CONSTITUTION:Design data of a knit fabric are stored in data storage regions 32, 34, 36 as an internal data comprising one pixel corresponding to one loop. The aspect ratio is corrected by an affine transformation means 24 and the data are displayed on a graphic monitor 30. The input position of a stylus 16 is also transformed from internal data coordinates to the coordinates on the monitor by a coordinate affine transformation means and displayed on the monitor. Accordingly, the internal data in the data storage areas 32, 34, 46 are converted to a virtual image for the designer to enable the design on the data having corrected aspect ratio of loop.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to a knit paint system for designing knits. In particular, this invention uses the internal data that ignores the loop aspect ratio, displays the knit design data that has been corrected to the actual aspect ratio on the monitor, virtualizes the internal data to the designer, and corrects the loop aspect ratio. It relates to a system that can be designed for the specified data.
In this specification, a knitted fabric means not only a knitted fabric having a form such as a sweater but also a knitted fabric having no particular form.

[0002]

The applicant has proposed a system for designing a knitted fabric on a monitor (Japanese Patent Publication No. 3-21661). In this system, knitting data in the design process is stored in a frame memory, for example, one pixel is assigned to one loop, and organization data such as a pattern is stored in the color of the pixel. For example, if the degree of freedom of color is 256, then 256 types of data can be expressed for the loop knitting method. The type of color thread to be used is specified as an option, and is specified for each type of organization in the organization data. Further, in this system, the data in the frame memory after the design is converted into the data to be knitted by the knitting machine using the reference table or the like.

However, the loop of the knitted fabric has an aspect ratio (aspect ratio), and the loop is generally not square.
Therefore, the data displayed on the monitor will be different from the actual knit image. For example, a circle is displayed as an ellipse, the ellipse is further distorted or conversely displayed as a circle, a square becomes a rectangle, and an equilateral triangle becomes an isosceles triangle. Therefore, it becomes difficult to imagine the actual knitted fabric from the image on the monitor, and the design becomes difficult.

Next, the above-mentioned system lacks design tools. For example, patterns that often appear in knits include polka dots, repeating patterns, and straight lines, which the above system does not support. Therefore, these patterns are drawn with a stylus or the like. However, inputting a large number of polka dots in an environment in which circles are displayed as ellipses becomes a burden, and similarly it becomes difficult to repeatedly reproduce and input the same pattern. In the case of a straight line, it is displayed without correcting the aspect ratio, so it is difficult to imagine the actual inclination of the straight line from the monitor, and it is also difficult to draw a straight line with a stylus.

[0005]

The problems of the present invention are as follows. 1) Virtualize the internal data of the frame memory ignoring the aspect ratio of the loop to the designer, display it as if only the data of the actual aspect ratio exists, and add the design to this image. It is possible (claims 1 to 5). 2) It facilitates the design of patterns often used in knitting and eliminates the design burden (claims 3 to 5).

[0006]

According to the present invention, while design data of a knit is displayed on a monitor, the design data of the knit is stored in the frame memory without correcting the aspect ratio of the loop, and the data of the frame memory is stored by an external input means. In a knit paint system that was modified to design a knit, correct the data in the frame memory according to the aspect ratio of the loop and display the data from the aspect ratio correction means for displaying on the monitor and the external input means. , Means for displaying at the position where the loop aspect ratio is corrected on the monitor, and for inputting to the position where the loop aspect ratio is not corrected for the frame memory, are provided.

Preferably, the aspect ratio correction means is composed of affine transformation means. More preferably, with a means for storing a plurality of polka dots and reference points for these polka dots without correcting the aspect ratio of the loop,
By using the aspect ratio correction means to correct these polka dots and the reference point with the loop aspect ratio and display them on the monitor, and specify the position of the reference point for the data on the monitor Means are provided for copying to the data on the frame memory. Further, preferably, means for designating a repeat area in which the pattern is repeated a plurality of times for the data on the monitor, and means for designing a pattern for at least one unit in the designated repeat area are designated. Means for repeatedly copying the above pattern to the frame memory are provided for the repeat area. Further, preferably, for the data on the monitor, a means for designating two points and displaying a straight line between them, and a means for copying the designated straight line to the frame memory are provided.

[0008]

According to the present invention, the design data (internal data) of the knitted fabric on the frame memory is virtualized for the designer, and the internal data corrected (monitor data) according to the aspect ratio of the loop is displayed. In the internal data, for example, 1 pixel is assigned to 1 loop, and it is displayed on the monitor according to the actual aspect ratio of the knitted fabric. Data from an external input means necessary for design is input to, for example, coordinates (internal address) on the frame memory, and the monitor displays the internal address at coordinates (monitor address) corrected according to the aspect ratio. Alternatively, conversely, data from the external input means may be input as a monitor address, the monitor address may be converted into an internal address, and then input to the frame memory. As a result, the coordinates of the internal data and the external input are virtualized into the monitor data and the monitor address, and the design can be performed using the monitor data and the monitor address.

