Description

Text display method, search method and display device

The present invention relates to character display and retrieval, and more particularly to a display method for displaying characters in a writing order and a retrieval method for retrieving information in a text word. Background technique

Text is a tool for information exchange between people, and the glyph of words is the external expression of words. People realize the understanding of words through glyphs. When using a computer to implement text processing, it is necessary to solve how to input, save, display, retrieve, and print text in a computer system. Regardless of the above operations, the core is related to the text font used in the computer.

A text font is a description of a text glyph in a computer. It is a collection of text glyphs represented in a computer. When the user processes the text, he or she will eventually need to call the information in the text font to display the text on the computer screen or at the print terminal. In the prior art, according to the storage method of the characters in the text font, the character font can be divided into a dot matrix font, a vector font library, a curve font library, a centerline font library, etc., but in any of the above text fonts, when storing a text , the text is stored as a graphic or image element as a whole. For example, taking the "Zhang" word in Chinese characters as an example, in the dot matrix font, the image data of the entire glyph represented by dots is stored, and in the vector font library, the curve font library, and the centerline font library, the whole is stored. A graphical description of the glyph. Each font does not store information about a radical or a stroke in the text.

In the prior art, the processing of characters is performed in various units such as display and printing in units of words. However, in practical applications, there is also a need to process information within the word. Still taking Chinese characters as an example, Chinese characters have radicals, have a fixed number of strokes, and have a prescribed stroke order when writing. The above information in Chinese characters cannot be reflected in the existing Chinese character library, thus affecting the further open use of Chinese character information. For example, if the user needs to output a certain Chinese character one by one in the order of strokes, on the basis of the existing Chinese character library, it is necessary to extract the outline or skeleton of the stroke of the Chinese character to be output, thereby obtaining stroke information, and then displaying the Chinese characters. The strokes are output in order, and the Chinese characters cannot be directly output according to the information of the existing Chinese character library in the order in which the strokes are written. Similarly, users cannot rely on existing Chinese character libraries to directly search for Chinese characters with a certain radical. Defective Further use of the text.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which:

1 is a schematic view showing a direction division of a two-dimensional space involved in the character display method of the present invention;

2 is a schematic view of a character display method of the present invention. detailed description

The invention will be further described below in conjunction with the drawings and specific embodiments.

In the following embodiments, the character display method of the present invention will be specifically described by taking a Chinese character as an example. Before describing the character display method of Chinese characters, it is necessary to explain the data structure and storage method of the Chinese character library involved in the display of Chinese characters.

Based on the existing Chinese character library, the present invention proposes a new Chinese character library, in which the in-word information of the Chinese character is stored in the data structure of the Chinese character library. Specifically, first need Divide a Chinese character into basic elements, and record two pieces of information of each basic element, namely glyph description information and direction. In one embodiment of the present invention, the basic element involved may refer to a stroke or a combination of strokes in a stroke, for example, for a stroke Ί", which may be a basic element, and for a stroke "", Then it can be divided into two basic elements, which are "one" and "1" respectively. As can be seen from the above examples, the strokes in the basic elements usually have the same direction, and the structure is relatively simple, but the invention is not limited to the above. Description.

The above information of the basic element may describe the basic element in more detail, wherein the glyph description information is used to represent the shape of the basic element, and the glyph description information also exists in the existing Chinese character library. However, a difference from the present invention is that only the glyph description information of the entire word is stored in the existing Chinese character library, and in the present invention, the glyph description information of the basic elements of the character is stored. There are various manifestations of glyph description information, such as dot matrix mode, vector mode, curve mode, center line mode, skeleton mode, and contour mode in the prior art, which can be used to represent glyph description information. The direction is used to indicate the direction of travel of the stroke in the basic element. In one implementation, the two-dimensional space can be divided into eight directions. As shown in FIG. 1, the eight directions are a, b, c, d, e, f, g, h respectively indicate that the direction of the basic elements can be described by the above letters. For example, for the basic element "one", its direction of travel is horizontal from left to right, so the letter b can be used to indicate its direction. In practical applications, in order to improve the accuracy of the description of the stroke direction of the strokes in the basic elements, the direction of the basic elements can also be explained by the angle method.

