Description

Electronic document display method and device

technical field

The invention relates to the field of computer image processing, in particular to a method and device for displaying electronic documents.

Background technique

Many of the current e-readers have a reading mode that simulates the page-turning effect of a paper book. The feature of this page-realistic display is that it can truly reproduce the original appearance of a book and give users the original feeling of reading a paper book.

Due to the difference in screen size and resolution, most e-readers only support streaming documents in their page simulation display, and the book page size is scaled within the screen range according to a certain fixed ratio or simply fills the entire screen. For layout documents, there are two ways:

1) Fixed ratio method. Preset an acceptable page size within the screen range, and the document page will be scaled and displayed within this range to fill the visible area as much as possible, and the area that cannot be covered by the original page due to the inconsistency between the page and the screen ratio will be filled with the default color.

2) Home page method. Take the size of the first page of the document (or the agreed-upon page attribute), and display it as enlarged as possible within the visible range allowed by the screen, and display all other pages according to this ratio.

In the process of the existing virtual display of e-book pages, the inventor found that: the second home page method is effective for documents with a single page size, such as books, and the original version of the book can be seen on the terminal The pages on the website are displayed realistically, but for some documents with inconsistent page sizes, the reading effect of the entire document will not be optimal because the displayed size cannot fit most pages, which will reduce the user's reading experience.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

The electronic document display method provided by the embodiment of the present invention, as shown in FIG. 1, the method steps include:

S101. Determine multiple pages in the electronic document as reference pages.

Specifically, a certain proportion of discrete or continuous pages in the electronic document may be used as reference pages.

S102. According to the distribution of pages of each size in the reference pages, determine a display mode corresponding to pages of one size in the reference pages as a designated display mode for displaying electronic documents.

Specifically, the percentage of pages of each size in the reference page may be calculated; then, it is determined that the display mode corresponding to the size of the page whose percentage is greater than or equal to a predetermined percentage is the specified display mode for displaying the electronic document ( For example, the predetermined percentage may be any value between fifty percent and one hundred percent).

The electronic document display method provided by the embodiment of the present invention determines multiple pages in the electronic document as reference pages; according to the distribution of pages of each size in the reference pages, the corresponding The display mode is determined as a designated display mode for displaying the electronic document. In this way, when the page sizes of the documents to be displayed are inconsistent, all pages will not be displayed with the home page size or fixed page size as in the prior art, but can be selected according to the distribution of pages of each size in the reference pages. A most suitable page display ratio is displayed, so that most pages can be displayed with the best effect to the greatest extent, thereby improving the user's reading experience.

Embodiment two

The method for displaying electronic documents provided by the embodiments of the present invention can be applied to various terminals, such as PCs, handheld readers, mobile phones, etc., in the virtual reading mode of formatted document pages. Assume that a handheld reader is used as an example to read an electronic document with 100 pages, and the size of each page in the electronic document is different. As shown in Figure 2, the method steps provided in this embodiment include:

S201. Take a certain proportion of continuous pages as reference pages.

Specifically, an appropriate range of page numbers S∈[S ₁ , S ₂ ] can be extracted as the reference page according to the page number n of the entire document, where S ₁ is the start page and S ₂ is the end page, then 0≤S ₁ ≤S ₂ ≤ (n-1). To explain, in practical applications, the page number of a document is generally counted from 0, so a document with n pages, its page number is 0~(n-1). For example, the electronic document in this embodiment has 100 pages, if 10% of the continuous pages are taken, the 1st page to the 10th page can be taken.

In theory, it is best to take all the pages of the electronic document as reference pages, but due to the existing processor speed and network block reading, it is not practical to do so, so at present only a certain proportion of pages can be used as reference pages.

Of course, it is also possible to take a certain proportion of discrete pages as reference pages. If 10% of the total number of pages is still taken, 10 pages can be randomly selected.

S202. Calculate the percentage of pages of each size in the reference pages.

Specifically, in this step, pages with the same page aspect ratio may be regarded as pages of the same size. In this way, a part of the pages can be consolidated to make the calculation result closer to the actual situation.

Further, if pages of the same size (including pages with the same aspect ratio) appear consecutively, the pages may be weighted according to the number of consecutive appearances. The higher the number of consecutive appearances, the higher the weight, and the weight of two consecutive appearances is higher than the sum of the weights of two separate appearances.

For the electronic document in this embodiment, calculate the weight value of each occurrence of each page size separately. The calculation method can be enumerated from the first page until the 10th page in the reference page, according to the pages with the same aspect ratio The number of consecutive occurrences is multiplied by the corresponding weighted value.

S203. Determine that the display mode corresponding to the size of the page whose percentage is greater than or equal to the predetermined percentage is a designated display mode for displaying the electronic document.

Specifically, the weights of each occurrence of pages with the same page proportion may be added. Assume that x is the page size number; P _y is the weight when the page of the same size appears y times in a row; C _n is the consecutive number of nth consecutive appearances; ∑P _x is the total number of pages with the size number x in the reference page weights.

$\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}{\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; x</span>}}<span\; class="notranslate">\; =</span>{\mathrm{<span\; class="notranslate">\; P</span>}}_{{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}}}<span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; P</span>}}_{{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; +</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; .</span><span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; P</span>}}_{{\mathrm{<span\; class="notranslate">\; C</span>}}_{\mathrm{<span\; class="notranslate">\; no</span>}}}$

Find a page whose weighted percentage is greater than or equal to the predetermined percentage, and obtain the aspect ratio of the page, then scale the page proportionally according to the screen size, and display the electronic document in the scaled display mode The specified display mode for .

In addition, a page with the highest weighted percentage can also be found, and the electronic document can be displayed in a display manner corresponding to the size of the page.

Furthermore, there are two special cases. When S∈[0,0], that is, S ₁ =S ₂ =0, the default page size is obtained according to the screen resolution, and the corresponding display mode of the page with the default size is determined as The specified display mode used to display the electronic document. When S∈[0,1], that is, S ₁ =0, S ₂ =1, or S∈[1,1], that is, S ₁ =S ₂ =1, obtain the page size of the first page of the electronic document , and determine the display mode corresponding to the page of the size as the specified display mode for displaying the electronic document.

The electronic document display method provided by the embodiment of the present invention determines multiple pages in the electronic document as reference pages; calculates the percentage of pages of each size in the reference pages, and determines the pages whose percentage is greater than or equal to a predetermined percentage The display mode corresponding to the size of is the specified display mode for displaying the electronic document. In this way, when the page sizes of the documents to be displayed are inconsistent, all pages will not be displayed with the home page size or fixed page size as in the prior art, but can be selected according to the percentage of pages of each size in the reference page. A most suitable display ratio for the page is displayed, so that most pages can be displayed with the best effect to the greatest extent, thereby improving the user's reading experience.
