Abstract

PURPOSE:To make an operation easy by overlapping an inclined character having a specified inclination angle to an image at the time of inputting input data including the inclined character specified at its inclination angle to form an overlapped image. CONSTITUTION:The dot development starting position of each line is determined by adding respective dot shift values calculated by a dot shift value calculating procedure to the normal character dot development starting position of each row in respective characters included in the inclined character data by means of a developing position calculating procedure. Then, a character pattern consisting of MXN dots corresponding to each character included in the inclined character data is inputted from a character font file by an inclined character developing procedure. The image data of the inclined character is formed by forming each row of the character pattern from the dot development starting position of each row determined by the developing position calculating means. Consequently, an inclined character 'A' obtained by moving 24 bits in the uppermost row to the right by 13 dots can be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slanted character generation method, and more particularly to a slanted character generation method for folding and outputting a series of slanted characters within ordinary characters to be printed.

[Conventional technology]

If conventional slanted character generation methods are limited to graphical processing, there is an example in which slanted characters are generated by specifying a slant angle for a stroke character represented by coordinates and performing coordinate conversion.

However, in the -i text editing process, in addition to the normal character font, a character font for slanted characters such as italics is used to generate slanted characters.

[Problem to be solved by the invention]

Among the conventional slanted character generation methods described above, the former method using coordinate transformation of stroke characters has the disadvantage that it is limited to graphical processing having the function of stroke characters.

The latter method of using a specific character pattern either requires that the operating system owns a character font with slanted characters such as italics, or if it does not have a character font with slanted characters, registers the external characters and creates a font with slanted characters. The problem is that it has to be done.

An object of the present invention is to perform a character editing process using an information processing system that can print out overlapping characters and images. An object of the present invention is to provide a slanted character generation method that can easily generate slanted characters having a slant angle by superimposing them on an image.

[Means to solve the problem]

The slanted character generation method of the present invention is as follows: (A) If the read input data is slanted character data,
In order to convert a normal character formed by a rectangle of M×N dots into a slanted character formed by a parallelogram of M×N dots with a specified slope angle, the N dot positions of each line are A dot shift value calculation procedure for calculating M dot shift values to be moved, (B) For each character included in the slanted character data,
A development position calculation procedure that determines the dot development start position of each line by adding the dot shift value calculated in the above dot shift value calculation procedure to the dot development start position for normal characters in each line, (C) Included in slanted character data For each character,
By inputting the corresponding M×N dot character pattern from the character font file and forming each line of the character pattern from the dot development start position of each line determined in the development position calculation procedure, the image data of the slanted character is created. (D) If the input data read following the slanted character data is normal character data, in order to align the normal character development position with the characters on other lines, the beginning of the normal character data is A vertical position adjustment procedure that moves the dot expansion start position for the character until it aligns with the character position on another line. A normal character development procedure for forming image data of a normal character by inputting a corresponding M×N dot character pattern and forming each line of the character pattern from the dot development start position determined in the column position adjustment procedure. It is configured with the following.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a flowchart showing one embodiment of the slanted character generation method of the present invention.

When performing character editing processing in an information processing system that can print out text and images in an overlapping manner, as shown in Figure 1, first, in format information reading procedure 1, printout is performed from format definition file F1. Loading the format definition for

Further, in the input data reading procedure 2, input data that is the content to be printed out is read from the input data file F2.

Therefore, in the next step 3, it is determined whether the read input data is slanted character data.

In step 3, if the read input data is slanted character data (YES'), in the next dot shift value calculation step 4, normal characters formed by a rectangle of M x N dots are converted to the specified slant angle. In order to convert the character into a slanted character formed by a parallelogram of M×N dots, M dot shift values are calculated to respectively shift the N dot positions in each line.

FIG. 2 is an explanatory diagram of a tilted character showing an example of tilting the letter "A" by 30 degrees to the right.

As shown on the left side of Fig. 2, when the normal character "'A" formed by 24x24 dots is tilted 30 degrees to the right, the position of the 24 light dots in each line is The 24 dot shift values for moving each are calculated in order from the top row as shown below.

23Xtan30°=13.3 → 1322Xta
n30°=12.7 → 133Xtan30°=
1, 7 → 22 × tan 3
0° = 1, 2 → 11Xtan30
”= 0.6 → 10xtan30°
= 0 → 0 Next, in the expansion position calculation step 5, for each character included in the slanted character data, the dot expansion start position for 'iY regular characters in each line is
By adding the dot shift values calculated by the dot shift value calculator Jllff 4, the dot development start position of each row is determined.

Furthermore, in the slanted character development step 6, for each character included in the slanted character data, the corresponding M×N dot character pattern is input from the character font file F3, and each line determined in the development position calculation step 5 is input. The image data of the slanted character is formed by forming each line of the character pattern from the dot development start position.

As a result, in the example shown in FIG. 2, the 24 bits in the top row can be moved 13 dots to the right to form the slanted character "A" shown on the right in FIG.

In the next step 7, it is determined whether or not the characters included in the slanted character data have been completed.

In step 7, if the characters included in the slanted character data have not been completed (No), the process returns to development position calculation step 5 and moves on to processing the next character.

Furthermore, if the read input data is not slanted character data (No) in step 3, then in the next column position adjustment step 8, since the input data read following the slanted character data is normal character data, In order to align the character expansion position with the characters on other lines, the dot expansion start position for the first character of the ordinary character data is determined by moving the character until it is aligned with the character position on the other line.

Furthermore, the ordinary character expansion procedure inputs the corresponding M×N dot character pattern from the character font file F3 for each character included in the ordinary character data, and then inputs the dots determined by the vertical position adjustment procedure 9. By forming each line of a character pattern from the development start position, image data of ordinary characters is formed.

In the next step 10, it is determined whether or not the characters included in the normal character data have ended.

If the characters included in the normal character data are not completed (No) in step 0, the process returns to the normal character expansion procedure 9 and moves on to processing the next character.

Also, in steps 7 and 10, the characters included in the slanted character data or normal character data have ended (Y
ES), in the next step 11 it is determined whether all input data has been input.

In step 11, if all the input data has not been completed (NO), the process returns to the input data reading procedure 2 and moves on to processing the next input data.

Note that if all the input data has been completed (YES) in step 11, the last image data printing procedure 1 is executed.
In step 2, the image data including slanted characters and normal characters is printed out to the output printer P in a format based on the format definition read by format information reading procedure 1, and the process ends.

As described above, the slanted character generation method of this embodiment can print out overlapping characters and images even in an information processing system that does not have a stroke character function or a character font for slanted characters. When performing character editing processing in an information processing system, it is possible to easily generate a slanted character having a specified slant angle by superimposing it on an image for input data including a slanted character with a specified slant angle.

〔Effect of the invention〕

As explained above, the slanted character generation method of the present invention includes a slanted character whose slant angle is specified when performing character editing processing in an information processing system that can print out overlapping characters and images. This method has the effect that it is possible to easily generate oblique characters having a specified inclination angle with respect to input data by superimposing them on an image.
