Optionally, after step 11, the method comprises: generator data, and this metadata is used to indicate the font information of body face.

Optionally, step 11 comprises:

Obtain the metadata preset, this metadata is used to indicate the font information of body face;

According to the body face of this metadata determination e-book.

Fig. 2 is the process flow diagram of the another kind of e-book font method of adjustment according to an exemplary embodiment, and this e-book font method of adjustment can comprise following several step:

In step 21, determine the body face of e-book, this body face is text font used in e-book.

The word of an e-book has following a few class usually: text, quoted passage, explanatory notes, title, inscription etc.Fig. 3 shows the interface schematic diagram shown when associated electrical books enter reading model, example, and 801 in Fig. 3 is text, and 802 is title.It should be noted that, usually the catalogue of e-book is not analyzed in disclosure embodiment.

Under general situation, except text, other ratios shared by a few class word are less, except text, other a few class words occur that the probability that multi-font is arranged in pairs or groups is larger simultaneously, also namely the text of an e-book uses a kind of font usually, and user's most of time is all reading the larger body part of word amount.Font, also known as the style of calligraphy, refers to the style style of word, as the regular script of Chinese character hand-written, running hand, rapid style of writing.

The font that body part in e-book uses is called the body face of e-book by disclosure embodiment, and therefore, how the body face of self-defined e-book is key problem.First the body face of self-defined e-book needs the body face determining e-book, determines that the body face of e-book can comprise following two aspects:

On the one hand, the body face of e-book can be determined by a kind of algorithm, as according to the frequency of utilization of font each in e-book, the body face of this e-book can be determined.

It should be noted that, the chapter construction of an e-book can carry out according to the catalogue of e-book, ignore the level of e-book by e-book leveling, content between every two catalogues is the content of chapters and sections, associated electrical books are as ePub e-book, the separation of chapters and sections is would have been completed when making, and (English: The Extensible Hyper Text MarkupLanguage by extensible HyperText Markup Language; Be called for short: mode XHTML) defines each chapters and sections.XHTML is a kind of markup language, manifestation mode and HyperText Markup Language (English: Hyper Text Mark-up Language; Be called for short: HTML) similar, but grammatically stricter.From inheritance, HTML is a kind of application based on standard general markup language, is one markup language very flexibly, and XHTML is then based on extend markup language, and extend markup language is a subset of standard general markup language." hypertext " just refers in the page can comprise picture, link, even the non-legible element such as music, program.The structure of XHTML document comprise " head " partly (English: Head) and " main body " partly (English: Body), wherein " head " portion provides the information about webpage, " main body " part provides the particular content of webpage.Known see correlation technique, these two marker characters of <head> and </head> represent beginning and the ending of header information respectively.The mark comprised in head is title, the content such as preamble and explanation of the page, and itself does not show as content.These two marker characters of <body> and </body> represent beginning and the ending of actual content respectively, namely for defining the main body of document.In addition, actual content in XHTML document can be divided into several paragraphs by and marker character, and each paragraph can be divided into several fragments by and marker character.Example, an XHTML document format is as follows:

It should be noted that, no matter be with the e-book of XHTML document compiling, or with other documents as JSON (JavaScript Object Notation, javaScript object representation, a kind of lightweight data store and Interchange Format) e-book that makes, disclosure embodiment all can set up the logical model of this e-book, example, the logical model of an e-book can comprise at least one chapters and sections, each chapters and sections can comprise at least one paragraph again, and each paragraph can comprise at least one fragment according to the difference of parameter preset.Example, parameter preset can be font, the parameter such as color and font size of word, then can be divided into several fragments according to the font of the word of this paragraph content, or can be divided into several fragments according to the color of the word of this paragraph content.Disclosure embodiment, according to above-mentioned division, provides a kind of logical model of e-book, and this logical model as shown in Figure 4,1 e-book can comprise n chapters and sections, and 1 chapters and sections can comprise n paragraph, and 1 paragraph can comprise n fragment, wherein, n is more than or equal to 1.Above-mentioned parameter preset can be font, color and font size.For the e-book of XHTML document compiling, the logical model of an e-book comprises multiple XHTML document, the corresponding chapters and sections of each XHTML document, each chapters and sections are divided into multiple paragraph according to the block level label (i.e. and marker character) in XHTML document, each paragraph is divided into multiple fragment according to the row interior label (i.e. and marker character) in XHTML document, logical model shown in design of graphics 4.If not row interior label in block level label, then content wherein forms a fragment.

