Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a character processing method and apparatus such as a word processor, and more particularly to a word processor having a wide variety of printable character sizes. 2. Description of the Related Art A conventional word processor has a configuration as shown in FIG. The character string input from the keyboard 302 is displayed on the display device 303. The user performs input and editing operations while watching the display. This display is performed as follows. That is, the CPU 301 scans the keyboard 302 to detect an input character string. CPU
301 writes the code of the detected character to be displayed on the VRAM 307. The display device 303 creates and displays a character image to be displayed by referring to the display character font 306 from the character code string developed in the VRAM 307. [0003] Printing is performed as follows. That is, a document file storing document data to be printed
The character code string to be printed is read from 308 and expanded in the print buffer 310. The printer 304 performs printing by referring to the print character font 309 according to the contents of this buffer. This conventional word processor has two types of character fonts for display and printing. This is because, while it is desired to display as many characters as possible for a limited display capacity in display, essentially different character fonts are used in printing in order to obtain as beautiful a result as possible. A 16x16 dot Gothic font is usually used as a character font for normal display, and a Mincho font with a matrix size of 24x24 dots or more is often used for printing. Japanese Patent Application Laid-Open No. 55-147776 discloses that when reading a font, the font is enlarged or reduced and displayed or printed by setting the read clock to 1/2 or 2 times. Japanese Patent Laid-Open Publication No. Sho 57-34241 discloses two types of fonts, Mincho font and Gothic font, which are displayed or printed by selecting two fonts according to the font code attached to the character code. It is shown. The function of changing the size of a print character in a conventional document processing apparatus is poor, and as shown in Japanese Patent Application Laid-Open No. 55-147776, one of the character fonts is used at the time of printing. In this method, enlarged characters are printed out by repeating dots vertically and horizontally by n dots (n is an integer).
This method is limited to when n is an integer. For example, CP that tries to expand to 1.5 times or reduce to 2/3 times the size of a standard size character
Not only is a heavy burden on the U, but the printed characters are also angular and unnatural. [0007] Japanese Patent Application Laid-Open No. 57-34241 The publication only indicates that display or printing is performed using Mincho and Gothic fonts, and does not make any new proposal for the reduced printing function. It is an object of the present invention to provide, for example, 2/3 without adding new hardware or complicated software logic.
An object of the present invention is to provide a document processing apparatus capable of printing characters having a size that is not an integer ratio with respect to a standard character size such as square characters at high speed.

Means for developing a print image of a character having a given size,
According to the print image developed in the print buffer,
And printing means for performing printing. FIG. 1 is a block diagram showing the configuration of a character processing device according to the present invention. The CPU 101 receives data input from the keyboard 102 and performs processes such as kana-kanji conversion and controls the display device 103, the printer 104, the external storage device 105, and the like. In a document input operation, the CPU 101 scans the keyboard 102 to detect a pressed key.
The character corresponding to the detected key is the first character font 10
The character font is read from 6 and expanded in the VRAM 107. The display device 103 reads out display data of the VRAM 107 and performs display. The user creates document data while editing or modifying while viewing this display. The created document data is stored in the RAM 108 or the external storage device 105. The CPU 101 also performs processing such as kana-kanji conversion and editing at the same time. When the creation of the document data is completed, the user normally enters a printing operation, but the operation at this time is as follows. That is, the CPU 101 reads out the contents of the document data stored in the external storage device 105 or the RAM 108, and reads out the first character font 10
The corresponding character font data is read from the sixth or second character font 109 and the print image is developed in the print buffer 110. The printer 104 performs printing according to the print image developed in the print buffer 110. Since the first character font 106 is used for display, it is preferable that the first character font 106 has a matrix size as small as possible. Usually 14 ~
It is enough to have 16 dots square. On the other hand, if the matrix size of the characters to be printed is not larger than a certain size, the print quality becomes poor and the characters are printed. Printing of various character sizes can be performed as follows. That is, the user wants to print in large characters, such as a title, during the document input operation,
Alternatively, specify a character string to be printed in small characters, such as a comment line. This designation is recorded in the document data together with the character code string as an attribute of the character string or as a code for modifying the character code string in the document data. At the time of printing, it is determined whether to read the character font data from the first character font 106 or the second character font 109 in accordance with the character size specified in the document data. What is necessary is just to expand the print image of the character of the size. Printer
104 performs printing according to the print image developed in the print buffer 110. Normally, a 24-pin dot matrix type is used as the printer 104. When printing a character having a matrix size smaller than 24 dots, for example, when printing a character having a font size of the first character font 106, let the 8 pins be loose. Print only with 16 pins. When printing an enlarged character, one character may be printed a plurality of times. If the matrix size of the first character font 106 and the second character font 109 is not a multiple of an integer, the conventional method of reducing or taking every two dots or arranging them in an integral multiple is provided. At the same time, the size of characters is further increased. FIG. 2 shows a printing example of the character processing apparatus according to the present invention. FIG. 2A shows an example of printing using the first character font 106, and FIG. 2B shows an example of printing using the second character font 109. In this example, the first character font 106 has a matrix size of 16 × 16 dots, and the second character font 109 has a matrix size of 24 × 24 dots. FIG. 2 (c), (d)
FIG. 3 is a diagram in which the first and second character fonts are reduced by two to four dots in total by four dots in each of the vertical and horizontal two dots. Similarly, FIGS. 2E and 2F are diagrams in which the first and second character fonts are superimposed two dots at a time in the horizontal direction and enlarged in the horizontal direction, and FIGS. 2G and 2H are vertically enlarged. It is the figure which expanded. FIG.
(I), (j) is the figure which expanded both the length and width twice. As described above, according to the present invention, the first font dot memory can also be used for displaying while the number of font dots can be printed, and the storage capacity can be reduced. In addition, there is an effect that the displayed font shape can be printed out as a font shape desired by the user.
