Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing device provided as one function of a workstation, a personal computer, a word processor, etc., and more particularly to a device for drawing a desired figure according to input coordinates.

[0002]

2. Description of the Related Art In a personal computer, a word processor or the like, in order to arbitrarily create an image, especially a figure and the like together with a document, a coordinate input means such as a pen or a mouse is used to arbitrarily operate on a display screen. Then, a function of drawing a desired figure, that is, a drawing device is provided. Further, the drawn figure can be arbitrarily erased in the same manner.

For example, the coordinates of an arbitrary point on the display screen are
Inputting is performed by using the pen or the mouse which constitutes the above-mentioned coordinate inputting means, and a line or a curve or a rectangular state is drawn between at least two coordinate points of the input coordinates, or 2
I draw a circle or an ellipse between the points. In addition, by sequentially drawing coordinate points that are continuously input, free drawing, that is, freehand drawing is possible.

Conventionally, when drawing a figure on the screen by operating a pen or the like, in addition to selecting the type of line, for example, the width of the line and the type of line (line type) such as a broken line and a solid line, colorization is performed. With that, it became possible to select colors. For example,
In Japanese Patent Laid-Open No. 2-121072, a pen number of a plotter and a color signal corresponding thereto are input in advance, a pen number is selected and a figure is drawn on the screen, whereby the figure can be drawn in the selected color. A CAD system is presented.

Further, in Japanese Patent Laid-Open No. 4-177518,
A switch for selecting black, red, blue, and green is provided on the pen itself for selecting a color to be drawn, and a color drawing device having a configuration capable of drawing with the color selected by the switch is specified.

Further, in Japanese Patent Laid-Open No. 7-56911,
It is described that the pen input coordinates are immediately converted into the coordinate position on the created document, and the line type and thickness of the drawing data can be arbitrarily selected and displayed on the screen.

[0007]

In order to select a color with a pen in a conventional drawing apparatus which is an image processing apparatus, Japanese Patent Laid-Open No. 2-121072 discloses a pen number and a color signal corresponding thereto in advance. It was necessary to confirm the number of colors set in the pen number by selecting the pen number after inputting in advance. In addition, JP
In the one described in JP-A-177518, in order to select the color of the pen, the selection switch provided on the pen itself,
Although black, red, blue, and green can be easily selected, other line attributes, that is, line width and line type, cannot be selected at the same time when the color is selected.

Further, in the technique disclosed in Japanese Patent Laid-Open No. 7-56911, the type and thickness of a line for drawing a figure can be arbitrarily changed, but the setting needs to be set each time immediately before drawing a desired figure. It was

As described above, in the case of drawing a figure using a pen or the like, the color of the line is selected in the colorization, and at the same time, the type of the line and the mode in which the line is drawn, for example, circle, ellipse,
Although it is necessary to select straight lines, curves, freehand, etc., it is necessary to select them in order,
The selection setting is also very troublesome.

Therefore, an object of the present invention is to preliminarily register commonly used colors, line widths, line types, shades and the like as attributes when drawing a figure, and instantly draw the attributes of the drawing in a visible form. It can be changed.

[0011]

In order to achieve the above object, the present invention provides a coordinate input means for inputting arbitrary coordinates and a desired image based on the coordinates input by the coordinate input means. In a drawing apparatus equipped with a graphic drawing means for drawing and a display means for displaying a graphic created based on the data drawn by the graphic drawing means, an attribute of the drawing data created by the graphic drawing means is used. A style registration means for pre-registering a line width, a line type, etc., a style selection means for selecting one of a plurality of styles pre-registered by the style registration means, and a style selection means Control means for causing the graphic drawing means to draw based on the selected style.

With this configuration, when performing desired drawing,
By pointing the input pen, which is the coordinate input means, to an arbitrary point on the display screen by the display means, a figure corresponding to the designated coordinates can be drawn. At this time, the width of the line to be drawn, the type of the line, the color to be drawn, and their shade can be registered in advance as various styles. Then, by selecting a desired style from the registered ones, it is possible to omit the operation of selecting the line width, the line type, the line color, etc. each time as in the conventional case.

Therefore, the plurality of styles obtained by the style registration means are displayed on the screen by the display means, and a mark for clearly indicating which style is the currently selected style is also displayed on the screen. The style of the selected style, that is, the width of the line, the type of the line, and the like can be easily recognized on the user side, and at the same time, another style can be selected or a new style can be registered.

In addition, a plurality of styles registered by the style registration means are added to the plurality of registered styles, and a mark immediately before the current style is displayed on the screen as a mark different from the selected mark. By doing so, it becomes easy to distinguish the selected style from the style immediately before, and the selection operation is facilitated.

When a desired figure is drawn by the figure drawing means on the screen of the display means, (1) a freehand tool, (2) an eraser tool, (3) a pen tool, and (4) a rectangle. Any one of the tool, (5) ellipse tool, etc. is arbitrarily selected, and the coordinate input means is operated to input coordinates to draw a figure of a predetermined shape based on the selected tool to obtain figure drawing data. create.

