[0031]
In addition to the main panel 61, various panels 71 may be displayed and operated on the panel 71 as necessary.
[0032]
Hereinafter, a method that can be input by the operator in the present embodiment via the software panel displayed on the display device 41 will be described with reference to FIG.
[0033]
When inputting from the keyboard 11, the operator inputs the character or numerical value after indicating the character input area 64 with the mouse 12 or the keyboard 11. Further, when inputting with the mouse 12, the following method is used.
[0034]
First, there are the following two methods (1) and (2) for selecting a specific element or button.
[0035]
(1) Element selection: The operator moves the mouse pointer 63 to a desired position of the drawing pattern (pattern displayed by the CPU 21 based on the print data) displayed in the drawing area 62, and at that position, For example, an element to be operated is selected by pressing the left mouse button.
[0036]
(2) Button selection: The operator places a mouse at predetermined positions of various buttons 65, general-purpose buttons 66, and various buttons 72 displayed in the panel 71 displayed as necessary, which are displayed on the main panel 61. By moving the pointer 63 and pressing the left mouse button at that position, for example, a button to be operated is selected.
[0037]
In addition, there are five methods (3) to (7) below for specifying a specific position on the drawing area 62.
[0038]
(3) Arbitrary designation: The position is designated by moving the mouse pointer 63 to an arbitrary position on the drawing area 62 and pressing the right mouse button at that position, for example.
[0039]
(4) Point designation: A position is designated by selecting an element of a point displayed in the drawing area 62.
[0040]

[0041]
Here, when there are a plurality of feature points, a method for specifying one point includes a method in which the CPU 21 automatically extracts a feature point closest to the position of the mouse pointer 63 when an element is selected, and a plurality of feature points. There is a method of specifying one point from among the points.
[0042]
FIG. 5 shows an example of feature points of each element of graphic data. In the figure, the points indicated by * are characteristic points that characterize the shapes of various figures. That is, in FIG. 5, the specific positions of feature points characterizing various graphic data are as shown below.

[0044]
Here, when a single line element has its own intersection, that is, when it is self-intersecting, it is only necessary to select one line element. In other cases, two line elements are designated (see FIG. 6).
[0045]
When there are a plurality of intersections, a method for specifying one point includes a method in which the CPU 21 automatically extracts an intersection closest to the position of the mouse pointer 63 when an element is selected earlier or later, There is a method of specifying one point from the above.
[0046]
(7) Point designation on line: By selecting one line element such as a line segment or a circle displayed in the drawing area 62, a point on the line element closest to the position of the mouse pointer 63 at that time is selected. The CPU 21 calculates and designates the position.
[0047]
FIG. 7 shows an example in which an arc is selected as an element and a position is designated by line designation. FIG. 7 shows that the element selection is performed in the order of the line segment and the arc at the position indicated by the mark, and the position of the mark * is designated by the intersection point designation. The points marked with レ are points near the arc, and the points marked with * are points on the arc.

[0101]
Each print attribute data in the print data can be specified by a data number uniquely assigned in the print data. Although the necessary data is different for each print attribute, the CPU 21 can identify these by the data type code.
[0102]
The attribute setting flag is a flag that specifies whether or not the printing attribute data is valid. In the element data indicating the print attribute data for which the attribute setting flag is valid, the element is displayed according to the corresponding print attribute data.
[0103]
On the other hand, in the element data indicating the print attribute data for which the attribute setting flag is invalid, it is assumed that the corresponding print attribute is not set, and the default data stored in advance in the ROM 31 or the external storage device 33 is assumed. Elements are displayed according to print attributes.
[0104]
In addition, when each element data has a data structure that can have a hierarchical relationship, it is possible to perform control according to the printing attributes of the upper (or lower) elements.

[0107]
FIG. 8 shows an example of a print data file created by the drawing instruction apparatus according to the present embodiment based on the data structure of the print data described above.
[0108]
The print data shown in FIG. 8 is print data for printing a figure having a shape as shown in FIG. 9, and the figure represented by the print data shown in FIG. 9 is an element of a plurality of types of basic figures. It consists of one line segment row, two circles, and two points of the lower left point and upper right point of the circumscribed rectangle of these three elements (the two points are not displayed and cannot be selected). These one line section row and two circles have the same display attribute (display), selection attribute (selectable), line attribute (solid line, line width 20 mm), and different color attributes. It shall be.
[0109]
<Data structure of group figure>
Next, among the data structures of the print data described above, the data structures of symbols and illustrations, which are group graphics, will be described in detail.
[0110]
First, the data structure of the symbol will be described.
