Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The text rendering method and apparatus of the present invention are described below with reference to fig. 1 to 3.
Fig. 1 is a schematic flow chart of a text rendering method provided by the present invention, and referring to fig. 1, the method includes steps 101 to 104, wherein:
step 101: responding to a display instruction of a target document, and acquiring an initial font name of characters in the target document aiming at the characters.
Firstly, it should be noted that the execution body of the present invention may be any electronic device for performing text rendering, for example, any one of a smart phone, a smart watch, a desktop computer, a portable computer, etc.
Specifically, the target document refers to a document to be displayed or a document to be text-rendered, and the target document may be an OFD document, a portable file format (Portable Document Format, PDF) document, a Word document, a picture format document, or the like. The display instruction refers to an instruction for displaying and presenting the target document. The text is a tool for recording language, which may be chinese, english, french, etc. Font names (family name values) refer to the names of fonts, such as Song's body, regular script, and the like. The initial font name refers to the font name of the text acquired from the document information of the target document.
In practical applications, when a user opens a target document through a document display system (a document display or document editing tool), the execution body receives a display instruction of the target document accordingly. In response to the presentation instruction, the execution body initiates a process of rendering text in the target document.
Under the condition that the target document contains characters, acquiring initial font names of the characters aiming at the characters in the target document: the Font identifier of the text, such as Font ID (Font ID), is acquired first, and the Font name corresponding to the Font identifier is identified as the initial Font name.
It should be noted that there may be a plurality of characters in the target document. At this time, each text in the target document can be respectively rendered according to the text rendering method provided by the invention; all the characters in the target document can be rendered according to the character rendering method provided by the invention; the text of each area in the target document, such as the text in each paragraph, the text in each row, and the like, can be rendered according to the text rendering method provided by the invention; but may be others, and the invention is not limited in any way.
Step 102: and matching the initial font name with each first character code in a first association table to determine the initial character code, wherein each first font name and the corresponding first character code are stored in association in the first association table.
Specifically, the first font name is the collected font name. The character code may be a codeplage value or a charset value. The first character encoding is a character encoding of a first font name.
In practical application, on the basis of obtaining the initial font name of the text in the target document, further, determining initial character coding according to the initial font name and the first association table: and searching a first character code corresponding to the initial font name from the first association table as an initial character code.
Illustratively, the codeplage value is searched from the table a (first association table) using the family value of the font, and the searched codeplage value is used as the initial character code.
It should be noted that, before the initial font name is matched with each first character code in the first association table, the method further includes:
collecting a plurality of first font names, and searching first character codes of the first font names;
and storing each first font name and the corresponding first character coding association thereof into the first association table.
In practical application, the first font names are collected as much as possible, then the character codes of the first font names, namely the first character codes, are searched, and the first font names and the corresponding first character codes are associated and stored in the first association table.
For example, the font names, i.e. the first font names, are collected as much as possible on the internet and in operation, then the codeplage values corresponding to the collected first font names are searched, and the first font names and the corresponding codeplage values are recorded in a first association table in the database, such as table a.
In addition, whether the fonts of the characters in the target document are embedded fonts can be judged according to the initial font names, if yes, the characters are rendered according to the embedded fonts, if not, the initial font names are matched with the first character codes in the first association table, and an initial character code body is determined, namely the characters are rendered by using the fonts contained in the document display system.
Step 103: and under the condition that the second association table does not contain the initial font names, matching the initial character codes with the second font names in the second association table to determine target font names, wherein the second association table is stored with the second font names and the corresponding second character codes in the document display system in an associated mode.
In particular, a document presentation system refers to a tool or software program for presentation or editing of a document. The second font name is a font name contained in the document presentation system. The second character encoding is a character encoding of a second font name.
In practical application, on the basis of determining the initial character code, further, judging whether the second association table contains the initial character code, if not, indicating that the installation package of the corresponding font in the target document is not installed in the document display system, namely, rendering the text according to the corresponding font in the target document is not possible.
Since the character codes are the same and different fonts, the fonts are relatively more similar, namely, the characters are rendered by using the same and different fonts, and the shapes of the characters are more similar, the target font name can be determined according to the initial character codes and the second association table: and searching a second font name corresponding to the initial character code from the first association table as a target font name.
