[Detailed Description of the Invention] [Summary] Recognizing character strings that are not displayed, regarding a display control method for character strings that overflow the bottom end in character editing processing for text whose line pitch varies depending on characters of various sizes. This is a display control method for character strings overflowing at the bottom end in character editing processing for text whose line pitch varies depending on characters of various sizes, with the aim of making editing easier. , a character display section consisting of an overflow determination section and a line display/character continuation mark display control section, and a baseline calculation section that calculates the baseline position on the screen for the input character string and calculates the baseline position on the screen. The result is output to the overflow determination unit, and the overflow determination unit determines whether or not the bottom end of the input character string overflows beyond the bottom end of the display area for each line of the input character string, based on its baseline position and display area. The result is output to the line display/character continuation mark display control unit. If it is determined that the input character string does not exist, the character string is displayed as is in the display area of the display, and if it is determined that the input character string has overflowed the bottom end, the character string is displayed without overflowing the bottom end of the input character string. The part of the character string that is overflowing is not displayed in the display area, and a predetermined character continuation mark is displayed at the beginning of the character string that is overflowing at the bottom, instead of the character string that is overflowing at the bottom. However, when a character continuation mark is specified during editing processing, control is performed so that editing processing is performed on the assumption that a character string that is overflowing at the bottom has been specified.

[Industrial application field]

The present invention relates to a display control method for character strings that are overflowing at the bottom in character processing for text whose line pitch varies depending on characters of various sizes.

In recent years, multimedia editors have become available that perform editing processing on a display screen without distinguishing between characters, figures, and images.

On the display screen of the multimedia editor, a display area is displayed with broken lines to represent the printable area. Characters, figures, and images entered beyond this display area will not be displayed on the display screen. In particular, when characters are input beyond the display area, it is difficult to recognize the part of the character string input beyond the display area unless the characters are displayed on the display screen, making editing and other processing difficult. Measures were needed to solve this problem.

[Conventional technology]

FIG. 7 is a processing flow diagram of a conventional example.

Hereinafter, a conventional example will be explained using FIG. 7.

Enter characters using a keyboard, etc.

Determine whether the input character string is overflowing at the bottom end. If NO, continue processing, inputting characters, if YES,
Execute the process.

Display messages that cannot be entered on the display screen.

Return to the state before input.

As described above, in the conventional example, a character string that exceeds the display area of the display screen and causes the lower end to overflow is not input, and therefore is not displayed on the display screen.

Furthermore, as a second conventional example, a method has been considered in which a character string that causes the lower end overflow is inputted, but nothing is displayed in the display area of the display screen.

[Problem that the invention seeks to solve]

In the conventional example, it is not possible to input a character string that causes the lower end to overflow, resulting in the problem that only a part of the desired character string can be input.

In addition, in the second conventional example, in which a character string that overflows the bottom end is input, but nothing is displayed in the display area of the display screen, when editing a character string, the entire character string is moved and then It is necessary to display all characters on the display screen, but this is difficult to do because the bottom edge overflows and it is difficult to recognize character strings that are not displayed in the display area. A problem had arisen.

The present invention provides a display control method for character strings overflowing at the bottom in character editing processing, which facilitates recognition of character strings that are not displayed, eliminates restrictions on the number of input characters, and facilitates editing of character strings. The purpose is to

[Means for solving problems]

The present invention is a display control method for character strings overflowing at the bottom in character editing processing for text in which the line pitch varies depending on characters of various sizes. It is equipped with a character display unit consisting of a display/character continuation mark display control unit, and a baseline calculation unit calculates the baseline position on the screen for the input character string and outputs the result to the overflow determination unit. However, the overflow determination unit determines whether the bottom edge of the input string overflows beyond the bottom edge of the display area for each line of the input string by comparing its baseline position with the bottom edge of the display area. The result is output to the line display/character continuation mark display control section, and the line display/character continuation mark display control section determines that the input character string does not overflow at the bottom end. displays the string as is in the display area of the display, and if it is determined that the input string is overflowing at the bottom, the part of the string that is overflowing at the bottom is A predetermined character continuation mark is displayed at the beginning of the character string that is not displayed in the display area and is overflowing at the bottom, instead of the character string that is overflowing at the bottom, and the character is continued during editing processing. When a mark is specified, control is performed so that editing processing is performed on the assumption that the character string causing the bottom overflow has been specified.