[0111]
In the present embodiment, a symbol is a figure that is repeatedly used, such as a symbol defined by a standard or a logo mark, and is a graphic data element (line segment, circle, etc.) or character data element (text). Is an element created by combining
[0112]
When the content of the symbol data file is updated due to a change in the standard, etc., in this embodiment, all the corresponding symbols already laid out as part of the print data are updated to maintain data synchronization. can do. That is, the drawing instruction apparatus according to the present embodiment holds symbol data in the following data structure.
[0113]
In the print data, only the folder name and file name for specifying the location of the symbol data file and information necessary for laying out the symbols are stored.
[0114]
Also, a symbol data file is created separately from the print data file in which the print data is saved in the file. The symbol data file has the following file structure.
Layout base rectangle lower left point coordinates: p1 [2],
-Layout reference rectangle upper right point coordinates: p2 [2],
・ Component data: Arbitrary element data (plural)
Print attribute data: Necessary print attribute data (plural).
[0115]
Although the layout reference rectangle will be described later, if the layout reference rectangle is determined, it is possible to specify information on the position and size necessary for laying out symbols as print data. For example, as the layout reference rectangle, it is possible to designate a minimum rectangle (referred to as a circumscribed rectangle) surrounding the visible portion of the symbol.
[0116]
If the circumscribing rectangle data of the corresponding symbol is registered as the layout reference rectangle when creating the symbol data file, there is no need to recalculate the circumscribing rectangle of the symbol when the symbol data file is read again.
[0117]
Each component data of the symbol is expressed by a relative coordinate value with respect to the lower left point of the layout reference rectangle.
[0118]
For each print attribute data, as in the case of print data, the print attribute data necessary for displaying each component data is stored separately from the element data.
[0119]
As described above, in the present embodiment, even if the print data file including the changed symbol is not intentionally updated, the print data file in the print data can be simply read from the external storage device 33 into the RAM 32. The symbol data is automatically updated to the contents of the latest symbol data file, and the data can be automatically synchronized.
[0120]
Next, the data structure of an illustration which is another group figure will be described.
[0121]
In this embodiment, an illustration is a figure that is repeatedly used, such as a template figure. This is also a combination of graphic data elements (line segments, circles, etc.) and character data elements (text) like symbols. Are created.
[0122]
Unlike the case of the symbol described above, the illustration is used when it is desired to make changes freely without being synchronized with the contents of the original illustration data file after it has been laid out as part of the print data. .
[0123]
Therefore, in the case of illustration data, unlike the automatic update of symbol data described above, even if the contents of the illustration data file are updated, the corresponding illustration already laid out as part of the print data is updated. There is no synchronization.
[0124]
Therefore, in the drawing instruction apparatus according to the present embodiment, illustration data is held in the following data structure.
[0125]
In other words, in the print data, in addition to the folder name and file name for specifying the location of the illustration data file, and the information necessary to lay out the illustration, the illustration read from the illustration data file is actually configured. Each element data to be held is held.
[0126]
Also, an illustration data file is created separately from the print data file. The illustration data file has the following file structure.
Layout base rectangle lower left point coordinates: p1 [2],
-Layout reference rectangle upper right point coordinates: p2 [2],
・ Component data: Arbitrary element data (plural)
Print attribute data: Necessary print attribute data (plural).
[0127]
This structure is the same as the file structure of the symbol data file. When reading this into the print data, the specified layout reference point coordinates are used as the origin, and each component data in the illustration data file is expanded (coordinate converted) according to the specified layout angle and layout scale. The illustration element data is different from the symbol in that it is all retained.
[0128]
[Pick processing]
Next, pick processing executed by the drawing instruction apparatus shown in FIG. 2 in order to realize the above-described drawing control will be described.
[0129]
FIG. 1 is a flowchart showing a pick processing procedure in the first embodiment, which is executed by the CPU 21.
[0130]
In the figure, in the environment of step S1: WYSIWIG, the input coordinate pointed out by the operator using the mouse 12 or the like while looking at the display device 41 is taken out (see FIG. 14), and the coordinate value is read and written to the storage device 32. Alternatively, it is stored in an external storage device 33 (hereinafter collectively referred to as a storage device).
[0131]
Step S2: Based on the coordinate value stored in Step S1 and the display position data of the element graphic displayed on the display device 41, the element graphic that may be selected by the operator is determined, and the possibility of selection may be determined. An identification number or the like indicating a certain element graphic is stored in the storage device as a selectable element list and is taken out in order (see FIG. 14).
[0132]
Step S3: In accordance with the identification numbers of the graphic elements taken out in order in step S2, the contour graphic is calculated based on the geometry and attribute data of each graphic element stored in advance and stored in the storage device (see FIG. 15). ).
