BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying selected vector characters, and more particularly, to a method for displaying selected vector characters.

0002

[Prior Art] Traditionally, normal characters, in which character codes such as JIS codes are expanded into standard-sized dot patterns, and vector characters, in which the character code is expressed as vector data and displayed at an arbitrary magnification, are mixed and output. There is a word processor that does this.

In a word processor, when a selection is made to designate a range for editing, such as deleting or copying a displayed character string, the selected character string is displayed in reverse video.

0004

[Problems to be Solved by the Invention] Conventionally, when a character string of vector characters displayed as shown in FIG. 4(A) is selected, this vector character is replaced with a normal character and displayed in reverse video as shown in FIG. 4(B). are doing. This is because vector characters overlap with other regular characters, making it impossible to distinguish some of the overlapping regular characters, and because vector characters are displayed using vector data and enlarged at an arbitrary magnification, they are larger than regular characters. This is because it takes a long time and the display response is poor.

Since the selected vector character string is replaced with the normal character and displayed in reverse, there is a problem in that the vector character string cannot be seen in the actual display or print image during editing.

[0006] The present invention has been made in view of the above points.
It is an object of the present invention to provide a display method for selected vector characters, which displays a vector character string selected at the time of editing in a manner closer to the actual display or print image.

[0007]

[Means for Solving the Problems] The display method of selected vector characters of the present invention includes normal characters displayed in a standard size,
A display method for selected vector characters in which vector characters selected for editing are displayed on a word processor that outputs vector characters displayed at an arbitrary magnification, and the selected vector characters are converted to normal characters and selected at the same time. A number of blank ordinary characters that match the digit width of the vector character are added, and the ordinary characters converted from the vector characters and the blank ordinary characters are displayed in reverse video.

[0008]

[Operation] In the present invention, since the selected vector characters are converted into normal characters and displayed, the display response is good and the display can be performed at high speed. Since normal blank characters are added as many as the matching characters, the image is close to the actual display and print image, and since the image is displayed in reverse, smooth editing operations can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a block diagram of an embodiment of the method of the present invention.

In the figure, 11 is a character string display control section;
The character string to be displayed on the display is controlled, and the characters of the selected character string are supplied with an attribute for instructing their inverted display to the one-character display control section 12.

[0011] Single character display control section 12 reads information on a specified character from text buffer 13 . The text buffer 13 stores character strings to be displayed and attributes of each character as shown in FIG. In Figure 2, the first and third lines store the character code of the character string ``Normal Character'' and a flag indicating that each character is a normal character (indicated as ``Tsu'' in the figure). The second line is the character code of the character string "vector" and a flag indicating that each character is a vector character ("
) is stored. string "vector"
The ☆ mark inserted inside indicates that this vector character is the normal character 2.
This is padding for digit alignment because it has a digit width equal to the character.

The one-character display control section 12 supplies each character read from the text buffer 13 to a raster character output section 14 when it is a normal character, and supplies it to a vector character output section 15 when it is a vector character and is not selected. If a vector character is selected, it is supplied to the raster character padding output section 16.

The raster character output unit 14 outputs the character code of the supplied normal character to the raster character expansion unit 1 of the character expansion unit 17.
8 and develops it into a dot image. The vector character output section 15 supplies the supplied character code of the vector character to the vector character development section 19 of the character development section 17, and in this case develops it into a dot image twice the size of the normal character. The raster character padding n output section 16 converts the supplied vector character into a normal character, and further supplies the ☆ mark added to this vector character as a blank space for the normal character to the raster character development section 18, which develops it into a dot image.

The raster character development section 18 develops the supplied character code of the normal character into dot image bitmap data and displays it on the display 20, and the vector character development section 19 expresses the character code of the vector character in vector data. The vector character is expanded to a digit width including the ☆ mark added to the vector character, developed into dot image bitmap data, and displayed on the display 20. The above character expansion part 17
is expanded so that unselected characters are normally displayed and selected characters are displayed in reverse video.

FIG. 3 shows a flowchart of the above character string display processing.

In the figure, in step 30, information on one character is read from the text buffer 13, and in step 31, it is determined whether this character is a normal character or a vector character. In the case of normal characters, raster character expansion is performed in step 32, in the case of vector characters, it is determined in step 33 whether this character is selected, and if it is not selected, vector character expansion is performed in step 34, and if selected, step 35 performs raster character expansion with blank padding.

After executing steps 32, 34, and 35, it is determined in step 36 whether or not all characters have been output. If not, the process returns to step 30, and if it has been completed, this process ends. do.

As a result, when a vector character string that is displayed overlapping a normal character string as shown in FIG. 4(A) when not selected is selected, the vector character becomes normal as shown in FIG. 4(B). It is converted to a character, padded with blanks and displayed in reverse video to have the same character width as the vector character. As a result, the selected vector character string is displayed with the same digit width as the actual display or printed image, and the display response is good and editing operations can be performed smoothly.

[0019]

[Effects of the Invention] As described above, according to the selected vector character display method of the present invention, the vector character string selected during editing can be displayed close to the actual display or printed image, and smooth editing operations can be performed. This is extremely useful in practice.
