Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bitmap editing device for editing an image corresponding to bitmap data.

[Conventional technology]

2. Description of the Related Art Conventionally, some devices such as workstations and calculators are equipped with bitmap displays capable of displaying character patterns and graphics. Devices equipped with the bitmap display can use the bitmap editing function to create and edit desired character patterns and figures. For example, as shown in Figure 9, you can create a bitmap font with 9 rows and 9 columns,
You can edit the created bitmap font.

[Problem to be solved by the invention]

By the way, with the bitmap editing function of the above-mentioned conventional devices, when editing a bitmap font, it is necessary to edit each dot by deleting or adding, which takes time and increases the editing time. The work was getting complicated.

For example, if you want to delete the 5th column from the left of bitmap font 1 with 9 rows and 9 columns shown in Figure 9 (resulting in 9 rows and 8 columns), you can delete After deleting the 5th dot pattern, put the pattern in the 6th column in the 5th column, the pattern in the 7th column in the 6th column, etc.
... Rewrite the pattern in the 9th column in the 8th column, and
Column 1” pattern is the background pattern (for example, black and white 2
If it is a bit font that is black on a white background, it must be changed to all white). When performing this "rewriting", the pattern in the column to be "rewritten" must be deleted one dot at a time, and then the adjacent patterns must be referred to and rewritten one dot at a time. The bitmap font after this editing becomes bitmap font 3 shown in FIG.

Similarly, if you want to add another column to the pattern in the 5th row from the top of a bitmap font with 9 rows and 9 columns (in this case, it will be 10 rows and 9 columns), the 6th row will be added to the pattern in the 5th row. , the 7th line has to be changed to the pattern of the 6th line,... ] The Oth line must be changed to the new pattern of the 9th line.

As mentioned above, with the conventional bitmap editing function, when editing a bitmap font, it is necessary to delete and add dots one by one, making the editing work complicated.
Moreover, I had to spend a lot of time on editing work.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bitmap editing device that can easily edit images corresponding to bitmap data and can improve the processing efficiency of editing work. With the goal.

[Means to solve the problem]

In order to solve the above-mentioned problems, the bitmap editing device according to the present invention includes a specifying means for specifying a desired dot column or dot row and specifying editing contents for the specified column or row; The bitmap editing means updates the contents of the bitmap data in accordance with the specified editing contents for the dot row or dot row, and redisplays the image corresponding to the updated bitmap data.

[Effect]

In the bitmap editing device according to the present invention, it is possible to specify a desired dot column or dot row by the specifying means, and then delete the specified column 7 rows, or delete the specified column 7 rows from the adjacent column 7 rows. When editing contents to be added as an image are specified by a command, the bitmap editing means updates the bitmap data according to the specified editing contents and redisplays the image corresponding to the updated bitmap data.

〔Example〕

Embodiments of a bitmap editing device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a bitmap editing device according to the present invention. In the figure, the input unit] 1 consists of a keyboard and a mouse, and inputs desired commands by operating these devices to input bitmap font editing procedures (g collection operation commands), Also, by selecting a displayed command item, an editing operation command is input. The storage unit 12 includes a bitmap data storage area 12A, a real memory and a secondary storage device (not shown), and the pipmap data storage area 12A stores various bitmap data. The real memory and the secondary storage device store various data such as programs and commands based on flowcharts showing processing procedures to be described later. The display section 13 is composed of a bitmap display, and displays an image corresponding to bitmap data.

The central processing unit (CPU) 14 recognizes a manually input command, and if the recognized command is an editing operation command,
The command is passed to the font editor 5 to request editing.

When the font editor 5 receives an editing operation command from the CPU 14, it edits the bitmap data using the dot column and row operation section 15A.

At this time, the dot column and row operation section 1.5A is a position indicating the pitch I map data to be edited, the column or row of dots to be edited in the bitmap data (hereinafter referred to as the 7th row of dot column), The contents of the bitmap data are updated based on information indicating the editing contents for the seven rows of dot columns. The image corresponding to this updated bitmap data is redisplayed on the display section 13.

Next, the editing processing operation of the bitmap editing device will be explained.

First, in order to edit the image (bitmap font) corresponding to the bitmap data displayed on the display section 13, the user operates the input section 11 to enter an editing operation command (command), a desired dot column or line. If you specify CP
U14 recognizes the input command and issues an editing operation command (
command) to the font editor 15.

When specifying a dot column or row, the user moves a cursor that moves in conjunction with the movement of the mouse (not shown) to the position of the desired dot column and row 7, and then specifies either the dot I or column 7 row. Just do it.

Further, the dot column or row may be specified in one column or one row, or in multiple columns or rows.

By the way, in the dot column and line operation unit 15A of the font editor 5, as shown in FIG. If it is an editing operation command, the command is interpreted (step 101). Next, of the bitmap data to be edited,
If multiple columns or rows are specified, all columns or rows are recognized), and the bit to be edited depending on the interpretation result of the command for the recognized column or row. Update the contents of map data.

