Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a right-edge aligned printing method of proportional data for aligning the right ends of proportional data when a proportional font is used in a word processor, typewriter or the like for collectively printing text for at least one line. .

[0002]

2. Description of the Related Art Generally, in a word processor or typewriter having a justification function, when aligning the right ends of European texts, an editor analyzes the Western texts in one line and adjusts the white space according to the character size. To align the right ends of the lines.

[0003]

However, in the case of adjusting the white space between words by such a justification function, in a proportional font having a unique character width for each character, the right end is always aligned exactly. However, there are drawbacks such as poor printing results. SUMMARY OF THE INVENTION An object of the present invention is to enable the right end of each line to be accurately aligned and printed in dot units even when a proportional font is used.

[0004]

Means for Solving the Problem and Its Action The means of the present invention and its action are as follows. (1) Prior to arranging at least one line of proportional data as print data in the expansion memory (for example, one line of print buffer), each of the at least one line except for spaces between words is preliminarily read The cumulative number of dots of proportional data is calculated by accumulating the character width (font body size) of proportional data in dots, and the total number of spaces in half-width is calculated by counting the spaces between words in half-width units. Ask for TSP. (2) Further, the dot size from the predetermined position on the left side of the line to the right margin position is obtained as the expansion area size DVA for expanding the proportional data, and the cumulative dod count ACD of proportional data is subtracted from the expansion area size DVA. To obtain the blank allocation size SAL in dot units. (3) If proportional data is read when sequentially reading the contents of the text memory and arranging them in the expansion memory, the proportional data is directly arranged in the expansion memory as in the usual case, and is blank. When data is read, the current number of blanks PS indicating how many blank data is currently being read in half-width units
In addition to obtaining C, the total number of blanks in half-width units TSP is divided by the current number of blanks PSC, and the value is multiplied by the blank allocation size SAL to obtain the value as the number of blank dots PSD for the blank data currently being read. A blank for the number of levers is arranged in the expanded memory, and the current blank dot number PSD is subtracted from the blank allocation size SAL to obtain the value as the blank allocation size SAL for the next blank calculation. The current blank count PSC is subtracted from the unit total blank count TSP to obtain the value as the total blank count TSP for the next blank calculation. Such processing is executed each time the text data is read out character by character. Therefore, even when a proportional font is used, the right ends of the lines can be accurately aligned and printed in dot units.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing the overall configuration of a word processor. A CPU 1 is a central processing unit for controlling the overall operation of this word processor, and a keyboard 3 and a CR which are peripheral devices thereof according to an IOCS program for input / output control stored in a ROM 2.
Input / output control is performed for the T display device 4, the disk 5, and the printer 6. It should be noted that the ROM 2 is an I for loading the operating system into the RAM 7 when the system is started up.
It is a fixed memory that stores character font data (proportional data) and the like in addition to the PL program and the IOCS program.

The keyboard 3 is a key input device for inputting text data and various commands, and the CPU 1 accesses the key code held in the keyboard control section 8, and if it is a text code, it executes a document creation process. And store it in the text memory 7-1 in RAM7,
It is converted into display data and written in the video RAM (V.RAM) 9. The CRT control unit 10 accesses the V.RAM 9 and causes the CRT display device 4 to display and output the text data in the V.RAM 9.

The RAM 7 has a text memory 7-1, a work memory 7-2, etc. When a print command is given from the keyboard 3, the CPU 1 reads the contents of the text memory 7-1 and gives it to the print buffer 11. The print buffer 11 is a one-line buffer in which one line of text data is expanded and arranged as print data, and the print control unit 12 prints out the contents of the print buffer 11 in a batch.
Here, when the CPU 1 prints the right edge of proportional data, the RAM 7 follows a predetermined calculation procedure.
While calculating various parameters described later, proportionality data justification processing for adjusting the size of each blank existing between words in one line in dot units is performed. When a document save command is input from the keyboard 3, the CPU 1 gives the content of the text memory 7-1 to the external storage control unit 13 to register it in the floppy disk 5.

