Description

[Detailed Description of the Invention] [Summary] Regarding a drawing control method in a graphic editor etc., a specific color among a plurality of colors already drawn on the screen is
The purpose is to allow selective drawing with a specified color. When drawing an image with a specified color, it allows multiple colors already drawn on the screen to be repainted with the specified color. At least one of a repainting permitted color and a repainting prohibited color that prohibits repainting to a specified color is set, and a specific color is selectively repainted.

(Industrial Application Field) The present invention relates to a drawing control method in a graphic editor or the like.

[Conventional technology]

2. Description of the Related Art Conventionally, as a drawing control method for drawing an image in a specified color, a method is known in which drawing is performed in a newly specified color, regardless of the color already drawn on the screen.

[Problem to be solved by the invention]

However, with the above drawing control method, it is possible to leave a specific color among the colors that have already been drawn as is and change other colors to the specified color, or to specify only a specific color in a specific area. It was not possible to change the color.

For example, if you draw the trunk and branches of a tree in brown, and then try to draw green leaves around the tree, and you specify green as the color for the area containing the tree trunk and branches, the brown color of the trunk and branches will change. Parts of it will also be repainted green, and the tree trunk and technique parts will disappear.

Therefore, when leaving an area of a specific color, it is necessary to designate only the pixels of the part whose color you want to change one by one to specify the color, which makes the drawing work complicated.

An object of the present invention is to enable a user to selectively draw a specific color among a plurality of colors already drawn on a screen using a designated color.

[Means to solve the problem]

In the drawing control method of the present invention, at least one of a repainting permission color that allows repainting to a newly specified color and a repainting prohibited color that prohibits repainting of a plurality of colors already drawn on the screen is selected. Can be set.

[For production]

If a specific color drawn on the screen is set as a color that is allowed to be repainted, only the color that is set as a color that is allowed to be repainted is repainted to the specified color.

Furthermore, if a specific color is set as a color that is prohibited from being repainted, the color that is already drawn and is outside the color primary that is prohibited from being repainted is repainted to the specified color.

Therefore, since it is possible to selectively draw only a specific color or a specific color area outside the range, there is no need to draw carefully so as not to erase the already drawn color. Drawing work can be performed more efficiently.

〔Example〕

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

FIG. 1 is a configuration diagram of a drawing apparatus that performs drawing based on the drawing control method of the present invention.

In the figure, a mouse 1 is an input device for inputting figures, colors, etc., and when the mouse 1 is operated, the system RAM is
The drawing module 2 and control module 3 above start up.

The drawing module 2 draws a specified area in a specified color to create a drawing pattern. Kome drawing module 2
The drawing pattern created by is stored in the drawing pattern storage section 4.

Furthermore, prior to specifying a color, a repainting permitted color and a repainting prohibited color are set from among a plurality of colors already drawn on the screen, and these colors are stored in the repainting permitted color storage section 6 and the repainting prohibited color storage section. 7 respectively.

Colors set as repaint-permitted colors are repainted to the designated colors by the above-mentioned drawing module 2, while colors set as repaint-prohibited colors are not repainted and are stored as they are in the drawing pattern storage unit 4. Ru.

The control module 3 is a module that creates display dot pattern data from the drawing pattern created by the drawing module 2. The display data created by the control module 3 is written to a V-RAM (not shown) and then output to a display 5 such as a CRT.

Next, regarding the drawing process based on the drawing control method of the present invention,
This will be explained with reference to the flowchart in FIG.

First, in step Sl in FIG. 2, the presence or absence of an operation on the mouse I is detected, and it is determined whether any input operation has been performed on the image displayed on the display 5.

When the mouse 1 is operated, information such as the locus or color of the drawing pattern inputted by the mouse 1 is read in the next step S2.

Then, in the next step S3, the drawing pattern is updated based on this information.

Here, the contents of the drawing pattern update process will be explained in detail with reference to the flowchart of FIG.

When an input is made using the mouse 1, the drawing module 2 is activated and first determines whether or not a repainting permission color is set (FIG. 3, step S5).

If the repainting permitted color is set, in the next step S6, the color set as the repainting permitted color is repainted with a newly designated color. Then, the repainted drawing pattern is stored in the drawing pattern storage section 4 described above.

