More rich interactivity content is added, meets synchronously distribution papery and the electronic version such as books, magazine, once publishes, be multi-platform
The application demand propagated using, multipath.Introduction in detail below.
Referring to Fig. 1, the embodiment of the present application provide firstly a kind of method for showing electronic document, this method can include with
Lower step:
S101:Data for electronic documents bag is obtained, the packet includes layout's description information, interior of electronic document
Hold stream description information and resource description information, wherein, layout's description information includes the content flow object quoted
Page attribute information when information and document are shown, the content stream description information include the information of the resource object quoted with
And the display style information of resource object, the resource description information include the electronic document various number of resources required in display
According to set;
During specific implementation, data for electronic documents bag is that pre-production is good, can upload to network or by its other party
Formula is supplied to electronic document reader to be showed.Wherein, in the embodiment of the present application, can be by when making electronic document
Hierarchical description is carried out to electronic document from top to bottom according to resource, content stream, layout, upper strata object can be quoted in the de-scription
One or more directly lower floor's objects can repeatedly be quoted as data, lower floor's object by any directly upper strata description.
Wherein, resource description refers to the various resource data set in document, that is, document show needed for it is most basic
Data, the data such as word, picture, figure, predefined pattern, font packet, color table can be included but is not limited to.
Content stream description refers to the picture and text mixing paragraph collection that pattern description is presented, included according to the typesetting of content sequencing
Close, equivalent to one article, report etc., are the equal of according to certain pattern, order by the word in resource description, picture etc.
Content after layout.
Page layout description includes being used for the attribute information for showing the region of electronic document content in document file page, for example,
Whether the size of viewing area, resolution ratio, back gauge, background, full frame etc., the content for demonstrating the need for electronic document is shown
In specified region.In addition, in actual applications, viewing area in a page can also (can including more sub-regions
So that subregion to be referred to as to " page block ", the container for showing specific document content can be regarded as) so that can in a page
The features such as to embody similar newspaper subfield display, meanwhile, page layout description also includes the attribute information to these page blocks
Description, including the association between the pattern (for example, size, position, back gauge, frame, background etc.) of each page block, each page block
Relation (mainly tandem relation), content-data source and imposition layout's mode etc..In addition, in order to meet user to general
The reading requirement of logical fixed format, also for make it that not support that the document reader of the functions such as content stream parsing also can be to text
Shelves are shown, the positional information of row, word or word in each page block can be also preserved in page layout description, can when document is presented
Directly to use these contents to complete layout, realize that master former formula is presented.This is equivalent to have recorded according to certain content stream description
After carrying out typesetting, the positional information of row, word, word in page block, if follow-up only need to be shown according to this pattern, directly
Connect and shown according to the fix information recorded, it is not necessary to parse the information such as the pattern in content stream description again so that
The result shown every time is all identical.In addition, in page layout description, specific webpage region, page block, specific also may be selected
Particular sequence etc. in resource and content stream, and for its add link redirect, scaling rotation, animation, in the interactivity such as multimedia
Hold.
Content stream description is by reference using data such as the word in resource description, pictures;And again by space of a whole page cloth
Cited in office's description, to serve as the source that presentation content is wanted in page display area or its subregion (page block).Namely
Say, content stream description is formed by specific combination of resources, and the content of these content stream descriptions is eventually shown to the page
Viewing area or each page block in.It should be noted that in content stream description, can or section interior element interior for row
Show Styles (for example, color, font, font size etc.) is set, still, can't provide how many row be particularly shown, often row display
How many individual characters etc., these information can be described according to the layout selected when being particularly shown actually to determine.It is that is, false
It is the content for the content stream description for quoting the page block specifically when being shown if certain page block defined in certain page
It is added in the page block.Assuming that according to the font size of the content of the content stream description and the size of the page block, finally
The page block can accommodate down 10 rows, often 25 characters of row, then when the content of the content stream description is shown in the page block,
It will often go and show 25 characters, show 10 rows altogether.If it is appreciated that the page block refer to other content stream descriptions,
And the font size described in it is different, then the number of characters of often row display and the total line number that can show in the page block
Also can be different.In other words, for same content stream description, when cited in different layout's descriptions, at every page
The situation of middle display, required total page number etc. may all be different.