On the other hand, when drawing data is expanded on the display screen, drawing styles such as line width and type, and attributes such as color are individually registered by the style registration means as needed to draw an actual figure. Sometimes, drawing data is created based on the style selected by the selecting means from the registered style.

You can select the ellipse tool by pressing the key. A figure corresponding to the selection tool can be arbitrarily drawn. This selection can also be made by pointing the input pen 1 to an arbitrary position in each of the display areas 202 to 206.

Next, an embodiment of the present invention will be described with reference to the flowchart of FIG. First, it is necessary to first set the personal computer or the like to a drawing mode. Therefore, for example, the device is brought into the display state of the menu screen, and the graphic creation function is selected with the pen (S101).

In FIG. 5 (A), when the display area 200 showing the "graphic creation" function is designated with the pen 1 or selected with the direction keys on the keyboard in the menu screen, or in FIG. 5 (B).
As shown in, the operation is performed by the function key on the keyboard 5 corresponding to the “graphic” display area 201 on the display screen, or the display area 201 is operated by the pen (pen down).
By doing so, the drawing mode is set.

As described above, when the "drawing" function is selected and the drawing mode is entered, the current drawing style and drawing tool are displayed (S120). Here, the style is a generic name in which line attributes for drawing, for example, line width, line type, color, shade, etc. are selected and set. It eliminates the need to select the shades each time. For example, as shown in FIG. 7, the line width can be arbitrarily selected from extra fine lines, silk lines, double lines, thick lines, extra thick lines, and the like. In addition, a solid line, a broken line, a one-dot dashed line, or a two-dot dashed line can be selected as the line type. And black, white,
Green, blue, red, yellow, cyan, and magenta can be arbitrarily selected. Furthermore, as the shade, 100%, 90%, 80
%, 70%, 60%, 50%, 40%, 30%, 20
%, 10% can be selected.

That is, conventionally, after selecting one of the above-mentioned tools, it is necessary to select the line width, the line type, the color, and the shading each time, and the selection operation is very troublesome. In order to eliminate this trouble, in the present invention, on the user side, for a tool selected in advance,
By registering the above-mentioned attributes that accompany it as unique attributes in advance, it is possible to avoid troublesome operations.

In particular, when a figure is created, it is general that all the attributes shown in FIG. 7 are not selected and created, and it is created under a predetermined condition. It is possible to avoid troublesome operations such as selecting again.

Therefore, it is the current situation that the style is not registered immediately after the power is turned on or the first figure creating function is activated. Also, since the drawing tool is not selected, the most frequently used style is set as the standard style beforehand, and line width: thin line, line type: solid line, color:
Black and tint: It is registered as 100%, and this will be selected with priority. Figure 6 shows the display example.
(Or see FIG. 8).

As for the drawing tool, assuming that the freehand tool is selected, the drawing tool is displayed and activated as shown in FIG. 6 (or FIG. 8). In addition, the current item mark 210 indicating that the currently used style is the standard style is displayed in the status item.

When a graphic is drawn with the above-mentioned flah hand tool, the drawing with the flare hand can be performed without performing the drawing selection in the next step S140.
Immediately after activating the figure creation function, the drawing tool is specified as a freehand tool. When this freehand tool is used, the input coordinates by the operation of the van 1 on the screen are immediately converted into the coordinate position on the created document and displayed on the display screen 81 of the display means 8. At the time of this display, the drawing style currently used (currently standard) is expanded and displayed on the screen (S141).

Next, when the drawing tool is changed, the drawing tool is selected again in step S146.
Move to 0. This change is transferred by operating the change key of the drawing tool. This is, for example, "change" as displayed in FIG.
By operating the function key 51 of the keyboard 5 corresponding to the display area 208 or the instruction with the pen 1, the tool selection state is set, and the display shown in FIG. 6 is performed.

Therefore, description will be given when each drawing tool is selected. The eraser tool is selected by operating the portion corresponding to the display portion 203 with the pen 1 or operating the corresponding function key. Then, when this tool is selected, eraser display is displayed in place of the freehand display in the tool item, and the display screen state of FIG. , For the displayed drawing data, the input coordinates by the operation of the van on the screen are immediately converted into the coordinate position on the created document and erased. At the time of this erasing, only the line width is used as the attribute of the currently used style, and the style is expanded and erased on the screen (S142).

When the pen tool is selected,
With the pen, one point on the screen is designated by pen down and pen up, and the other point is designated by the pen, thereby drawing a straight line connecting these two points. In this case, the drawing style currently used is expanded and displayed on the screen (S143).

When the rectangle tool is selected, one of the four corners of the rectangle is pointed to by the pen and moved (drag) while being bent down, and when the diagonal point is reached, the pen is moved up and the rectangle can be drawn. . Further, the drawing style currently used is expanded and displayed on the screen (S144). In addition, when the ellipse tool is selected, pen down at one end of the ellipse, then drag toward the opposite end to draw an ellipse, expand it on the screen in the currently used style, and display it. (S145).

