Embodiment 5：
The specific embodiment of the present invention is given below, a kind of word modification method, comprises the following steps：
（1）Analyzing step：The text information of document is received, a streaming word content is such as received, is ePub in the present embodiment
Streaming document, font resource therein and word content are parsed, see 205 step in Fig. 2.
The font resource is character font data, be it is a kind of contain font pattern set, the data acquisition system of character code collection, it is described
Character code is to the mapping relations of font, and the description information of each font.Font describes each calligraphy and painting into assorted in simple terms
The information such as sample and its width, height.Font can exist in the form of unique file, can also be embedded into document into
For a part for document.
The font name or volume that are used to identify font that the word content is the order of word, system is font distribution
Number, the font size of size when being drawn for descriptive text and the unicode encoded radios corresponding to each word.
It is also assumed that word content is exactly the set of word description, a word description mainly includes its code value（It is true by code value
Surely it is specifically which word）, also have which font it has used.The data content received can be resolved to by analyzing step
Font resource and word content.In the present embodiment, it is respectively processed for different character font datas, because different fonts has
The wide and different corrected parameter of different words, is handled respectively for different character font datas, can improve and each font is sentenced
Disconnected result, and correction effect is improved, so as to significantly more preferable typesetting effect.
（2）Judgment step：Find out the embedded font containing wrong font description information.In this step, for every kind of word
Body resource is judged successively, is judged the font containing wrong font description information, is seen 210 step in Fig. 2.First determine whether to work as
Whether preceding font to be analyzed is embedded font, if current font to be judged is non-embedded font, is regarded as correct font；
Then handled for embedded font：A number of word sample is chosen in the word content analytically gone out, these word samples
Originally the font to be judged is belonged to, and they are not punctuation marks, then obtain same font size respectively to these word samples
Word width values and font frame rectangle width value, calculate the word width values of word in each sample and font frame rectangle width value
Ratio, then and assembly average judges whether the average value exceeds threshold value, if average value exceeds threshold range（It is excessive
It is or too small）, then it is the embedded font containing wrong font description information to mark this font.
In this step, by word width values in statistical sample and the average value of the ratio of font frame rectangle width, with threshold value
Scope is compared, and so as to obtain the embedded font containing wrong font description information, is because non-embedded font need not be handled
Can normal typesetting, for font description information correctly embed font contained without processing, therefore by the above method
The embedded font of mistake font description information, and targetedly handle, reduce treating capacity, improve processing speed, in addition,
By way of sample statistics so that this method has universal applicability, and implements simple and convenient.
（3）Error correction step：For using containing wrong font description information font word, first determine whether its whether be
Wide word, according to judged result, that containing wrong font description information font is judged in judgment step to having used respectively
A little words are modified, and see step 215 in Fig. 2.Firstly for the word using the font containing wrong font description information, root
Judge whether the embedded font belongs to wide word according to its unicode encoded radio（Such as Chinese, Japanese, Korean）, still fall within
Other non-wide words.For wide word, each font only needs one secondary word of calculating wide, takes certain amount word sample
Font frame rectangle width value average value, then use correction factor（Empirically determined empirical value）Average value is modified,
The word for calculating all wide words of this font is wide.Because each font only needs one secondary word of calculating wide, in follow-up judgement,
Whether it has been computed first, it is determined that the word of the word is wide, the wide word sample using the font has been chosen if not calculating, then
Obtain the font border width value of sample and calculate average, then corrected with correction factor.If be computed, directly
Connect and call the word of all wide words of this font calculated before wide.For non-wide word, it is necessary to be each character cell
Calculate that word is wide, the font frame rectangle width value of character is first obtained, with correction factor（Empirical value）It is modified.It is wide after amendment
Angle value is multiplied by font size wide, a width of correctly word width values of the actual word that obtain actual word.
In this error correction step, firstly for using the word containing wrong font description information font, it is first determined whether
Whether it is wide word, calculates sample average for wide word and be modified, the word of character is obtained for non-wide word
Shape frame rectangle width value is simultaneously modified.For wide and non-wide word, different correction strategies is taken, due to wide text
Word such as Chinese, Korean, itself is wide, therefore once can subsequently be directly invoked after calculating；For non-wide word, needs are waited
Handled individually for each character, so, by targetedly correcting, improve the accuracy of its calculating.Due to repairing
It is the amendment carried out using relative value as standard during just, therefore, it is necessary to be multiplied by font size, to obtain actual word wide after correcting.
