Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a contour line data processing device, and particularly to a contour line data processing device that divides the contour line of a character into a unique contour segment and a specific contour segment, and converts segment data regarding the specific contour segment into a character contour data processing device. This invention relates to a device that is stored in specific contour storage means separate from storage means.

[Prior art]

Recently, in order to print characters and symbols on printing paper or display them on a display, the outline font data of many characters such as characters and symbols are digitized and stored in non-volatile memory. The data is subjected to conversion processing such as enlargement and reduction processing to a desired size and thickness, and the converted outline font data is converted to dot data and printed using a laser printer or the like.

By the way, when creating outline font data for a large number of characters, each character of a predetermined size designed by a designer is digitized using an electronic scanner.

[Problem to be solved by the invention]

Therefore, the outline font data of the character stored in the non-volatile memory is based on the character designed by the designer, so for example, in Mincho kanji, the outline font data is commonly included as a part of the outline and has the same or similar shape. Specific outline portions that are supposed to be shapes, for example, accents indicated by pA in FIG. 3(a), scales indicated by pU in FIG. 3(b), and FIG. 3(C) according to the embodiment.
The writing brush is indicated by pO in Fig. 3 (cl), and pT is indicated in Fig. 3 (cl).
Tome indicated by , square scales indicated by symbol pK in Fig. 3(e),
There is a problem in that variations occur in the shape of specific contour segments such as the wing indicated by the symbol pH in FIG. 3(f).

Furthermore, as mentioned above, even though many characters include specific outline segments in common, outline font data is created for each character and these many outline font data are stored in the outline font memory. Therefore, there are problems such as the need for a large capacity outline font memory.

Therefore, the inventors of the present application stored segment data regarding specific contour segments such as accents, scales, and corner scales, and basic dimension data that defines the shape of these specific contour segments in a specific contour memory separate from the outline font memory. On the other hand, for each character, the outline font memory stores unique outline segment data that defines the shapes of unique outline segments other than the specific outline segments, and for the specific outline segments, a process is performed to obtain the identification flag and desired shape. The specific outline segment data of the specified character is read out from the outline font memory, while the specific outline segment data and basic dimension data are read out from the specific outline memory, and the shape of this specific outline segment is read out from the basic dimension data. It was proposed to specify the size using a magnification based on the size and size data.

However, since this magnification is always one type, there is a problem in that only similar shapes can be obtained for specific contour segments.

SUMMARY OF THE INVENTION An object of the present invention is to provide a contour data processing device that can reduce the memory capacity of a character storage means, and can also form a specific contour segment that is common to some of the contours of a large number of characters into a well-balanced shape. There is a particular thing.

As shown in the functional block diagram of FIG. 1, the contour data processing device according to the present invention processes a plurality of contour lines of a large number of characters of characters and symbols each consisting of one or a plurality of contour lines. a specific contour storage means for classifying a plurality of types of specific contour segments that are commonly included as a plurality of characters, and storing specific contour segment data that defines the shape of each of these specific contour segments in association with its type data, and for each of a large number of characters. , dividing the specific contour segment into one or more specific contour segments and one or more other unique contour segments, storing dimension data and type data defining the dimensions of the main specifications of the specific contour segment; Further, for the unique contour segment, the dimension data, type data, and unique contour segment data are read from the character storage means that stores the unique contour segment data representing the shape, and for the character specified by an external command. a reading means; and a reading means for reading out corresponding specific contour segment data from the specific contour storage means based on the type data read by the reading means, and selecting a plurality of specific contour segments constituting the specific contour segment based on the specific contour segment data and dimension data. data modification means for creating modified specific contour segment data representing the shape of the specific contour segment by performing a plurality of magnification conversion calculation processes so that the main specifications of each contour segment block have dimensions specified by the dimension data; and data synthesizing means for synthesizing contour data of the entire contour of the specified character using the unique contour segment data read by the reading means and the modified specific contour segment data created by the data modifying means. It's ours.

[Effect]

In the contour data processing device according to the present invention, the specific contour storage means includes a plurality of contours commonly included in a plurality of contours of a plurality of characters of characters and symbols each consisting of one or a plurality of contours. A plurality of types of specific contour segments are classified, and specific contour segment data defining the shapes of these specific contour segments and their type data are stored in association with each other. The specific contour segment is divided into one or more specific contour segments and one or more other specific contour segments, and for the specific contour segment, dimension data and type data that define the dimensions of its main specifications are stored, and the specific contour segment is divided into one or more specific contour segments and one or more other specific contour segments. Since unique contour segment data representing the shape of the segment is stored, the reading means reads the dimension data, type data, and unique contour segment data from the character storage means for the character specified by an external command. .