The information of the basic elements is not limited to the above two pieces of information, and in another embodiment, the information of the basic elements may further include speed information. The speed is used to indicate how fast the basic elements are when writing. As a basic common sense, we know that Chinese characters have a unique writing rhythm during writing. The speed of writing on one pen is slightly faster, and the writing speed on another pen is slower. The speed information in the basic elements is used. To record the speed of the basic element when writing. In particular, in a basic element, there is also a difference in the speed of writing between different segments. Therefore, the velocity information of a basic element can be segmented. In addition, since the actual writing process, after writing a basic element in a stroke or a stroke, there may be a corresponding pause. Therefore, the speed information may also include information on the length of the pause between the basic elements. In the following, taking "Zhang" in Chinese characters as an example, the intra-word information of Chinese characters in this embodiment is as in the Chinese character library. How to store the corresponding instructions.

First of all, the basic elements of the Chinese character "Zhang" are split. According to the above splitting principle, the following basic elements can be obtained in the order of writing: "_", "'", "-", "'", "- ", "/",

Then, in the Chinese character library, the in-word information of the Chinese character "Zhang" is stored. In the storage process, the basic unit stored is not the entire word, but the basic elements of the word according to the above description, all basic The storage information of the elements is stitched into a complete word. The following table 1 is used to indicate the data structure of the "Zhang" word when it is stored.

Table 1

In the above table, the information of each basic element in the "张" character is described, wherein the dot matrix/vector/curve/centerline data information is specific information describing the shape of the basic element by numbers, and the information is It has been in the prior art and will not be repeated here. It should be noted that since the basic elements "-" and "'" in the above table are obtained from a basic stroke, when numbering these two basic elements, "0/0", "0" is used. /1 " is numbered to indicate the connection between the two basic elements, and it is also convenient to use the number

"0" unified representation of strokes " ". For the basic elements "' ", "-", ",", and "b,

'ν', there is also such a division. In addition, as mentioned in the foregoing description, the glyph description information can be expressed in various ways, such as the common dot matrix definition method and the contour definition method. (including linear and curved), skeleton definition, centerline definition, etc., it covers various typical representations, such as TrueType. In view of the need for multiple representations of glyph description information, in view of the need for compatibility, a plurality of data structures as described in Table 1 may be defined for one Chinese character in a Chinese character library, and used in different data structures. Different ways represent glyph description information. This can enable the user to select an appropriate glyph description information representation according to the actual application, and provide users with a variety of options.

In the above table, in addition to the number indicating the writing order of the strokes, the stroke type information represented by numbers is also included, such as "5" at the lower left of the first row of Table 1. In the "Modern Chinese General Character Stroke Specification" issued by the National Language and Literature Working Committee, the various strokes of Chinese characters are divided into five basic types, which are represented by horizontal, vertical, 撇, point, and fold, respectively. Strokes can be classified as corresponding strokes. For example, the mention can be returned to the horizontal, the 捺 can be returned to the point, the vertical hook is classified as the vertical, and various folding pens (such as horizontal folding hooks, horizontal folding hooks, vertical bending hooks, etc.) can be assigned to the fold. Use 1, 1, 3, 4, and 5 to represent the five basic types of horizontal, vertical, 撇, point, and fold. Although the basic type information of strokes is only indicated in the above table, in the specific application, it can be further divided under five basic types, for example, 1 / 0 for horizontal, 1 / 1 for lifting, 2 for / 0 means vertical, 2 / 1 means vertical hook, etc., to get further stroke type information. The addition of stroke type information facilitates the retrieval, classification, sorting, and display of strokes of a particular stroke type in Chinese characters.

In addition, in the above table, in addition to adding the type information of the stroke, the corresponding stroke speech information or its encoding information may be added according to the type information of the stroke, and the stroke information or the encoding information thereof may be used according to the stroke information, and may be in the subsequent display process. In the middle, the stroke of the stroke is read while the stroke is displayed.

In the above embodiment, the respective strokes in the Chinese characters are sequentially stored in the order of writing, but in other embodiments, the individual strokes in the Chinese characters may not be sequentially stored in the order of writing. For the case where the stroke information is not stored in the order in which the strokes are written, as long as a pointer pointing to the next stroke in the writing order is added to the data structure of each stroke in the storage process, the sequential display of each stroke in the Chinese character can also be realized. .

