[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shading pattern creating apparatus.

[0002]

2. Description of the Related Art In a conventional shading pattern creating apparatus, various fonts having various shading patterns of each character are created in advance, and these fonts are stored in a font file of a storage device together with ordinary character fonts for control. When the data to output the font with the shading pattern is input from the terminal, the font of the specified character with the specified shading pattern is extracted from the font file and sent to the output display device for display. There is.

On the other hand, in a printer device that has a font in a memory and prints it, it is general to read font data byte by byte and send the data to a printing (control) device. That is, 1 font data
A process of reading out bit by bit and sending it out to the printing (control) device is not normally performed. This is because doing so causes the problems that the hardware becomes expensive and the processing speed becomes slow.

[0004]

However, in the above-mentioned conventional shading pattern creating apparatus, the shading pattern must be created in advance, and there is the inconvenience that the creation work takes time and time, and the shading pattern is created. A large amount of memory is required for abundant collection, which is inevitably expensive.

On the other hand, in the method of reading the font data byte by byte and sending the data to the printing (control) device, as shown in FIG. 7, in the character font, the horizontal width of one character is an integral multiple of bytes. If set to (1 in FIG.
(6 bits = 2 bytes), although no particular problem occurs,
When you want to shade a specified area (x, y, w, h) with a shading font as shown in (A),
When the area width w is not an integral multiple of bytes, FIG.
Or the shading area overflows the specified area,
There is an inconvenience that a part is missing as shown in FIG.

The present invention has been made under the above circumstances, and an object thereof is to produce a relatively inexpensive shading pattern capable of obtaining a high quality shading image by shading an area as specified. To provide a device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 schematically shows the configuration of a shading pattern creating apparatus 10 according to an embodiment.

This shading pattern creating apparatus 10
Is a control terminal 12 for inputting data instructing the type, position, size, etc. of shading to be created, and a plurality of types of shading pattern fonts for starting and shading pattern fonts for continuation are stored in advance. A storage device 14 as a storage unit, and a shading development area instructed based on data input from the control terminal 12 according to a control program described later,
A CPU 16 as a creating means for creating a shading pattern by adjusting the position where the shading pattern font for starting is placed, the type of the font, and the area where the shading pattern font for continuation is placed.
And a printer 18 as an output unit that outputs the created shading pattern.

More specifically, the control terminal 12
The keyboard 20 is used by the operator to perform an input operation, and the input circuit 22 is provided that creates data for instructing the type, position, size, etc. of shading created in response to the input operation and notifies the CPU 16 of the data.

A so-called ROM is used as the storage device 14, and the storage device 14 has a structure shown in FIG.
The shading pattern font for continuation shown in Fig. 3 and the shading pattern for start shown in Fig. 3B.
The pattern font is stored with the character font. EPROM or EEPROM is used as the storage device 14.
Of course, it is also possible to use.

The printer 18 prints out the shading pattern created by the CPU 16. For example, a dot printer, an ink jet printer, a laser printer or the like can be used. A display output device such as a liquid crystal display device or a CRT display device may be used as the output means instead of the printer 18.

Each of the above-mentioned components is connected via a system bus to C
Although not shown in the figure, the ROM is connected to the PU 16, and a ROM that stores a control program corresponding to a flowchart described later in advance or a RAM that functions as a work area
However, it is actually connected to the CPU 16 via the system bus.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. 2 showing the main control program of the CPU 16. Here, the case of drawing the shading of the pattern shown in FIG. Further, the start coordinates for expanding the shading (the upper left coordinates of the expansion area (short form)) are (x ₀ , y ₀ ), and the expansion height h ₀ is 8
The value of the width w _{0 to be} expanded by dots is set to 16 to 23.

