documents. DISK is an auxiliary storage device, and is used to store the input document and the created external character pattern.
The PRT is a printer and prints the input document. R
AM is a random access memory, and is used as a temporary storage SB for an input document, a work area WB for creating external characters, and a print buffer PB for storing a dot image to be output to the printer PRT. CGROM is a character generator that stores character fonts. CB is a control bus, AB is an address bus, and DB is a data bus. Control signals, address signals, and data are transferred via these buses, respectively.

Here, in this embodiment, the external character code is divided into two, that is, a normal external character and a shaded external character so that there is no common part. That is, for example, the external character code = 1 to 376: normal external character external character code = 501 to 594: shaded external character, and each external character font is created.

Next, with reference to FIG. 4, the operation in the present embodiment configured as described above will be described. Since the method of inputting a document and the method of inputting an external character pattern are well known, the description thereof will be omitted. First, as shown in FIG. 4 (A), when a document is input, a desired code C of the shaded external character codes created on both sides of a character string to be shaded is inserted. However, the left and right must have the same code. In this way, the range to be shaded is defined, and the shaded external character pattern is specified.

Next, at the time of printing, the shaded length n at the time of printing is calculated from the number of characters and the character pitch existing in the area surrounded by the shaded external characters (see FIG. 4 (B)).

Next, for the calculated shaded length n, the character font CG
The font is called from the ROM, the shaded font F is spliced, and the shaded pattern is created in the print buffer (4th
(See Figure (C)). Here, when the fractional part Δn appears in the shaded area only by splicing the specified shaded fonts F, from among the shaded external character patterns created the shaded font pattern corresponding to the length. Pick out,
The fractional part Δn is continued.

Thereafter, as shown in FIG. 4 (D), the shaded external character font and the character font are superposed on the print buffer. The contents of the print buffer thus obtained are output by a printer to realize halftone printing.

In the above-described embodiment, the character portion and the halftone dot pattern may be printed on separate lines.

[Effect] As described above, according to the present invention, in order to output the designated halftone pattern, the number of characters existing in the designated area and the character pitch of the designated area Derivation of the length, the external character pattern as a halftone pattern in the memory corresponding to the identification information of the specified halftone pattern, by connecting the derived length, by outputting a continuous halftone pattern, ROM
It is possible to output a high-quality shaded pattern of any form other than the fixed shaded pattern stored in the pattern storage means including the above.
