Description

  The present invention relates to a graphic element editing apparatus that displays a graphic element formed based on graphic data on a display device, and more particularly to a graphic element editing apparatus and a graphic element editing apparatus that can scroll and display the entire graphic data. The present invention relates to a scroll method, a graphic element editing program, and a storage medium thereof.

  In so-called CAD that supports the design of industrial products and circuits using a computer, graphic elements of various shapes constituting a design object are displayed on a computer screen (hereinafter simply referred to as a screen). In order to confirm or edit a desired graphic element, the operator repeats the operation of chasing the graphic element with his / her eyes while scrolling or scrolling the screen.

  For smooth scrolling of the screen, there has been proposed a graphic editor that reads a drawing in a display area that exceeds the drawing edge and displays it on the screen together with the original display area when the display range exceeds the drawing edge (for example, Patent Documents). 1). In this way, the portion beyond the drawing edge is joined and displayed in the original display range, thereby enabling smooth screen display without switching the entire screen for each display range. However, since the display method described in Patent Document 1 is equivalent to scrolling the screen, the operator needs the following work.

  FIG. 14A shows an example of a graphic displayed on the screen. For example, when the operator confirms the connection destination of the thick line 101 in FIG. 14A, the connection destination may be displayed in the display range of the screen, but the display range needs to be moved by scrolling the screen. There are many. As a scrolling method, CAD supports a method of operating a mouse and a method of using a scroll bar.

  When operating the mouse, regardless of the position of the pointer, if the mouse is dragged while the middle button in the middle of the left and right click buttons is pressed, the screen scrolls in the dragged direction. If you press and release the middle button and then drag the mouse, you can slowly scroll the screen in the dragged direction. With a mouse with an integrated middle button and wheel, you can scroll the screen in the direction of rotation by rotating the wheel.

FIG. 14E shows an example of a scroll bar. FIG. 14E shows a vertical scroll bar, but the same applies to the horizontal direction. When the scroll bar is used, if the arrow buttons 102 and 104 provided above and below the scroll bar are clicked with the mouse, the screen is instantaneously moved in the direction of the arrow by a predetermined amount. Further, when the scroll box 103 is dragged, the screen can be scrolled in the drag direction. In addition, when the areas 105 and 106 between the scroll box 103 and the arrow buttons 102 and 104 are clicked, the screen can be instantaneously moved by a predetermined amount within a larger range than when the arrow buttons 102 and 104 are clicked. it can.
JP-A-5-151334

  However, in the scroll method using the mouse or the method using the scroll bar, it is possible to scroll vertically or horizontally from anywhere, so the positional relationship between the graphic elements before and after scrolling becomes unclear, and the graphic elements are lost during scrolling. There is a problem of fear. As shown in FIG. 14A, even if the screen is scrolled to confirm the connection destination of the thick line 101, the thick line 101 has a non-linear portion as shown in FIG. 14B or FIG. Since the position in the screen 101 changes, it becomes difficult to follow this with the eyes. Further, when the thickness of the thick line 101 or the surrounding lines gradually changes, there is a high possibility that the graphic element is erroneously discriminated even if these are composed of only straight lines.

  In addition, when scrolling using the arrow buttons 102 and 104 or the areas 105 and 106 of the scroll bar, the screen changes instantaneously, and the position of the thick line 101 in the screen also changes instantaneously. It is never easy to figure out.

  In view of the above problems, the present invention provides a graphic element editing apparatus, a graphic element editing apparatus scroll method, a graphic element editing program, and a storage medium thereof, which can easily determine graphic elements when scrolling a screen. For the purpose.

  In view of the above problems, the present invention provides a graphic element editing apparatus for displaying graphic elements formed based on graphic data on a display device, an overall display means for displaying an overall view of graphic data on a first display unit, Sub-window display means for displaying an overall view on a second display section smaller than one display section, screen dividing means for dividing the second display section into a plurality of cell areas, and the cell area enlarged and displayed on the first display section Screen enlargement means, current display cell clarification means for clearly showing the cell area displayed on the first display section in the cell area of the second display section, and enlarged display on the first display section And an input unit for inputting a cell region switching instruction. When the cell region switching instruction is input by the input unit, the screen enlarging unit expands the predetermined cell region to the first display unit. Display and display current cell explicitly Serves to demonstrate cell area is displayed enlarged on the first display unit, demonstrating a cell area that is enlarged and displayed on the first display unit in the past, and wherein the.