Typical patterns used for knitting are polka dots, repeating patterns (repeat patterns), and straight lines, which facilitate the design of these patterns. For example, in the case of polka dots, a plurality of polka dots and reference points of these polka dots are stored as internal data, and converted into monitor data and monitor addresses for display. If the position of the reference point is specified for the knitted fabric on the monitor using the monitor address, only the polka dots are copied to the frame memory. The data of the polka dot to be copied is the internal data, and the copy position is the internal address. In creating a repeat pattern, a repeat area is designated, the repeat area is displayed by a monitor address, and the repeat area is stored by an internal address. Next, a pattern for one unit is designed, stored as internal data, and displayed as monitor data. Then, the pattern is repeatedly copied to the repeat area and written in the frame memory as internal data. In a straight line design,
Specify two points for the monitor and approximate them with a straight line. These points and the straight line between them are stored as internal data and written in the frame memory as internal data.

1 to 10 show an embodiment, FIG. 1 shows a hardware structure of a knit paint system, and FIG. 2 shows details of a knit paint processing section. Note that the display in FIG. 2 and subsequent figures shows the hardware configuration of FIG. 1 implemented by software.

In FIG. 1, 2 is a main bus, 4 is a host CPU, 6 is a main memory, and 8 is a graphic CPU. As input / output, for example, a scanner 10, an external storage 12 such as a floppy disk, a hard disk or a magneto-optical disk, a digitizer 14 and a stylus 1
6, keyboard 18, etc. are used. Graphic CPU 8
Is connected to a graphic bus 20, and a group of frame memories 22 and work memories 23, an affine transformation processing unit 24, and a mesh mapping processing unit 26 are connected to the bus 20.
The data in the frame memory 22 is combined by the combining processing unit 28 and displayed on the graphic monitor 30.

The knitting data in the design process is stored in the frame memory 22 as internal data in which one loop has one pixel, for example. Similarly, polka dots, straight lines, repeat patterns, etc. in the creation process are stored in the work memory 23 in the internal data format. The affine transformation processing section 24 corrects the internal data according to the aspect ratio of the loop to obtain monitor data, and stores the correction result in another area of the frame memory 22. The affine transformation is the address (x, y)
Data of the address (ax + by + c, dx + ey +
f). Here, c and f represent offset terms and are used for offset correction between the display addresses of the frame memory 22 and the graphic monitor 30.
Further, when the coordinate x is converted into ax + by and the coordinate y is converted into dx + ey by affine transformation, not only expansion and contraction in the horizontal and vertical directions but also deformation and rotation in an oblique direction can be performed. This means that the aspect ratio can be corrected even when the direction of the loop is oblique to the scanning direction of the frame memory 22 and the graphic monitor 30. However, the minimum required conversion is the address (x, y) of the frame memory 22.
Can be converted to an address (ax, by), b / a
Is the aspect ratio.

The job of the mesh mapping processing unit 26 is generated after converting the data after knit design into data to be actually knitted by a knitting machine (knitting machine data) and simulating the data so as to simulate an actual loop shape. To do. The mesh mapping processing unit 26
This is for virtually trying on the data after the loop simulation on the mannequin, and need not be provided.

FIG. 2 shows the knit paint processing section. In the figure, 32 is a storage area for intarsia data, 34
Is a storage area for organization data, and 36 is a storage area for jacquard data. These are designated and allocated to the frame memory 22, and the data are stored as internal data. The knitted design data is divided into three types, intarsia, organization, and jacquard, and stored for the purpose of facilitating the design, and the data may be stored as one data without being divided. Reference numeral 33 is an organization information addition unit that generates organization data such as a change in the number of stitches from the pattern data, adds it to the contour data of the pattern stored in the intarsia data storage area 32, and stores it in the organization data storage area 34. Let 38,4
Reference numerals 0 and 42 denote monitor data storage areas after the loop size is corrected by the affine transformation means 24, and the areas are allocated and stored in the frame memory 22. Reference numeral 38 is a storage area for the corrected intarsia data, 40 is a storage area for the corrected tissue data, and 42 is a storage area for the corrected jacquard data. These pieces of data are combined by the combining processing unit 28, or are bypassed by the combining processing unit 28 and are displayed as independent data on the graphic monitor 30. The synthesizing unit 28 may not be capable of synthesizing three images at the same time, as long as it is possible to synthesize two images that are highly necessary. The display mode on the monitor 30 is the display mode selection means 44.
To decide.