On the other hand, the data modification means reads corresponding specific contour segment data from the specific contour storage means based on the type data read out by the reading means, and configures a specific contour segment based on the specific contour segment data and dimension data. Modified specific contour segment data representing the shape of a specific contour segment is obtained by performing arithmetic processing of multiple magnification conversions so that the dimensions are specified by the main specifications or dimension data of each of the plurality of specific contour segment blocks. create.

Further, the data synthesizing means synthesizes outline data of the entire outline of the specified character using the unique outline segment data read by the reading means and the modified specific outline segment data created by the data modifying means.

[Effect of the invention] According to the contour data processing device according to the present invention, [Action]
As explained in the above section, specific contour segment data and its type data regarding each of a plurality of types of specific contour segments are stored in the specific contour storage means in association with each other, and the main specifications of the specific contour segments are stored in the character storage means. In addition to storing dimension data and type data that define the dimensions of the specific contour segment, unique contour segment data that represents the shape of the specific contour segment is also stored, so that the amount of data in the specific contour storage means does not increase. Since there is no need to store a plurality of types of specific outline segment data in the character storage means, the memory capacity of the character storage means can be significantly reduced.

Furthermore, the data modification means creates modified specific contour segment data that has been subjected to arithmetic processing of magnification conversion so that it has the dimensions specified by the dimension data, and the data synthesis means creates modified specific contour segment data from the unique contour segment data and this modified specific contour segment data. Since the outline data of the entire outline of the specified character is synthesized, it is possible to make the specific outline segment of the printed character into a well-balanced shape based on this outline data, and the data in the specific outline storage means can be made into a well-balanced shape. It can be applied to characters in multiple types of typefaces.

In addition, for a specific contour segment, multiple magnification conversion processes are performed so that the dimensions are regulated by the main specifications or dimension data of each of the multiple specific contour segment blocks that make up this segment. The shape of the contour segment can be subtly transformed for each segment block.

In addition, an input device 10 and a printing device 12 are connected to this bus 3°, and the input device IO is used to input various data necessary for data processing such as character codes and character size data supplied from the outside. The printing device 12 prints the bitmap data output from the dot data memory 28 using a laser printing method.

This data conversion control program includes a subroutine for reading out outline font data related to the input character code from the outline font memory 20, a scaling processing control subroutine for enlarging/reducing (scaling) the outline font data, and an outline font subjected to the scaling processing. It stores a short vector processing subroutine that expands data into short vectors, a Bezier curve function subroutine that generates a Bezier curve function, and a conversion processing subroutine that converts short vector processed outline font data into dot data.

By the way, a large number of characters such as kanji, hiragana, and various symbols in the Mincho font have an F accent J, which is indicated by the symbol pA in Figure 3(a), and an F accent J, which is indicated by the symbol pA in Figure 3(b). pU
"Uroko" indicated by the symbol pO in Fig. 3(C), "Fude Osae" indicated by the symbol pO in Fig. 3(d), "Tome" indicated by the symbol pT in Fig. 3(e), and F angle indicated by the symbol pK in Fig. 3(e). ``Tsu Loco'', Figure 3 (f
) is included as part of multiple contour lines of many characters, such as "bane" indicated by the code pH,

Therefore, regarding these six types of specific contour lines (hereinafter referred to as specific contour segments), specific contour segment data that defines the shapes of these basic specific contour segments is separately stored, and a desired contour segment data is created based on these specific contour segment data. It is possible to obtain modified specific contour segment data having a size of , and to synthesize this modified specific contour segment data with unique contour segment data representing the shape of a unique contour segment other than the specific contour segment.

As the basic specific contour segment data, starting coordinate data of a basic specific contour segment and a plurality of coordinate data defining the basic specific contour segment are stored. Further, the dimension data includes width (W), height (H), and length (L). However, only W and H are stored in the tome. In addition, the horn scales are divided into height (H] ~ H3) and length (Ll ~ L3) as shown in Figure 4 (e).
The basic dimension data of each type is stored. The starting coordinate data is the origin (0, O) of the xy coordinates, and each of the plurality of coordinate data following the starting coordinate data is relative coordinate data of a local coordinate system with the starting coordinate point as the origin. In addition, flag A, flag U, flag 0, flag T, flag K
, flag H is called a type flag.

