Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing device and method that can sequentially draw figures, characters, images, etc. composed of a plurality of partial figures on a display.

[Conventional technology]

As described in Japanese Unexamined Patent Publication No. 62-49477, a conventional device, for example, when creating a figure with a face as a target object, generates several types of partial figures such as eyes, nose, etc. that constitute part of the face. There is a drawing device that can create images of various shapes of faces by appropriately combining these partial figures.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not give particular consideration to the drawing order when a plurality of partial figures, two images of characters, etc. are combined and drawn in an overlapping manner. That is, the partial figures are drawn in the order in which they are selected.

In this case, for example, if you are trying to draw a "human face",
First, select "Face shape J" and then select "Hair style", then the partial figures of "Face shape" and "Hair style" will be drawn in the selected order.
A part of the "hair style" overlaps a part of the "face shape", and the "face shape"
There was an inconvenience that unnecessary lines were drawn in some parts of the image.

An object of the present invention is to create an order that is suitable for the object to be drawn, regardless of the specified drawing order, when a large number of partial figures are prepared for composing a certain figure to be drawn. An object of the present invention is to provide a graphic drawing device and method that can draw images according to the specifications.

[Means to solve the problem]

The above object is to provide a storage means for storing partial figures having drawing order determination rules for drawing a certain figure, a means for selecting and recalling partial figures from the storage means according to instructions from a user, and This can be achieved by providing means for determining the drawing order from the drawing order rules for a plurality of partial figures.

[Effect]

Partial figures constituting a certain figure are each stored in a storage means together with a drawing order rule. The means for searching and reading out these partial figures follows the user's instructions.
recall to the time storage area. The drawing order determining means determines the drawing order from the drawing order rule of the partial figures selected by the user and called up in the -time storage area, and causes the display device to draw in the determined order.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2(a) is a block diagram showing the basic configuration of the present invention. This device has a controller 200 that controls the entire device.
It consists of a keyboard, mouse, special switches, etc.
An input device 201 for creating and selecting figures, a display device 202 for displaying figures and images, and data for partial figures, which are small units of figures and images forming one unified figure, are stored. Partial figure storage memory 203 for
, a partial figure selection unit 204 that selects a partial figure necessary for drawing a desired figure from the partial figures stored in the partial figure storage memory 203, and a drawn partial figure memory that temporarily stores the selected partial figure. a drawing control unit 206 that draws the partial figures stored in the memory 205, the drawing partial figure storage memory 205 while comparing and determining the drawing order so as to form a desired figure on the display device 202; and a partial figure storage memory. Partial figure changing unit 2 that rewrites the contents in 203
Consists of 07. Further, the memory 205 may be shared with the memory 203 or may be provided separately and independently.

5 is an example of the data structure of a partial figure stored in the partial figure storage memory 203. The partial figure data includes a partial figure name column 101 in which an identification code for identifying each partial figure is entered, a drawing order column ↓02 in which drawing order judgment criteria for each partial figure is entered when drawing a certain figure,
It includes a drawing position column ↓03 in which the position when drawing these partial figures on the display device 202 is entered, and a drawing data column 104 in which the size and shape of each partial figure is entered.

Also, there are cases where you want to use one partial figure as part of multiple different figures. At that time, the drawing order of the partial figures often differs depending on the figure to be created.

That is, there are cases where it is desired to have multiple types of drawing orders for one partial figure. At that time, as shown in FIG. 1, the partial figure data includes a plurality of drawing order columns 102a,
102b, ]02c, . . . are provided and can be used depending on the figure to be created.

Furthermore, in the example of FIG. 1, the partial figure data includes data that serves as a criterion for drawing order, but the drawing order is stored in a separate memory section with the partial figure name attached, and the It may be read out in correspondence with the figure name.

FIG. 2(b) is a block diagram showing an example of the drawing control unit 206 in FIG. 2(a). The drawing control unit 206 draws the partial figure A stored in the drawing partial figure storage memory 205.
, B, C... have multiple drawing orders as explained earlier, it is possible to remember which drawing order should be used for which figure, and then follow the user's instructions to find the drawing order that matches the desired figure. A drawing figure specifying unit 2゜18 that instructs to read the drawing order information and a drawing order determination unit that compares the drawing order of the partial figures and instructs writing of data to the drawing partial figure storage memory and drawing to the display device. 209, a screen erasing section 211 that resets the display device 202 and returns it to a blank page (display screen erased), and a drawing section that sequentially draws partial figures on the display device 202 according to the judgment order instructed by the drawing order judgment section 2.9. It consists of 210.

FIG. 3 shows the 1
3 is a flowchart of a control program for creating two figures. The microprocessor unit (MPU) in the controller 200 operates each part according to this procedure.