FIG. 2 is a diagram showing the configuration of the RAM 7 in detail. The RAM 7 has a text memory 7-1, a work memory 7-2, and the like, and is configured to store various parameters necessary for justification processing of proportional data. Here, various parameters are defined as follows. Text address TXA ... Current read address for accessing the text memory 7-1. Digit count CCT: A counter value that counts the number of digits from the beginning of the line to the end of the line in half-width units when printing one line. Cumulative number of proportional data ACD: Character width of one line of proportional data (font body size) before the space for one line of proportional data is expanded and arranged in the print buffer 11 as print data. The total number of dots obtained by accumulating in dot units. Character count ONC: A counter value that counts the number of characters in a line excluding blanks in half-width units when printing one line. Total number of blanks TSP: A counter value that counts each blank existing between words in one line in half-width units during one-line printing processing. Save address TSA: Text address of the last character in the last word of one line. Expansion area size DVA: The dot size from the specified position on the line to the right margin position is the dot size obtained as the area for expanding the proportional data. Blank allocation size SAL ... Development area size DVA
This space allocation size SAL is evenly allocated to each space between words with a dot size obtained by subtracting the cumulative number of proportional data ACD from ACD. Current number of blanks PSC ... When the blank code is read when sequentially reading the contents of the text memory 7-1 and arranging them in the print buffer 11, how many blank codes correspond to one half-width unit. Indicates the number of blanks currently being read. Current number of blank dots PSD ... Blank allocation size SA
L × total number of blanks in half-width units TSP / current number of blanks PSC
By the number of dots obtained by executing the operation of
Print buffer 1 corresponding to the blank data currently being read
The number of blank dots to be expanded and arranged in 1.

FIG. 3 shows an example of the alphabetic character "J" as a specific example of proportional data. In general, proportional data includes first left side bearing information a, second left side bearing information b, and font body size c. , The right side bearing information d, and the print buffer 1 with proportional data as print data
When expanding and arranging to 1, the character arrangement is performed according to the font body size. Note that the first character of each line of the proportional data is the first left side bearing information so that the left end of the proportional data does not protrude from the left margin position.
The left side bearing information a is used.

The operation of this embodiment will be described below with reference to the flow charts shown in FIGS. FIG. 4 is a flowchart in the case of performing right edge alignment printing of proportional data, which is started every time one line is printed. First, the CPU
1 executes an initialization process for initializing the digit count CCT in the RAM 7 and the cumulative number ACD of proportional data in the beginning of one-line printing (step A).
1) Next, it is checked whether or not the start condition of the prefetching process performed as a process before arranging the proportional data for one line as print data in the print buffer 11 is satisfied (step A2). Here, the start of the prefetch process is conditioned on the fact that the next character is read after the first character of the first word excluding the blank at the beginning of the line is read from the text memory 7-1. In the one-line text string shown in FIG. 9, the read-ahead processing is started on the condition that the character B following the leading character A is read from the text memory 7-1 except for the blank at the beginning of the line. In addition,
The text example of FIG. 9 schematically shows the text contents, and is different from FIG. 12 to be described later in that the text example is filled with a blank code from the last character position to the right margin position.

If the prefetch start condition is not satisfied,
In step A3, the text code read from the text memory 7-1 is expanded into print data and characters are arranged in the print buffer 11 as usual. In this case, as described above, the first left bearing information a is used for the first character proportional data so as not to jump out of the left margin position. Next, the text address TXA in RAM7,
The digit count CCT is updated (step A4). Then, returning to step A2, the start condition of the prefetching process is checked again.

Here, in the text example of FIG.
When the character B is read, the start condition of the prefetching process is satisfied and the process proceeds to step A5, and the current text address TXA and digit count CCT are saved in the save memory (not shown) in the RAM 7. deep. In this case, "3" is stored as the text address TXA and "3" is stored as the digit count CCT. Then, a process of accumulating proportional data (step A6) is performed.

FIG. 5 is a flowchart showing the process of accumulating the proportional data. First, the proportional data corresponding to the text code currently being read is read (step B1). If the text code is not blank (step B2). ), The font body size (c in FIG. 3) of the read proportional data is taken out, and a value for the dot size corresponding to the current font body size c is accumulated in the cumulative dot number ACD in the RAM 7 (step B3).

When such a stacking process is completed, the process proceeds to step A7 in FIG. 4 to analyze the number of characters and the number of blanks. The number of characters / blanks analysis process counts the number of characters in one line in half-width units from the position where the pre-reading process start condition is satisfied to obtain the total number of characters, and also counts each space between words in half-width units. Is a process for obtaining the total number of blanks.