Accordingly, in the process of body face determining e-book, the logical model of the e-book that can provide according to disclosure embodiment is searched, determine that first the body face of e-book can determine the font that in the body face of all fragments in any one, frequency of utilization is the highest, then determine the font that in the body face of all paragraphs in arbitrary chapters and sections, frequency of utilization is the highest, then the font the highest according to frequency of utilization in the body face of all chapters and sections determines the body face of this e-book.

Optionally, according to the frequency of utilization of font each in e-book, determine the body face of e-book, as shown in Figure 5, can comprise:

In step 211, using the body face of font the highest for frequency of utilization in each chapters and sections as each chapters and sections.

Example, font as the highest in frequency of utilization in a certain chapters and sections is regular script, then using the body face of regular script as these chapters and sections.

The e-book font method of adjustment that disclosure embodiment provides can be determined paragraph, determine fragment according to row interior label ( and the marker character as in XHTML) according to the block level label ( and the marker character as in XHTML) in the expression document of e-book.

Optionally, each chapters and sections can comprise at least one paragraph, then step 211 is as shown in Figure 6, comprising:

In step 2111, using the body face of font the highest for frequency of utilization in paragraph each in arbitrary chapters and sections as each paragraph.

Example, have five paragraphs in a certain chapters and sections, the font that five paragraph frequencies of utilization are the highest is respectively regular script, the Song typeface, black matrix, regular script and Microsoft refined black, then the body face of five paragraphs in these chapters and sections is respectively regular script, the Song typeface, black matrix, regular script and Microsoft refined black.

Further again, if each paragraph needs to add unique pattern to some content, also need the mark adding display, as XHTML can mark a fragment with row interior label.Because each paragraph can comprise at least one fragment, then step 2111 is as shown in Figure 7, comprising:

In step 2111a, using the body face of font the highest for frequency of utilization in fragment each in any one as each fragment.

As mentioned above, each paragraph includes at least one fragment according to the difference of parameter preset, when supposing that parameter preset is the color of word, then current paragraph is divided into three fragments according to text color, the text color of the first fragment is red, the text color of the second fragment is blue, the text color of the 3rd fragment is black, and the font that in the first fragment, frequency of utilization is the highest is black matrix, the font that in second fragment, frequency of utilization is the highest is regular script, the font that in 3rd fragment, frequency of utilization is the highest is the Song typeface, then the body face of the first fragment is black matrix, the body face of the second fragment is regular script, the body face of the 3rd fragment is the Song typeface.

In step 2111b, determine the font that in the body face of all fragments in any one, frequency of utilization is the highest.

In step 2111c, if the font that in the body face of all fragments, frequency of utilization is the highest is a kind of, then determine that the font that in the body face of all fragments, frequency of utilization is the highest is the body face of any one.

In step 2111d, if the font that in the body face of all fragments, frequency of utilization is the highest is at least two kinds, then the font that font the highest for frequency of utilization in the body face of all fragments uses at first in any one is defined as the body face of any one.

In step 2112, determine the font that in the body face of all paragraphs in arbitrary chapters and sections, frequency of utilization is the highest.

In step 2113, if the font that in the body face of all paragraphs, frequency of utilization is the highest is a kind of, then determine that font that in the body face of all paragraphs, frequency of utilization is the highest is the body face of arbitrary chapters and sections.

In step 2114, if the font that in the body face of all paragraphs, frequency of utilization is the highest is at least two kinds, then the body face of first paragraph at arbitrary chapters and sections is defined as the body face of arbitrary chapters and sections.

