Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiment one
At first, before the narration embodiment of the invention, simply introduce first this paper related some concepts and term:
Windows system: the window platform software systems that refer to Microsoft.
IOS: refer to the plateform system of Apple, comprise Mac, iPad, iPhone etc.
Android: refer to what Google company released, current a lot of business mens are supported the plateform system of mobile device, such as Samsung, association etc.
EPUB: be the very important concept of this paper.EPUB is the format description file of an e-book, comprises the information such as encode Chinese characters for computer, book version form of this e-book.Specifically, the EPUB file is open file standard, the EPUB file is mainly described the space of a whole page composing control information of book version, the coding standard of use Chinese character, Hanzi internal code, font, size, position etc., explanation for EPUB, obtain exactly coding standard and ISN, and correspond to according to coding standard in the order of GB18030, sort.
Mobi: be the e-book format description file that uses after Amazon kindle releases, principle is same as the EPUB form.
The spine chained list: the part relevant with encode Chinese characters for computer in the EPUB file, this table is the chained record structure, order comprises EPUB and comprises all chapters and sections index informations, and coding standard and Hanzi internal code information.
The UTF-8 coding method: identify literal take 8 as unit, the coding method of variable byte decides maximum 4 bytes according to the UNICODE coding of this symbol.The character of different range is used the coding of different length.For the character between the 0x00-0x7F, the UTF-8 coding is identical with the ASCII coding.
The standard word library format character library of TrueType character library: Windows and iOS system, system has finished for the reduction of character library and explanation, is called for short TTF file (character library).
The OpenType character library: the standard word library format of compatible Adobe postscript Type1 and TrueType form, be called for short OTF file (character library).
Postscript Type1: be the character library standard of Adobe definition, and the page-description language Postscript of Adobe is fully compatible.
GB2312-80: the encode Chinese characters for computer standard, contain 6763 Chinese characters.GB12345-90: the traditional font of corresponding GB2312-80 is expanded, and has 6866 Chinese characters.
GBK: the encode Chinese characters for computer standard, expand based on GB2312-80, have 20902 Chinese characters.
GB18030:GB18030-2000 encode Chinese characters for computer standard, 27533 Chinese characters are collected in the expansion on the GBK basis altogether, and current general-purpose system is all supported this standard code.GB18030-2005 has reached font about 75000 based on the expansion sets font of this standard.
Substantially about 3000 Chinese characters, the Chinese character that a general e-book is used also is at this quantitatively to the daily actual Chinese characters in common use that use.So the inventor finds in realizing process of the present invention, for e-book, the number of words of using only is about 40% of GB2312-80 generally in fact, about 10% of GB13080-2000, and for the e-book that has formed, the number of words of its use is determined more, has very large redundancy in the visible current e-book character library, and the present invention namely produces based on this principle.
Referring to Fig. 1, be the process flow diagram of the embodiment of the invention one method.The present embodiment discloses a kind of method of simplifying the e-book character library, and described method comprises:
S101: by the Hanzi internal code in the described format description file of format description file acquisition of resolving e-book, and press the ordering of prescribed coding order, form the code bit sequence list of described format description file.
In brief, this step namely resolves for the format description file of e-book, the Hanzi internal code that is occured to obtain the format description file, and by as the coded sequence of the appointments such as GB18030 sort, thereby form the code bit sequence list of this format description file.
Lower mask body is described in detail this step take this format description file layout of EPUB as example.And the disposal route of the forms such as Mobi and EPUB are basic identical, repeat no more.
Referring to shown in Figure 2, preferred, step S101 specifically can comprise:
S1011: by chained list registering section in the described EPUB file of described EPUB file acquisition of resolving described e-book;
S1012: travel through described chained list registering section, the paragraph content of each pagefile is turned to UNICODE conversion and ordering as UTF-8, form described code bit sequence list.
Specifically, at first need reading e-books EPUB file and resolve, comprise unpacking of compressed format, then read primary structure information, comprise complete composition information, and encode Chinese characters for computer information etc.
Then parse all Hanzi internal codes.Obtaining of encode Chinese characters for computer information is by parsing spine chained record structure, and obtains all relevant coded messages, and collects in the buffer memory.
The UNICODE coding result of layout ordering again.For UTF-8 coding carry out UNICODE conversion and ordering, obtain the in order coded message of discharging.
In the EPUB file, during the Chinese character information part of statistics, only need statistics chained list registering section in the EPUB file to get final product, i.e. spine chained list registering section.Spine is part relevant with encode Chinese characters for computer in the EPUB file, and this table is the chained record structure, and order comprises EPUB and comprises all chapters and sections index informations, and coding standard and Hanzi internal code information.The way that EPUB is resolved is, for resolving of UTF-8 coding, the paragraph content of each pagefile turned to the UNICODE conversion as UTF-8.At first according to spine structure traversal chained list, as long as less than the chained list end, just take out data, deposit buffer zone in binary mode, then these chapters and sections are carried out transcoding.
