Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outline font creating apparatus used for a display, a printer, a photocomposer, and the like, and more particularly, to correction of a horizontal line or a vertical line in an outline font.

[Prior Art] Conventionally, outlines of character symbols and the like are stored as outline fonts, and after processing such as enlargement / reduction / rotation is performed and then developed into a dot pattern, various character sizes and inclinations from one type of font are obtained. Some fonts output high-quality fonts with. As an apparatus for creating the outline font, an outline font is created by reading a handwritten character with a scanner and converting it into an outline font, or by inputting the coordinate values of the end points of each component line constituting the outline using coordinate value input means. was there. When correcting the outline font, the outline is displayed on a display, and the coordinate values of each end point of the constituent lines of the outline are changed.

[Problems to be Solved by the Invention] However, in the conventional outline font creation device, when displaying the entire character on the display device, the display is often performed in a reduced size. Was corrected separately, so that the horizontal and vertical lines were not always corrected. It is also very difficult to unify a plurality of line segments on the same horizontal line and vertical line. Also,
In order to solve this, when enlarged display is performed, both ends of a line segment and a plurality of line segments to be unified are not displayed at the same time, and it is also difficult to correct a horizontal line and a vertical line accurately. Further, even if a high-resolution display device is used, it is extremely labor-intensive to find subtle inclinations of line segments and deviations in the positions of the line segments.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and has as its object to provide an outline font creating apparatus capable of efficiently correcting a horizontal line or a vertical line of an outline font.

[Means for Solving the Problems] In order to achieve this object, an outline font creation device of the present invention displays outline font input means for inputting outline fonts such as characters and symbols, and displays the input outline font. Display device, reduced display means for reducing the display size in which the outline font is displayed on the display device based on the resolution of the display device and the resolution of the outline font, and the reduced display means to the display device. Reference point designating means for designating one of the end points of each constituent line constituting the outline of the outline font displayed as a reference point as a reference point; range designating means for designating a plurality of end points in the outline as points to be corrected;
Correction means for matching the horizontal or vertical coordinate values of all the end points included in the range designated by the range designation means with the horizontal or vertical coordinate values of the reference point designated by the reference point designation means are provided.

[Operation] According to the present invention having the above-described configuration, the outline font such as characters and symbols input by the outline font input unit is reduced by the reduction display unit based on the resolution of the display device and the resolution of the outline font. Is displayed in a reduced scale on the display device, the reference horizontal or vertical coordinate value is determined from the reference point specified by the reference point specifying means, and the end point of the line segment included in the range specified by the range specifying means is corrected. It is a point to be done. Then, the correction means corrects the horizontal or vertical coordinate value of the point to be corrected to the coordinate value of the reference point.
That is, if one end point of a certain straight line segment is used as a reference point and the other end point is included in the range specification, the straight line segment is corrected to a horizontal or vertical line segment. Further, when both ends of a plurality of straight lines are included in the range specification, all the straight lines are corrected so as to coincide with the same horizontal or vertical coordinate value.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the outline font creation device of the present embodiment. This apparatus displays a CPU (central processing unit) 1 for controlling the entire apparatus, a ROM 3 for storing a control program of the CPU 1, a RAM 4 for storing outline font data to be created, and the shape of the outline font. Display device 2 and mouse 5
And so on.

In addition to the outline font shape 8 being created as shown in FIG.
Is displayed. The mouse 5 is provided with a mouse cursor control mechanism 6 and an instruction button 7. By operating the mouse car soul control mechanism 6, a mouse cursor 14 is newly created in the menu 9, one point correction 11, vertical line correction. The mode is moved to the item 12 and horizontal line correction 13, and the above modes are set by pressing the designation button 7.