In the mobile Internet epoch, e-book needs to present on the display screen of intelligent terminal, and whether the font word outward appearance presented on a display screen can be accepted to be determine that can it be used as the key factor of body face by user for a long time.Handwritten form as more inclined in regular script, is all seldom used as body face in paper book is published; Small tenon Song stroke is excessively thick, is generally used as title, is seldom used as body face; Imitation Song-Dynasty-style typeface stroke is meticulous, and on the display screen that sharpness is not high, pixel sense is comparatively obvious.Therefore, in order to improve the accuracy that body face is determined, the body face that can be e-book arranges one and comprises multiple reference font scope with reference to font, and the multiple reference fonts comprised are the usual font of text in e-book, as the Song typeface often used in paper publication, computer or can the black matrix that often uses of the operating system of terminal, on high cls, effect waits line body etc. preferably.Like this, step 211 as shown in Figure 8, comprising:

In step 21101, obtain the reference font scope preset, comprise multiple with reference to font with reference to font scope, this reference font is the usual font of text in e-book.

Example, with reference to font scope can comprise the Song typeface, black matrix and etc. line body.

In step 21102, add up in each chapters and sections the frequency of utilization of font in each chapters and sections belonged to reference to font scope.

In step 21103, will belong in each chapters and sections with reference to font scope and the highest font of frequency of utilization as the body face of each chapters and sections.

In the step 212, the font that in the body face of all chapters and sections, frequency of utilization is the highest is determined.

In step 213, if the font that in the body face of all chapters and sections, frequency of utilization is the highest is a kind of, then determine that the font that in the body face of all chapters and sections, frequency of utilization is the highest is the body face of e-book.

In step 214, if the font that in the body face of all chapters and sections, frequency of utilization is the highest is at least two kinds, then determine that the body face of middle chapters and sections is the body face of e-book, these middle chapters and sections are the chapters and sections of predeterminated position in the chapters and sections in all chapters and sections except first chapters and sections and end chapters and sections.

On the other hand, the producer of e-book can when making in e-book, arrange the metadata of body face to this e-book, this metadata is used to indicate the font information of this body face, and subscriber equipment obtains the information of body face by the metadata set.Metadata, also known as broker data, relay data, the data about data, the mainly information of data of description attribute, be used for supporting that correlation technique cannot determine the body part in e-book as function such as instruction memory location, historical data, resource lookup, file record etc., thus also cannot the font that uses of body part, there is not the concept of body face, more there is not the metadata of the font information being used to indicate body face.

Optionally, as shown in Figure 9, step 21 comprises:

In step 21a, obtain the metadata preset, this metadata is used to indicate the font information of body face.

In step 21b, according to the body face of metadata determination e-book.

The font used due to e-book text is determined by the producer of e-book, therefore, arranges body face not only efficient but also accurate by producer.

In step 22, generator data, this metadata is used to indicate the font information of body face.

After determining the body face of e-book in real time according to the algorithm of step 21, the target font that can will the text importing of body face be used in e-book to indicate for user, but in order to reduce costs, make the body face in self-defined e-book next time more convenient, also the body face of the e-book after determining can be write back in this e-book in the mode of metadata and go.

In step 23, obtain the target font of user's instruction.

User can specify self-defining font according to personal like and reading environment etc., i.e. target font.Example, the target font that user specifies can be refined black etc. for the Song typeface, regular script, black matrix and Microsoft.

In step 24, will in e-book, use the text importing of body face for target font, and keep the font of the word in e-book except using the word of body face constant.

According to step 21, after determining the body face of e-book, by the target font using the text importing of body face to indicate for user in e-book, namely user can customize the body face of e-book, reach the object of font personalization, and keep the font of the word in e-book except using the word of body face constant.As employed the e-book of the Song typeface as body face (text use font) for one, when can carry out real-time typesetting to e-book, the font of the Song typeface is replaced with target font---the black matrix of user's instruction, at e-book in the current same drafting using black matrix to carry out word, meanwhile, explanatory notes, annotation and title etc. all keep raw font constant.It should be noted that, typesetting, refer to and the visual information elements such as word, picture, figure are adjusted position, size in layout, make the process of layout's methodization of e-book.