On the other hand, in the outline font memory 20, each of a large number of characters is divided into one or more specific outline segments and one or more other unique outline segments in association with the code number of the character. For a specific contour segment, its type flag and dimension data that defines the dimensions of its main specifications (W, H, L, etc.) are stored, and for a unique contour segment, either the unique contour segment data representing its shape or the global coordinate system is stored. is stored as absolute coordinate data.

As shown in Table 1 below, this unique contour segment data stores start data, straight line data, Bezier curve (hereinafter simply referred to as curve) data, outline end data, and character end data for the unique contour segment, respectively. has been done. This start data consists of a start flag S and XY coordinate data that defines the starting point, the straight line data consists of a straight line flag L and coordinate data that defines the end point of the straight line, and the curve data consists of a curve flag B and coordinate data that defines the end point of the straight line. 1 control point Q

Character end flag indicating end! is stored.

Also, regarding specific contour segments, flag A: accent, flag U: scales, flag O: calligraphy, flag T: tome, flag to: corner loco, flag H: fly type flag, and specific contour segments. Dimensional data (w-A'·h) defining the size of is stored. That is,
Regarding the accent, flag A and three dimension data (w
-12・h) are stored in this order (see Figure 5(a)), and for scales, flag U and 3-dimensional data (w-1-h) are stored in this order (see Figure 5(a)). b)
), and for the brush size, the flag ○ and three dimension data (w-1-h) are stored in this order (see Figure 5 (C)).
)), for the tome, a flag T and two dimensional data (w-h) are stored in this order (see Fig. 5(d)), and for the horn scales, a flag and six dimensional data (
I! 1, 12, 13, hl-h2, h3), etc. (see Figure 5(e)).
A flag H and three dimension data (w-f-h) are stored in this order (see FIG. 5(f)). for example,
The outline data of the Mincho type kanji [Iku J shown in Figure 6 is as shown in Tables 2a and 2b below, the outline data is made up of unique contour segment data and 6 types of specific contour segment data such as scales, brush strokes, and accents. It is stored in font memory 2°.

(Margins below this page) Table 1 The text memory 24 stores text data (code string) supplied from the input device 10. The working memory 26 stores various calculation results processed by the CPU 16. The converted data is stored in the data memory 28.

(Margins below this page) Table 2b Next, the data conversion control routine performed by the data conversion control device 14 will be explained based on the flowcharts of FIGS. 7 to 10. In addition, the symbol Si (i=1
0, 11, 12...) are each step.

This control starts when the code data stored in the text memory 24 is read out, and the outline data of this code data is read out from the outline font memory 2o and stored in the working memory 26. The first flag included in the specific contour segment data is read out (SIO), and if this flag is included in the unique contour segment data (Sll-312/S13
:No), the segment data expansion processing fee wJ (see FIG. 8) is executed.

When this control is started and the all-read flag is "S" (S20: Yes), the start coordinate data is read (S21), and the transformation processing (scaling Process) is executed (S22), the start coordinate data after the scaling process is stored in the working memory 26 (S23), and the process returns to SIO. When the read flag is 1B (S20: No, S24: Yes), the curve data, that is, the coordinate data of three sets of the first control point, the second control point, and the end point, are read (S25), and the scaling process is performed. This is executed (S26), and the curve data after the scaling process is developed into a plurality of short vectors (S27), and the corrected outline data subjected to the short vector process is stored in the working memory 26 (S23). Also, if the read flag is “LJ” (S20/S24:N
o, S28: Yes), the coordinate data of the straight line is read out (
S29), scaling processing is executed (S30), and the linear coordinate data after the scaling processing is stored in the working memory 26 (S23). Furthermore, whether the read flag is
If it is neither “S”, “B”, or “L” (328
:No), error processing is executed (S31), and this control is ended.

On the other hand, if the read flag is a type flag indicating a specific contour segment (Sll-312: No, Sl
3: Yes), specific contour segment data conversion processing control (see FIG. 9) is executed.