At step 100, the operator
The board is operated and the shading pattern is changed from the input circuit.
Turn type (here, stored in advance in the storage device 14
Shading (pattern shown in FIG. 5A)
The data (x ₀, Y₀, W₀, H₀)But
When input, each parameter x, y, w, h
x₀, Y₀, W₀, H₀Rewrite

At the next step 102, it is judged whether or not h = 0. Here, since h is h ₀ , that is, 8, the determination in step 102 is denied and step 10
Proceeding to step 4, it is determined whether w ₀ for developing shading is divisible by 8. Here, since w ₀ is 16 to 23, if it is other than 16, it cannot be divided by 8, so this determination is denied and the routine proceeds to step 106. On the other hand,
When w ₀ is 16, it is divisible by 8, so step 11
The process proceeds to ₀ , and the continuation pattern font shown in FIG. 3A is set at the coordinate (x, y), here the shading start coordinate (x ₀ , y ₀ ).

In step 106, the designated coordinate x ₀ is corrected according to the remainder. This correction is [x _0- {8-M
OD (w ₀ , 8)] is calculated, and the value obtained by this calculation is set as a new x.

For example, when w ₀ = 17, the new x is rewritten as {x _0- (8-1)} = (x ₀ -7). Further, when w ₀ = 18, the new x is (x ₀ −
It is rewritten as 6). In the following, w ₀ is 19, 20, 2
The new x for 1, 22, 23 is (x ₀ −5),
(X ₀ −4), (x ₀ −3), (x ₀ −2), (x ₀ −)
It becomes 1).

In step 108, the starting font (see FIG. 3) is set at the coordinates (x, y) after correction in step 106.
As shown in (B), those prepared for the remaining value are selected).

In step 112, the width w for expanding the shading and the coordinate x are corrected. Wherein the correction of w is carried out by a _{{w 0 -MOD (w 0,} 8)} to the calculation of the value obtained by this calculation new w.

For example, when w ₀ = 16, the new w becomes (16-0) = 16 and virtually no correction is performed.
Also, w ₀ = 17,18,19,20,21,22,2
When 3, the new w is rewritten to 16.

The correction of the coordinate x is performed by setting (x + 8) as a new x. In the next step 114, w =
It is determined whether or not it is 0, and if there is a width to be developed, this determination is negative, so in step 112, the continuation pattern font is set to the corrected (x, y).

In the next step 118, w is set to (w-8),
After rewriting x into (x + 8), return to step 114,
The above determination / processing is repeated until the determination in step 114 is affirmed.

As a result, as shown in FIG. 4, only the number of times that the remaining width is satisfied (in this example, once when w ₀ = 16, otherwise 2 times when w ₀ = 17 to 23), The continuation font is set.

If the determination at step 114 is affirmative, the routine proceeds to step 120, where h is (h-8) and y is (y +
8), w is rewritten to w ₀ and x is changed to x ₀ , and the process returns to step 102, and thereafter, the above determination / processing is repeated until the determination in step 102 is affirmed, and the control operation, that is, the creation of shading is completed. As a result, the shading development is repeated a height h ₀ ÷ 8 (1 in this example) for developing the shading.

The shading font data set at each coordinate is processed by the print control unit (not shown) of the printer and printed out on the recording paper.

As described above, according to this embodiment,
Even if the width w for expanding the specified shading is not an integral multiple of bytes, the specified area can be shaded, and a high quality shading image can be obtained.

Further, since the shading pattern fonts stored in advance in the storage device 14 are only the shading pattern font for starting and the shading pattern font for continuation as shown in FIG. 3, It is sufficient to prepare a memory having a small capacity as the storage device 14, and there is an advantage that it is relatively inexpensive.

Depending on the shading pattern, the number (type) of starting fonts that must be prepared in advance can be reduced. For example, FIG. 5 (A)
In the case of the shading pattern as shown in FIG.
As shown in (B), since the start fonts for the remainders 0, 1, 2, and 7 are the same as the continuation fonts, the remainder 3, 3 as the shading pattern font for the start.
It suffices to prepare only the patterns shown in the figure for 4, 5, and 6. The font placement in this case is as shown in FIG.

[0032]

As described above, according to the present invention,
Shading can be applied to specified areas, and high-quality shading images can be obtained. In addition, the shading for starting
Since it is sufficient to store the pattern font and the shading pattern font for continuation, there is also an effect that a large capacity memory is unnecessary and the cost is relatively low.