Example, e-book has three chapters and sections, and the target font of user's instruction is for waiting line body, and the situation of the fragment that the paragraph that each chapters and sections of e-book comprise, each paragraph comprise and the font that each fragment uses is as shown in table 1:

Table 1

As shown in Table 1, the font that the first paragraph frequency of utilization of the first chapters and sections of this e-book is the highest is black matrix, then the body face of the first paragraph of the first chapters and sections is black matrix; The font that second paragraph frequency of utilization of the first chapters and sections is the highest is the Song typeface, then the body face of the second paragraph of second chapter is the Song typeface.The font the highest due to frequency of utilization in the body face of two paragraphs of the first chapters and sections is two kinds, then the body face of the first chapters and sections is body face---the black matrix of the first paragraph.

The font that first paragraph frequency of utilization of the second chapter of this e-book is the highest is the Song typeface, then the body face of the first paragraph of second chapter is the Song typeface; The font the highest due to three fragment frequencies of utilization of the second paragraph of second chapter is the Song typeface, black matrix and regular script, then the Song typeface used at first is defined as the body face of the second paragraph of second chapter, then the body face of second chapter is the Song typeface.

Chapter 3, the font that the first paragraph frequency of utilization of joint is the highest is regular script, then the body face of the first paragraph of chapter 3 joint is regular script; Chapter 3, the font that the second paragraph frequency of utilization of joint is the highest is the Song typeface, then the body face of the second paragraph of chapter 3 joint is the Song typeface; Chapter 3, the font that the 3rd paragraph frequency of utilization of joint is the highest is black matrix, then the body face of the 3rd paragraph of chapter 3 joint is black matrix.The font the highest due to frequency of utilization in the body face of three paragraphs of chapter 3 joint is three kinds, then the body face of chapter 3 joint is body face---the regular script of the first paragraph.

Body face due to the first chapters and sections is black matrix, the body face of second chapter is the Song typeface, chapter 3, the body face of joint is regular script, and the font that in the body face of three chapters and sections, frequency of utilization is the highest is three kinds, then the body face of this e-book is body face---the Song typeface of middle chapters and sections and second chapter.

In order to improve the accuracy that body face is determined, the reference font scope that the body face being assumed to be this e-book is arranged is black matrix and the Song typeface, then this above-mentionedly determines that, in the process of the body face of e-book, the body face of the first chapters and sections is constant, or is black matrix; The font the highest due to the 3rd fragment frequency of utilization of the second paragraph of second chapter is regular script, regular script does not belong to reference within the scope of font, therefore, the font that the frequency of utilization of the second paragraph of second chapter is the highest is the Song typeface and black matrix, and the body face of second chapter is the Song typeface; Because the font regular script that the first paragraph frequency of utilization of chapter 3 joint is the highest does not belong to reference within the scope of font, second paragraph and the highest font of the 3rd paragraph frequency of utilization belong to reference within the scope of font, therefore, can can determine according to the body face of the second paragraph of chapter 3 and the 3rd paragraph according to the body face of chapter 3, from the above, the body face of chapter 3 is the Song typeface.Therefore, the body face of this e-book is body face---the Song typeface of middle chapters and sections and second chapter.The reference font scope proposed can reduce the number of times of font frequency of utilization in each chapters and sections of adding up each chapters and sections further.

Finally, will in e-book, use the text importing of the Song typeface for waiting line body, and keep the font of the word in e-book except using the word of the Song typeface constant.

As one of most popular e-book, ePub is a kind of e-book form based on XML, and it is (English: Cascading Style Sheet by the Cascading Style Sheet of W3C that it goes out plate structure; Be called for short: CSS) and XHTML specification describe, the bookbinding structure going out plate structure is by its open packaging form (English: OpenPackaging Format; Be called for short: OPF) specification describes, the packaging structure of physical file is (English: Open Container Format by its open container form; Be called for short: OCF) specification describes.Wherein, CSS really can accomplish that webpage shows a kind of form design language be separated with content.For the performance of conventional HTML, CSS can carry out the accurate control of Pixel-level to the position typesetting of the object in webpage, support nearly all font size pattern, have the ability to web object and model pattern editor, and can preliminary interaction design be carried out.

