Description

TECHNICAL FIELD [0001] The present invention relates to a method of generating a multi-

The present invention relates to a method for generating a horizontal or vertical polyline for evenly dividing a certain rectangular area, and more particularly to a method for designating a constant rectangular area in a graphics area being processed in a graphic screen processing system and dividing the area equally And more particularly to a method for generating horizontal or vertical multiple lines.

Ordinary users may want to create multiple horizontal lines or vertical lines that evenly divide a certain rectangular area. If you do this manually, it is quite cumbersome because you have to use a ruler and a pencil to calculate the line spacing and scale each line. When the user performs the above operation using a graphic screen processing system such as a word processor or a report generator, a method of copying one line at regular intervals after drawing one line can be used. However, this method is not a satisfactory solution as it alleviates the inconvenience of the user.

In addition, the above-described polyline generation function is often required in a graphic screen processing system composed of a processor, a memory, a graphic display device, other input / output devices, and graphic processing software. For example, when one rectangular object is designated in the graphic screen of the graphics processing system and a certain type of table is to be created, a polyline generation function as described above is required. It is a very difficult and cumbersome task to divide the rectangular object area into equal areas.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to design a rectangular area to be divided by receiving only the number of horizontal or vertical multiplexed lines and coordinate values of two points within a rectangular area to be divided, And a method for generating horizontal or vertical multiple lines for evenly dividing the area.

In order to achieve the above object, the present invention is constructed as follows.

A graphic screen processing system comprising a processor, a memory, a graphic display device, and other input / output devices and graphic processing software, the graphic screen processing system comprising: A method for dividing a rectangular region into a predetermined number of regions is a method including: a first step of receiving a number of horizontal lines and a number of vertical lines to be divided from a user; A second step of receiving coordinate values of two points included in a rectangular area to be evenly divided from a user; A third step of finding a rectangular area to be evenly divided using the coordinate values of the two points; A fourth step of determining whether a horizontal line segmentation or a vertical line segmentation is performed using the coordinate values of the two points; And a fifth step of uniformly dividing the rectangular area to be equalized, which is found in the third step, into a number obtained by adding 1 to the number of input squares in the first step in a manner determined by the fourth step.

The graphic screen processing system in which the present invention operates includes graphic processing software, a memory, a processor, a graphic displayer, and other input / output devices. Wherein the graphics processing software includes all kinds of application software having a graphic screen processing function, the memory being a hardware place in which the graphics processing software is loaded for execution, the processor being hardware for executing the graphics processing software, The graphic display device is a hardware device that displays graphic data processed by the processor as a graphic screen. Other input / output devices may include input devices such as a keyboard and a mouse, and output devices such as a printer and a platter.

In the graphic screen processing system, the graphic processing software generally manages various graphics, symbols, and character strings processed in a graphic screen of the graphic display device in units of an object. Accordingly, the graphic processing software processes information on a rectangle, a straight line, a character string, a picture image, and the like shown in the graphic screen on an object-by-object basis. In the graphic screen processing system, the entire page area refers to the entire graphic area processed by the graphic software, and includes not only the part displayed on the graphic display screen, but also the hidden part in the top, bottom, left and right sides of the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart illustrating a polynomial generation process according to the present invention. First, the number of horizontal lines and the number of vertical lines to be divided must be input from the user (step 100). As a method of receiving the number of the horizontal lines and the number of the vertical lines, a method of creating a dialog box through a graphical user interface (GUI) and receiving the input through the keyboard can be used. At this time, as a more useful method, the value of the number of the horizontal line used immediately before and the value of the number of the vertical line are stored in a predetermined storage medium (for example, a disk) as environment variables, When a new input is received by the keyboard input method, the input values may be used after changing the environment variable, and when the new input is not received, the values may be input from the storage medium.

Next, coordinate values of two points included in the rectangular area to be evenly divided are input from the user (step 110). A method of receiving coordinate values for the two points may be a keyboard input method using a dialog box and a method using a mouse or a light pen.

Next, using the coordinate values of the two points, a rectangular area to be evenly divided is searched (operation 120). Referring to FIG. 2, a process for obtaining a quadrangle to be evenly divided is as follows.

First, when the rectangle area to be evenly divided is R, the size of the entire page area being processed in the graphic screen processing system is set to R (step 200). Then, it is checked whether all the objects on the entire page area being processed in the graphic screen processing system are sequentially searched and whether or not there is a next object to be searched (step 210). If there is no next object to be searched, And the step 120 is completed (step 290). If there is a next object to be searched, it is searched whether the object is a rectangular or round rectangular object (step 220). Here, the rounded rectangle refers to a rectangle formed by rounding the corner portion of the rectangle into an arc.