Based on the data structure described in Table 1, in another embodiment, a call to this data structure can be implemented by an index table. Using this index table, further classification and storage of the structure information in Chinese characters can be realized. For example, since most Chinese characters belong to a phonogram, in the above index table, the numbers of the strokes in the kanji can be stored separately according to the shape and the side of the sound, thereby distinguishing the shape of the Chinese character from the side of the sound. As shown in Table 2 below, each stroke in the aforementioned "Zhang" word is stored as follows: Chinese character coded next to 0, 1, 2 sounds 3, 4, 5, 6 strokes 7

Table 2 In the above table, the Chinese character encoding may be the Un i code encoding of the Chinese character or the GB encoding, the Un i code corresponding to the Chinese character is 5 F20, and the corresponding GB encoding is D5C5.

In addition to the above information stored in Table 2, an interval parameter can be added between the stroke numbers in the index table to indicate the pause of the stroke when writing. Of course, for Chinese characters that do not belong to the phonogram, such as a single character, you can store the Chinese characters according to the form and the side of the sound according to the above table, as long as the serial number of the stroke and the total number of strokes are recorded. In addition, as mentioned in the foregoing, a plurality of data structures as shown in Table 1 can be defined for a Chinese character so that the glyph description information can be represented in various ways, and therefore, it is also possible to add one to the data structure described in Table 2. The option to represent the referenced data structure. According to this option, choose which way to display the Chinese characters in a stroke, or you can choose to display the Chinese characters as a whole according to the existing common methods. Considering the need for in-word retrieval, it is also possible to add the side or side of the text to the above index table as a separate text encoding. For example, for "Zhang", we can add the encoding of the "bow" and "long" words to the index table. In addition, voice or speech coding information of the text may be added to the index table so that the speech of the text can be read during subsequent text display. There may be more than one voice or speech-encoded information added to the index table, which helps to represent and distinguish between multi-phonetic words.

In the above description, the Chinese character library involved in the present invention has been described by taking the "张" character as an example. For other Chinese characters, the corresponding storage in the Chinese character library can be realized by the above method. In summary, the Chinese character library involved in the present invention creates conditions for the Chinese character to be displayed by stroke by adding information in the Chinese character.

Based on the above Chinese character library, Chinese characters can be further processed. In the process of displaying Chinese characters, the Chinese characters can still be output according to the existing method according to the existing method, or the Chinese characters can be sequentially output according to the stroke order according to the information in the Chinese character words stored in the Chinese character library. The following still uses the "张" character as an example, and the display method of the present invention will be described correspondingly with reference to FIG.

Step 1 0. Using the Chinese character encoding, an index table of the Chinese character is obtained. For a specific Chinese character, there is a unique Chinese character encoding. Therefore, according to the encoding, the corresponding index table can be obtained. The index table described in this step is shown in Table 2.

Step 20: Select a display mode of the Chinese character. If the Chinese character is displayed as a whole, the Chinese character library part that describes the Chinese character glyph is called from the Chinese character library, and then according to the display method of the prior art. Display, if the Chinese character is displayed by stroke, proceed to the next step.

Step 30: Select a stroke of the Chinese character in order. Since the strokes of Chinese characters have been numbered sequentially in numbers when stored in the Chinese character library, in this step, the progressive selection can be made according to the numbers from small to large. For example, for the "Zhang" word, its first stroke is represented by 0. Therefore, when the first stroke is selected, the stroke numbered 0 is selected, and when the selection is made later, the number is 1, 2, 3 Strokes, etc.

Step 40: Call the glyph description information of the current stroke. Since a stroke may be divided into multiple basic elements, when the glyph description information of the current stroke is called, the glyph description information of all the basic elements in the stroke is actually called. After obtaining the corresponding coding of the stroke from the previous step, the specific information of the basic elements in the stroke can be obtained from the corresponding data structure (such as Table 1), including the glyph description information, the direction information and the speed information. In this step, the call is invoked. Glyph description information. As mentioned above in the description of the Chinese character library, the glyph description information of the Chinese character is represented by the dot matrix method or the vector mode or the curve mode or the center line mode or the skeleton mode or the contour mode in the prior art, so the glyph description is called. When information is used, the corresponding glyph description information description method is adopted according to the representation manner of the glyph description information.

Step 50: Determine a representation manner of the glyph description information of the stroke. If the glyph description information is expressed in a dot matrix manner, step 70 is directly performed; if other types of representation manners are performed, the next step is performed;

Step 60: Perform a rasterization operation on the basic elements in the current stroke according to the glyph description information. A rasterization operation is the process of converting a primitive into a two-dimensional image. The specific implementation of rasterization operations is a mature prior art.