  According to the present invention, since the divided cell areas are scrolled in units, the screen can always be scrolled with a constant scroll amount, and the cell area currently displayed in the sub-window is clearly indicated, so that it is possible to prevent losing sight of graphic elements. . In addition, since the cell area that has already been enlarged and displayed is clear, the oversight of graphic elements is eliminated.

  Further, the present invention provides a graphic element editing apparatus for displaying graphic elements formed based on graphic data on a display device, an overall display means for displaying an overall view of graphic data on a first display unit, and a first display unit Sub-window display means for displaying an overall view on a smaller second display unit, element circumscribed rectangle generating means for generating a circumscribed rectangle of a graphic element selected by the pointing device, and a screen for dividing the circumscribed rectangle into a plurality of cell areas Splitting means, screen enlarging means for enlarging and displaying the cell area on the first display section, and current display for clearly displaying the cell area enlarged and displayed on the first display section in the cell area of the second display section A cell clarification unit and an input unit for inputting a cell region switching instruction displayed in an enlarged manner on the first display unit, and when the cell region switching instruction is input by the input unit, The area enlarging means enlarges and displays the predetermined cell area on the first display section, and the currently displayed cell specifying means clearly indicates the cell area enlarged and displayed on the first display section. The cell area enlarged and displayed on the first display unit is clearly indicated.

  According to the present invention, since the divided cell areas are scrolled in units, the screen can always be scrolled with a constant scroll amount, and the cell area currently displayed in the sub-window is clearly indicated, so that it is possible to prevent losing sight of graphic elements. . In addition, since the cell area that has already been enlarged and displayed is clear, the oversight of graphic elements is eliminated. Further, since the circumscribed rectangle of the selected graphic element is divided into cell areas, unnecessary scrolling can be reduced.

  In one embodiment of the present invention, the screen enlarging means has an overlap display means for enlarging and displaying an expanded cell area including a cell area, which is wider than the cell area by a predesignated area. The present display cell specifying means specifies the extended cell area on the second display unit.

  According to the present invention, since the overlap amount can be specified, the screen can be scrolled in units of cell areas while overlapping according to the operator's preference and the characteristics of the graphic elements. Too much can be prevented.

  In one embodiment of the present invention, the screen enlarging means enlarges and displays only the cell region in which the graphic element selected by the pointing device exists on the first display unit.

  According to the present invention, it is possible to enlarge and display only the cell region in which the graphic element to be confirmed exists, and thus it is possible to scroll efficiently.

  When scrolling the screen, it is possible to provide a graphic element editing apparatus, a graphic element editing apparatus scroll method, a graphic element editing program, and a storage medium thereof that can easily determine graphic elements.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

  FIG. 1A shows an example of a perspective view of the graphic element editing apparatus 10. The graphic element editing apparatus 10 is composed of a computer system and has a computer main body 11, a display 12, a keyboard 13, and a mouse 14. The computer main body 11 operates based on a graphic element editing program installed in advance. The graphic element editing program displays the graphic data of the product on the display 12, and displays graphic elements such as lines and circles while scrolling the screen by inputting a user operation.

  FIG. 1B shows an example of a hardware configuration diagram of the graphic element editing apparatus 10. The computer main body 11 is configured to include a CPU 21, a RAM 22, a storage device 23 such as an HDD or a flash memory, a display control unit 24, a drive device 25, a communication device 26, and an input device 27, which are mutually connected by a bus. The

  The CPU 21 provides various functions by reading and executing a program such as an OS or an application from the storage device 23 and comprehensively controls processing performed by the computer main body 11. The RAM 22 is a work area for temporarily storing the OS, programs, and data. The storage device 23 stores an OS, a graphic element editing program, and the like. The display control unit 24 draws on the display 12 such as a liquid crystal with a predetermined resolution and the number of colors based on the screen information instructed by the program. For example, a GUI (Graphical User Interface) screen is formed, and various windows and menu buttons necessary for operating the graphic element editing apparatus 10 are displayed on the display 12. The drive device 25 is configured such that the storage medium 28 can be inserted, and reads the data stored in the storage medium 28 and sends it to the storage device 23 or the like. A graphic element editing program is stored in the storage medium 28, and the graphic element editing program loaded by the drive device 25 is installed in the storage device 23. The communication device 26 is an interface for connecting to a network such as the Internet or a LAN, and includes, for example, a modem, a NIC (Network Interface Card), or the like. The input device 27 is a device for inputting various operation instructions from the user, such as the keyboard 13 and the mouse 14.