[0133]
Step S4: It is determined whether or not there is a hit based on the input coordinates saved in Step S1 and the contour graphic information saved in Step S3.
[0134]
Here, details of the processing in step S4 will be described with reference to FIG.
[0135]
In FIG. 19, step S4-1: A pick window (region having a predetermined area) is created based on the input coordinates (see FIG. 16). The pick window creation procedure may be performed according to the flowchart shown in FIG.
[0136]
In FIG. 20, step S4-1-1: The side length input by the storage device or the operator is acquired as the side length L of the pick window.
[0137]
Step S4-1-2: The display device 41 has a predetermined length. The side length L is converted to L ′. Specifically, when the display coordinate system is enlarged and displayed on the display device 41, a predetermined length L reflecting the side length L on the display device by processing such as dividing the side length L by the scale value. Convert to '.
[0138]
Step S4-1-3: A square having a side length L ′ calculated in Step S4-1-2 with the input coordinates as the center is set as a pick window.
[0139]
Next, returning to the description of FIG. 19, step S4-2: It is determined whether the pick window obtained as described above interferes with the contour figure obtained in step S3 (see FIG. 17).
[0140]
Steps S4-3 to S4-5: In step S4-2, if there is interference, it is determined that there is a hit. If there is no interference, it is determined that there is no hit.
[0141]
The specific procedure in step S4-2 may be performed according to the flowchart shown in FIG.
[0142]
In FIG. 21, step SS 4-2-1: a circumscribed rectangle of the contour figure of the display image taking out the attribute of each element and the like is extracted.
[0143]
Step S4-2-2: It is checked whether the pick window interferes with the circumscribed rectangle of the contour figure obtained as described above. Since the purpose of this step is to check whether the interference is rough with a small amount of calculation, it may be obtained geometrically in consideration of the printing attributes.
[0144]
Steps S4-2-3 to S4-2-6: If it is determined that there is no possibility of interference, it is determined that there is no hit in Step S4-2-6, and if it is determined that there is a possibility of interference, Step S4 In 2-2-4, it is checked whether the pick window and the circumscribed rectangle of the contour graphic actually interfere with each other using the contour graphic data. In step S4-2-5, the hit is identified according to the result. To do. Here, a more specific procedure will be described later with reference to FIG.
[0145]
In FIG. 22, step S4-2-3-1: A bitmap image of the display image when the contour graphic is displayed on the display device 41 is calculated.
[0146]
Step S4-2-3-2: A bitmap image of the display image when the pick window is displayed on the display device 41 is calculated.
[0147]
Step S4-2-3-3: It is checked whether each pixel is interfering in the bitmap image of the contour graphic and the pick window obtained as described above. This can be done by taking the logical product of each pixel.
[0148]
Steps S4-2-3-4 to S4-2-3-6: If even one pixel interferes, it is determined that there is a hit, and if no pixel interferes, it is determined that there is no hit.
[0149]
Here, the description returns to FIG. Steps S5 to S6: The elements determined to be hit in step S4 described above are stored in the storage device as selected element candidates.
[0150]
Step S7: It is determined whether or not there are still registered selection elements. If there are, the process returns to Step S3 and the above-described processing from Step S3 to Step S6 is performed for the remaining selected elements. .
[0151]
Steps S8 to S10: It is determined whether there is a selection element candidate (step S8). If there is a selection element, the selection element is determined based on a certain criterion among the hit elements (step S9). (Step S10).
[0152]
Here, details of the processing in step S9 will be described with reference to FIG.
[0153]
In FIG. 23, Step S9-1: Search for the highest priority element among the hit elements. It is assumed that priorities are set in advance for each element.
[0154]
As a result of the search, if there are a plurality of elements having the highest priority, the following processing (S8-2) and the following processing is performed.
[0155]
Step S9-2, Step S9-6: As a result of the search, it is determined whether there are a plurality of elements having the highest priority (step S9-2). If there is only one element, the element is determined in step S9-6. As a selection element.
[0156]
Step S9-3: As a result of the determination in step S9-2, there are a plurality of elements having the highest priority. Therefore, the plurality of elements having the highest priority obtained as described above are classified for each element type, The one having the highest priority according to the priority set for each type is searched.
[0157]
In addition, as the priority for each element type, the highest priority is given to the dots, the lowest priority is given to the filled figure, and the other priority is the others. The reason for this is that the point is generally hidden behind other elements and difficult to select, so the filled figure hides other elements and is easy to select. This makes it easier to select various types of elements equally. (See Figure 13)
A more specific procedure of step S9-3 may be performed as shown in the flowchart of FIG.