FIG. 6 is a flow chart showing this character number / blank number analysis processing. First, the CPU 1 checks whether the currently read text code is a character or a blank (step C1). If it is a character code, the number of half-width units of the current character is calculated, and the character number count CNC in the RAM 7 is incremented according to the calculated value (step C2). Then, the current text address TXA is set in the RAM 7 as the save address TSA. Such processing is executed every time the character code is read from the text memory 7-1. As a result, when the character code located at the end of the last word in one line is read, the character number count C
The value of NC is the number of characters in one-byte unit in one line, and
The save address TSA becomes a text address when the last character of the last word is read. In this case, the save address TSA is “9” in the text example of FIG.

On the other hand, when the blank code is read from the text memory 7-1, the process proceeds to step C4, the number of half-width units of the current blank is calculated, and the calculated blank space is calculated. The value is accumulated in the temporary save buffer (not shown) in the RAM 7. The temporary save buffer is for saving a temporary count value in order to obtain the total number of blank spaces TSP by counting only the number of blank spaces between words in half-width units. Then, it is checked whether the next text code is a character or a blank (step C5). Here, when the next text code is a blank and the blanks are continuous, the analysis processing of FIG. 6 is skipped, but when the next text code is a character, that is, when it is the first character of the next word, , RAM7 according to the contents of the temporary save buffer
The total number of blank spaces TSP is incremented (step C6) and the contents of the temporary save buffer are cleared (step C7). That is, the contents of the temporary save buffer are accumulated accordingly when the blanks are continuous, but when the first character of the next word is found, the contents are initialized. Text memory 7
As a result of being executed each time a blank code is read from -1, the value of the total number of blanks TSP in the RAM 7 becomes the number of blanks in half-width units of each blank existing between words. That is, as shown in the text example of FIG. 9, even if a blank code is inserted at the end of the line from the character position at the end of the last word to the right margin position, this blank is not counted in the total number of blank spaces TSP. It is cut off as it is. Therefore, the total number of blanks T
The value of SP is a total value obtained by counting each blank existing between words in half-width units.

When the character number / blank count analysis process is completed, the process proceeds to step A8 in FIG. 4 to check whether the prefetch process termination condition is satisfied. Here, the prefetch process end condition is (1) when the current digit count CCT value becomes equal to the right margin position. (2) When the current text address TXA becomes equal to the end address of the line. (3) When the line feed code is read from the text memory 7-1. (4) When the text to be printed is finished. Etc. Here, if the satisfaction of the termination condition is not detected,
The process proceeds to step A9 and the text address T in the RAM 7
After updating the XA and digit count CCT, the process proceeds to step A6, and if the next text code is a character, the proportional data is accumulated. Thereafter, similar processing (proportional data stacking processing and character count / blank count analysis processing) is executed for each character.

When the end condition of the prefetching process is detected, the process is performed thereafter. That is, R in step A5
The text address and digit count stored in the save memory in AM7 are read out and returned in RAM7 as text address TXA and digit count CCT (step A10). Next, it is checked whether it ends with a line feed code or there is no space between words (step A11). Here, in order not to end with a line feed code or to align the right end of the proportional data when there is no space between words, the process proceeds to step A13, while updating the text address TXA and the digit count CCT. The text code is read from the text memory 7-1 one character at a time, developed into print data, and placed in the print buffer 11. That is, in the above case, one line of text is expanded and arranged as usual. Then, the cumulative dot number ACD and the character number count CN of proportional data required for right edge alignment
C, the total number of blanks TSP, etc. are initialized (step A
14).

On the other hand, if the processing is not completed under the conditions shown in step A11, the process proceeds to step A12 to perform a blank allocation size calculation process. In this blank allocation size calculation processing, the dot size from the predetermined position on the left side of the line to the right margin position is obtained as the expanded area size DVA for expanding the proportional data, and then the accumulated dot number A of the proportional data is calculated from the expanded area size DVA.
This is a process of obtaining the blank allocation size SAL by subtracting CD.

FIG. 7 is a flow chart showing this blank allocation size calculation processing. First, the right margin digit position is read from the preset setting format, and the expansion area digit size is obtained by subtracting the value of the current digit count CCT from this right margin digit position (step D1). For example, as shown in FIG. 9, when the right margin position is X and the expanded area digit size is Y, the operation of "Y = X-digit count CCT" is performed. Here, when the right margin position is "14" and the digit count CCT is "3", the expanded area digit size Y is "11". In the next step D2, a virtual development area dot size is obtained using the development area digit size Y thus obtained.
Here, assuming that the virtual expansion area dot size is Z, the virtual expansion area dot size Z is calculated by performing the following operation: Z = Y + (number of half-width unit of character just before starting prefetching) × half-width digit pitch dot size (See FIG. 9). It should be noted that the character just before starting prefetching is the first character A in the text example of FIG. 9, and the number of half-width units of this character indicates how many half-width units it corresponds to. In the example, it is “1”.