This procedure and the operation of each part will be explained below.
Let us take as an example the case where partial figure data as shown in Figure 4(b) is stored in 03, and the partial figure is used to draw the shape of a human face as shown in Figure 4(a). I will explain.

The data in Figure 4 (b) is necessary when drawing the figure of a human face: "eyes", "nose", "mouth", "face shape", "hair" (
These are partial figures such as "back)" and "bangs", each of which has 1
It has one type of drawing order judgment standard data. The drawing order determination criterion is simply such that it can be determined that the smaller the numerical value entered in the drawing order column 102, the earlier the drawing order. It is assumed that the drawing position is a coordinate value based on the upper left corner of the display device 202.

First, the program started is the graphic information display step 30.
1, the graphic name registered in the drawing graphic designating section 208 is displayed on the display device 202.

The drawn figure designating section 208 includes a partial figure storage memory 203.
Information on what kind of figures can be created using a data group in the format shown in FIG. 1, and information on which drawing order to use for each figure are registered. In the above example, the drawn figure designation section 208 has the following information:
Assuming that only one piece of information "human face" is included, in step 301, "human face" is displayed on the display device 202.
The following message is output. If the above data contains multiple types of figures, such as "person's profile", "person's front-facing face", etc.
If each part shape has two different drawing orders for "side face" and "front facing face", then there will be two drawing order fields in the part shape data. The figure string information in the drawing figure designating section 208 becomes data indicating which column of the drawing order is used. This allows the user to view the display and select the type of figure to be drawn in the next drawing figure selection step 302. The partial figure information in the drawing data field 104 of FIG. 1 corresponding to the figure to be drawn next is stored in step 30.
3 to display on the display device 202. In the above example of "human face", "eyes", "nose",
Menu items such as ``1 mouth'', ``eyebrows'', ``face shape'', ``hair (back)'', and ``bangs'' are displayed. When the user selects a partial figure to be drawn in the partial figure selection step 304, the selected partial figure data is stored in the drawn partial figure storage memory 205 from the partial figure storage memory 203.
is loaded into. In step 306, the drawing order determining unit 209 checks whether partial figure data having the same drawing order information as the drawing data read in step 305 already exists in the drawing partial figure storage memory 205. is stored as is, and if there is one, it deletes the older one, stores the newly selected partial figure data, and outputs a message that the partial figures have been replaced.

In step 308, the screen erasing unit 2 of the drawing control unit 206
11 resets the display device 202 to a blank state. Next, in step 309, the drawing order determining unit 209
reads the rules in the drawing order column 102 corresponding to the figure to be drawn in the selected partial figure data stored in the drawing partial figure storage memory 205, compares and calculates the drawing order of each partial figure, and selects the drawing order that is faster. Drawing f! l1
Send to 1210.

In the above example, drawing is performed in order of decreasing numerical value in the drawing order column 102. In step 310, the drawing unit 210 reads the received partial graphic data and sequentially draws the data on the display device 202. Steps 303 to 310 are repeated to select and draw partial figures until the desired figure is drawn.

In the above example of drawing a "human face", if you follow the above process,
From the partial figure displayed in step 303,
) is selected, drawing as shown in FIG. 5(a) is performed in the processing up to step 310. Further, the process returns to step 303 and the "face shape 1" in FIG. 4(b) is selected, and the process is repeated again. When "hair 1" in FIG. 4(b) is selected for the third time, the display device The figure drawn in 202 is as shown in FIG. 5(b). That is, at this time, in step 305, the drawing partial figure storage memory 20
5 includes "eyes 2", "face shape 1", and "face shape 1" in Figure 4(b).
Three partial figure data of "hairman" have been loaded, and when reading the drawing order column of these three data, it is found that "hair 1" is drawn first, followed by "face shape 1" and "eyes". 2", so in step 309 the drawing order determining unit 209 sends data to the drawing unit 210 to draw "hair ↓", "face shape 1", and "eyes 2" in this order, and Figure (b
) will be displayed. As shown above,
With this device, the figures can be drawn in the desired drawing order no matter what order the partial figures are selected. In other words, "
This eliminates the need to overlay the face shape on top of the eyes and nose, resulting in a blank image and having to correct the drawing order. Further, after FIG. 5(b) is displayed, when the process returns to step 303 and selects "eye 1" in FIG. , "Eye 2" replaces "Eye IJ."

Then, in step 3↓O, the image is drawn as shown in FIG. 5(c). Then, in step 310, drawing is performed as shown in FIG. 5(C). Next, “Nose 1” in Figure 4(b)
, ``eyebrow 1'', ``upper bangs'', and 10 steps'', the figure in FIG. 4(a) is completed.

