embodiment 5:
Provide a specific embodiment of the present invention below, a kind of word modification method, comprises the steps:
(1) analyzing step: the Word message receiving document, as received a streaming word content, being ePub streaming document in the present embodiment, parsing font resource wherein and word content, see 205 steps in Fig. 2.
Described font resource is character font data, is a kind of data acquisition containing font pattern set, character code collection, it is described that the mapping relations of character code to font, and the descriptor of each font.Font describes the information such as width, height that what and it each calligraphy and painting become in simple terms.Font can exist with the form of unique file, also can be embedded in document the part becoming document.
The order that described word content is word, system for font distribute for identifying the font name of font or numbering, drawn for descriptive text time the font size of size and each word corresponding to unicode encoded radio.Also can think that word content is exactly the set of text description, a text description mainly comprises its code value (determining specifically which word by code value), it uses which font in addition.The data content received can be resolved to font resource and word content by analyzing step.In the present embodiment, process respectively for different character font datas, due to the corrected parameter that different fonts has different word wide and different, process respectively for different character font datas, the judged result to each font can be improved, and improve correction effect, thus greatly better typesetting effect.
(2) determining step: find out the embedded font containing wrong font descriptor.In this step, judge successively for often kind of font resource, judge the font containing wrong font descriptor, see 210 steps in Fig. 2.First judge whether current font to be analyzed is embedded font, wait if current to judge the embedded font of font right and wrong, then can think correct font, embedded font is then processed: the word sample choosing some in the word content analytically gone out, these word samples all belong to this font to be judged, and they are not punctuation marks, then these word samples are obtained respectively to word width values and the font frame rectangle width value of same font size, calculate the word width values of word in each sample and the ratio of font frame rectangle width value, and assembly average, then judge whether described mean value exceeds threshold value, if mean value exceeds threshold range (excessive or too small), then marking this font is embedded font containing wrong font descriptor.
In this step, by the mean value of the ratio of word width values in statistical sample and font frame rectangle width, compare with threshold range, thus the embedded font obtained containing wrong font descriptor, because non-embedded font gets final product normal typesetting without the need to process, for the correct embedded font of font descriptor also without the need to process, therefore the embedded font containing wrong font descriptor is obtained by said method, and process targetedly, decrease treatment capacity, improve processing speed, in addition, by the mode of sample statistics, the method is made to have general applicability, and implement simple and convenient.
(3) error correction step: for the word used containing wrong font descriptor font, first judge whether it is wide word, according to judged result, revising employing in determining step those words be judged to containing wrong font descriptor font respectively, seeing step 215 in Fig. 2.First for the word of the font used containing wrong font descriptor, judge whether this embedded font belongs to wide word (as Chinese, Japanese, Korean etc.), still belongs to other non-wide words according to its unicode encoded radio.For wide word, each font only needs calculating one secondary word wide, get the font frame rectangle width value mean value of some words sample, then use correction factor (empirical value rule of thumb determined) to revise mean value, the word namely calculating all wide words of this font is wide.Because each font only needs calculating one secondary word wide, in follow-up judgement, first, judge that the word of this word is wide whether as calculated, if do not calculate, choose the wide word sample using this font, then obtain the shaped edge width of frame value of sample and calculate average, then being revised with correction factor.If calculated, then the word of all wide words of this font calculated before directly calling is wide.For non-wide word, need, for each character cell calculating word is wide, first to obtain the font frame rectangle width value of character, revising with correction factor (empirical value).After revising, width value is multiplied by font size to obtain actual word wide, and described actual word is wide is correct word width values.
In this error correction step, first for the word used containing wrong font descriptor font, first judge whether it is wide word, sample average is calculated for wide word and revises, non-wide word is obtained the font frame rectangle width value of character and revised.For wide and non-wide word, take different correction strategies, because wide word is as Chinese, Korean, itself is wide, after therefore once calculating, follow-uply can directly to call; For non-wide word, waiting and need to process for each character separately, like this, by revising targetedly, improve the accuracy that it calculates.Due in makeover process, be take relative value as the correction that standard is carried out, after therefore revising, needing to be multiplied by font size, to obtain actual word wide.
