Seamlessly transitting currently in order to realize animation, main method is to utilize window server to create top window
Mouth group, based on top group of windows establishment RWsSprite as the container of animation, can decode gif
Become two bmp pictures of the subsidiary mask figure of multiframe, and add in RWsSprite container, activate and hold
Device shows one group of animation.
If desired for seamlessly transit to another group animation method have two kinds:
1. create new RWsSprit container, activate display after adding new animated content, delete former simultaneously
Container, as shown in Figure 1；
2. delete the animated content of former RWsSprit container, add new animated content, such as Fig. 2 institute
Show.
If it is known that animated content to be seamlessly transitted, can be simultaneously by content to be play with wait to put down
The content of sliding transition cartoon together decodes to be put into a RWsSprit container and plays out, because container can
With the animated content therein of loop play in order, it is also possible to realize the effect that animation seamlessly transits.
Existing animation smooth transient method has the disadvantage in that
1. EMS memory occupation is many.If wanting container to show animated content, first need in animation to be shown
Appearance is decoded into after meeting form adds in container.The image parameters of RWsSprit container reception requires
8 gray scales bmp of one 24 true color bmp and its correspondence are as shade, and bitmap is a kind of picture
Element file, all of pixel in its preservation piece image, individual bmp picture size and color figure place
Relevant with dimension of picture, the internal memory shared by 24 true color pictures of a 240*320 size is big
General is 256K, and the gray scale picture of 8 is 86K.If one group of animation is made up of a lot of frames,
So joining the memory size shared by the picture in container is animation totalframes * (24 bmp figures
The size of+8 bmp bitmap committed memories of the size of sheet committed memory), EMS memory occupation amount is the most surprising,
The properly functioning of mobile phone can be directly affected.
2. decoding delay.If animated content is made with one group of animation (gif) or plurality of pictures sequence
Using for external file, when one group of animation file is excessive, (gif file is more than 80K or multiple are bigger
Image content), the decoding time linearly increases with file size or number of files, seamlessly transits two
There will be obvious time delay when organizing big animation file, lose the real-time of event response；
3. control freedom degree.When RWsSprite container contents has been filled, RWsSprite container meeting
Loop play animation file therein content.Because the control method that container provides is more single, for
The animated content putting into it can not arbitrarily control playing sequence and broadcasting time, and can only sequential loop
Play.In this motion seamlessly transit to next group animation before intercut a transition cartoon, and requirement
The transition cartoon intercutted only is play one time, uses existing technology to send out and is difficult to accomplish that freely controlling animation broadcasts
Put forward sequence.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that this place is retouched
The preferred embodiment stated is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Below with reference to Figure of description, describe the present invention in detail.
Generally animation file can be single gif/swf or one group of sequence of pictures, if with one group of animation
(gif/swf) use as external file, when one group of animation file is excessive (gif file is more than 80K),
The decoding time linearly increases with file size, seamlessly transits time delay increase thus causes event response real
Shi Xing.Therefore the present invention uses one group of png sequence of pictures to express an animation.
As it is shown on figure 3, the method that mobile phone desktop animated content of the present invention seamlessly transits mainly includes as follows
Step:
At the preset initial animation of mobile phone, terminate animation, transition cartoon and animation configuration file, generate
Initiating is drawn queue, is terminated animation queue and transition cartoon queue, according to initial animation queue, terminates moving
The information drawing queue, transition cartoon queue and animation configuration file generates animation display queue；
Sequentially read the animation index value in animation display queue, obtain picture according to animation index value
Positional information；Positional information according to picture reads the png picture of band alpha passage in mobile phone, right
The png picture read is decoded generating the bmp picture of band alpha passage, then through pixel
Number and byte-aligned, be decomposed into one without alpha passage by the bmp picture of band alpha passage
True color bmp picture and a gray scale picture；
Buffering is used to process the true color bmp picture without alpha passage and ash every time generated
Degree picture, container plays out.
The method seamlessly transitted based on animated content, is primarily directed to the switching between any two groups of animations
Realization seamlessly transits, and broadcasts one group of transition cartoon realize animation by adding between animation A and animation B
Effect is seamlessly transitted between content.
Often group animated content is made up of plurality of pictures sequence, and picture format can be selected for bmp, jpg, png
Deng common format.The method of the present invention uses png sequence of pictures, it is possible to achieve have transparent effect
Animation is play.Material needed for animation is play needs preset in mobile phone, and material includes initiateing, terminating
State animation and transition cartoon.One group of animation sequence is constructed by the method, suitable according to animation sequence
Sequence is play, then broadcasting between animation A to animation B can be made to realize content and take over seamlessly.