Reference numeral 46 is a drawing processor, and reference numeral 48 is a coordinate affine transforming means for transforming the external input coordinates of the external input means such as the stylus 16 into the coordinates on the monitor 30. In the embodiment, the position of the external input is input as the internal coordinates corresponding to the internal data, and is converted into the monitor coordinates by the coordinate affine conversion means 48.

Reference numeral 50 is a knitting method input, which uses the keyboard 18 and the external memory 12 to specify, for example, a knitting method (intarsia, jacquard, organization), the number of colored threads, the gauge and the number of stitches. Reference numeral 52 is a loop size determining means, which determines the size of the loop according to the knitting method, gauge, number of stitches, and the like.
Reference numeral 54 is a size input for inputting numerical values from the keyboard 18, input from the stylus 16, pattern data stored in the external memory 12, pattern data read from the scanner 10, and the like. Reference numeral 56 is a pattern data creating means, which creates the pattern data according to the data from the size input 54, and the pattern outer shape determining means 58 determines the outer shape of the pattern. Reference numeral 60 denotes an internal data creating means, which inputs the loop size from the loop size determining means 52 and the outer shape of the template from the template outer shape determining means 58. As a result, one loop generates one pixel of internal data, and the internal data is stored in the data storage areas 32, 34, 36 and the like.

To input a pattern or pattern to the knitted fabric, the stylus 16 or pattern drawing data input 62 (existing pattern or pattern stored in the external memory 12, existing pattern or pattern read from the scanner 10), etc. The input position is specified by the digitizer 14 using the stylus 16, is stored as an internal address, and is displayed as a monitor address. The drawing processor 46 processes the input data and writes it to the pixel specified by the internal address. On the other hand, in the display on the graphic monitor 30, the internal address designated by the digitizer 14 is converted into a monitor address by the coordinate affine converting means 48 and displayed.

The reason why the monitor data after loop size correction is not inversely affine-transformed into internal data is to prevent the accuracy of the internal data from being deteriorated due to the inverse affine transformation. Took priority.

Reference numeral 64 denotes an automatic control processing means for converting internal data into knitting data of a knitting machine. It is known from Japanese Patent Publication No. 3-21661 that the internal data can be converted into knitting machine data (knitting data) when organization data is stored in one pixel as color information and other data is stored as option information. Is. Therefore, if the three types of data of intarsia, organization, and jacquard can be converted into the data format of Japanese Patent Publication No. 3-21661, the internal data can be converted into knitting machine data. Therefore, the organization data is used as it is, and the option line data is generated from the intarsia and jacquard data.
Then, this data is processed by the automatic control processing means of Japanese Patent Publication No. 3-21661 and converted into knitting machine data. 6
A knitting machine data memory 6 and a floppy disk 68 store knitting machine data. Of course, the method of converting into knitting machine data is arbitrary.

FIG. 3 shows the relationship among the pattern data, the internal data, and the monitor data. When the pattern data on the left side of the drawing is created by the internal data creating means 60, the internal data transformed like the center of the drawing is stored in the data storage areas 32, 34 and 36. This is because one loop corresponds to one pixel in the internal data, and the aspect ratio of the loop is not taken into consideration. Next, the internal data is affine-transformed and the aspect ratio of the loop is corrected to be monitor data, which is displayed on the monitor 30 as shown on the right side of the drawing.
When the cursor position of the stylus 16 is indicated by a cross mark, the cursor position is input by the internal address, converted by the coordinate affine conversion means 48, and displayed on the graphic monitor 30 by the monitor address. As a result of these, designers can
I can design.

FIG. 4 shows an algorithm for loop size correction and coordinate affine transformation of the cursor position designated by the stylus 16. First, the display mode selection means 44 selects which data of intarsia, tissue, and jacquard is to be modified, the stylus 16 designates the coordinate position of the cursor by an internal address, the coordinate affine conversion is performed, and the monitor address is displayed. Display on the monitor 30. Next, the drawing area is determined by the stylus 16 or the like, and the data of the drawing process is stored as internal data in, for example, the work memory 23, affine transformed and displayed on the monitor 30. When the designer confirms the drawing, the work memory 2 is stored in the data storage areas 32, 34 and 36 by using the drawing processor 46.
Input the internal data of 3. Work memory 2 in the drawing process
The internal data of 3 is converted into monitor data by the affine conversion means 24, transferred to the data storage areas 38, 40, 42 and displayed on the graphic monitor 30.