When this control is started and the flag that has all been read is "A" (S40: Yes), the dimension data (w, (!, h) following flag A are read out in sequence (S41), and based on flag A Basic specific contour segment data of the accent, that is, a plurality of coordinate data and three basic dimension data of WL-H- are read out from the parts font memory 22 (S42), and enlargement/reduction processing is performed as follows. The modified specific outline segment data of the accent created by this process is stored in the parts buffer of the working memory 26 (S43).The accent is specified with one type of magnification.Therefore, the flag 0←B pOx← (POXx7)/L pOy←(POYXh)/H p 1 x= (PI XXjl') /LpI V
-(PI YXh)/H p2x←(P2XxA)/L p2y”-(P2YXh)/H Flag l←L p3x-(P3XxA)/L p 3 y←(P 3 YX h) /H Next, accent consists of one curve data including flag B and one straight line data including flag L, the number of data is set to "2" or counter C (S44), and this accent is specified in the unique contour segment data. In order to synthesize the contour segment data, each coordinate data of the specific contour segment data, which is a relative coordinate system, is converted into absolute coordinate data, which is an absolute coordinate system (S45). That is, the starting coordinate data of this accent is replaced with the final coordinate data of the outline data stored in the working memory 26 immediately before, and the starting coordinate data or the coordinate data changed by the conversion is added to each coordinate data of the accent. Executed by Kotoyonori.

Next, regarding the enlarged/reduced corrected specific contour segment data, the segment data expansion process or the counter C
The process is repeated the number of times (846 to 548), and then returns.

Also, if the read flag is "U" (S49: Y
es), dimensional data following flag U (w, 1, h)
are sequentially read out (S50), and the basic specific outline segment data of the scales and the three basic dimension data of WL-H are read out from the parts font memory 22 based on the flag U (S51), and the next enlargement/reduction processing is performed. The corrected specific contour segment data of the scales created by is stored in the parts buffer of the working memory 26 (S52).

Note that the scales are designated at one type of magnification. Therefore, flag 04-B p Ox= (P OXxIri /L p Oy= (P OYX h) /Hp 1 x←(
P IXX Iri /Lp 1 y -(P IYx

(S53), and after S45, the segment data development process is repeated for the modified specific contour segment data that has been enlarged or reduced by the number of times of counter C (846 to 848).

Also, if the read flag is "0" (S54: Y
es), the dimension data following flag 0 (w,!!,
h) are sequentially read out (S55), and based on the flag 0, the basic specific contour segment data of the brush stroke and the three basic dimension data of W-L and H are read out from the parts font memory 22 (356), and the next enlargement is performed. - The corrected specific contour segment data of the brush stroke created by the reduction process is stored in the parts buffer (S57). Incidentally, the brush strokes are specified at one type of magnification. Therefore, flag 0←B pox←(POXxI2)/ (L-W)poy= (
POYxh)/H p 1 x←(P IXXA)/ (L-W) p 1
y= (P I Yx h) /Hp 2 x” (P

4Yxh)/H p5x” (P5Xxffi)/L p5y←(P5Yxh)/H Flag 2←L p 6 x←(P 6XxIri /L p 6 y ←(P 6 Yxh) /H Next, the brush size is 2 Since it consists of one curve data and one straight line data, the number of data is set in r3J or counter C (358), and through S45, segment data expansion processing is performed for the modified specified contour segment data that has been enlarged or reduced. It is repeated as many times as counter C (846
~548).

Also, if the read flag is “TJ” (S59: Y
es), the dimension data (w, h) following the flag T are read out sequentially (S60), and the basic specific contour segment data of the toe and the two basic dimensions W-H are read out from the parts font memory 22 based on the flag T. data is read out (S
61), the corrected specific contour segment data of the tome created by the next enlargement/reduction process is stored in the parts buffer (S62). Note that the tome is designated with one type of magnification. Therefore, flag 0←B pOx-(POXXffi)/L pay←(POYxh)/W p 1 x←(P I XxIri /Lpty←(P

P4XXj7)/L p 4 y” (P 4 YX h) /Wp5x-(

), S45, and the segment data development process is repeated for the enlarged/reduced modified specific outline segment data by the number of times of counter C (846 to 548).

Also, when the read flag is "K" (S64: Y
es), dimensional data following flag K (I!1 to 13
, h1 to h3) are read out sequentially (S65), and the flag K(
Based on this, basic specific outline segment data of the square scales and six basic dimension data L1 to L3 and H1 to H3 are read out from the parts font memory 22 (366), and the next enlargement/reduction process (see Fig. 10) is carried out. The corrected specific contour segment data of the horn scales created by is stored in the parts buffer (S67). Note that the square scales are divided into three blocks: the first block consisting of curve 1, the second block consisting of curve 2 and straight line l, and the third block consisting of straight line 2, so each block can be enlarged or reduced. Processing is executed. First, in S80, the magnification SXI in the X direction is
The magnification SYI in the Y direction is determined so that LL and Hl in FIG. 4(e) correspond to i71 and hl in FIG. 5(e), so SXI = n 1 /Ll, SYI = h
1/old, respectively. In the next 381,
Based on these magnifications sxi and syl, the shape data of curve 1 is obtained as follows.