（4）Composition step：All words are subjected to typesetting.Typesetting is that the word in word flow is placed into suitable exhibition one by one
In the one layout region for showing medium size, i.e., streaming word is arranged and line-break, according to the wide information of revised word by word
Arrange one by one, so that it is determined that specific coordinate of each word on displaying medium, is shown in step 220 in Fig. 2.First, handle successively
Each word in word flow；Obtained correctly by error correction step for the embedded font containing wrong font description information
Word width values, for the embedded font without wrong font description information and non-embedded font, directly obtain word width values；Then will
The current wide current line that is added to of word has arranged text width, with this width compared with one layout region width, if greater than typesetting
Peak width, then reset current line and arranged text width and row baseline is added up into a row highly, then under current end of line row
This word, the maximum of the high word height in previous row arrangement of row；Directly working as if one layout region width is not more than
Preceding this lower word of end of line row.Particular flow sheet is referring to Fig. 5.In this step, for the embedded word containing wrong font description information
Body, word width values are obtained by error correction step, are added to current typesetting text width by current word is wide, then by the width with
One layout region width compares, and no more than being then inserted directly into, otherwise line feed insertion, so ensures that word is sequentially sequentially inserted into,
It ensure that typesetting effect.
Word modification method described in the present embodiment, including analyzing step, judgment step, error correction step and typesetting step
Suddenly, literal resource and word content are parsed first, are then found out according to judgment criteria containing wrong font description information
Embedded font, then embed font for this and carry out wide judgement, for whether it is wide be modified respectively, by wide word and
Non- wide word is distinguished being modified, to the line space that solves to be likely to occur during typesetting is uneven, word gap
The problems such as excessive or text overlays, effectively increase the readability and aesthetic property of content.
Embodiment 6：
The emphasis of the present embodiment needs to rely on font description information calculating typesetting position during being directed to typesetting in the present invention
Process, the typesetting rule more refined being related in specific implementation do not refer in the present embodiment.Combined in the present embodiment
One specific application example, is illustrated.
An ePub document is provided in the present embodiment, the effect after typesetting is as shown in Figure 7.It contains 3 kinds of fonts, respectively
It is the font 1 of title, the english font 3 in Chinese font 2 and text in text, wherein font 1 are correct fonts, font 2
It is the font containing the wide information of erroneous words with font 3.
The text composing system with error correction is used in the present embodiment, referring to Fig. 3, uses its corresponding word amendment
Method, flow chart is referring to Fig. 2.3 kinds of font resources and the word flow that document uses are parsed first（Step 205）；Then it is right
The 3 kinds of fonts parsed are judged respectively（Step 210）, judge that font 2 and font 3 are wrong fonts；Then calculate
Wide word in font 2（Chinese and Chinese punctuation mark）Word width values（Step 215）；Finally by typesetting unit by word flow
Carry out typesetting（Step 220）.
Detailed process is as follows：
（1）Document to be analyzed is received, as shown in fig. 7, parsing font resource therein and word content.It is included
3 kinds of fonts, are the font 1 of title respectively, the english font 3 in Chinese font 2 and text in text, and wherein font 1 is
Correct font, font 2 and font 3 are the fonts containing the wide information of erroneous words.
（2）Deterministic process reference picture 4,3 kinds of fonts are assessed successively（Step 305）, judge whether font is embedded
Font（Step 310）, because font 1 is non-embedded font, it is correct font to mark it（Step 335）.
Font 2 and font 3 are all embedded fonts, set sample number as 5, and 5 words are chosen from respective word content
Sample（Step 315）, the word sample chosen for font 2 is " ice ", "AND", " fire ", " it ", " song ", is chosen for font 3
Word sample be " e ", " p ", " i ", " c ", " f ".Word width values and font frame when obtaining these word sample font sizes 1 respectively
Rectangle width value, concrete numerical value is as shown in Table 1 and Table 2.It can be calculated the word width values and font border width of font 2 and font 3