Transcoding for Hanzi internal code is the purpose that reads the EPUB data, and technical coding rule byte-by-byte according to UTF-8 is judged the first place value of letter, if less than 127, must cross DBC case for English or numeral, skips and disregards.If the first and 0xE0 be ﹠amp; Operation result is 0xC0, and inferior byte and 0xC0 do; It then is 2 byte UTF-8 Chinese characters that computing is not equal to 0x80, stores in order 2 bytes and gets final product.If the first and 0xF0 be ﹠amp; Operation result is 0xC0, and inferior byte reaches again byte and 0xC0 does; It then is 3 byte UTF-8 Chinese characters that computing is not equal to 0x80, stores in order 3 bytes and gets final product.Then utilizing win32 APIMultiByteToWideChar(system resource call function) front 2 parameters C P UTF8 can transfer the encoding list result of UNICODE to.
S102: according to the former font file of described code bit sequence list and described e-book, the mode by the Hanzi internal code that occurs in the described format description file of an index generates new font file.
In brief, the file of the Hanzi internal code GB18030 that this step namely obtains according to previous step, regenerate the code bit mapping table, the font index that exists out, do not have indexed font just need not leave in the character library, be packaged into the TTF(or the OpenType that simplify) character library, the character library that generates like this and EPUB file are fully corresponding.Be to generate the key of simplifying character library for the character code Map Sort of new word table, what be packaged into simplifies character library (TTF/OTF character library) and will finish unanimously with original character library, has just removed the data of irrelevant font.
Lower mask body is described in detail this step take the TTF font file as example.And OTF font file and TTF font file are basic identical.
Referring to shown in Figure 3, preferred, step S102 specifically can comprise:
S1021: obtain all data table items in the former font file, described all data table items comprise coding mapping table and other list items;
S1022: described code bit sequence list and described coding mapping table are compared, and the mode by the Hanzi internal code that occurs in the described format description file of an index generates new coding mapping table;
S1023: generate other new list items according to described new coding mapping table;
S1024: according to described new coding mapping table and described other new list items, synthetic new font file.
In brief, namely decompose the file structure of former TTF character library, then revise all data table items, be merged at last new TTF character library.The TTF(OTF that comprises the reading e-books appointment) table of all in font file data, then change into the new cmap table of simplifying according to UNICODE result and the cmap data that read, regenerate again the glyf table data of font description part, keep the font that needs, then according to cmap and glyf table, regenerate document alignment loca table, to modification and the generation of other correlation tables, finish at last the synthetic of each table, obtain e-book and specify TTF(OTF) simplify font file.Wherein relate to the encoding list according to the UNICODE after the EPUB parsing, compare with the coding mapping table (cmap table) of former character library and analyze, and the automatic coding mapping table of simplifying that generates, and according to new other list items of coding mapping table correction, such as offset table (loca table), font table (glyf table), and the modification of other correlation tables.
TrueType Font(TTF) file is comprised of some tables, analyzes the TTF table, and reconstruct TTF file is to generate the key of simplifying character library as required.The font description table is the general data item of statement TTF character contour, the TTF profile is to be made of quadratic B ezier splines, and profile is made of starting point, curve point and rectilinear point, and the front and back of point sequentially consist of the direction of profile, be outline counterclockwise, clockwise direction is interior profile.A Chinese character description is comprised of several profiles, and the data directory of this Chinese character is defined among the loca table.And the mapping of Hanzi internal code and loca table is finished by cmap table, and the outline data of all Chinese characters is described and is placed among the glyftable.After we read the e-book Hanzi internal code, the outline data of the Chinese character that occurs is retained among the glyf table, the Chinese character contour data that do not have to occur are no longer deposited, glyf table has just diminished like this, loca table and cmap table have also diminished simultaneously, all need to restructure according to new word table.The character library that regenerates like this is exactly the character library of simplifying for the certain electric philosophical works.
OTF simplifies the just the same of character library generating principle and TTF, and OTF character library and TTF character library are fully compatible, and Main Differences is that OTF is the character library form of compatible Adobe Postscript Type1.OTF also is comprised of profile, and the difference of TTF profile is that when explaining the OTF font file, processing mode is the same with TTF with three bezier curve and a straight line description.
S103: replace described former font file with described new font file, to finish simplifying of e-book character library.Referring to shown in Figure 4, preferred step S103 specifically can comprise:
S1031: the character library of revising in the described format description file selects to navigate to described new font file.
S1032: amended described format description file and described new font file are replaced original described format description file and described former font file, to finish simplifying of e-book character library.
In brief, the present embodiment method be input as EPUB file, TTF character library, be output as the EPUB file, simplify the TTF character library.And more than simplify the TTF/OTF character library, revise EPUB to replace the technical method of primary electron book, can be used as the high in the clouds service plan.