Disclosure embodiment, for a certain e-book of ePub form, is described in detail to this e-book font method of adjustment.Suppose that current time user reads this e-book by subscriber equipment (as mobile phone), Figure 10 show this ePub e-book carry out font adjustment before schematic diagram.With reference to font scope comprise the Song typeface, black matrix and etc. line body three kinds, Figure 11 is the process flow diagram of another the e-book font method of adjustment according to an exemplary embodiment, and this e-book font method of adjustment can comprise following several step:

In step 301, according to ePub format specification, it is carried out to the parsing of bookbinding structure, obtain the XHTML text of each chapters and sections of ePub e-book.

In step 302, obtain the reference font scope preset, all chapters and sections of chaining search ePub e-book, determine the body face of each chapters and sections.

Optionally, step 302 as shown in figure 12, comprising:

In step 3021, adopt the XML parser of standard to carry out parsing to the XHTML text of current chapters and sections and form tag tree.

In step 3022, the traversal of carrying out depth-first to the tag tree generated builds the logical model of current chapters and sections.

First the CSS pattern completing current label in ergodic process is searched, and uses information with the font obtaining current label; Secondly according to the principle construction logical model that block level label (as and marker character) forms paragraph, row interior label (as and marker character) forms fragment.If without any label in block level label, then content wherein forms a fragment.

In step 3023, circulate all paragraphs of current chapters and sections, determines the body face of each paragraph.

Optionally, step 3023 as shown in figure 13, comprising:

In step 3023a, all fragments of the current paragraph that circulates, determine the font that each fragment uses, if it is with reference within the scope of font, then retains, otherwise skip.

In step 3023b, if the font that in the body face of all fragments, frequency of utilization is the highest is a kind of, then determine that font that in the body face of all fragments, frequency of utilization is the highest is the body face of current paragraph; Otherwise, the font that font the highest for frequency of utilization in the body face of all fragments uses at first in current paragraph is defined as the body face of current paragraph.

In step 3024, if the font that in the body face of all paragraphs, frequency of utilization is the highest is a kind of, then determine that font that in the body face of all paragraphs, frequency of utilization is the highest is the body face of current chapters and sections; Otherwise, the body face of first paragraph at current chapters and sections is defined as the body face of current chapters and sections.

In step 303, if the font that in the body face of all chapters and sections, frequency of utilization is the highest is a kind of, then determine that font that in the body face of all chapters and sections, frequency of utilization is the highest is the body face of current ePub e-book; Otherwise, be the body face of current ePub e-book by the body face of middle chapters and sections.

It should be noted that, the body part of middle chapters and sections normally ePub e-book.

The body face of ePub e-book can be determined according to above-mentioned steps.

In step 304, generator data, this metadata is used to indicate the font information of body face.

In step 305, the target font of user's instruction is obtained.

Within step 306, will in current ePub e-book, use the text importing of body face for target font, and keep the font of the word in current ePub e-book except using the word of body face constant.

Correlation technique cannot determine the body part in e-book, thus also cannot the font that uses of body part, there is not the concept of body face, more there are not the data of the font information being used to indicate body face, therefore, cannot realize in correlation technique adopting searching and replacement of the word of body face display, and in disclosure embodiment, can by determining body face, then adopt the original word adopting body face display of target font display, realize adopting searching and replacement of the word of body face display.Example, suppose to use body face for black matrix in current ePub e-book, the target font that user specifies is regular script, so the schematic diagram after font adjustment is carried out as shown in figure 14 to current ePub e-book, in Figure 14 and Figure 10 140 represents the word using body face in current ePub e-book, the font of 140 before adjustment is black matrix, and the font of 140 after adjustment is regular script.Can find out; this e-book font method of adjustment makes user when read electronic books; both most of text importing user read is in order to the black matrix of user habit; namely the demand of user to the self-defined font of e-book is met; do not destroy again the collocation of original font; namely save the original font collocation of e-book to greatest extent, reach the balance between user's request and the creation protecting e-book producer.