Illustratively, the initial character is encoded as a codeplage value: 369, searching at least one second font name with a code value of 369 from a table b (second association table), namely a font name set, and screening one second font name from the font name set as a target font name according to a set screening rule. The setting of the filtering rule may be to use any one of the second font names as the target font name, or use the first second font name as the target font name, or the like.
Step 104: and rendering the text according to the font corresponding to the target font name.
In practical application, on the basis of determining the target font name, setting the font of the characters as the font corresponding to the target font name, and rendering the characters, thereby displaying the target document.
According to the character rendering method provided by the invention, the initial font name of characters in the target document is obtained by responding to the display instruction of the target document; then, the initial font name is matched with each first character code in the first association table to determine the initial character code, so that the character codes are classified; under the condition that the second association table does not contain the initial font names, the initial character codes are matched with the second font names in the second association table, the target font names are determined, the similarity between the fonts corresponding to the target font names and the fonts corresponding to the initial font names is improved, the fonts corresponding to the target font names are more suitable, and the rendering accuracy of the document is improved after rendering; the format and style of the document can be better reserved, so that the rendering effect of the document is improved; and the readability and the aesthetic degree of the document can be improved by rendering with the proper fonts, so that the use experience of a user is improved.
In one or more optional embodiments of the present invention, in a case where the second association table does not include the initial font name, the matching between the initial character code and each second font name in the second association table is performed to determine a target font name, and the specific implementation process may be as follows:
judging whether the initial character codes exist in the second association table or not under the condition that the second association table does not contain the initial font names;
if yes, determining a second font name corresponding to the initial character code as a target font name;
if not, determining the default font name of the document display system as the target font name.
Specifically, the default font name refers to the name of a font that the document presentation system or program is carrying.
In practical application, if the second association table does not contain the initial font name, it is first confirmed whether the initial character code exists in the second association table.
If the character codes exist, the document display system is provided with an installation package of a character font similar to the character font in the target document, at least one second character font name corresponding to the initial character codes can be searched from the first association table, then the similarity between each second character font name in the at least one second character font name and the initial character font name is determined, and the second character font name corresponding to the highest similarity is used as the target character font name; or determining any one of the at least one second font name as the target font name; or determining a first one of the at least one second font name as the target font name.
If the default font name is not available, the default font name of the document display system is determined as the target font name, and the installation package of the font similar to the font of the Chinese character in the target document is not installed in the document display system.
Therefore, whether the initial character encoding result exists in the second association table or not is subjected to font classification, and a proper font can be more accurately selected for rendering, so that the accuracy of document display is improved.
In one or more optional embodiments of the present invention, in a case where the second association table does not include the initial font name, the matching between the initial character code and each second font name in the second association table is performed to determine a target font name, and the specific implementation process may be as follows:
judging whether the initial character code is a designated character code or not under the condition that the second association table does not contain the initial font name;
and if not, matching the initial character code with each second font name in the second association table, and determining the target font name.
Specifically, a specified character code refers to a specified character code or codes, such as 0.
In practical application, if the initial font name is not contained in the second association table, whether the initial character code is the designated character code or not can be judged, if not, the actual font name of the characters in the description target document is the initial entity name, and correspondingly, the second font name corresponding to the initial character code can be searched from the second association table through the initial character code corresponding to the initial font name as the target font name.
Accordingly, after determining whether the initial character code is a specified character code, the method further includes: if yes, determining the default font name of the document display system as the target font name. In other words, when the initial font name is not included in the second association table and the initial character code is the designated character code, determining that the default font name of the document display system is the target font name, and then performing text rendering by using the font corresponding to the default font name.
In this way, by judging whether or not the initial character code is the specified character code, the character codes are classified, and in the case where the initial character code is not the specified character code, the specified character code is matched to the target font name for rendering, and in the case where the initial character code is the specified character code, the font name is directly defaulted as the target font name for rendering. The method not only can improve the efficiency of determining the target font name, but also can improve the matching degree of determining the target font name and the actual font name of the characters in the target document, thereby better preserving the format and style of the target document and improving the rendering effect and the aesthetic degree.
In one or more optional embodiments of the present invention, the matching the initial font name with each first character code in the first association table, after determining the initial character code, further includes:
and determining the initial font name as a target font name under the condition that the second association table contains the initial font name.