In the above example, a case has been described in which one figure is drawn, but it is also possible to draw a plurality of figures one after another by dividing the drawn partial figure memory 205 into a screen side and a figure side.

In the above, the case where a partial figure is selected from the partial figure memory 203 and a figure is drawn has been explained. This will be explained with reference to FIG.

FIG. 6 is a block diagram showing details of the partial figure changing unit 207 in FIG. 2(a). The partial figure changing unit 207
Graphic creation unit 601 for users to create arbitrary shapes
, a figure editing unit 602 for editing figures, a ranking changing unit 603 for changing the drawing order, a work memory 604 for creating or editing partial figures, and a part created or edited on the work memory. A registration unit 605 that transfers and writes graphic data to the partial graphic storage memory 203; and a display device 202 that transfers and writes graphic data to the partial graphic storage memory 203;
A display screen creation unit 606 that creates partial figure data to be displayed on the top, and a drawing unit 6 that draws figures and the like on the display device 202 according to the data created by the display screen creation unit 606.
Consists of 07.

FIG. 7 is a flowchart of a control program when data in the partial figure storage memory 203 is changed or newly created. Hereinafter, the user creates new "bangs" for the face shown in FIG. 8(a), that is, the face shown in FIG. The operation of the partial figure changing unit 207 will be explained by taking as an example the case where partial figure data of earrings are registered.

First, the figure of FIG. 4(a) is displayed on the display device 202,
Assume that it has already been drawn. When creating new partial figure data, that is, the data in Figure 1, first create the drawing data of the partial figure (104 in Figure 1), add information such as the partial figure name, drawing order, drawing position, etc. It is registered in the figure storage memory 203. Step 701~
In step 704, drawing data for the partial figure is created.

In step 701, the graphic creation unit 601 creates arbitrary graphic data on the work memory 604 in response to instructions from the input device 201. This may be dot data, text or graphic data. That is, the graphic creation unit 601 may be one that digitizes pictures and photographs using a scanner, or a character generator that creates characters and graphics. Furthermore, the drawing data of the partial figure data that has already been created may be read out from the drawn partial figure storage memory 205 onto the work memory.

In step 702, the graphic drawing data created on the work memory in step 70 is displayed on the display device 202 using the drawing unit 607. The user then performs step 7
At steps 03 and 704, desired drawing data is created by changing or modifying colors and shapes while looking at the displayed figures. In the example of creating FIG. 8(a) from FIG. 4(a), first, in step 701, the shape of the bangs is drawn using a spline, etc., and in steps 702 to 704, the desired shape is drawn. Fix it. Alternatively, the bangs shown in FIG. 4(a) may be modified to have the shape of the bangs shown in FIG. 8(a). At this time, Figure 4 (a), which had already been drawn,
) You can draw a new partial shape on top of the shape, so you can create a new partial shape while checking its size and position.

Once the bangs are created, the process returns to step 701 to create earrings in the same manner.

After creating new drawing data for a partial figure, information on the drawing order and position is added to step 2) in steps 705 to 709. In step 705, the display of the drawing order is prompted.

In step 706, the display screen creation unit 606 reduces the drawing data of the partial figures in the work memory 604 and the drawing partial figure storage memory 205, creates screen information for displaying them side by side with the drawing order information, and 607 displays it. In the above example where "bangs" and "earrings" are newly created, a screen like the one shown in FIG. 9 is displayed. While viewing this screen, the user changes or sets the drawing order information in step 707. In the example shown in Figure 9, the changed “bangs” has “8” in it, which is the same as the drawing order information before the change.
” is set. At this time, if the drawing order information is left blank, the partial figures become partial figures of unspecified order that are drawn in the order in which they are selected. In step 709, position information of the newly created partial figure is read. In this device, the display device 20 simply depicts the partial figure.
Since the coordinates on 2 are used as the drawing position (103 in FIG. 1), when drawing the drawing data of a partial figure, if it is drawn at a desired position in advance, it will be registered as is. Once the drawing data, drawing order data, and drawing position data of the partial figure are determined, in step 711, the created data is given a partial figure name by an instruction from the input device 201, and is stored in the partial figure storage memory 203.

As described above, the drawing order of partial figures can be changed or new partial figures can be created.

In the above embodiment, as shown in FIG. 1, the drawing order information of the partial figure is included in the partial figure data, but the drawing order information is drawn as a drawing order information table corresponding to each partial figure. It is also possible to use a device similar to the above, which is provided in the control unit 206, and which refers to a drawing order information table every time a partial figure is selected to draw it in a desired order.

〔Effect of the invention〕

According to the present invention, each time a partial figure is selected, it is possible to draw the figure in an order suitable for the image to be drawn, without having to instruct the drawing order or selecting parts while considering the drawing order. It is possible to improve the operability.