One page block or page block chaining combination can quote one or more content streams, specifically enter to electronic document
During row display, during imposition layout, carried out according to content stream sequencing;When one page block is booked, using being linked to
Next page block continue typesetting.
It should be noted that specifically when each layer content is described, the language such as XML can be used to describe space of a whole page cloth respectively
Office, content stream and resource etc., XHTML (eXtensible Hyper Text Markup can be used by being related to the description of form
Language, expansible hypertext markup language)+CSS (Cascading Style Sheets, CSS), coordinate certainly
Define label and describe adduction relationship and custom content, particular content can include:
Resource description:Digital ID can be used to identify each object, be related to the keys such as word in document, picture, figure
Content, also including the complementary data such as font packet, color table.Wherein, word allows to add parameter mode to quote sub- character by ID
String, big section word can rationally be split according to typesetting demand;Picture, font etc. save as unique file, and description file only records
Mark, path etc..
Content stream description:Digital ID can be used to identify each object, corresponding to independent article or segment, typically with text
Based on word, but picture, formula etc. in row can be also included, quote resource object as content, and can be paragraph and row interior element
Pattern is set;During specific implementation, embedded XHTML+CSS definition formats can be used, addition customized label is realized to resource pair
The reference of elephant or expanded function.In typesetting manufacturing process, content stream is typically that can require addition and modification according to page layout
's.
Layout describes:Layout can describe key parameter, front cover, catalogue corresponding relation, total page number, page order
Deng optional masterplate page, general page attribute etc..Layout's description can also sequentially describe all pages of attribute and interior one by one
Hold, page attribute may include a page size, resolution ratio, back gauge, background, whether full frame etc..Page content then includes one or more pages
Block container, at the same time it can also which page block's attribute is described respectively, for example, position, size etc., alternatively, can also include
Back gauge, frame, background etc.;Page block can one-way linkage to another page block, but permit there is ring;Linked sensing
Page block can quote one or more content streams as content.
It should be noted that in order to adapt to difference of the different mobile device terminals to resolution ratio, screen size and process performance
It is different so as to have preferable reading experience on different devices, layout's description can have more parts, that is to say, that an electricity
Subdocument can include Duo Tao layouts description and separate, it is allowed to for different terminal equipment selection using wherein a set of or
More sets, and select the content stream description and resource description quoted.
In addition, for same electronic document, in addition to layout's description can be more parts, content stream description
It can be more parts.That is, according to different layout's features, the specific resource description that content stream is quoted can also be
It is slightly different, for example, in layout's description of large scale screen display is adapted to, can draws in the content stream description of reference
The contents such as the picture with some commercial papers, and for the layout's description for adapting to small-size screen, its content quoted
The main contents such as word can be only quoted in stream description.Certainly, layout description with content stream description also and it is indefinite be one by one
It is corresponding, for example, the description of a variety of layouts can quote same content stream description, that is to say, that same content stream can be
A variety of layouts share.
S102:Layout is carried out to the display page according to layout's description information;
Document reader is after packet is got, it is possible to packet parsed, and first according to therein
Layout's description information carries out layout.That is, display frame is put up first, subsequently addition display thereto again
Content., can be first it should be noted that if the packet of certain electronic document includes Duo Fen layouts description information
Therefrom selection portion is currently needed for the layout's description information used.As it was noted above, specifically when being selected, Ke Yigen
According to critical data introduction described in packet to each part layout etc., the screen with present terminal equipment is automatically selected
A layout description of match parameters, or can also be specified by user.It has selected layout's description letter
After breath, it is possible to layout is carried out to the display page accordingly, equivalent to determining which includes respectively in each page first
A little page blocks, linking relationship between the size of each page block, the position at place and page block, etc..
S103:According to the content stream description information and the resource description information, determine content to be shown and show
Sample formula;
Due to illustrated in layout's description information quote content stream description information, and content stream description further through
Quote resource description to determine, therefore, it becomes possible to determine to be currently needed for the content and pattern of display.
S104:According to the Show Styles, in the display page of layout has been carried out, to the content to be shown
Carry out typesetting and display.