For realizing seamlessly transitting of animated content, according to animation character, all animations are divided into state and move
Picture, transition cartoon.State animation is the most initial or terminates animation, state animation multipass capable of circulation
Display；Transition cartoon is play between two sections of state animations, the most only plays one time, plays linking initial
Effect with final state animated content.
Use transition cartoon two state animations of linking, i.e. after completely playing first state animation
Inserting a transition cartoon, after transition cartoon completely plays one time, second state of recirculation broadcasting is moved
Draw.Concrete implementation:
The state animation that record is currently played is as initial state；
Final state animation is obtained as final state according to system or customer incident；
Read transition cartoon concordance list by the index value of two state animation place queues, obtain transition
The index value of animation place queue；
Constituted to be played dynamic with initial animation index value, transition cartoon index value and termination animation index value
Draw sequence.
For quickly calculating the transition cartoon index value obtained between two state animations, transition cartoon can be set up
Concordance list, uses two state animation indexes as the index of the corresponding transition cartoon of vernier quick search
Value.Transition cartoon concordance list carries out initializing structure by the local animation configuration file of scanning, specifically at the beginning of
Beginningization step is as follows:
According to state animation number, set up the concordance list of the transition cartoon of two dimension, be initialized as-1；
Scanning animation configuration file, sequential processing state animation and transition cartoon label (id and TID)；
The label reading transition cartoon is split into two parts, is recorded as horizontal stroke, vertical coordinate respectively；
Index value corresponding to transverse and longitudinal coordinate is entered as the position in this its queue of transition cartoon place.
A part of example of animation configuration file is as follows:
Wherein,<AN>label holds the information for state animation, and id represents state animation sequence number；<TAN>
Label substance is the information of transition cartoon, and TID represents transition cartoon sequence number.It is divided into according to TID is removable
The sequence number of corresponding states animation, is temporarily recorded as transverse and longitudinal coordinate, by the sequence number value assignment of this transition cartoon
Sit target value to corresponding transverse and longitudinal.
Transverse and longitudinal coordinate figure is the index value of state animation place queue, and the value in concordance list represents that transition is moved
Draw the index value of place queue.When given two state animations index value (a, b), with (a, b)
Taking out manipulative indexing tabular value for transverse and longitudinal coordinate figure, this numerical value is then that transition cartoon is in transition cartoon queue
Sequence number.The signal of the following table transition cartoon concordance list by being set up according to n web state motion picture.
The problem that animated content takes over seamlessly can be solved by the way of intercutting transition cartoon, but need
Preset animation quantity is wanted also to have increase, for reducing the number of transition cartoon, in two state animations
Add an intermediate animation, can effectively reduce the quantity of transition cartoon.Intermediate animation be one special
Animation, it is also possible to use as state animation.
It is required to it is assumed that have between n state animation, and any two state animation
During transition, the transition cartoon quantity of needs is n2, required transition cartoon quantity is more.As it is shown in figure 5,
If using intermediate animation to use as intermediate animation state, can convert to terminating animation from initial animation
First from initial animation to intermediateness, then from intermediateness to terminating animation, between all state animations
Transition cartoon quantity is then 2n, and the quantity of transition cartoon can be greatly reduced.
When being triggered switching animation by system or customer incident, need to use current animation state and termination
Transition cartoon status retrieval transition cartoon concordance list, obtains the index value of transition cartoon, passes through index value
From transition cartoon retrieval animation file title, re-use animation playing module and realize animation switching,
Implement step as follows:
When receiving the event of switching animation, current state animation is designated as initial animated state, new thing
Animation produced by part is designated as terminating animated state；
Check initial state animation or final state animation, if being not intermediate animation, then at two
Insert intermediate animation between animation, then become from original one group of animation (initial animation is to terminating animation)
Two groups of animations (initial animation-intermediate animation-termination animation)；
Resetting animation display queue value, initial value is-1；
Take out the initial animation numbering of first group of animation and terminate animation numbering, at transition cartoon mapping table
, if value is for-1, the most there is not transition cartoon in the index value of middle inquiry transition cartoon place queue, as
Fruit value is not-1, then add 1 by index value and negate, and joins animation display queue；
The termination animation of first group is numbered and adds animation display queue；
If there is the second group of animation situation of intermediate animation (add), use the animation of second group
Initial animation numbering and termination animation numbering, inquire about transition cartoon place team in transition cartoon mapping table
The index value of row, if value is not-1, then adds 1 by index value and negates, and joins animation display queue；
If there is second group of animation (adding the situation of intermediate animation), then by second group of transition cartoon
Termination animation add animation display queue；
According to the indexed sequential playing animation crossed in animation display queue, if index value is less than 0, then
Negate and subtract 1 and try to achieve correct index value, use index value to take out animation broadcasting from transition cartoon queue,
If index value is more than or equal to 0, then uses index value to take out animation from state animation queue and play.