Then, when the object is a rectangle or a round rectangle, it is searched whether the object includes all of the coordinate values of the two points input in the step 110. In operation 230, The region including the area of R and the area of the new object is set as a new R (step 240), and the step 210 is continued. If all of the coordinate values for two points are not included, step 210 is immediately continued.

If the object is not a rectangle or a round rectangle, it is checked whether the object is a vertical line or a horizontal line. If the object is not a vertical line or a horizontal line, step 210 is performed. Because these objects are excluded from consideration. If it is determined that the next vertical or horizontal object does not divide R and the R is not divided, the process returns to step 210 (step 260). Then, it is determined whether or not there is an area including all the two points inputted in step 110 among the two areas of the divided R (step 270). If there is an area including both of the two points, The region is set as a new R (step 280), and the step 210 is continued. However, if there is no area including all of the coordinate values for the two points, the step 210 is immediately continued.

Referring back to FIG. 1, in the next step, it is determined whether a horizontal line division or a vertical line division is performed using the coordinate values of the two points (operation 130). The step 130 may be implemented by the following method.

That is, when the coordinate values of the two points received in step 110 are (X1, Y1) and (X2, Y2), respectively, ΔX = | X1-X2 | and ΔY = | Y1-Y2 | Next, when ΔX is equal to or larger than ΔY, it is recognized as a horizontal line division, and when ΔX is smaller than ΔY, it is grasped as a vertical line division.

Next, in step 140, the rectangular area to be evenly divided, which is found in step 120, is equally divided by the number obtained by adding the number of rectangles input in step 100 in a manner determined by step 130 (step 140).

Hereinafter, the operation will be described in detail with reference to one embodiment of the present invention.

FIG. 3 illustrates a page area prior to polyline generation to illustrate an embodiment of the present invention. Reference numeral 300 in FIG. 3 denotes the entire page area, and reference numeral 310 denotes a character string object. Reference numerals 330 and 340 denote rectangular objects, reference numerals 320 and 350 denote horizontal line objects, and reference numeral 360 denotes a vertical line object. Next, reference numerals 370 and 380 denote coordinate positions of two points input from the user. In the present embodiment, it is assumed that the graphic software receives 10 as the number of horizontal lines from the user and 5 as the number of the vertical lines, and the objects are managed in accordance with the order of the numbers from 310 to 360.

First, let us consider a process of finding a rectangular area to be evenly divided according to FIG. Initially, R will be allocated the entire page area 300. If the first object 310, which is the next object, is searched, it is not a rectangle or a round rectangular object, nor is it a vertical line or a horizontal line. Next, when the reference number 320 is searched, the horizontal line object or the entire page area, which is the current R value, is not divided. Next, when the reference numeral 330 is searched, the current rectangular area, which is a common object of the entire page area and the current rectangular area, is newly allocated to R since it is a rectangular object and includes two input points 370 and 380. Next, when a reference number 340 object is searched, since the rectangular area is also a rectangular area, a common portion between a rectangle 330 and a rectangle 340 is newly allocated to R. [ Next, when a reference number 350 object is searched, since the two points 370 and 380, which are horizontal line objects and the current R is divided and input, exist in the area below the horizontal line, this area is newly allocated to R. Next, when the reference number 360 object is searched, the current R is divided into the vertical line object and the left vertical line, but the current R is maintained as it is. Since there are no more objects thereafter, the rectangular area to be evenly divided is recognized as a lower part divided by reference numeral 350 horizontal line object among the common parts of reference numbers 340 and 350 rectangle objects.

Next, the step of determining whether the horizontal line segmentation or the vertical line segmentation by the step 130 of FIG. 1 is performed is performed by comparing the distance by the horizontal axis and the vertical axis distance between the point by reference numeral 370 and the point by reference numeral 380. According to this embodiment, the distance by the horizontal axis is longer than the distance by the vertical axis, and is determined as the horizontal line division. This process reduces the burden on the user by allowing the user to grasp the user's intention even when the user does not draw an accurate horizontal line or a vertical line as coordinates of two points when the user uses the mouse. Therefore, 10 horizontal polynomial lines are drawn in the rectangular area determined as described above to be divided into 11 equal areas.

FIG. 4 is a diagram illustrating a page area after generation of a polynomial by the above process.

According to the present invention, in a graphic screen processing system, a rectangular area to be divided is designated by receiving only the number of horizontal or vertical multiplexed lines and coordinate values of two points in a rectangular area to be divided, Since it is possible to generate horizontal or vertical multiple lines, users can write reports in complex form more conveniently and quickly.
