In ANDROID systems, the JAVA language of application layer can be used to call the C that can be run in the operating system layer of ANDROID systems
Language, it is the page Pixel Information distribution system internal memory by C language.In a kind of feasible pattern, NDK can be used
(Native Development Kit, primary kit) realizes the distribution of Installed System Memory.NDK is a kind of local developing instrument
Collection, can be used in ANDROID systems allowing C language and JAVA language to call mutually.In this step, NDK association can be used
View goes to call C language application system internal memory, as called void*malloc (size_t size) the function applications system in C language
System internal memory.But it should be understood by those skilled in the art that NDK is merely illustrative, in actual applications, those skilled in the art
Other similar means or mode can be used, such as SDK (Software Development Kit, SDK) etc.,
Realize the distribution of Installed System Memory.
Can either be institute according to the mode of the display pattern distribution system memory headroom of the e-book page to be shown
State page Pixel Information and distribute enough spaces, the waste of memory headroom can be avoided again.And for using application layer program language
The mode of call operation system layer program language distribution system internal memory is sayed, on the one hand realizes that the e-book page is corresponding for developer
Page Pixel Information Installed System Memory distribution provide convenient means, reduce development difficulty；On the other hand, also reduce for
The cost of implementation of page Pixel Information distribution system internal memory.
But the above-mentioned display pattern distribution system internal memory according to the e-book page to be shown is not limited to, actually should
In, those skilled in the art can also distribute the Installed System Memory of fixed size, the space of Installed System Memory for page Pixel Information
It is enough to store page Pixel Information corresponding to Most electronic page face.It is of course also possible to believe for the page pixel
Installed System Memory of the allocated size slightly larger than the display pattern of the e-book page to be shown is ceased, to be the page pixel
Information provides relatively abundant free space.
Step S206：The page Pixel Information is stored in the Installed System Memory of distribution.
Wherein, the page Pixel Information can using it is any it is appropriate by the way of stored.It is alternatively possible to distributing
Installed System Memory in create color array, use page Pixel Information described in color storage of array.Wherein, color array can be
Regular length array, the element in color array correspond with the pixel in the e-book page；Color array can also be
Variable-length array, the element in color array is corresponding with the pixel region in the e-book page, or, both can be with pixel region
Domain correspondingly can also be corresponding with pixel.Certainly, in actual applications, those skilled in the art can also use other appropriate sides
Formula passes through color array memory page Pixel Information.By color array memory page Pixel Information, color array and page picture
Correspondence between prime information is good, also, realizes that simply cost of implementation is low.If it should be noted that pass through SKBitmap objects
Page Pixel Information is obtained, corresponding color array can be directly obtained, is its distribution system internal memory and storage.
Alternatively, when the page Pixel Information includes the quantity and color value of pixel corresponding to the e-book page
When (such as ARGB values or rgb value or other color values)；, can be according to described when color array is created in the Installed System Memory of distribution
The quantity of pixel determines the quantity of the element of color array to be created, it is determined that the color value of pixel corresponding to each element；Root
According to the quantity of the element and the color value of corresponding pixel, color array is created in the Installed System Memory of distribution.And then use
Page Pixel Information described in the color storage of array of establishment.In such a mode, the element in color array can be with electronics page
Pixel in face corresponds.For example, when e-book page A has 100*50=5000 pixel, color array can be right
There should be 5000 array elements, the value of each array element is the color value of corresponding pixel.In storage, color array
Preceding 100 elements correspondingly store e-book page A the first pixel column 100 pixels color value, 101-200
Element correspondingly stores the color value of 100 pixels of e-book page A the second pixel column, by that analogy, 4901-5000
Individual element correspondingly stores the color value of 100 pixels of e-book page A the 50th pixel column.This mode stores simply,
Without extra pixel information such as identification information or coordinate information sign pixel.But not limited to this, the page pixel letter
Breath can also include the identification information and/or coordinate information of pixel, clearly to indicate each pixel, in such cases, face
Each element in chromatic number group includes the identification information and/or coordinate information of pixel in addition to the color value including pixel.Using
This mode, it can be also convenient for subsequently to e-book while quickly page Pixel Information corresponding to the display e-book page
The positioning and operation of some pixels in the page.
Step S208：According to the page Pixel Information of storage, the e-book page to be shown is shown.
The corresponding e-book page can be shown by page Pixel Information.
In a kind of feasible pattern, the page Pixel Information can be obtained simultaneously from Installed System Memory by graphic package interface
Send to display card, by showing that card shows the page Pixel Information, to show the corresponding e-book page.Wherein, show
Card can be by those skilled in the art's display card arbitrarily appropriate according to use is actually needed, including but not limited to GPU
(Graphics Processing Unit, graphics processor).Graphic package interface provides convenient graph image drafting side
Formula, and the complicated realization of bottom hardware can be shielded so that the drafting of page Pixel Information is more easy to corresponding to the e-book page
In realization, development difficulty and cost of implementation are greatly reduced.
Wherein, graphic package interface includes but is not limited to OpenGL.OpenGL defines one across programming language, cross-platform
DLL specification professional graphic package interface, it is unrelated with hardware, can easily carry out 2D or 3D graph images
Drafting.By OpenGL, the drafting of page Pixel Information corresponding to the e-book page can be conveniently realized.But it is not limited to
OpenGL, such as other manner, Unity are equally applicable.For example, pass through the SKBitmap object acquisitions of bottom electricity to be shown
The color array of the philosophical works page, then by OpenGL color array pass to GPU (Graphics Processing Unit,
Graphics processor), it is eventually displayed on screen, thus avoids in conditional electronic book page display way, it is necessary to will
The information copy of SKBitmap objects takes the situation of application memory to application layer.
By said process, while the displaying of the e-book page is realized, it is thus also avoided that because bitmap takes too many application
Internal memory and the situation for causing e-book reading application crashes.
Based on said process, what those skilled in the art can also carry out following step S210-S212 can selection operation.