FIG. 5 shows the composition of three data, intarsia, organization and jacquard. In the algorithm of Figure 4,
Since the internal data and internal address are virtualized and only the monitor data and monitor address are visible, the monitor data after loop size correction is shown in FIG. 5 and below. In these figures, there are two types of processing, design processing by internal data and internal address, and display system by monitor data and monitor address, and internal data is processed every time the designer confirms the processing on the monitor. And

The original image of the internal data creating means 60 is written in the storage areas 32, 34 and 36 as, for example, three types of data of intarsia, organization and jacquard, and at least the organization data and two types of data of intarsia or jacquard are stored. To do. Then, these data are modified by the stylus 16 or the like, and the modified data is sent to the graphic monitor 30 via the synthesis processing unit 28.
To display. When the correction is completed, the three types of data are converted into one type of data using a reference table or the like, and the automatic control processing means 64 converts the data into knitting data of the knitting machine.

FIG. 6 shows the support of polka dots, repeat patterns, and straight lines by the drawing processor 46. In the figure, 70 is a processor body, 72 is a zoom processing unit, 74 is a movement processing unit, 76 is a copy processing unit, 78 is a polka dot processing unit,
Reference numeral 80 is a repeat processing unit, and 82 is a straight line processing unit. Each of these processing units 72 to 82 performs each job with the help of the processor main body 70. The job of the zoom processing unit 72 is to reduce or enlarge the input pattern or pattern, and the job of the movement processing unit 74 is to move the input pattern or pattern. The job of the copy processing unit 76 is
Data storage areas 32, 34, 36 for patterns and patterns already entered
Is to copy it to other parts of. These processing units 7
2, 74 and 76 are well known in ordinary paint systems and can be easily realized. In Figure 10, polka dot processing, repeat processing,
The algorithm of straight line processing is shown.

FIG. 7 shows the processing in the polka dot processing unit 78.
When designing a polka dot pattern, it is troublesome to draw polka dots with the stylus 16 and copy them one by one with the copy processing unit 76. Then, as shown on the right side of FIG. 7, the circles A, B, C, and D that are the elements of the polka dots are input, and these polka dots A, B, and
Input a reference point E to move or copy C and D at once. The straight line between the reference point E and the individual dots A to D is a line for showing that the dots A to D are related to the reference point E, and is called a control rod. Polka dots A to D and reference point E
Data such as is stored in the work memory 23 as internal data and displayed after being affine-transformed. The cursor position is also designated by the internal address, and coordinate affine-transformed and displayed. If the position where the polka dot pattern is copied on the monitor 30 is designated as the position of the reference point E, the polka dot pattern is copied based on the internal address of the reference point E. The actual copy is polka dot A,
Only B, C and D are used, and the reference point E and control line are not copied.

FIG. 8 shows the processing in the repeat processing section 80. In the figure, C, D, E, and F are points for designating a repeat area, and circles A and B are intersections of the repeat area and the outline of the knitted fabric. Points A, A2, A3 and A4 are points for designating an area occupied by one unit of the pattern. In this case, the width between the points A and A2 is the width of the unit of the pattern. And point A,
In the area designated by A2, A3, A4, input a pattern of 1 unit with the stylus 16 etc., and repeat area (C, D,
The pattern surrounded by (E, F) is picked up, and the repeat processing unit 80 repeatedly copies the unit pattern into the repeat area. As a result, the pattern can be accurately and repeatedly copied by inputting only one unit of the pattern. G is a movement point, and one point in the repeat area is designated by the stylus 16 or the like and clicked. Next, when the stylus 16 is moved to an appropriate position, the pattern is moved to that position or the pattern is copied to that position. In the repeat processing unit 80 as well,
The data in the creation process and the cursor position are processed by the internal data and the internal address, and writing to the data storage areas 32, 34, 36 is also performed in the internal data format. On the other hand, the display on the monitor 30 is affine-transformed and processed by the monitor data and the monitor address.

FIG. 9 shows the operation of the straight line processing section 82. It is difficult in itself to draw a straight line with the stylus 16, and it is even more difficult to specify a regular line with the least aliasing. Therefore, two angle adjustment points are designated for the work memory 23 and the like, and a straight line is interpolated between these points. The data between the angle adjustment points is vector data, and a straight line closest to this vector data, that is, a straight line with the smallest aliasing is generated. The movement of the straight line is the same as the processing of the moving point in the repeat processing unit 80. When one point on the straight line is clicked and moved to a designated point, a new straight line is generated or the straight line is moved to that point. Can be translated. Even in the straight line processing unit 82, the processing in the work memory 23 and the data storage areas 32, 34, 36 is performed by the internal data, and the graphic monitor 30 displays the monitor data subjected to the affine transformation.
