A method and system for processing electronic books adapted to screen resolution

technical field

The invention belongs to the technical field of electronic reading materials application, and in particular relates to an electronic reading material processing method and system adapting to screen resolution.

Background technique

The popularization and application of computer networks has led to the rapid development of electronic books. Due to its unique convenience, more and more people like to read electronic books through computers or other devices. Common electronic books include electronic books, electronic dictionaries, E-newspapers, e-magazines, and e-journals, etc.

Currently, there are two types of layout sizes for e-books. One is to automatically adjust the layout size according to the size of the display screen. However, this method requires re-layout when displaying, and cannot reproduce the original original version, and re-layout A large number of calculations are required to cause low efficiency; the other is a fixed layout size, which can achieve the original display effect and high display efficiency. Currently popular electronic books based on flash technology belong to the latter category. However, this method cannot be adjusted according to the resolution of the user's display screen, nor can it be dragged. It can only be displayed at a fixed place on the user's screen with a fixed size. If the layout of the electronic book is too large, it exceeds the resolution of the screen Then it is impossible to view all the content of the e-book, which will affect the user's reading of the e-book. For example, if the effective layout size of the e-book is set to 1024*768 or larger, then in this case, users with a low resolution of 800*600 will not be able to read the e-book. Read the complete e-book information, part of the e-book information will be cut off by the screen; that is to say, the current screen reading of e-books usually cannot adapt to the resolution size of the screen. In order to solve the above problems, ensure that the e-books can be completely displayed , the existing e-books are produced with a layout size that can guarantee the minimum display resolution of the compatible screen, which can be compatible with early 800*600 screen resolution users, and the layout size of e-books is also limited to 800*600 Within the size range, even if the resolution of most user screens is already higher than this size, such as 1024*768, 1280*1024 or 1600*1200, the screen area of most people will be sacrificed.

If the layout size of e-books can be adapted to the screen resolution, that is, the layout can still be displayed in an appropriate way at an early resolution, the reading area of most people's screens will be more fully utilized.

When reading in full-screen mode, adjust the layout size of the e-book to the actual resolution of the screen before displaying the content of the e-book, so as to ensure that all the content in the layout of the e-book can be displayed on the screen;

In this embodiment, the user wishes to see all the contents of the electronic periodical. According to the prompt of step (1), the resolution of the screen is smaller than the layout size of the electronic periodical. Therefore, the user selects the full screen mode to read the electronic periodical. At this time, the electronic All content in the journal is regarded as an image, according to the scaling ratio between the actual resolution of the screen (800*600) and the layout size of the electronic journal (1024mm*768mm) (the scaling ratio of the length is: 800/1024; the scaling ratio of the width Ratio: 600/768) Scale the entire layout of the electronic journal and adjust it to the actual resolution of the screen, that is, take the entire layout of the electronic journal and all the content in the electronic journal as an image, and after scaling the image, Adjust the layout size of electronic journals from 1024*768 to the actual resolution of the screen, which is 800*600, as shown in Figure 3, users can read and browse;