In practical application, on the basis of determining the initial character code, further, judging whether the second association table contains the initial character code, if so, indicating that the document display system is provided with the installation package of the corresponding font in the target document, directly determining the initial font name as the target font name, and rendering the characters by using the font corresponding to the target font name, thereby ensuring that the format and style of the rendered characters are consistent with those of the target document, improving the rendering effect, the readability and the aesthetic degree of the document, and improving the use experience of a user.
In one or more optional embodiments of the present invention, the matching the initial font name with each first character code in the first association table, and determining the initial character code may be implemented as follows:
Judging whether the initial font name exists in the first association table;
if yes, determining a first character code corresponding to the initial font name as an initial character code;
if not, determining the appointed character code as the initial character code.
In practical application, on the basis of acquiring the initial font names of the characters in the target document, searching is further performed in the first association table, if the initial font names are found, the first character codes corresponding to the initial font names in the first association table are determined to be initial character codes, and if the initial character codes cannot be found, the appointed character codes are determined to be the initial character codes. In this way, by judging whether the initial font name exists in the first association table, determining the initial character codes by adopting different methods, classifying the character codes is realized, under the condition that the initial font name exists in the first association table, the first character code corresponding to the initial font name is used as the initial character code, under the condition that the initial font name does not exist in the first association table, the appointed character code is determined as the initial character code, so that the efficiency of determining the target font name can be improved, the matching degree of determining the target font name and the actual font name of characters in the target document can be improved, the format and style of the target document can be better reserved, and the rendering effect and the attractiveness can be improved.
Illustratively, the family value of the font is searched in the table a (the first association table), and if the family value of the font is found, the code value corresponding to the family value of the font is used as the initial character code. If the family value of the font cannot be found, marking the code value corresponding to the family value of the font as 0 (appointed character coding).
It should be noted that, if the initial font name does not exist in the first association table, it is noted that the first font name acquired in the first association table is not abundant enough, and then the first association table may be updated according to the initial font name. I.e. after the initial font name does not exist in the first association table, i.e. if not, further comprising:
searching an actual character code corresponding to the initial font name;
and storing the initial font name and the actual character code association into the first association table to obtain the updated first association table.
Specifically, the actual character encoding entity refers to the character encoding for which the original font name is true.
In practical application, if the initial font name does not exist in the first association table, the initial font name is recorded, so that the first association table is convenient to update subsequently: and searching an actual character code of the initial font name, and adding the initial font name and the actual character code into a first association table to update the first association table. Therefore, the first association table is updated, a rendering foundation can be laid when the characters of the initial font name are rendered next time, and the character rendering capability of the document display system is improved.
Illustratively, when the family value of the font is not found in the table a (the first association table), the corresponding family value is recorded, then the code value corresponding to the family value is collected, and the family value and the code value are associated and added to the table a.
In one or more optional embodiments of the present invention, the matching the initial character code with each second font name in the second association table, before determining the target font name, further includes:
acquiring each second font name in the document display system;
determining second character codes corresponding to the second font names according to the first association table;
and storing the second font names and the corresponding second character coding associations into the second association table.
In practical application, on the basis of determining the first association table, all fonts in the document display system can be acquired, the second font names of all fonts are recognized, and then the second character codes corresponding to the second font names are searched from the first association table: for each second font name, if the second font name exists in the first association table, the first character code of the second font name in the second font name is used as the second character code of the second font name, and if the second font name does not exist in the first association table, the designated character code is determined as the second character code of the second font name. Further, each second font name and its corresponding second character encoding association are stored in a second association table. Therefore, the integrity and the reliability of the second association table can be ensured, and the efficiency and the accuracy of text rendering are further improved.
When the program or the document display system is started, all fonts in the document display system are acquired, the family value corresponding to each font is obtained, the codeage value corresponding to the font is obtained from the table a according to the family value of the font, and the obtained family value and the codeage value corresponding to all fonts are stored in a table b (second association table) in the database.
It should be noted that, each time a second character code corresponding to a second font name is determined, the second font name and its corresponding second character code may be stored in the second association table, or after the second character codes corresponding to all the two font names are determined, each second font name and its corresponding second character code may be stored in the second association table. The present invention is not limited in any way.
The text rendering method provided by the present invention is further described below with reference to fig. 2, where fig. 2 is a second schematic flow chart of the text rendering method provided by the present invention, and specifically includes the following steps.