Step 70: Perform a drawing operation on the current stroke. Drawing operations on strokes include static display, dynamic display, and printing. The dynamic display is to display the strokes of Chinese characters according to the writing rules. As mentioned in the foregoing, the stroke can be divided into a plurality of basic elements, so that in the dynamic display process of the drawing operation, the corresponding drawing is performed in the order of the basic elements in the stroke. In the process of painting, you first need to know the writing order. This writing order can be obtained by the direction information of the basic elements. Secondly, in the process of drawing operation, the writing rhythm of Chinese characters should be reflected. This writing rhythm can be passed through the basic elements. The speed information is obtained. The static display and printing in the drawing operation have existed in the prior art, and the description will not be repeated here. As mentioned in the foregoing, the glyph description information of the stroke has multiple representations. In the process of drawing operation, for the representation mode that needs to be rasterized, the drawing operation is performed on the basis of the rasterization operation, The lattice mode of the rasterization operation directly performs the drawing operation. The specific implementation process of the drawing operation for different tables The way is the same. In addition, when the current stroke is drawn, if it is a dynamic display process in which the Chinese characters are gradually displayed in the order in which the strokes are written, the voice information of the strokes can also be read out simultaneously during the display.

Step 80: Determine whether the current stroke is the last stroke of the current Chinese character, and if so, end the display process of the current Chinese character; otherwise, call the next stroke in the Chinese character, and then re-execute step 30. In this step, before calling the next stroke in the Chinese character, a certain calling condition can also be set. For example, after obtaining one input information of the user, the next stroke is called, so that the Chinese character can be made in the display process. The output of the stroke is displayed under the control of the user, and the strokes are implemented in sequence. In addition, the call condition can also be used to selectively display a part of the Chinese character (such as a radical). After setting the calling condition, in this step, it is also necessary to judge whether the next stroke to be called satisfies the termination condition in the calling condition, and if it is satisfied, the display is terminated.

In the above embodiment, the display method of the characters is described by taking Chinese characters as an example, but those skilled in the art should understand that similar processing can be performed for other types of texts to further implement the information in the characters. operating.

Corresponding to the text display method of the present invention, the text display device can also be used to implement the idea of the present invention. The device includes a text information unit, a stroke selection module, and a stroke drawing module. The text information unit is used for storing Information about the basic elements obtained by splitting the text according to strokes;

The stroke selection module is configured to, in the process of sequentially displaying according to the strokes, call the corresponding stroke information from the text information unit, and determine whether the current stroke is the last stroke of the text or whether the next stroke satisfies the call termination. Condition

The stroke drawing module is configured to complete the depiction of the stroke according to the information of the stroke.

The device further includes a display mode selection module, and the display mode selection module is configured to select a display mode of the text.

The stroke drawing module includes a glyph description information representation mode determining unit, a rasterizing operation unit, and a drawing operation unit. The glyph description information representation mode determining unit is configured to display the glyph description information of the basic element. Judging, according to the judgment result, determining whether to call the rasterization operation unit or the drawing operation unit;

A text library can be obtained by combining the above text information units.

The above text display device has a more display mode than the existing text display device. More choices give users more flexibility.

The text display device can also have typesetting and printing functions.

In addition to displaying the characters in sequence in accordance with the strokes, the present invention can also perform retrieval of specific conditions based on the in-word information of the characters. The following still uses Chinese characters as an example to illustrate this search process.

As mentioned in the foregoing description, the in-word information contained in the Chinese character library includes the number of strokes of the Chinese character, the basic elements constituting the Chinese character, and the like. Therefore, when searching, it is possible to search for the search conditions such as the number of strokes of Chinese characters and the radicals of Chinese characters based on the information in these words. It should be specially noted that the radical heads involved in the present invention include not only the radical heads specified by the National Language Working Committee, but also the results obtained by splitting or combining the prescribed radicals or the user. A defined smaller unit of constituting the radicals is defined. Further, the radical portion described in the present invention can be further classified into the aforementioned shape and side by sound according to the action played in the text.

