Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides an area filling method for filling an arbitrary closed area with an arbitrary pattern by specifying one or more points in the area, and an electronic device. Related 6 [Prior Art] Conventionally, in electronic equipment having a page printer such as a laser printer or a display device such as a CRT display or a liquid crystal display as an output device, one point or a plurality of points in an arbitrary closed area can be detected using a mouse or the like. Some devices are known that have a function of filling an area with an arbitrary pattern by specifying it with a pointing device.

FIGS. 6(a) and 6(b) are diagrams showing examples of specifying starting points for filling. In FIG. 6(a), one point P1 within the area R is specified, and in FIG. 6(b), A case is shown in which four points P to P5 within region R are specified.

When a filling start point is specified as shown in FIG. 6(a) or FIG. 6(b), for example, a black dot (drawn image) is searched horizontally from the starting point, and a black dot (drawn image) is searched horizontally from the starting point. At the searched point, the black dot search is performed again in the opposite direction to detect a left and right section that can be filled, and this section is filled with an arbitrary pattern.Next, the left and right end points that have been filled are Using the same method for the vertical line as a reference, find the left and right sections that can be filled in and fill them in. Perform this process while shifting upwards and downwards in order, until black dots are created at the top and bottom ends. (drawing image) is detected, upward direction,
The filling process ends when it is no longer possible to shift further downward.

FIG. 6(C) is a diagram showing an example of the filling result obtained when the starting point is specified by either FIG. 6(a) or FIG. 6(b), and FIG. 6(a) , and FIG. 6(b), the rectangular frame F, that is, the closed area R surrounded by black dots, can be filled with a diagonal filling pattern, for example.

[Problem to be solved by the invention]

However, in the past, fonts, circles,
If a graphic or image such as a rectangle exists, or if shading has been input first, it may not be possible to fill in the closed area R, or only a part of the area within the closed area R may be filled. In some cases, the filling result was different from what was requested.

For example, as shown in FIG. 7(a), after the user inputs the outer frame F, if the user does not input any font 1 graphics, images, etc. within the closed area R surrounded by the outer frame F, for example, Assume that three starting points P1o1P11°P12 are specified. As shown in FIG. 7(b), the inside of the closed region R can be filled in with a predetermined pattern starting from these starting points P1°, Pll, and P12.

After that, the user uses font A. 9 yen AI, shading A
2, it is possible to obtain the desired filling result in which the metal body within the closed area R is filled in, as shown in FIG. 7(C), even if these objects exist within the closed area R. can.

On the other hand, as shown in FIG. 8(a), the user first inputs the outer frame F using the application, then inputs the font Ao1 yen At and the shading A2, and after that, the user inputs the outer frame F.
As shown in FIG. 8(b), with the intention of filling in the metal body within the closed region R surrounded by
, P1□, the starting points P1° and Pll are respectively font A. .

Since it is located on the circle A1 (that is, on the drawn black dot), the filling process will not start depending on the starting point P1° and Pll, and since the starting point P12 is located within the shaded area A2, , only a part of the area Ro within the shaded area A2 is filled in, resulting in the result as shown in FIG. 8(C). In this case, the closed area R as shown in FIG. 7(C) It is not possible to obtain the entire filling result.

In this way, conventionally, the font is placed within the closed area R.

The filling results are different depending on whether you specify the starting point for filling before inputting graphics, images, etc. or when specifying the starting point for filling after inputting fonts, graphics, images, etc. within the closed area R. There was a case. In addition, fonts, graphics,
When specifying a starting point for filling after inputting an image, etc., the filling result may vary depending on the specified position of the starting point for filling due to the effects of fonts, graphics, images, etc.

Such problems can be solved as shown in Figures 7 (a) to (C) and Figure 8 (
In addition to examples such as a) to (C), when you divide a circle into several parts like a pie chart, input numeric values 9 names, etc. in each divided area, and try to fill each divided area with an arbitrary pattern. In this case as well, if the numerical value 9 name etc. is input before each divided area is filled in, it may not be possible to fill in each divided area as desired in the same way as above. there were.

The present invention makes it possible to always obtain the same filling result as when fonts, graphics, images, etc. have not been input, even if fonts, graphics, images, etc. have been input within a predetermined closed area to be filled. The purpose of the present invention is to provide an area filling method and electronic device with good operability.