(4) composition step: all words are carried out typesetting.Typesetting is placed into by the word in word flow in applicable one layout region of showing medium size one by one, undertaken arranging and line-break by streaming word, according to revised word wide information, word is arranged one by one, thus determine that each word is showing the concrete coordinate on medium, sees step 220 in Fig. 2.First, each word in word flow is processed successively; By error correction step, correct word width values is obtained for the embedded font containing wrong font descriptor, for embedded font and non-embedded font not containing wrong font descriptor, directly obtains word width values; Then be added to current line arrange text width by wide for current word, compare with this width and one layout region width, if be greater than one layout region width, then reset current line and arrange text width and the line height that added up by row baseline, then this word under current end of line row, the maximal value of the high word height in previous row arrangement of row; If be not more than one layout region width, direct under current end of line row this word.Particular flow sheet is see Fig. 5.In this step, for the embedded font containing wrong font descriptor, word width values is obtained by error correction step, the current text width of typesetting is added to by wide for current word, then this width is compared with one layout region width, be not more than, directly insert, otherwise line feed is inserted, this ensures that there word sequentially to insert in turn, ensure that typesetting effect.
Word modification method described in the present embodiment, comprise analyzing step, determining step, error correction step and composition step, first literal resource and word content is parsed, then the embedded font containing wrong font descriptor is found out according to judgment criteria, then wide judgement is carried out for this embedded font, widely for whether to revise respectively, wide word and non-wide word difference are come and revises, uneven in order to solve the line space that may occur in process of typeset, the problems such as word excesssive gap or text overlays, effectively improve readability and the aesthetic property of content.
embodiment 6:
In the present invention, the emphasis of the present embodiment relies on for needing in process of typeset the process that font descriptor calculates typesetting position, and the typesetting rule of the more refinement related in concrete enforcement is mentioned in the present embodiment.In conjunction with a concrete application example in the present embodiment, be described.
Provide an ePub document in the present embodiment, the effect after typesetting as shown in Figure 7.It contains 3 kinds of fonts, is the font 1 of title respectively, the Chinese font 2 in text and the english font 3 in text, and wherein font 1 is correct font, and font 2 and font 3 are the fonts containing the wide information of erroneous words.
Adopt the text composing system with error correction in the present embodiment, see Fig. 3, use the word modification method of its correspondence, process flow diagram is see Fig. 2.First 3 kinds of font resources and the word flow (step 205) of document use is parsed; Then the 3 kinds of fonts parsed are judged (step 210) respectively, judge that font 2 and font 3 are wrong fonts; Then wide word (Chinese and Chinese punctuation mark) the word width values (step 215) in font 2 is calculated; Finally by typesetting unit, word flow is carried out typesetting (step 220).
Detailed process is as follows:
(1) receive document to be analyzed, as shown in Figure 7, parse font resource wherein and word content.It contains 3 kinds of fonts, is the font 1 of title respectively, the Chinese font 2 in text and the english font 3 in text, and wherein font 1 is correct font, and font 2 and font 3 are the fonts containing the wide information of erroneous words.
(2) deterministic process is with reference to Fig. 4, assesses (step 305) successively, judge whether font is embedded font (step 310) to 3 kinds of fonts, due to the embedded font of font 1 right and wrong, marks it for correct font (step 335).
Font 2 and font 3 are all embedded fonts, setting sample number is 5,5 word samples (step 315) are chosen from respective word content, the word sample chosen for font 2 is " ice ", "AND", " fire ", " it ", " song ", and the word sample chosen for font 3 is " e ", " p ", " i ", " c ", " f ".Word width values when obtaining these word sample font sizes 1 respectively and font frame rectangle width value, concrete numerical value as shown in Table 1 and Table 2.Can be calculated the word width values of font 2 and font 3 and shaped edge width of frame value ratio average be respectively 0.57 and 0.66(step 320).Font 2 belongs to Chinese font, and rule of thumb preset threshold range is 0.9-1.1, and font 3 belongs to english font, and rule of thumb preset threshold range is 1.2-1.4.Font 2 and the ratio average of font 3 and the threshold range corresponding to it are contrasted (step 325), they, all beyond threshold range, are labeled as the font (step 330) containing wrong font descriptor by two fonts.
