Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various character processing devices such as a word processor, and more particularly to an enlargement designation and display technique of input characters. 2. Description of the Related Art Conventionally, in order to enlarge a character in a word processor or the like, a quadruple size,
A method for enlarging and displaying characters at a predetermined magnification such as double-width, and specifying an enlargement size to arbitrarily enlarge the height and width to nxm times, as used in portable word processors in recent years And so on. Regarding the function to be specified in character units such as quadruple and double width, the size of enlargement is doubled, and by fixing this, display and print processing are reduced, and processing speed and machine cost are suppressed. The method has come. When the vertical and horizontal enlargement is specified to be an arbitrary enlargement size of n × m times, it is specified in units of lines, and when a print instruction is given, the designated process of n × m times is performed in a series of processes. In order to reduce the processing, all the processes are performed in the same manner. Therefore, as shown in FIG. 20, even when a character is input to a line including a character designated to an arbitrary enlarged size, the character input does not consider the size of the character after the enlargement. Since characters having the same number of characters as in a normal line can be input, characters enlarged at the time of printing may be lost beyond the paper width as shown in FIG. In addition, as shown in FIG. 22, when there are a large number of characters having two different enlargement ratios, the enlargement ratio must be specified again for each character, and then the enlargement designation must be performed. It was connected. As described above, when creating and editing a document, it is necessary to input characters while taking into account the enlarged print result, and the operability is very poor, such as re-specifying the enlargement ratio of a character having a different enlargement ratio every time. I got a point. Purpose This invention has been made in view of the above, the purpose of improving the operability of the magnification specified diversity document creation. In order to achieve the above object, the present invention provides a character processing device that includes at least an input device and a display device and that can display characters and the like input from the input device on a display device and perform editing and proofreading. A plurality of arbitrary magnification specifying means for enlarging and displaying characters and the like displayed on the display device in accordance with an instruction from the input device; enlarged character specifying means for individually specifying a target character or character string to be enlarged at the magnification; Display means for displaying on a screen at a magnification.

Key wire buffer 49, character generator (CG) 50, enlarged cutout 5
1, position correction designation unit 52, text enlargement position correction update unit 53, and display control unit 26
It consists of. The input device 1 is a keyboard for inputting various key data such as characters, key lines, cursor movement, and character enlargement as described above. The input control unit 25 determines various key data input from the input device 1 and transfers the data to each functional unit according to the determination result. When the input control unit 25 recognizes that the key data input from the input device 1 is character data, the character editing unit 40 receives the character data from the input control unit 25 and edits the character. The display line developing unit 41 sequentially extracts data from the text buffer 43 and the format format information unit 42, and determines the horizontal arrangement of one line of characters while creating text information to be displayed. The format format information section 42 stores format information related to the format and outputs the format information to the display line developing section 41. The text buffer 43 includes a normal character code, a character code at the time of enlargement designation, and
The character codes at the time of center-alignment and bottom-alignment enlargement designation are set as shown in FIGS. 8, 9 and 10, and these data are temporarily stored. The displayed text information unit 44 sets the horizontal arrangement of the characters determined by the display line developing unit 41 for one line as the size of one ordinary character as a physical line as shown in FIG. The enlarged size is calculated, and this is set as a logical line of this line, and an enlarged size table and a display information table are created and output to the display line developing unit 41. When enlargement is instructed from the input device 1, the enlargement designation control unit 45 outputs the cursor information of the cursor control unit 48 and the enlargement size of the enlargement size storage area 47 to the display line development unit 41 as a display change. The enlarged size of the enlarged size storage area 47 is also output to the text buffer 43. The enlargement size designation unit 46 receives an input of a change of the enlargement size from the input device 1,
This enlarged size data is received from the input control unit 25 and transferred to the enlarged size storage area 47, and is output to the display control unit 26 for displaying a message on the display device 2. The enlarged size storage area 47 has a plurality of (two in this embodiment) enlarged size areas, receives enlarged size designation data from the enlarged size designation section 46, and stores the enlarged size in each enlarged size storage area. At the same time, the enlargement size is output to the enlargement designation control unit 45. The cursor control unit 48 inputs cursor information from the input control unit 25 and outputs the cursor information to the character editing unit 40, the display line expanding unit 41, the enlargement designation control unit 45, and the display control unit 26. The key line buffer 49 temporarily stores data relating to the key line, and outputs the data to the display line developing unit 41 as necessary. The character generator (CG) 50 stores character font data and outputs the font data to the enlarged cutout unit 51. The enlarged cut-out unit 51 inputs the character code received from the display line developing unit 41 and information such as the enlarged size table and the display information table of the displayed text information unit 44 via the display line developing unit 41, and Character font data is searched for and extracted from the energizer (CG) 50, an enlarged character is cut out based on the information, and enlargement processing is performed according to each enlarged size. Then, this data is displayed on the display device 2 through the display control unit 26 as display font data. When there is a key input for position correction from the input device 1, the position correction designation unit 52 receives this from the input control unit 25, and gives an instruction to display a message as shown in FIG. 16 to the display control unit 26. This information is further output to the text enlargement position correction update unit 53. The text enlarged position correction updating unit 53 outputs the input enlarged position correction data to the text buffer 43 and the display line developing unit 41. Next, the method of displaying the enlarged character designation and the magnification separately for each character unit, which is the operation of the embodiment constructed as described above, will be described with reference to FIGS. FIG. 4 shows the concept of a line when characters of different enlarged sizes are mixed. In this case, the character nma having the largest vertical enlargement size among the characters existing in one line
Detect x and use it as the enlarged size of this row. Then, other characters are regarded as being included in this line and processed. Further, the next line is a position where "line spacing of one line × nmax times" is lower than shown in the figure. If a line is formed in this way, there may be a large gap between lines depending on the character size, but if a continuous character string is arranged according to the character size, the line And the continuity of the character string is difficult to determine, so that such a processing method improves operability. In addition, since the continuity of character strings is not lost, there is an advantage that processing such as character search and recognition can be performed relatively easily. Next, the change of a row will be described with reference to FIG. The character a having the maximum size nmax in the character string shown in FIG.