  FIG. 2 shows a functional block diagram of the graphic element editing apparatus 10 realized by the CPU 21 executing the graphic editing program.

  The entire display means 31 displays the entire predetermined graphic data 38 (hereinafter referred to as an overall view) on the entire surface of the display 12 or a predetermined maximum display area. The overall diagram of the graphic data 38 is the entire graphic data 38 that is handled integrally, such as one circuit diagram of a chip mounting board, one IC package, and one printed circuit board. Only a predetermined range of the predetermined graphic data 38 may be displayed.

  FIG. 3 shows an example of the maximum display area 41 displayed on the GUI formed by the graphic editing program. The overall display means 31 displays the overall view of the graphic data 38 read from the storage device 23 so that it fits in the maximum display area 41 regardless of the size of the overall view.

  The screen dividing means 32 divides the entire view displayed in the maximum display area 41 and the sub window 42. The vertical direction and the horizontal direction of the maximum display area 41 are each divided into a predetermined number. In FIG. 3, the dividing lines of the maximum display area 41 and the sub window 42 are indicated by dotted lines. Hereinafter, the rectangular area divided by the division is referred to as a cell area.

  When the operator clicks the division button 43a of the toolbar 43 formed by the graphic editing program, the screen division unit 32 divides the maximum display area 41 and the subwindow 42 into predetermined m × n (4 × 4 in the figure) areas. The number of divisions m × n can be input by an operator. For example, after the division button 43a is clicked, when the operator clicks the division number button 43b, input fields for the division numbers m and n are displayed, and the maximum display area 41 is automatically subdivided when a desired number is input. .

  The screen enlarging means 35 enlarges and displays one of the divided maximum display areas 41 in the maximum display area 41. If the graphic data 38 is vector data, the graphic elements in the cell area can be enlarged and displayed as they are in the maximum display area 41. If the graphic data 38 is bitmap data, it is enlarged and displayed by performing jaggy processing such as smoothing and anti-aliasing.

  The cell area to be enlarged may be selected by clicking the desired cell area with the mouse 14 by the operator. For example, the screen enlargement means 35 automatically extracts the upper left cell area or the last enlarged cell area. And may be enlarged.

  The sub window display means 33 displays the overall view on the sub window 42. Accordingly, the predetermined cell area is enlarged and displayed in the maximum display area 41, and the whole view is reduced and displayed in the sub window 42. As described above, the sub window 42 is also divided into the same division number m × n as the maximum display area 41.

  The current display cell specifying means 34 specifies in the sub-window 42 where the currently enlarged cell area corresponds to the whole view. For example, when the cell area S is displayed in the maximum display area 41, the currently displayed cell specifying means 34 highlights the cell area S, changes the color of the dividing line, blinks the dividing line, etc. Clarify the enlarged cell area.

  Further, the screen enlarging means 35 has an overlap display means 36, and when the cell area is enlarged and displayed, the cell area can be enlarged and displayed with a predetermined margin. This margin is called the overlap amount. For example, when the overlap display means 36 is operating (when the function is on), the screen enlargement means 35 displays other cell areas by the overlap amount (for example, 5 to 10%) indicated by the overlap display means 36. Including the enlarged display in the maximum display area 41. When the cell region S is enlarged and displayed in the figure, the hatched region is the overlap amount, and is enlarged and displayed including the overlap amount.

  The overlap amount can be input when the operator clicks the overlap amount designation button 43 d on the toolbar 43. The overlap display means 36 instructs the input value to the screen enlargement means 35. Since the overlap amount can be specified, the screen can be scrolled in units of cell area while overlapping according to the operator's preference and the characteristics of the graphic elements, and the scroll amount may not be enough to scroll again or scroll too much Can be prevented.

  Therefore, when the cell area is switched and scrolled, the display range always overlaps by a certain amount, so that the operator can easily confirm the graphic element.