At this time, for example, even if the colors are in the area designated to be repainted, colors that are not set as repaint-permitted colors are not repainted, and those colors are stored as they are in the drawing pattern storage unit 4.

In this way, by setting a repaint permission color that allows repainting to the specified color when specifying a color,
You can selectively repaint only a specific color among multiple colors.

On the other hand, if it is determined in step S5 that no repainting permitted color has been set, the process advances to step S7 and it is determined whether or not a repainting prohibited color has been set.

If a color that is prohibited from being repainted is set, step S
Proceed to step 8 and repaint the colors other than the prohibited colors to the currently specified color. The repainted drawing pattern is then stored in the drawing pattern storage section 4 described above.

In this way, when specifying a color, by setting a color that is prohibited from being repainted, it is possible to leave an area of a specific color as it is without erasing it.

Further, if neither the repainting permitted color nor the prohibited color is set, the process advances to step S9 and no color repainting is performed.

When the drawing module 2 finishes updating the drawing pattern in this way, the control module 3 starts up and
The display update process of step S4 in FIG. 1 is executed.

In this display update process, the drawing module 2 creates display dot pattern data corresponding to the drawing patterns repainted in the currently specified color, and converts these display dot pattern data into the V -Write to RAM. Then, the data on the V-RAM is displayed on the display 5, and drawing is performed in the specified color.

Next, an example of drawing by the drawing control method of the present invention will be explained with reference to FIG.

FIG. 4 is an explanatory diagram when drawing a green leaf area around a tree.

In the following, when blue is drawn as the background color and brown is drawn as the color of the tree trunk and techniques, a case will be described in which the shaded area is drawn in green, leaving the colors of the tree trunk and branches intact.

In this case, the settings for the repainting permitted color and prohibited color are as follows.

This is a case where blue is set as the repainting permitted color and nothing is set as the repainting prohibited color, or a case where nothing is set as the repainting permitted color and brown is set as the repainting prohibited color.

In the former case, as a result of reading the display colors displayed on the display 5 at that time, the background color blue and the brown of the trunk and branches of the tree are read, and among these, the repainting permission color blue is changed to green. Can be repainted.

At this time, the brown parts corresponding to the trunk and branches of the tree are left as they are because they are not set as a color that is permitted to be repainted.

Similarly, in the latter case, the background color blue is replaced with green,
The brown part of the tree, which is set as a color that cannot be repainted, will be left as is.

This allows you to repaint while leaving a specific color within the specified area.

Next, after repainting the shaded area green as described above, we will explain how to draw a wider area including tree trunks and techniques, or specify green without specifying any area. do.

For example, if you set blue, or blue and green, as the color that allows repainting, but do not set anything as the color that prohibits repainting,
At this time, the blue, brown, and green colors displayed on the display 5 are read, and the blue portion or the blue and green portions that are set as repaint-permitted colors are repainted with green.

In this way, multiple colors can be set as repaint permission colors, so even when many colors are displayed on the display 5, you can select and specify multiple colors from among them. You can repaint it to a different color.

Further, in this case, since colors that are not set as repaint-permitted colors are not repainted, the brown parts corresponding to the trunk and branches of the tree can be left as they are without being erased.

On the other hand, if nothing is set as the repainting permitted color and brown is set as the repainting prohibited color, blue, green, and brown displayed on the display 5 are similarly read respectively. Then, all parts other than brown, which are set as prohibited colors, are repainted to green.

By setting a specific color as a color that is prohibited from being repainted in this way, it is possible to repaint an area of another color with a newly designated color without erasing that color. A plurality of colors can also be set for this repainting prohibited color.

As described above, according to the above embodiment, the display 5
You can select specific colors from the colors shown above and draw areas of those colors with the specified color, or leave areas of a specific color and draw areas of other colors with the specified color. You can also draw with .

Therefore, when drawing in a newly specified color, there is no need to draw with care so as not to erase the color displayed on the display 5, and the drawing work can be performed more efficiently.

〔Effect of the invention〕

According to the present invention, it is possible to repaint other colors with newly specified colors without erasing a specific color drawn on the screen, so graphic data etc. can be created more efficiently. .