By step S102 and S103, equivalent to defining layout's framework of the display page, and need to this
What content is shown in framework, these contents have what kind of pattern (including font, font size, color etc.), so, then by these
Content carries out typesetting and display according to such pattern in the page for put up framework.
Wherein, a page block or page block chaining combination can quote one or more content streams, specifically to electronics
When document is shown, carried out during imposition layout according to content stream sequencing, chain is used when a page block is booked
The next page block being connected to continues typesetting.That is, according to Show Styles by content to be shown current page work as
Typesetting is carried out in preceding page block, after current page block is booked, according to the ordinal relation between page block, by treating for not yet typesetting
Display content typesetting is into next page block, after each page block of current page is booked, by the to be shown of not yet typesetting
Content typesetting is into the page block of next page, until all contents to be displayed are typeset completion, it is possible to shown.
For example, it is assumed that it is divided into three page blocks in first page, respectively page block A, page block B and page block C, wherein, the page
Block A is located at page block B and the page block C top, left-right situs between page block B and page block C, and each page block is respectively provided with
Frame;In addition, it is assumed that the sequencing between page block is described as:Page block A- > page block B- > page blocks C.Then specifically exist
When showing electronic document, content to be displayed is filled into page block A first, is booked in page block A and then to page block B
Middle filling, after page block B is booked, then fill into page block C, after page block C is also booked, continue into next page
It is filled, untill all contents to be displayed are all filled and are shown in the page.
Specifically in display, can be shown directly according to the result of typesetting on correspondence position corresponding to content to be displayed.
Also, after display, adjustment entrance can also be provided, can be with if user wants the Show Styles of the specific element of modification
It is adjusted by specifically adjusting entrance.Accordingly, reader is after the adjust request of user is received, it is possible to member
Plain pattern is modified.It can specifically include:
Color, background etc. are changed, this replacing only covers without typesetting again and uses new the rendering style;
Change font:Because different fonts character duration may be variant, it may be considered that put using only line position, in the line then
Relative position is adjusted by typesetting again;Can also the typesetting again in units of the page block after link, but the position of page block
Do not adjust;
Change font size:Can the typesetting again in units of the page block after link, when content be not enough to fully support page block or
When person's content is excessive, on the premise of big adjustment is not done to layout, page block size can be suitably adjusted, it is allowed to which content is overflow
Go out.
That is, in the embodiment of the present application, on the premise of layout is fixed, the content and pattern that are particularly shown
Can be according to the different and different of content stream description, and can also be adjusted according to the demand of user, there is very big spirit
Activity.
In a word, in the embodiment of the present application, because electronic document can use layout, content stream, resource such three
Layer description, therefore, document reader can carry out layout to the display page first when showing electronic document, equivalent to
Display frame has been built first, then according still further to the content stream description of reference, in specific resource in the display frame of the page
Hold and carry out typesetting and display.So, the characteristics of can embodying format is seen on the whole, because the layout position information in the page
It is fixed, and from local, the characteristics of flowing content can be retained again, so that electronic document has in typesetting and display
There is certain certainty, while also there is certain flexibility ratio and the free degree.
Further, since overall page layout using format mode define fixed size, fixed position space of a whole page block, therefore,
Enhance the rich and certainty of space of a whole page description;Page block or the content of its combination are described using streaming fashion, logical relation
Clearly.Local font, color, pattern etc. can be adjusted flexibly in the case where not influenceing total arrangement.
In actual applications, user is during an electronic document is browsed, may different layouts it
Between switch over.For example, it is assumed that initial user is browsed by the way of transverse screen, then can be according to the space of a whole page corresponding to transverse screen
Layout description carries out typesetting and display, afterwards if user rotates terminal device, makes portrait layout mode into and is browsed, then also may be used
Typesetting and display are carried out to be switched to layout's description corresponding to portrait layout.When equipment rotates, reader, which can be recorded, works as
It is preceding where to have browsed to content stream, after switching layout, where can jumping directly to this partial content
The page.It should be noted that changed due to switching front and rear layout, thus in each page start-stop position it is interior
Appearance is not necessarily identical, but the information such as paragraph due to still remaining with article in content stream, and records and have each version
The corresponding relation of the lower content of face layout, therefore, as long as the position that jumps to afterwards of switching substantially it is identical with the position before switching i.e.