  The operator can scroll the enlarged view while grasping the relationship between the cell region displayed in the maximum display region 41 and the overall view in this way. For example, when a desired cell area is clicked with the mouse 14 in the sub window 42, the clicked cell area is enlarged and displayed in the maximum display area 41, and when the cursor key is pressed, the cell area adjacent to the pressed arrow is enlarged in the maximum display area 41. Is displayed.

  The scroll direction designating unit 37 designates the scroll direction of the cell area that is enlarged and displayed in the maximum display area 41. For example, if the cursor key is pressed, the scroll direction specifying unit 37 specifies the scroll direction according to the pressed cursor key, or specifies the scroll direction based on a scroll method registered in advance. The operator can select from a plurality of registered scroll methods.

  FIG. 4 shows an example of the scroll method. The selectable scroll methods are, for example, “right direction”, “left direction”, “horizontal direction”, “zigzag”, “order of cell areas with many designated graphic elements”, and the like. As shown in FIG. 4A, in the “right direction”, when adjacent right cell areas are selected in order and reach the right end, the cell areas are similarly scrolled from the left end cell area one row below. As shown in FIG. 4B, in the “left direction”, when adjacent left cell areas are sequentially selected and reach the right end, the cell areas are similarly scrolled from the right end cell area one row below. As shown in FIG. 4C, in the “horizontal direction”, when the cell area adjacent to the right or left direction is scrolled to reach the right or left edge, the cell moves to the lower line and moves to the upper line. Scrolls adjacent cell areas in the opposite direction. As shown in FIG. 4D, in the “zigzag”, when the cell area adjacent to the lower or upper direction is scrolled to reach the upper or lower edge, the cell moves to the right column and moves to the left column. Scrolls adjacent cell areas in the opposite direction. As shown in FIG. 4E, in the “order of cell areas with many designated graphic elements”, for example, from a cell area in which many graphic elements (Δ in the figure) selected by the mouse 14 or the like are drawn. Scroll in order.

  Such a scrolling method can be selected by clicking the scrolling method button 43c on the toolbar 43. Further, the timing for switching the cell area may be when a predetermined key is pressed, or may be switched automatically every predetermined time.

  Since the cell area that has already been enlarged and displayed is known to the screen enlargement means 35 and the sub window display means 33, the sub window display means 33 clearly indicates the cell area immediately before the movement in the sub window 42. In the figure, the cell area immediately before the movement is indicated by a mark 44. In addition, the color of the dividing line may be changed, or the dividing line may be blinked, for example, by a technique that can be distinguished from the enlarged cell region. Further, the mark 44 may be displayed not only in the cell area immediately before the movement, but also in all cell areas that have been enlarged and displayed in the past. In this case, the display order may be clarified by adding a sequential number to the mark 44. preferable.

Based on the above configuration, the procedure by which the graphic element editing apparatus 10 scrolls the entire diagram will be described with reference to the flowchart of FIG.
(S10)
The graphic element editing apparatus 10 reads the graphic data 38 from the storage device 23 by the operation of the operator. As shown in FIG. 3, the operator clicks “file” from the menu of the GUI formed by the graphic editing program, and selects desired graphic data 38.
(S20)
The whole display means 31 displays the whole figure of the read graphic data 38 in the maximum display area 41. After reading the graphic data 38, it may be automatically displayed in the maximum display area 41, or may be displayed when a predetermined command is executed.

FIG. 6A shows an example of the maximum display area 41 and the sub window 42 displaying the whole view. At this time, the entire display is displayed on the maximum display area 41 and the sub window 42 at different scales.
(S30)
Next, when the division button 43a is clicked by the operator, the screen division means 32 divides the entire view. The division number m × n is designated in advance, for example.

  FIG. 6B shows an example of the maximum display area 41 and the subwindow 42 divided into 4 × 4. At this point, each of the maximum display area 41 and the sub window 42 is similarly divided.