FIG. 1 is a diagram explaining the principle of the present invention.

In FIG. 1, 1 is an input/editing section, 2 is an editing character selection control section, 3 is an editing character data control section, and 4 is an editing section.
5 is a character display section, 5 is a baseline calculation section, 6 is an overflow determination section, 7 is a line display/character continuation mark display control section, and 8 is a display.

The input/edit section 1 includes an edit character selection control section 2 and an edit character data control section 3.

The editing character selection control section 2 selects characters from text whose line pitch varies depending on characters of various sizes to be edited. The reason for selection also extends to character strings that are overflowing at the bottom. Further, in the same way as other displayed characters, a character continuation mark, which will be described later, can also be selected.

The edited character data control unit 3 performs data control of text characters whose line pitch varies depending on the characters of various sizes to be edited.

The character display section 4 includes a baseline calculation section 5, an overflow determination section 6, and a line display/character continuation mark display control section 7.

The baseline calculation unit 5 calculates the baseline position of the lower end of the character string of the text whose line pitch varies depending on the input characters of various sizes, and notifies the overflow determination unit 6 of the result.

The overflow determining unit 6 displays the character string on the screen of the display 8 from the baseline position of the character string of the text whose line pitch changes depending on the input characters of various sizes, which is notified from the baseline calculation unit 5. Determine whether the area is overflowing from the bottom end,
The result is line display/character continuation mark display control unit 7
Notify.

As a result of the notification from the overflow determination unit 6, the line display/character continuation mark display control unit 7 determines if there is no bottom overflow in the text string whose line pitch varies depending on the input characters of various sizes. If a character string is displayed as it is in the display area of the display 8 screen, and the lower end of the text string whose line pitch changes depending on the input characters of various sizes is overflowing, the display on the display 8 screen will change. Control is performed to display a predetermined character continuation mark at the head position of the character string instead of displaying one line of character string in the area.

The character continuation mark represents all overflowing character strings and is included in the editing target. In other words, it not only represents the result of overflowing the lower end of a character string, but also represents the overflowing character strings together.

On the screen of the display 8, a display area is displayed with broken lines to represent the printable area.

[Effect]

For text strings whose line pitch varies depending on the input characters of various sizes, the baseline calculation section 5 calculates the baseline position of the bottom end of the string, and the result is notified to the overflow judgment section 6. be done.

Based on the notification from the baseline calculation unit 5, the overflow determination unit 6 determines whether the text string whose line pitch varies depending on input characters of various sizes exceeds the lower end of the display area on the screen of the display 8. Determine whether it is overflowing. The result is notified to the line display/character continuation mark display control section 7.

The line display/character continuation mark display control unit 7 performs the following processing depending on the type of notification from the overflow determination unit 6.

(1) If the lower end of a character string of text whose line pitch varies depending on input characters of various sizes does not overflow at the bottom end, the character string is displayed as is in the display area of the screen of the display 8.

(2) If the bottom overflow occurs in a string of text whose line pitch changes depending on the input characters of various sizes, the string in the part where the bottom overflow occurs will be displayed within the display area of the display 8 screen. Control is performed so that a predetermined character continuation mark is displayed at the beginning of the character string so that the character string can be edited as a whole without being displayed in the .

A more specific explanation will be given below using FIGS. 2 to 4.

FIG. 2 is a diagram showing the relationship between the lower end of the display area and the overflow of the lower end of characters.

In Figure 2, the characters displayed in the display area on the display screen are shown as solid rectangles, and the lower end of the display area exceeds the bottom edge of the display screen, causing the characters to be displayed on the display screen. Characters that are not included are indicated by dashed boxes.

FIG. 3 is a diagram showing an example in which a character continuation mark is displayed.

As shown in Figure 2, if there are characters that are overflowing, these characters will not be displayed in the display area of the display screen, but instead will be displayed at the beginning of these characters as shown in Figure 3. As an example,
Display a predetermined character continuation mark.

FIG. 4 is a diagram showing an example of a case where overflow of characters is eliminated.

As a result of editing the character string, if the character string causing the bottom overflow no longer exists, the character continuation mark is deleted, as shown in FIG.
