Abstract

PURPOSE:To obtain visually excellent output aptitude by providing an attribute to the control point of an outline font and using the same corresponding to an output size. CONSTITUTION:An attribute is provided to the control point of the outline font stored in a pattern data storage means 4 and the attribute optimum to an output character size is used by a control point position judging means 2 judging the output character size indicated by document data and a control point control means 3 controlling the control point on the basis of the output character size is used to develop an outline font on a pattern data developing means 5 and the outline font is outputted to an output apparatus as output data 6. By this method, visually excellent output aptitude from a small size for the text to a large size for a title can be obtained from one character font data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character generation method, and more particularly to an outline character generation method used in a computer phototypesetting device or a pattern drawing device such as a plotter.

[Conventional technology]

Conventionally, in this type of character generation method, information such as the character size, character code, and font of the character image is input into the document data, and based on this information, the outline font stored in the pattern storage means is patterned. The image is expanded by the expansion means and outputted to the output device. For this reason, the output character image is uniformly an image of the character font data installed in the storage device, and the problem remains that optimum visibility according to the output size cannot be obtained.

[Problem to be solved by the invention]

The conventional character generation method described above uniformly processes the pattern data installed in the pattern storage means, so it is possible to change the size and shape of the entire pattern (long, half, italic, etc.) of the characters to be output. etc.) can only be changed. For this reason, computerized phototypesetting devices, pattern drawing devices, and the like have the following drawbacks.

The small font size for the main text is I in Figure 4.

It is not possible to perform ink trap processing such as sumitri, which prevents characters from becoming blurred when printing letters such as J, and ni, and kadodate, which prevents the corners of letters such as A, B, C, and D from curling.

*On the other hand, if a character pattern subjected to ink trap processing is implemented, it will stand out and be visually inferior in large character sizes suitable for headlines as shown in Figure 2.

Therefore, in order to maintain character quality for main text and headings on an output device, it is necessary to limit the output range of character sizes, or prepare two types of fonts with the same design typeface, with and without ink traps, and use font size It is necessary to switch according to

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a character generation method that can provide output suitability with excellent visibility from a small size for main text to a large size for headings using one character font data. There is a particular thing.

[Means for Solving the Problems] The character generation method of the present invention assigns attributes to the control points of the outline font stored in the pattern data storage means, and determines the output character size specified by the document data. The control point position determining means for controlling the control points and the control point control means for controlling the control points according to the output character size develop an outline font in the pattern data development means using the attributes most suitable for the output size, and output the outline font to the output device as output data. It is characterized by output.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Figure 1 is a program diagram of one embodiment of the present invention, Figure 2 is a diagram showing a character pattern drawn using a general outline method, and Figure 3 is a diagram showing a character pattern drawn using a general outline method. FIG. 4 is a diagram showing an outline font suitable for text obtained in this embodiment.

Referring to FIG. 1, character data 1 stores the character size, character code, font, etc. of a document image to be output. Normally, the character pattern stored in the pattern data storage means 4 is developed by the pattern data development means 5 using the character data 1, and is outputted as output data 6 to the output device.

The embodiment shown in FIG. 1 is a system having a control point position determining means 2 and a control point control means 3 for this normal operation, and is shown in FIG. 2 below.

This will be explained with reference to FIGS. 3 and 4.

Character data 1 always stores an output character size. For example, the control point position determining means 2 detects the output character size indicated by the numerical value, which may be a point number or a series.

The output character size to which the ink trap processing is applied is preset in the control point position determination means 2.

For example, if the main text output character size is set to 12 points or less, a numerical value specifying the range is stored.

If the output character size N of the character data 1 is N≦12 points, the control point control means 3 calls the outline font shown in FIG. Expand to.

Further, when the output character size is 12 points <N, the general outline font shown in FIG. 2, which is not subjected to ink trap processing, is developed from the pattern data storage means 4 into the pattern data development means 5.

The outline data stored in the pattern data storage means 4 will now be explained. FIG. 2 shows pattern data that is generally drawn using an outline method. Normally, a bag-shaped outline is drawn starting from the starting point and the ending point returns to the starting point, but in this embodiment, the positions of the starting point and ending point, and the direction in which the outline is drawn are not particularly determined.

At the control point A-, in the X direction,
It is an inflection point that is discontinuous in the direction or in both the X7 directions.

FIG. 3 shows the coordinate points and how they change when this control point is given an attribute. For example, at control point A, -coordinate point a in the outline font of ``boat fishing''.

On the other hand, the coordinate point of al is provided as an attribute for ink trap processing.

For example, among the 8 bits b8 to b1, b8 to b1 are the attributes.
b6 is used for output character size identification, b5 is used for positive/negative identification, b4. b3 is for direction identification, b2. bt is used for movement, and the output character size range and movement amount may be given according to predetermined regularity.

Positive/negative identification means ten directions or one direction with respect to the origin, and direction identification means only the X direction, only the X direction, or both the X7 directions. The attributes for the B-J coordinate points are similar, but coordinates are set in advance for coordinate points that do not require such ink trap processing due to the visibility of the characters, such as E, A, G, and H. There is no need to keep it.

Now, if outline font data subjected to ink trap processing by the control point control means 3 is required, the coordinate point A is moved to the coordinate point al according to the attribute. At this time, the outline data heading to the next control point B is not from the coordinate point al, but only the value shown in the attribute, for example, 1 dot, and after this specified value, it is on the normal outline data of A-1-H. via.

Similarly, the coordinate point B is also moved immediately before the b1 coordinate point indicated in the attribute.

Therefore, the character pattern (
4) and the character pattern without it (FIG. 2) do not differ greatly in the external shape of the outline.

〔Effect of the invention〕

As explained above, the present invention allows control points of outline fonts to have attributes and uses those attributes according to the output size. The effect is that output suitability with excellent visibility can be obtained up to the size.