  It can be divided into multiple stages. FIG. 7 shows a maximum display area 41 and a sub window 42 divided into two stages. In this case, the sub-window 42 displays an overall view 42a and a cell area diagram 42b that enlarges and displays one cell area of the overall view 42a, and the maximum display area 41 includes cells obtained by further dividing the cell area diagram 42b. The area is enlarged. Therefore, the cell area diagram 42b is enlarged 4 × 4 times and the maximum display area 41 is enlarged 16 × 16 with respect to the original overall view. In addition, as will be described in step S50, both the overall view 42a and the cell region view 42b clearly show the cell region currently being enlarged.

  Further, the magnification of the cell area to be enlarged and displayed in the maximum display area 41 may be automatically determined. In this case, the magnification is determined in advance, for example, by determining an area of a predetermined size of the original graphic data (for example, by determining the wiring width to be a predetermined length, or by extracting a 5 [mm] × 5 [mm] corner) Is determined to be one cell region.

(S40, S50)
Next, when a cell area to be enlarged and displayed first is selected by the operator, the screen enlargement means 35 enlarges and displays the selected cell area. In parallel, the sub-window display means 33 clearly shows the cell area being enlarged.

  FIG. 8A shows an example of the maximum display area 41 and the sub window 42 for enlarging and displaying the cell area of the second row in the leftmost column. In the maximum display area 41, the graphic elements of the cell area are enlarged and displayed, and in the subwindow 42, the cell area of the second row in the leftmost column is clearly shown. FIG. 8A shows the subwindow 42 when there is no overlap and when there is overlap.

(S60, S70, S80)
Then, the graphic element editing apparatus 10 determines whether or not a scroll operation is input from the operator via the input device 27. When the scroll operation is input, the graphic element editing apparatus 10 enlarges and displays the next cell area. The next cell area is selected by a cursor key or determined based on a scroll method registered in advance.

  FIG. 8B shows an example of the maximum display area 41 and the subwindow 42 when scrolling to the cell area of the third row in the leftmost column. In the maximum display area 41, the graphic elements of the cell area are enlarged and displayed, and the cell area of the third row in the leftmost column is clearly shown in the subwindow 42. A mark 44 is displayed in the cell area immediately before the movement (the cell area in the second row in the leftmost column).

  As described above, the graphic element editing apparatus 10 according to the present embodiment can prevent the graphic element from being lost or mistakenly determined because the display range accurately moves in the vertical direction or the horizontal direction. Since the cell area to be enlarged can be scrolled while overlapping, the graphic element can be easily followed. In addition, since the mark is displayed in the cell area immediately before the movement that has already been confirmed, all the cell areas can be confirmed without oversight.

  In the first embodiment, the whole figure is divided, but in this method, there is a cell area that does not include a desired graphic element, and scrolling to that cell area is performed. Since scrolling a cell area where a desired graphic element does not exist reduces the work efficiency, this embodiment will describe the graphic element editing apparatus 10 capable of dividing only an area where a predetermined graphic element exists.

  FIG. 9 shows a functional block diagram of the graphic element editing apparatus 10 realized by the CPU 21 executing the graphic editing program. In FIG. 9, the same components as those in FIG.

  The functional block diagram of FIG. 9 has element circumscribed rectangle generating means 39. The element circumscribed rectangle generating unit 39 generates a circumscribed rectangle for the selected graphic element. For example, when the element selection button 43 e of the toolbar 43 is clicked with the mouse 14, the element circumscribed rectangle generating unit 39 detects a graphic element that the operator selects with the mouse 14 from the maximum display area 41. Then, the element circumscribed rectangle generating means 39 traces the selected graphic element and detects the left and right end coordinates in the horizontal direction, the upper and lower end coordinates in the vertical direction (hereinafter, the four coordinates are referred to as the outermost coordinates). Then, a rectangular area including the outermost coordinates is generated. Further, when not only the selected graphic element but also a graphic element similar to the selected graphic element exists in the overall view, those circumscribed rectangles can be generated by changing the color.

  When the division button 43a is clicked, the screen dividing unit 32 divides the circumscribed rectangle into a predetermined m × n area. Therefore, one cell area may be narrower than dividing the maximum display area 41, but if the size of one cell area is less than or equal to a predetermined size, the screen dividing means 32 reduces the division numbers m and n. Adjust the cell area size. Also in this embodiment, the number of divisions can be specified by operating the number of divisions button 43b.

