The process is the PDF file generation process. Optionally, when the PDF file is generated, a PDF Mongolian paragraph corresponding to the target Mongolian paragraph is correspondingly configured, wherein the PDF Mongolian paragraph is configured with a key value pair character string. When the computer device processes the PDF Mongolian paragraph, the character string is selected for some or all of the key values at the same time.
In summary, in the process of generating a PDF file including a Mongolian, content analysis is performed based on contents in a Mongolian font index library under the condition of obtaining Mongolian information, so as to generate a key value pair character string corresponding to a Mongolian paragraph, the corresponding key value pair character string is reserved in the process of generating the PDF file, and in the subsequent text copying process, text copying can be performed on the character string corresponding to the key value, so that correct identification and copy of the content of the Mongolian document are realized.
Fig. 2 is a schematic flow chart of another method for outputting a PDF file capable of copying a Mongolian according to an exemplary embodiment of the present application, and the method is applied to a computer device for explanation, and includes:
step 201, determining a location of a target Mongolian paragraph within the editable text.
Steps 201 to 203 are the determination process of the mongolian coordinate information. In this embodiment of the present application, a determination needs to be made on a position of a target Mongolian paragraph in an editable text, where the determining process may be to determine the number of pages of the target Mongolian paragraph in the editable text, and determine a distance between the target Mongolian paragraph and an upper frame, a distance between the target Mongolian paragraph and a lower frame, a distance between the target Mongolian paragraph and a left frame, and a distance between the target Mongolian paragraph and a right frame of a current page, so as to determine the position of the target Mongolian paragraph in the editable text.
Step 202, determining the text width of the target Mongolian paragraph.
The process is a process of determining the text width of the target Mongolian paragraph, and optionally, in some embodiments, the computer device may further obtain the text length of the target Mongolian to determine the text content of the target Mongolian paragraph.
Step 203, based on the text width and the position, generating Mongolian coordinate information corresponding to the target Mongolian paragraph.
The process is a process for determining Mongolian coordinate information. Alternatively, the Mongolian coordinate information may be implemented as a coordinate combination, where the coordinate combination includes the number of pages where the target Mongolian paragraph is located, the upper edge position of the target Mongolian paragraph, the left edge position of the target Mongolian paragraph, the length of the target Mongolian paragraph, and the width of the target Mongolian paragraph.
Step 204, generating a paragraph picture corresponding to the target Mongolian paragraph.
The process from step 204 to step 205 is a Mongolian corresponding to the target Mongolian paragraph, and in this embodiment of the present application, paragraph information of the target Mongolian paragraph is obtained based on image recognition.
Step 205, performing image recognition on the paragraph image to obtain Mongolian font information corresponding to the target Mongolian paragraph.
In the embodiment of the present application, the method for acquiring the Mongolian font information is not limited.
Step 206, obtaining Mongolian font information in the editable text.
In the embodiment of the application, the determination of the Mongolian font information is performed through an editing environment application program running on the editable text.
Step 207, determining a unit Mongolian glyph.
Steps 207 to 210 are the construction process of the Mongolian glyph index library. In the embodiment of the application, the Mongolian font index library can be adapted to different Mongolian fonts, and corresponding to the situation, as the Mongolian has at least two fonts, after the specific font of the Mongolian is determined by the computer equipment, the unit Mongolian font corresponding to the Mongolian font is determined.
It should be noted that, unlike the common chinese or english fonts, when two mongolian letters conforming to the writing rule are used in connection, there are three cases:
(1) The prior Mongolian letters and the subsequent Mongolian letters are unchanged;
(2) The prior Mongolian letters are unchanged, and the subsequent Mongolian letters are omitted;
(3) The preceding Mongolian letters and the following Mongolian letters form a new font. In this case, referring to fig. 3, a first mongolian letter 301 and a second mongolian letter 302 are combined to form a mongolian font 303.
Corresponding to the three situations, when determining the Mongolian font of the unit corresponding to the Mongolian font, the embodiment of the application determines the Mongolian font of the regular unit and the Mongolian font of the special-shaped unit, wherein the Mongolian font of the regular unit is used for uniquely corresponding Mongolian letters, the Mongolian font of the special-shaped unit is used for uniquely corresponding Mongolian letter combination, and the Mongolian combination comprises at least two Mongolian letters.
Step 208, generating a set of key strings based on the unit mongolian glyphs.
Optionally, the character string set includes at least one key character string.
In the embodiment of the application, the key character string is used for uniquely indicating the unit Mongolian font. Alternatively, the key string is represented by a four-bit 16-ary, in one example, one unit Mongolian glyph is defined as <033B >.
Step 209, determining a value string combination corresponding to the Mongolian letters.
The value string set includes at least one value string.
In the embodiment of the application, the value character string is used for indicating the character width corresponding to the unit Mongolian font and the text representation. Optionally, the value string corresponds to a graphic of a unit mongolian font and a text width corresponding to the graphic, and when the value string is received by the computer device, the corresponding mongolian can be represented on the display interface. In the embodiment of the application, the text representation can indicate the content of the Mongolian letters actually corresponding to the text representation.
At step 210, a character indexing rule is generated based on the set of key strings and the set of value strings.
In the embodiment of the application, the character index rule comprises an independent index rule, a hidden index rule and a combined index rule corresponding to the use condition of Mongolian;
the independent index rule adapts to the situation that the Mongolian character of the unit uniquely corresponds to the Mongolian letter;
the hidden index rule adaptation unit has the condition that Mongolian letters are omitted in Mongolian fonts;
the combined index rule adapts to the case where the unit mongolian glyph includes at least two mongolian letters.
Step 211, based on the character index rule, establishing a Mongolian font index base.
Wherein, for adapting the hidden index rule, the method further comprises: determining a first value string corresponding to the omitted Mongolian letters; determining a second key character string adjacent to the value character string and a second value character string corresponding to the second key character string; the first value string is merged into the second value string. That is, in an exemplary form, the value character corresponding to the key character <019B > is <1824180B >, in which case the text token corresponding to the value character <180B > is hidden due to the text token corresponding to the value character <1824> being used together, and thus, is divided into the previous value character strings to be combined.
Step 212, determining a key value pair character string corresponding to the target Mongolian paragraph based on the Mongolian font information, the Mongolian font information and the Mongolian coordinate information based on the character index rule corresponding to the Mongolian font index library.
The process is the generation process of the key value pair character string.
In step 213, a PDF file corresponding to the editable text is generated.
This process corresponds to the process shown in step 103, and will not be described here.
In step 214, the target text is determined based on the text selection signal.
Steps 214 through 215 are text selection and copying processes. In the embodiment of the application, due to the non-editability of the PDF file, optionally, the computer device receives the area selection signal; the target region is determined based on the region selection signal and the text selection signal is generated based on the target region.
And step 215, determining and acquiring a key value pair character string corresponding to the target text.
In summary, in the process of generating a PDF file including a Mongolian, content analysis is performed based on contents in a Mongolian font index library under the condition of obtaining Mongolian information, so as to generate a key value pair character string corresponding to a Mongolian paragraph, the corresponding key value pair character string is reserved in the process of generating the PDF file, and in the subsequent text copying process, text copying can be performed on the character string corresponding to the key value, so that correct identification and copy of the content of the Mongolian document are realized.
It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present invention, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the invention, and are also considered to be within the scope of the invention.