[Means to solve the problem]

In order to achieve the above object, the area filling method of the present invention sets priority of filling items for items such as fonts, graphics, images, etc. It is characterized by being expanded and output in the order of ranking.

Further, data for items such as fonts, graphics, images, etc. and data for fill items may be expanded into different buffers, and the data expanded in both buffers may be combined and output.

Further, the electronic device of the present invention includes a host machine that executes an application capable of creating image data, and an output terminal that performs predetermined drawing according to instructions from the host machine, and prior to filling instructions, fonts, graphics, etc. , is characterized in that when an item such as an image is input, control is performed on the output terminal side so that filling processing is performed without being affected by fonts, graphics, images, etc. in the closed area. There is.

[Effect]

In the present invention, for items such as fonts, graphics, and images, for example, if the fill item is set to the highest priority, items such as the font, graphic 1 image, etc. are input before specifying the fill. In this case, the filling data is developed first, so that by simply specifying any point in the closed area, you can fill in the closed area as desired without being affected by Font 1 graphics, images, etc. I can do it.

Alternatively, even if items such as font 1 graphics, images, etc. are input before specifying fill, the fill data and the data of items such as font, graphics, images, etc. are expanded into separate buffers,
By combining and outputting the data developed in both buffers, the closed area can be filled in as desired in the same way.

In addition, the output terminal side controls the filling of the font 1 in the closed area without being affected by graphics, images, etc. This reduces the burden of sorting work on the host machine side. can be reduced.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic diagram of an electronic device having a function of filling in an arbitrary closed area with an arbitrary pattern. Referring to FIG. 1, this electronic device is comprised of a host machine 1 and an output terminal 2 that performs predetermined drawings according to instructions from the host machine 1. As the output terminal 2, for example, a display device such as a CRT display or a printing device such as a laser printer is used.

On the host machine 1, an application capable of creating image data is executed. For example, as shown in FIG. 8(a), after the user inputs the outer frame F using the application, Ao, circle A1. Shading A
2 and then designate a point within the closed area R surrounded by the outer frame F and give a fill designation, and these processes will be executed.

Conventionally, when running such an application, the filling result differs depending on how points in the closed region R are specified, as described above, and the font A
There is a problem in that it may not be possible to obtain the same filling result as when a filling instruction is given before inputting 1 yen A, IN and A2.

Therefore, in the present invention, in order to solve such problems,
When a font, image, etc. is input prior to a fill-in instruction, control is performed so that the fill-in process is performed without being influenced by the font, graphics, image, etc.

By the way, as a way to realize the present invention, when a font, image, etc. is input prior to a filling instruction, the host machine 11111 (application side) changes the output order to the output terminal 2, font 1 graphics, One possible method is to control the filling operation so that it is executed before the image or the like. However, with this control method, there is a risk that the load of sorting work on the application side will be high. Therefore, in order to reduce the load on the application side, it is preferable to have the output terminal 2 perform the control.

FIG. 2 is a block diagram of a first embodiment of the invention. In this first embodiment, in the output terminal 21Pl, priority is set for each processing item to control the order, and the output terminal 2 side has one
Processes the data (print code, control code, graphic code, etc.) from the page buffer 3 and the host machine 1, and converts the data to be developed into the page buffer 3 into an intermediate format (hereinafter referred to as a disc libter). A conversion processing unit 5 to convert, a priority order table 4 in which priorities are set between each processing item, and a priority order table 4 when an output command (for example, a print command or a display command) is sent from the host machine 1. An expansion control unit 6 refers to table 4 and expands the bitmap to the page buffer 3 in order of priority processing items, and prints the data expanded to the page buffer 3 when an output instruction is sent from the host machine 1. An output control section 7 for outputting or displaying the output is provided.

Next, processing operations in the first embodiment having such a configuration will be described. When an application in the host machine 1 prints or displays output to the output terminal 2, the application sends the control codes of the output terminal 2 to the output terminal 2 in the order of input. The output terminal 2 performs control so that even if the control codes are input and sent in the order in which they were input, the same output result is always obtained regardless of the order.

That is, the conversion processing unit 5 of the output terminal 2 sequentially processes the data (print data, control code, graphic code, etc.) sent from the host machine 1 in the order of input, and converts all the data to be developed into the page buffer 3. Convert to disc libta.

FIG. 3 is a diagram showing an example of a disc libter converted in this manner, and FIG. 3 shows a disc libter as a result of converting font data. °In Fig. 3, the number of bytes of one disk scriber is, for example, 18.
It's a part-time job.