[0158]
In FIG. 24, Step S9-3-1 to Step S9-3-2: Search for an element type of point, and if there is a point, take it out. If there is no point, the process proceeds to step S9-3-4 and subsequent steps.
[0159]
Step S9-3-4 to Step S9-3-7: If the element type is not a filled figure, and if there is a non-filled figure, the figure is taken out in step S9-3-3. On the other hand, if there is no non-filled figure, the filled figure is taken out in step S9-3-7.
[0160]
Step S9-4: As a result of searching in step S9-3, it is determined whether there are a plurality of elements. If there are a plurality of elements, the process proceeds to step S9-5. If there is only one element, the process proceeds to step S9-6. The element is selected.
[0161]
Step S9-5: The selected figure is determined according to the order of the drawing list. Here, the drawing priority of each element is managed by a list. In this list, for example, the first one is drawn first, and the first one is written later. As a result, the one behind the list is displayed as displayed on the near side for the operator of the display device 41. At this time, if there are a plurality of selected candidate elements, the element on the foremost side will be selected if the last one in the drawing list is selected.
[0162]
According to the first embodiment as described above, pick processing with excellent operability and considering print attributes is realized.
[0163]
[Second Embodiment]
Next, a second embodiment based on the drawing instruction apparatus according to the first embodiment described above will be described. In the following description, the description similar to that of the first embodiment will be omitted, and the description will focus on the characteristic part of the present embodiment.
[0164]
The drawing instruction apparatus according to the present embodiment is different from the first embodiment in which the process in step S4-2-3 is performed according to the flowchart shown in FIG. 25 according to the flowchart shown in FIG.
[0165]
In FIG. 25, step S4-2-3-1A to step S4-2-3-3A: Check whether the element data and the pick window geometrically interfere with each other, and check whether the element data and the pick window interfere geometrically. Is calculated and obtained (step S4-2-3-1A). As a result, if it is determined that there is interference, it is determined that a hit has been made (step S4-2-3-3A). If it is determined that there is no interference, it is determined that there is no hit (step S4-2-3-3). 4A).
[0166]
Also according to this embodiment, substantially the same effect as that of the first embodiment can be obtained.
[0167]
[Third Embodiment]
Next, a third embodiment based on the drawing instruction apparatus according to the first embodiment described above will be described. In the following description, the description similar to that of the first embodiment will be omitted, and the description will focus on the characteristic part of the present embodiment.
[0168]
The drawing instruction apparatus according to the present embodiment is different from the first embodiment in which the process in step S4-2-3 is performed according to the flowchart shown in FIG. 26 according to the flowchart shown in FIG.
[0169]
In FIG. 26, step S4-2-3-1B: The sum of the rectangles of the font boxes of each character constituting the character string is calculated as a font box.
[0170]
Step S4-2-3-2B: Check whether the pick window and the rectangle obtained in Step S4-2-3-1B geometrically interfere with each other (Step S4-2-3-3-3B). If it is determined that there is a hit, it is determined that there is a hit (step S4-2-3-4B), and if it is determined that there is no interference, it is determined that there is no hit (step S4-2-3-5B).
[0171]
Also according to this embodiment, substantially the same effect as that of the first embodiment can be obtained.
[0172]
[Fourth Embodiment]
Next, a fourth embodiment based on the drawing instruction apparatus according to the first and second embodiments described above will be described. In the following description, the description similar to that of the first embodiment will be omitted, and the description will focus on the characteristic part of the present embodiment.
[0173]
The drawing instruction apparatus according to the present embodiment is different from the first embodiment in which the process in step S4-2-3 is performed according to the flowchart shown in FIG. 27 according to the flowchart shown in FIG.
[0174]
In FIG. 27, step S4-2-3-1C: Estimates the data amount of the contour figure of the image when the element is displayed. At this time, if the amount of data is too large, the interference determination by the image bitmap uses a lot of resources and the calculation cost is high, so the amount of data is first estimated from the original element data.
[0175]
Steps S4-2-3-2C to S4-2-2-3C: The amount of data estimated in Step S4-2-3-1C is compared with a predetermined amount (Step S4-2-3-3C). As a result, when the data amount is smaller than the predetermined amount, each pixel of each bitmap image of the contour graphic and the pick window is the same as step S4-2-3-2 (FIG. 22) in the first embodiment described above. Hit processing is performed by performing interference determination for each (step S4-2-3-3-3C). On the other hand, when the estimated data amount is equal to or smaller than the predetermined amount, interference determination is performed geometrically by the same procedure as that of the flowchart of FIG. 25 in the second embodiment described above (step S4-2-3-4C).