In the new creation mode, text /
A symbol or the like is read and its outline is displayed on the display device 2. The one-point correction mode is a mode in which the coordinates of only one end point of the constituent line of the outline displayed on the display device 2 are changed. In the vertical line correction mode and the horizontal line correction mode, horizontal coordinate values and vertical coordinate values of a plurality of the end points are collectively corrected to desired coordinate values. For details, in the state of vertical line correction mode or horizontal line correction mode,
By moving the mouse cursor 14 over an arbitrary end point in the outline and pressing the designation button 7, the reference point of the horizontal coordinate value is set in the vertical line correction mode according to the mode.
In the horizontal line correction mode, the reference point of the vertical coordinate value is specified. Further, in this state, by moving the mouse cursor 14 and pressing the designation button 7 at any two points on the outline of the display device 2, the end points included in the rectangle having the two points as diagonal vertices are displayed. The horizontal coordinate value (in the case of the vertical line correction mode) or the vertical coordinate value (in the case of the horizontal line correction mode) is designated as a correction range, and is matched with the coordinate value of the reference point.

Next, the present embodiment will be described with reference to the creation of an outline font of "A". First, the shape 8 shown in FIG.
Is created on the display device 2. Due to the difference between the resolution of the display device 2 (500 × 500) and the resolution of the outline font to be created (1000 × 1000), the display is reduced to half. In this case, as shown in FIG. 3 which is an enlarged view of a portion 15 of FIG. 2 and the coordinate values of each end point are added, even if the display device 2 is modified to be displayed as a vertical line 17 on the display device 2. Horizontal coordinate values of both end points 18 are 650 and 6
There is a possibility that it is shifted by 1 as in 51, and there is no guarantee that the line segment 17 is exactly a vertical line. Similarly, there is no guarantee that the horizontal coordinate values of a plurality of line segments 17 and 19 displayed on the display device 2 so as to have the same horizontal coordinate value match.
Even if the plurality of vertical lines 19 and 20 are displayed at slightly different horizontal coordinate values on the display device 2, it is very difficult for the user of the present device to find them.

Then, by operating the mouse 5, the mouse cursor 14 is moved to the vertical line correction 12 of the menu 9, and the designation button 7 is pressed. This operation puts the apparatus in the vertical line correction mode, which is indicated to the operator by the display of the mark 16 on the menu 9. Next, as shown in FIG. 4, the horizontal coordinate value is designated by moving the mouse cursor 14 over the end point 22 of the component line and pressing the designation button 7. The designated horizontal coordinate value is indicated to the operator by the vertical line 21 on the display device 2. Next, the mouse cursor 14 is moved to an arbitrary point 23, the designation button 7 is pressed, and the mouse cursor 4 is moved to another arbitrary point 27.
Is moved and the designation button 7 is pressed, the rectangle 26 having the designated two points 23 and 27 as diagonal vertices becomes the range of the end point to be corrected. As a result, the end point 24 included in the rectangle 26
Is corrected so as to match the horizontal coordinate value 21 of the reference point 22. Therefore, the line segments 25 designated as the reference points or the points to be corrected at both end points are corrected so that they are all vertical and have the same horizontal coordinate value. Similarly, as shown in FIG. 5, the horizontal line segment 30 having the same vertical coordinate is selected by selecting the horizontal line correction mode and specifying a plurality of end points 29 by the end point 28 and the rectangle 31 serving as the reference of the vertical coordinate value. Can be modified.

In the present embodiment, the horizontal or vertical coordinates are input by designating the end points, but the coordinates may be input numerically. Alternatively, a plurality of end points to be corrected may be specified one by one instead of a rectangle. Further, a configuration including a tablet, a light pen, a keyboard, and the like instead of the mouse 5, a configuration in which an external storage device for storing created data is added, and a configuration in which a printer is added as an output device may be adopted.

[Effects of the Invention] As is clear from the above description, according to the outline font creating apparatus of the present invention, since the reduced font display device is provided, the high resolution display device is not particularly required.
Outline fonts with accurate horizontal and vertical lines can be created efficiently.