In one embodiment, the search condition set by the user is to find a Chinese character with a stroke number of 7, and according to the retrieval condition, find an index table of all the Chinese characters in the Chinese character library. It can be seen from the index table shown in Table 2 that the description information of the number of strokes of Chinese characters has been included in the index table, so that all Chinese characters with a stroke number of 7 in the Chinese character library can be extracted, and then the aforementioned Chinese character display method is called. Or the text display method in the prior art displays all the Chinese characters that meet the conditions in a specified manner. The "张" word mentioned in the previous example satisfies this search condition and is therefore displayed as a search result. Further, if there are more than one search result for a certain number of strokes, the search results may be sorted according to the stroke type information stored in the above Table 1, so that all the search results can be displayed in accordance with the stroke type during the display process. In this embodiment, the user sets the number of strokes in the search condition to a specific value. In other embodiments, the number of strokes in the search condition may be set to a certain value range, such as the number of strokes found is greater than All Chinese characters of 7, or all Chinese characters with a stroke count less than or equal to 7. Referring to the foregoing description, the retrieval of this search condition can also be achieved. In addition, when the search result includes a plurality of stroke numbers, the number of strokes may be first sorted, then the Chinese characters having the same stroke number are sorted according to the stroke type information, and finally the sorted search results are displayed.

In yet another embodiment, the user sets the search criteria to find all Chinese characters having a certain radical. In the index table shown in Table 2, the Chinese characters have been distinguished according to the shape and the side of the sound, and the code corresponding to the radicals is recorded in the field next to the shape and the sound. Therefore, in the retrieval process, the encoding of the radical portion to be searched is compared with the encoding of the radical portion recorded in the index table, and the Chinese character satisfying the retrieval condition can be found, and then the foregoing display method or prior art is invoked. The text display method in the display shows the search results. Take the aforementioned "Zhang" as an example, "Bow" as the shape, "Long" For the sound, if the code "1 122" is used as the "bow" of the radical, and the code "4455" is used as the "long" of the radical, then when the user wants to retrieve the "bow" as the radical, in the Chinese character library Find the code "1 122" in the index table of each Chinese character, and you can find the Chinese character with the radical "bow". It should be noted that the encoding used to represent the radicals here is preferably different from the encoding of the radicals as a single Chinese character, that is, the encoding of the "bow" as the radical is preferably not the GB encoding of the "bow" word or Un i code code. In addition, when the search result is displayed by the foregoing display method, the radical portion to be retrieved may be displayed in one manner (such as a certain color), and the Chinese character may be displayed in another manner (such as another color). The part outside the radical is to be searched.

In another embodiment, the user may further set the search condition when searching for the radical radicals, for example, searching for all Chinese characters in the Chinese character as the side of the radical "bow". The word "bow" is in the form of "Zhang", which may be used as a sound in other Chinese characters. Therefore, based on this retrieval condition, a more accurate search of the information in the Chinese character can be made. In realizing this retrieval, in the index table of all Chinese characters in the Chinese character library, only the code "1122" is found in the shape side portion, and then the above display method is called to display the output of the condition satisfying the condition. If you want to retrieve all the Chinese characters next to a certain radical in the Chinese character, the operation is similar.

In still another embodiment, the recursive definition of the shape or the side of the index table shown in Table 2 is to further split the radicals represented by the shape or the side of the sound to generate a new shape and side. . For example, for the word "湖", the sound of "Hu" can be further divided into "Ancient" next to the sound and "Month" next to the sound. Through the above splitting, the user can be provided with a more fine-grained search for the radicals. The more fine-grained retrieval of the radicals can be achieved by recursive retrieval.

In still another embodiment, the user can also set a combined search condition to obtain a more accurate search result. For example, combine the two search conditions of the radicals and the number of strokes mentioned above. In the index table shown in Table 2, an item for recording the number of strokes of the radical portion can be added in the field next to the shape and the side of the sound. When the corresponding search result is obtained from the radicals according to the foregoing method, the search result may be further searched according to the number of strokes. For example, after retrieving the radical "bow", the resulting search results include multiple results such as "zhang", "strong", "bomb", and "chord". If you further enter the search condition that the number of remaining strokes is "4", you can eliminate the rest of the search results except the "Zhang" word. Similar to the previously mentioned stroke number retrieval, in other embodiments, the number of strokes as further retrieval conditions may be a numerical range in addition to a specific numerical value.

The above is an example of how to implement information retrieval in text words by using Chinese characters as an example. However, those skilled in the art should understand that, in combination with the ideas embodied in the above description, the same can be achieved. Retrieval of in-word information of other characters other than Chinese characters.

It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and are not limiting. While the invention has been described in detail herein with reference to the embodiments of the embodiments of the present invention Within the scope of the claims.