Can, for example, being located at identical paragraph.Certainly, if in layout's description and content stream description, to the big of page block
Small, element pattern etc. is controlled so that total page number, the content of each page start-stop position under same size horizontal/vertical screen state
Unanimously, the page location for needing to jump to after switching can so be better controled over.Such as, it is only necessary to browsed before recording rotation
To how many page, after being switched to the layout of portrait layout and completing typesetting, jump directly to the page and shown.Separately
Outside, in actual applications, in addition to the switching between horizontal/vertical screen, it can also happen that switching between other layouts, such as
User has found that font is somewhat small under current layout, then can be manually switched to another layout, etc., but either
Which kind of switching, it can record and browse position corresponding positional information in content stream description before switching, after switching, jump
Go to the page corresponding to the position.
It is described above to describe the process for how showing electronic document, and meet the electronics of logic described in the embodiment of the present application
Document specifically when making electronic document, can follow the steps below making, it is necessary to made in advance by producer:
First, it is that the big section article (or " core article ") listed in catalogue creates the page under different layouts,
And page block can be added in the relevant position of these pages, according to schedule the order of typesetting output content, by specific page
Face block is chained up from front to back, forms page block chaining group.
Then, content stream is created for core article, describes and quote for establishing resources such as word therein, pictures, according to
Layout requires, is created for paragraph, word segment etc. and sets pattern;It is contemplated that same content stream in a variety of versions when making
The lower shared situation of face layout.
Finally, then by one or more content streams page block or page block chaining group are associated with.
In a word, when making electronic document, it is necessary to each layer information is described, indicates that reference between layers is closed
System, the related data for the electronic document finally made can be saved in into packet, and loaded and displayed is carried out for document reader.
It should be noted that in actual applications, specifically when making electronic document, it can be used according to above-mentioned logic
The mode of hard coded is realized, namely directly each layer information and its adduction relationship etc. be described using language such as XML.For
Cause producer more easily to produce the electronic document that meets above-mentioned logic, improve efficiency, reduce and producer is encoded
The requirement on basis, the embodiment of the present application can also provide a kind of method for generating electronic document, can be by " electricity during specific implementation
The application programs such as subdocument editing machine " perform, and referring to Fig. 2, this method may comprise steps of:
S201:For specified document content, the page, and record page attribute information are created;
In actual applications, the editing machine can provide a user interface for producer, and user interface can be divided into
Accessorial Tools Storage and preview region etc., producer can use the instrument in Accessorial Tools Storage, be performed in preview region and create the correlations such as the page
Operation.Wherein, each " instrument " equivalent to encapsulating respective method, when instrument on foreground by use, while showing,
Backstage can performs corresponding method, realizes corresponding function.
For example, when needing to create the page, the instrument therein for being used to create the page just can be used in producer, for example,
Certain button etc. is clicked on, accordingly, the signal as the page such as square frame can be shown in preview region, and with mouse drag etc.,
The size of square frame can be changed, meanwhile, the dimensional values of square frame can be gone out with dynamic calculation from the background, and enter action in the interface of foreground
State is shown, for producer's reference, etc..After producer determines the size of the page, backstage records the chi of lower page
Very little numerical value, preserved as page attribute information.At the same time it can also be provided as page addition frame, set page back gauge, the back of the body
Scape, whether full frame instrument, producer can select corresponding to instrument complete specifically to operate, accordingly, backstage meeting
It recorded in page attribute information.Certainly, the page attribute information such as the size of the page, back gauge, background, can create each page
When respectively specify that or specify unified page attribute information for full text shelves, namely cause each page that there is identical attribute.
Which kind of mode is specifically used, can be determined according to the demand of reality, here without limiting.
S202:Page block is created in the page, position of the page block in page is recorded in the attribute information of page block
Put and size;The page block is the subregion of viewing area in page;
After the page is created, it is possible to page block is added in page.It is used for accordingly specifically, still can provide
The instrument of page block is created, because page block is the subregion of viewing area in page, therefore, square frame can be equally used in preview region
Zoomed in and out etc. the size for carrying out representation page block, and by dragging the modes such as mouse;Simultaneously as page has been created before