  In this embodiment, the scroll direction designating unit 37 can prohibit scrolling to a cell area where the selected graphic element does not exist. Therefore, when the registered scroll method shown in FIG. 4 is selected, only the cell region where the selected graphic element exists is automatically scrolled. Further, even if the operator attempts to move to the cell area where the selected graphic element does not exist with the cursor key or the like, the operator cannot scroll.

A procedure in which the graphic element editing apparatus 10 scrolls the circumscribed rectangle in the overall view will be described with reference to the flowchart of FIG.
(S10)
The graphic element editing apparatus 10 reads the graphic data 38 from the storage device 23 by the operation of the operator. As shown in FIG. 3, the operator clicks “file” from the menu of the GUI formed by the graphic editing program, and selects desired graphic data 38.
(S20)
The whole display means 31 displays the whole figure of the read graphic data 38 in the maximum display area 41. After reading the graphic data 38, it may be automatically displayed in the maximum display area 41, or may be displayed when a predetermined command is executed.

FIG. 11A shows an example of the maximum display area 41 and the sub window 42 displaying the entire view. At this time, the entire display is displayed on the maximum display area 41 and the sub window 42 at different scales.
(S21)
Next, when the element selection button 43e is clicked by the operator and a predetermined graphic element is selected, the element circumscribed rectangle generating means 39 detects the selected graphic element and generates a circumscribed rectangle from the outermost coordinates. In FIG. 11A, for example, when a graphic element 45 is selected, the element circumscribed rectangle generating means 39 generates a circumscribed rectangle 46 shown in FIG. When the circumscribed rectangle 46 is generated in the maximum display area 41, the sub window display means 33 generates the same circumscribed rectangle 46 in the sub window 42.
(S31)
Next, when the division button 43 a is clicked by the operator, the screen dividing means 32 divides the circumscribed rectangle 46. The division number m × n is designated in advance, for example.

  FIG. 12A shows an example of the maximum display area 41 and the subwindow 42 divided into 4 × 4. At this point, each of the maximum display area 41 and the sub window 42 is similarly divided.

  Further, the sub-window display means 33 clearly indicates to the operator, for example, by highlighting only the cell area where the selected graphic element exists or by changing the color. With such a display, the operator can easily grasp the cell area to be scrolled.

(S40, S50)
Next, when a cell area to be enlarged and displayed first is selected by the operator, the screen enlargement means 35 enlarges and displays the selected cell area. In parallel, the sub-window display means 33 clearly shows the cell area being enlarged.

  FIG. 12B shows an example of the maximum display area 41 and the sub window 42 that enlarge and display the cell area of the fourth row in the leftmost column. In the maximum display area 41, the graphic elements of the cell area are enlarged and displayed, and the cell area of the fourth row in the leftmost column is clearly shown in the subwindow 42. FIG. 12B shows the subwindows 42 when there is no overlap and when there is overlap.

(S60, S71, S80)
Then, the graphic element editing apparatus 10 determines whether or not there is a scroll operation from the operator, and when the scroll operation is input, enlarges and displays the next cell area. The next cell area is selected by a cursor key or determined from a scroll method registered in advance.

  In this embodiment, it is prohibited to scroll to a cell area where the graphic element selected in step S21 does not exist. For example, if the cell area of the fourth row in the leftmost column is currently enlarged and displayed in the maximum display area 41, the operator may attempt to enlarge and display the cell region above it (the third row in the leftmost column) using the cursor key. The explicit frame of the sub window 42 does not move. Further, when the scroll destination is automatically determined, scrolling is not performed to the cell area where the graphic element selected in step S21 does not exist. Since only the cell region where the graphic element to be confirmed exists can be moved, the circumscribed rectangle 46 can be scrolled efficiently.

  FIG. 13 shows an example of the maximum display area 41 and the sub window 42 when scrolling to the cell area of the fourth row in the second column from the left. In the maximum display area 41, the graphic elements of the cell area are displayed in an enlarged manner, and the cell area in the fourth row in the second column from the left is clearly shown in the subwindow 42. A mark 44 is displayed in the cell area immediately before the movement (the cell area in the fourth row of the leftmost column).

  In addition to the effects of the first embodiment, the graphic element editing apparatus 10 according to the present embodiment can move only the cell region where the graphic element to be confirmed exists, and therefore can efficiently scroll the circumscribed rectangle 46.