Next, the expansion control unit 6 of the output terminal 2 refers to the priority order table 4 as shown in FIG. 4, and performs bitmap expansion in this order. Bitmap development for the highest closed area filling is performed in the page buffer 3, followed by bitmap development in the order of graphic code development 1 shading development, image development, and font development.

In this way, by setting bitmap expansion for closed area filling to the highest priority, if a filling instruction is given before inputting fonts, graphics, or images, the input of fonts, graphics, or images will be In any case where a fill instruction is given later, the bitmap expansion for filling the closed area is always performed first in page buffer 3, regardless of the order, and graphics are stored in the closed area. ,
Even if there are IM calls, images, and fonts, it is possible to always obtain the same filling result without being affected by these during drawing. In other words, the filling bitmap is developed before the bitmap of fonts, graphics, images, etc. is developed, so even if there are other font data, graphic data, image data, etc., a single point is specified as the starting point for filling. The specified position may be any position within the closed area, and with such a simple operation, it is possible to always fill in the metal body within the closed area R as desired.

For example, even if inputs and specifications are made in the order shown in Figures 8(a) and 8(b), inputs and specifications are made in the order shown in Figures 7(a) and 7(b). Figure 7 (C) similar to when
You can always get results like this.

Note that the order of the priority table 4 can be registered and changed using a control code from the host machine 1. In the example in Figure 4, closed area filling has the highest priority, but if a control code is sent that gives the highest priority to graphics, for example, the priority in Figure 4 The priorities in the ranking table 4 can be changed.

By arbitrarily changing the priority order in priority table 4, you can specify that some graphics, shading, images, and fonts will be affected by closed area filling, while others will not be affected. It is also possible to do so.

FIG. 5 is a block diagram of a second embodiment of the invention. In this second embodiment, on the output terminal 2 side, there are two page buffers 13 and 14 for outputting one page.
A control unit 15 that controls bitmap expansion to the page buffer 13.14, and a control unit 15 that controls bitmap expansion to the page buffer 13.14, and a control unit 15 that controls bitmap expansion to the page buffer 13.14, and
A synthesizing section 16 is provided which calculates the logical sum (OR) of the bitmap data from the page buffer 13 and the bitmap data from the page buffer 14 and outputs the synthesized data when the bitmap data is read from the page buffer 13 and the bitmap data from the page buffer 14 respectively. It is being

In this embodiment, by preparing two page buffers 13 and 14, one page buffer 13 is used only for bitmap development for filling in closed areas, and the other page buffer 14 is used for graphics, fonts, and images. It can be used only for bitmap development of data, etc.

When using page buffers 13 and 14 as described above, bitmap development for fonts, graphics, and images is done in page buffer 14 even when a fill instruction is given after inputting a font or graphic 1 image. Since the bitmap development for filling in the closed area is performed in the page buffer 13 separate from the page buffer 14, it is not affected by fonts, graphics, images, etc.

After that, when an output instruction is sent from host machine 1,
The control unit 15 reads bitmap data from each of the page buffers 13 and 14, respectively.
The bitmap data read from 14 is sent to synthesis section 16.
The logical sums are taken, the results are combined, and the results are printed or displayed.

In this way, the same results as in the first example can be obtained in the second example as well. That is, for example, even if the inputs and specifications are made in the order shown in Figures 8(a) and 8(b), the inputs and specifications are not made in the order shown in Figures 7(a) and 7(b). It is possible to always obtain the same result as shown in FIG. 7(C).

〔Effect of the invention〕

As explained above, according to the area filling method of the present invention, the priority of filling items is set for items such as fonts, graphics, images, etc., and data of input and specified items is set. It is designed to be expanded and output in priority order, or data for items such as fonts, graphics, images, etc. and data for fill items are expanded into separate buffers, and the data is expanded to both buffers. Since the data is synthesized and output, even if fonts, graphics, images, etc. have been input within a predetermined closed area that should be filled, if these have not been input yet. It is possible to always obtain the same filling results as with the previous version, and the operability can be significantly improved.

In addition, in the electronic device of the present invention, when items such as fonts, graphics, images, etc. are input prior to a filling instruction, fonts within a closed area.

9 coats without being influenced by graphics, images, etc.

Since control for performing the blurring process is performed on the output terminal side, the load on the aggregation side can be reduced.