Flag 04-B p Ox 4-P oxxsx 1 p Oy-P 0YXSY 1 p lx + P lXX5X 1 p 1 y + P IYXSY 1 p2x + P2XXSX1 p2y-P2YXSY1 Similarly, in S82, the magnification in the X direction of the second block SX2 = 1 !2 /L2, magnification in Y direction 5Y2=
h2/H2, respectively, and in S83, based on these magnifications SX2 and SY2, the shape data of curve 2 and straight line 1 are determined as follows.

Flag 1←B p3x 4-P3XXSX2 p3y 4-P3YxSY2 p4 SY2 Similarly, in S84, the third block X-direction magnification SX3 = 73 /L3, X-direction magnification 5Y3 = h
3/H3, and in S85, based on these magnifications SX3 and SY3, the shape data of straight line 2 is determined as follows.

Flag 3←L p7x 4-P7XXSX3 p 7 y4-P 7 YXSY 3 Next, since the square scales consist of two curved data and two straight line data, set the number of data to "4" or counter C. (368), and the segment data expansion process is repeated for the number of times of counter C for the corrected specific contour segment data enlarged/reduced through S45 (
846-848).

Also, if the read flag is "H" (S69/Y
es), dimensional data following flag H (w, L h)
are sequentially read out (S70), and the basic specific outline segment data of the wing and the three basic dimension data of WL-H are read out from the parts font memory 22 based on the flag H (S71), and the next enlargement/reduction is performed. The modified specific contour segment data of the wing created by the processing is stored in the parts buffer (S72). It should be noted that the fly is specified at one type of magnification. Therefore, flag 0←B pox-(POXxA)/L 1)oy←(POYXh)/H p l x←(P IXXIri /L pty←(PIYXh)/H p 2 x -(P 2Xxf) /Lp2y← (P2

−(P 10XxI!,) /Lp 10 y= (P

Therefore, "5" is set in counter C as the number of data (S73), and after S45, the modified specified contour segment data that has been enlarged/reduced is subjected to segment data expansion processing or counter C. It is repeated the number of times (846-548). Note that when the determination in S69 is No, error processing is executed (S
74), this control ends.

Then, when the read flag is "*" (Sl 1
:Yes) Since the series of outline data has ended, the process returns to SIO to read the next outline data. On the other hand, when the flag is read or screams (Sll
:No, SI2: Yes), all the outline data has been completed, so the modified outline data that constitutes the entire synthesized outline stored in the working memory 26 for the input character is converted into dot data, and this The dot data is stored in the dot data memory 28 (S16), and this control ends.

As explained above, for the six types of specific contour segments 1 to 1 such as accents and scales, the type flags, the basic specific contour segment data related to the specific contour segments, and the basic dimension data are associated with each other and stored in the parts font memory 22. Memorize and outline font memory 2
0 stores the type flag and dimension data that defines the size of the shape of the specific contour segment for the specific contour segment, and also stores the unique contour segment data representing the shape of the specific contour segment, so the outline Only these six types of specific outline segment data are stored in the font memory 20, and the memory capacity of the outline font memory 20 can be significantly reduced.

Furthermore, modified specific contour segment data is calculated using a magnification based on the basic dimension data so that the dimensions of the shape of the specific contour segment are the specified dimensions, and the modified specific contour segment data and unique contour segment data are combined. Since modified outline data that forms the entire outline of the specified character can be obtained by composing them, specific contour segments of the printed character can be made into a well-balanced shape based on this modified outline data, and the part The data in the font memory 22 can be applied to multiple types of characters.

It should be noted that common outline parts of Mincho kanji or common outline parts of various typefaces such as Gothic fonts other than "accent", "scale", "fude osae", etc. used in the above embodiments are identified as specific outlines. It can also be a segment.

Note that it is also possible to store the outline font memory 20 and the parts font memory 22 in the same ROM.

Note that it is also possible to use the serif parts of alphabetic characters such as English and French as several types of specific outline segments.

It goes without saying that the present invention can be applied to various electronic devices such as printers, facsimile machines, and display devices that store characters such as letters and symbols as outline data.