[0176]
Interference determination using a bitmap can perform precise interference determination in consideration of printing attributes, etc., although resources and calculation costs are used. On the other hand, the geometrical interference determination can be performed with a small amount of resources and a low calculation cost, although the accuracy is slightly impaired. According to this embodiment, the above two processes are adaptively switched by estimating the data amount of the contour graphic of the display image of the first element.
[0177]
Also according to this embodiment, substantially the same effect as that of the first embodiment can be obtained.
[0178]
[Fifth Embodiment]
Next, a fifth embodiment based on the drawing instruction apparatus according to the first embodiment described above will be described. In the following description, the description similar to that of the first embodiment will be omitted, and the description will focus on the characteristic part of the present embodiment.
[0179]
The drawing instruction apparatus according to the present embodiment is different from the first embodiment in which the process in step S9 is performed according to the flowchart shown in FIG. 28 according to the flowchart shown in FIGS.
[0180]
In FIG. 28, step S9-1A: the selection element candidates overlap each other and the operator may have difficulty in selection, so that the selection element candidates are temporarily shifted in position so as not to overlap temporarily (FIG. 28). 18). A more specific procedure may be performed according to the flowchart shown in FIG. 29, for example.
[0181]
In FIG. 29, Step S9-1A-1, Step S9-1A-2: A circumscribed rectangle of each overlapping element is calculated, and an appropriate distance indicating the distance between the elements when the overlapping graphic is displayed while being shifted is displayed. Set the margin value.
[0182]
Step S9-1A-3: The circumscribed rectangle of each element around the input coordinates can be arranged vertically and horizontally with the circumscribed rectangle of the other elements by the margin value set in step S9-1A-2. The movement amount of each figure is calculated.
[0183]
Step S9-1A-4, Step S9-1A-5: It is determined whether all the graphic elements that are the selection element candidates can be accommodated in the screen. As a result of the determination, if all the graphic elements are accommodated, step S9-1A- If not, the step S9-1A-5 allows a negative value, and recalculates the movement amount of each figure so that the margin value is reduced to fit within the screen. Alternatively, the display scale of the screen is reduced so that all the elements that are the selection element candidates can fit within the screen.
[0184]
Step S9-1A-6: Each figure is temporarily rearranged according to the obtained movement amount.
[0185]
Next, returning to the description of FIG. Step S9-2A: Each graphic element whose display position is temporarily shifted as described above is temporarily put into a special display state such as high-intensity display, special color display, or blinking so that the operator can easily understand.
[0186]
Step S9-3A: Coordinates are input by a pointing device such as the mouse 12 so that the operator can select a desired graphic element from the selection element candidates displayed as described above.
[0187]
Steps S9-4A to S9-7A: In this embodiment, a pick process that does not have the premise that there are a plurality of selection elements as described in the first embodiment is performed. That is, if there is a selected figure as a result of the pick process, it is set as the selected figure (step S9-6A). On the other hand, if there is no selected figure, error processing such as causing the user to input again as an error is performed (step S9-7A).
[0188]
Step S9-8A: The element in the special display state is temporarily shifted in the process of Step S9-2A to return to the original state.
[0189]
Also according to this embodiment, substantially the same effect as that of the first embodiment can be obtained.
[0190]
[Sixth Embodiment]
Next, a sixth embodiment based on the drawing instruction apparatus according to the first embodiment described above will be described. In the following description, the description similar to that of the first embodiment will be omitted, and the description will focus on the characteristic part of the present embodiment.
[0191]
FIG. 30 is a flowchart showing the procedure of pick processing in the sixth embodiment. Steps S1 to S6 perform the same processing as steps S1 to S6 of FIG. 1 in the first embodiment. That is, if at least one graphic element is hit in step S6, that graphic element is set as the selected element. This enables a quick selection process.
[0192]
Step S11, Step S12: If there is no hit in the determination in step S5, it is determined in step S11 whether there is a graphic element that may still be selected, as in step S7 in FIG. As a result of the determination, when there is a graphic element that may still be selected, the process returns to step S2, and when there is no graphic element, it is determined that there is no selected element in step S12.
[0193]
Also according to this embodiment, substantially the same effect as that of the first embodiment can be obtained.
[0194]
According to each of the embodiments described above, pick processing with excellent operability and considering print attributes is realized. Also, although pick processing is usually performed based on display data including precise print attributes according to the amount of calculation resources of the drawing instruction device, pick processing is performed with simple processing when the amount of resources is insufficient. Thus, appropriate processing according to the situation can be performed.