Above index value inversion operation is because state animation and transition cartoon leaves two respectively in
In individual queue, in order to distinguish state animation and transition cartoon index value (index value all from the beginning of 0,
Sequentially it is incremented by), the index value of transition cartoon is added 1 every time and negate and be stored in, negate during taking-up and subtract one also
Former, state animation index value does not processes, can be according to the positive negative judgement animation place queue of index value.
Use transition cartoon concordance list can index with the transition cartoon between two animations of quick-searching, it is achieved
The broadcasting of animation need to decode display successively to the motion picture in the animation queue after calculating, and completes animation
Play.
Because the use of picture format is limited by platform so that can not directly use png form to read
Take display, and need extra picture to change；Further, translucent effect to be realized, system needs
Two pictures are overlapped realizing picture by the correspondence 8 bitmask picture in addition to real color bitmap
Translucent effect.
The principle of picture decoding is the inverse process of compression, can be according to code table information and compressed bit stream during decoding
Restore raw image data.The present invention uses the png decoder module of own coding to enter the picture loaded
Row decoding, generates the bitmap of 32 bit strip alpha passages, then to 32 bit strip alpha passages
Bmp does after-treatment, mainly includes that bitmap alignment and pixel number align, generates one 24 very
Two pictures just can be realized by colored bmp and 8 gray scales bmp as the input of display module
Transparent effect.
I byte-aligned
Structure is a kind of composite data type, its constitution element both can be basic data type (as int,
Long, float etc.) variable, it is also possible to be that some composite data type are (such as array, structure, connection
Close etc.) data cell.In the structure, compiler is that each member of structure is by its natural boundary
(alignment) allocation space.Each member deposits according to they declared orders order in internal memory
Storage, the address of first member is identical with the address of total.In order to enable CPU to variable
Quickly accessing, the initial address of variable should have some characteristic, the most so-called " alignment ".
The int type of such as 4 bytes, its initial address should be positioned on the border of 4 bytes, i.e. initial address
Can be divided exactly by 4.If spanning 4 bytes or less than 4 bytes all can reducing variables access speed.
Ii bitmap aligns
BMP (Bitmap-File) graphic file is the graphics file format that Windows uses, and is one
Planting pixel file, it saves all of pixel in piece image.This file format can preserve list
Color bitmap, 16 colors or 256 color indexing model pixel maps, 24 true color images, in each pattern
The size of single pixel is respectively 1/8 byte, 1/2 byte, 1 byte and 3 bytes.At Windows
Lower in order to accelerate the processing speed of CPU, a base line in Windows regulation image file
Shared byte number must be the multiple (i.e. in units of word) of 4, and not enough position is filled with 0.
When byte number shared by one base line of image is less than the multiple of 4, the size of data bitmap can not
Calculate according to the line width in bitmap header information, need to carry out extra cover and calculate.
Definition: the data length (nWidthBytes) of each row of pixels, color figure place (nBits),
Often row number of pixels (nWidth).
Monochrome bitmap: nWidthBytes=(nWidth+7)/8
4 color bitmaps: nWidthBytes=(nWidth+1)/2
16 color bitmaps: nWidthBytes=nWidth*2
24 color bitmaps: nWidthBytes=nWidth*3
32 color bitmaps: nWidthBytes=nWidth*4
The byte number that data line is actually used can be calculated, if byte number is not by above-mentioned formula
The multiple of 4, then need cover to calculate.In image file, the byte number shared by a base line is as the following formula
Calculate (in the case of not compressing):
Byte number=((nWidth*nBits+31)/32) * 4 needed for each base line. (1)
Such as one bitmap is 29 (wide) * 100 (high) pixel, then nWidth is 29, if position
The data scheming each pixel are 1 (usually 8 gray-scale maps, or 24 true coloured pictures), then nBits
Being 1, needed for each base line, byte is ((nWidth*nBits+31)/32) * 4=
((29*1+31)/32) 4=4 byte of *.After polishing, long each pitch of scanning is 32 (4 bytes),
As shown in Figure 6: 8 29 3 use 0 cover
Symbian system provides CFbsBitmap class management bitmap, is obtained by DataAddress ()
Removing the address pointer of internal storage data beyond pictorial information head, carrying out internal memory operation can be to picture
Internal storage data is modified.Symbian system have followed the byte-aligned principle of bitmap equally, with