As shown in the figure, when the maximum enlargement size of a character in one line is changed, the maximum character of the vertical enlargement size is detected again, and the recognition of the vertical enlargement size of this line is changed. It was but connexion, in the example of FIG. 5 enlarged size of the line is changed to n _2. In addition, as shown in FIGS. 4 and 5, characters having an enlargement size smaller than the maximum enlargement size are aligned by matching the upper sides of the line. Here, when the lower-aligned line in FIG. 6 and the center-aligned line in FIG. 7 described later are changed to the upper-aligned line, as shown in the upper-aligned routine in the flowchart of FIG.
All the correction values of the characters in the line are deleted, and the text buffer 43 is also updated. As described above, the space between this line and the next line is a line space obtained by multiplying one line of normal characters by the magnification of the maximum character of this line. It was but connexion, in FIG. 5 from nmax multiple of Figure 4 is changed to ₂ times n. Next, the bottom alignment of the rows will be described with reference to FIG. When aligning to the lower side of the line containing the enlarged characters, as shown in the lower alignment routine in the flowcharts of FIGS. 6 and 15, the character having the maximum vertical enlarged size is set as the enlarged size of this line, and a smaller enlarged size is used. For characters, by inserting the shaded portion in the figure (the difference between the enlarged size of the characters in the line and the maximum enlarged size) as a correction value,
The processing is performed as if the enlarged characters exist as if they are up to the hatched portion. The temporary enlargement size at this time is for detecting the character display position, and has nothing to do with the actual enlargement of the character font. FIG. 7 shows the case of aligning at the center of the line. This will be described with reference to the center alignment routine in the flowchart of FIG. In this case, as in the case of the bottom alignment in FIG. 6, each character in the line is arranged at the center of the line by using the idea of the correction based on the temporary enlarged size. In this case, the temporary enlargement size, that is, the method of calculating the correction value is (maximum enlargement size−enlargement size of character in line) / 2. Here, the enlarged size is a vertical enlarged size. In the above formula, the remainder may be rounded up or down. When the above-described enlarged position correction is instructed by the position correction key of the input device 1,
A message as shown in FIG. 16 is displayed on the screen of the display device 2. Therefore, if "1" is selected from this message display, the message will be aligned on the top and "2" will be displayed.