After the dot size Z of the virtual development area is calculated in this way, it is used in the next step D.
In 3, the actual dot size of the development area is obtained. Here, the font body size C in the proportional data of the character just before the prefetch is obtained, and the "expansion area size DVA = Z-C" is calculated to obtain the substantial expansion area dot size DVA.
(Step D4). Next, the blank allocation size SAL is calculated (step D5). In this case, blank allocation size SAL = expanded area size DVA−
The blank allocation size SAL is obtained by calculating the cumulative dot number ACD of the proportional data, and this is stored in the RAM 7 (step D6). When the blank allocation size SAL is calculated in this way, first, the expansion area digit size Y is calculated, and the dot size Z of the virtual expansion area is calculated using this. Next, the substantial development area size DVA is obtained from the virtual development area dot size Z. Furthermore, this development area size DVA
The blank allocation size SAL is obtained by subtracting the cumulative dot number ACD of the proportional data from.

Then, the process proceeds to step A15 in FIG. 4, and the look-ahead character arrangement process is performed. FIG. 8 is a flow chart showing this prefetching character arrangement processing. First, the text memory 7-1 is accessed according to the text address TXA, whereby it is checked whether the text code currently being read is blank (step E1). When the character code is read out, the proportional data is expanded and arranged in the print buffer 11 as usual (step E2). Then, the print offset of the next character is obtained (step E3).

On the other hand, if the text code currently being read is a blank code, the process proceeds to step E4 to calculate the current blank number PSC. That is, the current number of blanks PS, which indicates how many blanks are currently being read in half-width units
C is obtained, and using this, the present number of blank dots PSD is obtained in the next step E5. Here, the current blank dot number PSD is the current blank dot number PSD = blank allocation size SAL
Calculated by the calculation of × (total number of blanks TSP / current number of blanks PSC). Next, the space allocation size SAL for the next space calculation is calculated according to the following formula and RA
Keep at M7. Blank allocation size SAL = Blank allocation size SAL
-Current blank dot number PSD Further, the total blank number TSP for the next blank calculation is calculated according to the following equation and stored in the RAM 7 (step E
7). Total number of blanks TSP = Total number of blanks TSP-Current number of blanks P
SC Next, the present number of blank dots PSD obtained as described above
A minute blank is generated and developed and arranged in the print buffer 11 (step E8). Then, the print offset of the next character is obtained (step E9).

As described above, when the blanks are developed and arranged in the print buffer 11, the current blank dot number PSD is obtained according to the above-described calculation procedure and the blanks are arranged, so that the spaces between the words are uniform. For example, in the text example of FIG. 9, when the blank code between the characters B and C is read, “blank allocation size SAL × 1/2 = current blank dot number P
"SD" is performed, and when a blank code between the following characters D and E is read, "blank allocation size SA
L × 1/1 = current number of blank dots PSD ”is calculated.

Similarly, in the text example shown in FIG. 10, the space between the first word is full-width, half-width, and the space between the next words is half-width,
Since it is full-width, the total number of blanks TSP is "6". In this case, when the first full-width blank code is read, the calculation of "blank allocation size SAL x 2/6 = current blank dot number PSD" is performed. When the next half-width blank code is read, "blank allocation size SAL x 1/4 = current blank dot number PSD"
When the last full-width blank is read, the calculation of "blank allocation size SAL x 2/2 = current blank dot number PSD" is performed.

Next, in step A16 of FIG. 4, the current text address TXA is compared with the save address TSA to check whether they match. Here, the save address TSA is the text address saved in step C3 of FIG. 6, and this text address is the text address when the last character of the last word is read at the stage when the prefetching process is completed. Now, in the case where the text is modified by shading or underlining, even after all the text for one line is expanded and arranged in the print buffer 11, the line end portion of the text is shaded. If you do, the shaded parts at the end of the line will be expanded and arranged. In order to prevent this, in step A16, the character arrangement is forcibly ended when the text address TXA reaches the save address TSA. That is, FIG.
As shown in, if the whole text for one line is shaded (the blank from the character position at the end of the last word to the right margin position is also shaded), In order to prevent the shaded lines at the end of the line from being expanded and arranged in the print buffer 11, the character arrangement is forcibly terminated when the text address TXA reaches the save address TSA. Therefore,
It is possible to specify the character decoration without worrying about whether the half-tone or the underline will be applied to the white space at the end of the line when entering the text.