Here, the bitmap data to be edited may be bitmap data corresponding to the currently displayed bitmap font, and the dot column/row to be edited may be set to the position information indicating the cursor position and the column. The seven rows of dot columns obtained based on the information indicating one of the seven rows may be used. The data indicating the obtained seven rows of dot columns is held until a command is input manually. Note that when a plurality of columns or rows are specified, data indicating each dot column and seven rows obtained based on position information indicating the cursor position and information indicating one of the seven columns and rows is held.

Here, when the commands input by the user are commands 1 to 2 shown below, the respective editing processes are as follows.

That is: 1) 1)upliCate ColumnAdd selected column as its adjacent columnIf) Dupli
cate Row Adds the selected row as its adjacent row m) Delete Column Delete the selected column EV) Delete Row Delete the selected row (Steps 102 to 113)
).

If it is determined in step 100 that there is no dot column/row, and steps 104, 107, 110, and 113 are completed, bitmap editing is completed.

By the way, when the bitmap font currently being edited is in the 0th row and the mth column, if each of the above commands 1 to 2 is specified, the edited bitmap font will have the following results.

(2) The specified number of columns is 1 (and when the above command I is specified, the result is n rows and (m, +k) columns.

(2) When the specified number of rows is g and the above command (2) is specified, the result is (n + ρ) rows and m columns.

(2) When the specified number of columns is S and the above command (2) is specified, the result is n rows (m-s) columns.

(2) When the specified number of rows is t and the above command (2) is specified, the result is (n-, t) rows and m columns.

Here, k, 5 = (1, 2, 3, -N = m) N, t = (1, 2, 3, -N = n) Next, as shown in Figure 3, 1 row and m columns The bitmap editing process when editing the bitmap font 30 with 9 rows and 9 columns will be explained.

If the 5th column 1 from the left of the processing bitmap font 30 that corresponds to item (2) above is selected (in this case = 1), and the above command I is specified, the contents will be as shown in FIG.

If the fifth line from the top of the processed bitmap font 30 corresponding to item (2) above is selected, in this case l) = 1), and command n is specified, the content will be as shown in FIG.

If the fifth column from the left of the processing bitmap font 30 corresponding to the above (2) is selected (in this case 5=1), and the above command (2) is specified, the contents will be as shown in FIG. 6.

If the top five lines I of the processing bitmap font 3o corresponding to the above command (2) are selected (in this case t=1), and the above command (2) is specified, the contents will be as shown in FIG.

In FIGS. 3 to 7, each square corresponds to one dot, and the square "I" shown with diagonal lines means that it is clearly indicated as a bitmap font.

Note that when updating bitmap data, the dot column and row operation unit 1.5A performs this editing process, for example, when deleting the fifth column from the left of the bitmap font 30 shown in FIG. Target bitmap font 30
While referring to the bitmap data to be edited, transfer the dot pattern as it is without changing it up to the 4th column to an area different from the area where it is stored (for example, the work area), and transfer it to the 5th and 6th columns. The 6th column, 7th column, and 8th column contain the bitmap data to be edited, respectively.
Transfer the dot patterns in the 7th, 8th, and 9th columns.

In the embodiment, the settings are such that seven rows of dots are deleted or added based on the point (dot) indicated by arrow A in FIG. 3.

Then, the bitmap data in the work area may be overwritten in the area where the bitmap font 30 is stored. The bitmap font corresponding to the bitmap data after this change has the contents as shown in FIG.

Similarly, when adding a row of dots, for example, 5 dots from the left.
When a column is selected, the dot pattern is transferred to the work area as it is without any changes up to the 5th column, and the 6th column and 11th to 10th columns are transferred to the 5th column of the bitmap data to be edited. The dot patterns in the 9th to 9th columns will be transcribed.

In this case, the bitmap font corresponding to the changed bitmap data has the contents as shown in FIG.

Note that when a dot row is deleted or added, the same editing process as in the case of a dot column is performed.

Incidentally, in the above-described embodiment, each of the above commands is manually entered by inputting from the keyboard or selecting from a menu displayed, but as shown in FIG. It is also possible to display each command item corresponding to the above commands 1 to 2, respectively, and to select and input the item. In FIG. 8, 81 is Duplicate Co
It is a lumn item and corresponds to the above command I. 82 is a Duplicate Row item and corresponds to the above command H. 83 is Delete C
It is a column item and corresponds to the above command (■). 84 is a Delete, eRow item, which corresponds to the above command ■.

As explained above, according to this embodiment, when editing a bitmap font to be edited, the user can specify a desired dot column or row, and use the command By specifying (command corresponding to the editing content) once, the bitmap font to be edited can be edited.

Furthermore, by specifying a desired command after specifying a plurality of columns or rows, editing of each specified column or row can be performed at once.

〔Effect of the invention〕

As explained above, according to the present invention, the content of bitmap data is updated according to the specified editing content for a specified dot column or dot row, and an image corresponding to the updated bitmap data is created. Since the image is redisplayed, the image corresponding to the bitmap data can be easily edited, and the processing efficiency of the editing work can be improved.