If "" is selected, it is changed to bottom alignment, and if "3" is selected, it is changed to middle alignment. Next, an enlarged display method will be described with reference to FIG. As shown in FIG. 11, when there is a character of 6 × 6 times “a” and a character of 2 × 2 times “b”, each character is sliced into a 1 × vertical physical line, and each is sliced. A display information table of a cutout position as shown in FIG. In calculating the cutout position, an enlarged size (correction value) for correction is used in addition to the enlarged size of the character. In the case of the character "b", the enlarged size is 2.times.2 with the bottom aligned, but since the correction is from 1, 2, 3, 4 from the top, the correction value is set to "4". Therefore, the table is set so as not to cut out the upper four rows of the physical row slices. At the time of display, font data subjected to enlargement processing based on the enlargement size of these tables and characters is cut out and displayed based on the values of the table along the No. (number) of the physical line to be displayed. Next, a method of specifying an enlarged size will be described with reference to the flowcharts of FIGS. When an input for changing the enlarged size is received from the input device 1, an instruction is transferred to the enlarged size specifying unit 46 via the input control unit 25 in FIG. Enlarged size designation section 46
Then, a message as shown in FIG. 12 is displayed on the display device 2 through the display control unit 26. In this display, the previous enlarged size is displayed. Then, an input of the enlarged size is received. Next, a new vertical and horizontal enlarged size is input to the pointer / enlarged size 1. Then, it is determined whether the input is completed or not and the cursor is moved when further characters are to be enlarged, but the pointer is up when the cursor is moving right, and the pointer is down when the cursor is moving left. Yes, return to the next new enlarged size and enter the enlarged size. Then, it is checked whether the input new enlarged size is the maximum size, and the new enlarged size is stored in the enlarged size storage area 47, and the processing is terminated. When the enlargement size is designated in this way, the designated enlargement size is displayed in the guidance area as shown in FIG. 23, and the enlargement 1 key and the enlargement 2 key are depressed as described below. The magnification of time can be determined immediately. A method of specifying enlargement will be described with reference to the flowchart of FIG. When a character enlargement instruction is received from the input device 1, the instruction is transferred to the enlargement designation control unit 45. The enlargement designation control unit 45 receives the cursor position data from the cursor control unit 48, and calculates a corresponding character address. Then, an enlargement size storage area is selected by a designation key of the enlargement 1 key or the enlargement 2 key. Then, the text buffer 43 is changed so that the enlargement attribute (enlargement designation for the character at the cursor position) is added to the character, and the process is terminated. After the change, the display is requested from the changed line to the display line developing unit 41, and the change of the display by the enlargement designation is realized. Next, the text buffer shown in FIGS. 8 to 10 will be described. First, in the contents of the text buffer 43, when the enlarged character is not specified, the character code is simply continuous as shown in FIG. 8, and when the enlarged character is specified, as shown in FIG. Enlargement ratios n (vertical) and m (horizontal) are added to the characters. In addition, when a temporary enlarged size correction such as center alignment or bottom alignment is performed, a correction magnification n ′ is simultaneously added in addition to n × m times as shown in FIG. In this way, enlargement is specified for each character and enlarged display is performed.
This will be described with reference to the flowchart of FIG. When the above-mentioned text buffer 43 is updated, it requests the display line developing unit 41 to display the updated line. The display line developing unit 41 calculates the text buffer character address of the display request line from the text buffer 46. At this time, the format / format data of the corresponding line to be displayed is sequentially extracted from the format format information section 42. Then, the arrangement possibility range of the character for one line is calculated and determined. When the display characters for one line are determined, the characters are extracted from the text buffer 43, and it is determined whether or not this is a character code. If it is a character code, it is set in a character table with a horizontally enlarged size according to the specified magnification. This operation is repeated for one line. If the result of the determination is not a character code, it is determined whether or not the instruction is an enlargement instruction. If the instruction is an enlargement instruction, the enlargement size is set in a table. If it is not an enlargement instruction, other attribute processing is performed according to the instruction. In the case of an enlargement instruction, the presence or absence of correction is checked for the enlarged size set in the table. Then, if there is a correction, the correction size is set in the fetch table. If there is no correction, the correction size 0 is set in the table. This operation is repeated for one line. When the processing for one line is completed, the maximum vertical enlargement size is detected from the character table and enlargement size table shown in FIG. Then, the physical row number is calculated from the requested row number. Then, a display row is calculated based on the calculated physical row No. Next, a character is extracted from the character table and is subjected to an enlargement process based on the enlargement size. Then, character data is cut out using the display information table. This is set in the display buffer. This operation is repeated until the end of the physical line (from line 1 to line 6 in FIG. 11), and this is displayed at the same time. This process is repeated for one line (logical line) and displayed. FIGS. 18 and 19 are display examples displayed on the screen of the display device 2 by the above-described method, respectively, and are arbitrarily enlarged in character units, and the same print result as this display is obtained at the time of printing. As described above, since the enlargement magnification and the enlargement instruction are separately performed, the instruction of the same magnification can be continuously performed. Since a plurality of enlargement magnifications can be set and an enlargement instruction key is prepared correspondingly, even if the magnification changes as shown in FIG.
It is possible to respond only by changing the enlargement 2 key and the instruction key, and since the magnification is also displayed on the screen as shown in FIG. 23, the designated magnification can be confirmed and operated. In addition, since it is displayed in the actual enlarged size and printed as it is, characters enlarged at the time of printing do not drop out beyond the paper width, and the enlarged print result is taken into account when creating and editing documents as in the past. However, since there is no need to create a document by inputting characters and performing simple processing, a character processing apparatus equipped with a very operable enlargement specifying method can be provided at low cost. Effects As described above, according to the character processing device of the present invention, a plurality of enlarged sizes can be arbitrarily specified, and the enlarged size and the target character or character string can be operably separated from each other. Is simplified, the operability of enlargement for each character or character string can be improved. Also, in the character processing work, it is possible to specify the original enlarged size for each arbitrary character or character string on the screen independently in vertical and horizontal directions, and the actual shape and size can be displayed on the screen. Finally, the created document layout can be finally verified before printing.