When it is detected in step A16 that the text address TXA has not reached the save address TSA, the process proceeds to step A17, where the text address TA is reached.
Step A after updating XA and digit count CCT
Returning to step 15, the look-ahead character arrangement process is repeated in the same manner. Here, when the text address TXA matches the save address TSA, it is determined that the printing of one line is completed, the process proceeds to step A18, and the line count (not shown) in the RAM 7 is updated. This completes the one-line printing process. Hereinafter, the above-described one-line printing process is repeated until all the contents of the text memory 7-1 to be printed are printed. As a result, even when a proportional font is used, the right ends of the lines can be accurately aligned and printed in dot units.

FIG. 9 shows an example of the text when the space from the last character position to the right margin position is filled with a blank code. As shown in FIG. 12, the text from the last character position to the right margin position is a blank text. Even if there is, it is processed in the same manner as in the case of FIG. In other words, even if a blank code is inserted at the end of a line or no blank code is input, the justification process for aligning the right edge of proportional data is not affected at all, and the right edge of each line can be aligned exactly.

FIG. 13 shows an example of text in the case where enlarged characters exist. Even when characters having different enlargement ratios are mixed, when the cumulative dot number ACD of proportional data is obtained, the magnification of the characters is set to the font body of proportional data. Accumulate to size. Further, in the digit count CCT that counts the number of digits in half-width units, a value for half-width numbers indicating the number of half-width units in the case of enlarged characters is accumulated. Therefore, even if the enlarged characters are mixed, it does not affect the justification process of proportional data, and the right ends of the lines can be aligned exactly as in the case described above.

FIG. 14 shows an actual printing example, FIG. 14A shows a printing example when the right edge alignment of proportional data is not performed, and FIG. 14B shows a print example when the right edge alignment is performed. As shown in FIG. 14B, the right ends of the lines are accurately aligned, and printing can be performed without any variation. In this case, since the justification process is not performed for the line feed mark position added for convenience in FIG. 14A, the right end of the line is the line feed position. The final dot position of the character whose right ends are aligned is equal to the final position of the font body size of the proportional data.

FIG. 15 is a print example of text in which text is shaded and underlined. Here, FIG.
As shown in FIG. 15A, in the first line and the second line of the text, even if the last character position is shaded at the end of the line, in the present embodiment, as shown in FIG. As shown in B), when the right edge alignment printing of the proportional data is performed, the decoration of that portion is cut at the right edge alignment position, and the print does not largely extend from that position. In addition, the right end position such as shading and underline is the right side bearing position of proportional data.

FIG. 16 shows an example of text printing in the case where enlarged characters are included. Even if the characters having different enlargement ratios are mixed in the text, the right end positions of the lines are correctly aligned as in the case described above. It is the same. This is because enlarged characters are processed in half-width units.

As described above, in this embodiment, when printing one line of text, a blank code is inserted at the end of the line from the last character position to the right margin position, or the end of the line is not entered. Exactly, each line of proportional data is aligned in dot units, regardless of whether there is a decoration such as shading or underlining at the end of the line, or whether the text contains enlarged characters. It becomes possible.

In the above embodiment, the print buffer 11 has one
Although the proportional data for the line is expanded and arranged, the page memory may be used as the print buffer 11 and the proportional data for one page may be expanded and arranged. Further, in the above embodiment, the pre-reading process performed before expanding and arranging the proportional data as the print data in the print buffer 11 is started from the second character except the first character at the beginning of the line. The look-ahead process may be started from the first character of the first character.

[0035]

According to the present invention, before arranging at least one row of proportional data in the expansion memory,
When calculating various parameters required for right edge alignment of proportional data and sequentially reading the contents of the text memory and arranging them in the expansion memory, calculate the number of blank dots based on various parameters and insert them between words. Therefore, even when the proportional font is used, the right ends of the lines can be accurately aligned and printed in units of one dot.