Next, the case of changing (selecting) or registering the drawing style according to the present invention will be described. Therefore, in step S147, the style change key for selecting the drawing style is operated. As a result, in step S122,
You can select (change) a style or register a new style. Therefore, for example, "change" 208 in the area which is always displayed on the display screen of the display means 8 is displayed.
By operating the portion corresponding to, the display of FIG. 6 and the like is performed. Then, when registering a new style, FIG.
"New style" display section 207 displayed on the screen in
Press the function key corresponding to. For this, the display unit 207 may be designated by the pen 1.

At this time, as shown in FIG. 9, one style area different from the standard style is added on the screen. Here, the line width, line type, color, and shade can be sequentially selected. For example, when setting the line width, by pointing the line width item 221 with the pen 1, the types of selectable line widths are displayed. From this displayed, an arbitrary line width can be selected by designating a desired line width with a pen, and the line width is displayed. Similarly, the line type, color, and shading can be arbitrarily selected by pointing the display area of the item with the pen 1 (S125).

When the arbitrary selection of the attribute relating to the style is completed, whether or not to register the style is determined next. When registering, the style name area 22
By giving a registration name to 2 (example style 1), style 1 is registered (S130). If this style is not registered, the style name is registered as blank as a temporary style (S12).
7).

Next, an item indicating the state of the style table is marked with a current mark ● indicating that it is currently used (selected) (S128). Here, if you registered in Style 1,
A current mark ● is attached to the status item of the style 1 (see FIG. 10).
(Refer to (A)), and when used as a temporary style, the blank state item of the style name is marked with a current mark (see Fig. 10 (B)). In addition, the previous style is the standard style in the present case, so the previous status mark is marked in the standard status item.
Is added (S129).

Thereafter, the drawing tool is selected and S14 is selected.
0, when a figure is drawn with each selected tool as described above, the figure is drawn with the currently selected style (S1
41, S142, S143, S144, S145).

Next, the case of selecting a desired style from a plurality of pre-registered styles will be described. That is, when the key for changing the style is operated, the process proceeds to step S122. First, FIG. 10 (A)
When the temporary style is similarly registered after the style 1 is registered as described above, the state shown in FIG. Such a state is stored (registered) in the RAM 22 as described above. When a change key or the like for changing the style is operated, the contents stored (registered) in the RAM 22 are read out and displayed on the display screen 81 of the display means 8. This display state is shown in FIG.
(A).

When selecting the style 1 in the display state of FIG. 11A, the style 1 is selected by pointing the display area 223 of the style name "style 1" with the pen 1 (S131). ), The status item of “Style 1” is marked with the current use mark ● 210 (S128), and the status item of the previous temporary style whose style name is “blank” is marked with the previous use mark ◯ 211. This state is shown in FIG. By simply selecting the drawing style in this manner, the attributes of the line are also selected at the same time, and the time and effort for selecting the line width and type, which are the attributes, each time are saved.

Thereafter, the drawing tool is selected (S14
0), when a figure is drawn with each selected tool, the figure is drawn with the currently selected style (S141, S14).
2, S143, S144, S145).

Next, as shown in FIG. 11B, the current drawing style is "style 1" and the immediately preceding style is changed from the temporary style to the "standard" style. To do. When returning to the standard style, the standard style is selected by pointing the standard display area 224 of the style name with the pen 1 (S132). As for the drawing style display, the current style becomes the standard style.
With 10 (S128), the style just before is style 1
Therefore, the last-used mark ○ 211 is attached to the status item of “style 1” (S129), and the style whose style name is temporary until now is “blank” is automatically disappeared (Fig. 11 (C)). Although this temporary style name will be automatically deleted, it will be retained during the drawing mode and a new temporary style will be registered separately. You may make it disappear at a stage.

Next, as shown in FIG. 11C, when the current style is "standard" and the immediately preceding style is "style 1", a description will be given of returning to the immediately preceding style. When returning to the immediately preceding style, the "style 1" is selected by pointing the display area 223 of the "style 1" marked with the mark immediately before the style name with the pen 1 at Ben 1 (S133). Since the selected style is style 1, as shown in FIG. 11 (D), the currently used mark ● 210 is added to the status item of “style 1” (S128), and the immediately preceding style is standard, so “standard” A last-use mark ◯ 211 is attached to the status item.

Thereafter, the drawing tool is selected and S14
0, when a figure is drawn with each selected tool, the figure is drawn with the currently selected style (S141, S14
2, S143, S144, Sl45).

In the above-described embodiment, the pen 1 which constitutes the coordinate input means is used to input the coordinates for drawing, but by using the mouse or the like to input the coordinates, You can also draw. In short, the means for inputting coordinates is not limited to the pen 1,
Of course, other means such as a mouse can be used.

[0060]

According to the present invention, since it is possible to assign a plurality of types of lines of a figure drawn on the display screen,
When drawing different styles, you can instantly draw different styles.

Therefore, it is possible to save the trouble of selecting again the width and type of the line which are the attributes of the line for drawing. Further, since it is possible to register any drawing style and select any of the registered drawing styles, it is not necessary to select the above-mentioned line attribute again.
