Embodiment
The invention provides a kind of processing method of mobile terminal cartoon.Wherein, the portable terminal encoder is resolved the view data part in the mobile terminal cartoon flash file format, and the view data that the vector in this form is described is converted to the raster image data, and detailed process is as follows:
The Flash file format is disclosed file format, this document format content mainly comprises two parts, and first is that vector graphics is described part, and second portion is an animation action description part, need resolve first in the time of the conversion figure, be an example of first's file format below:
Shape id=1 Rect bitsize=13 (1250,1730)-(2570,1750) (border of assignment graph)
Fill RGB (0,0,0) (the appointment Fill Color is a black)
Line-style width=20RGB (0,0,0) (specifying live width is 20 units of flash form)
Move 1260,1740 (paintbrush move to the flash form 1260,1740 this
Individual point)
Line 1300,0 (drawing 1300 units of flash form to the right)
This one piece of data has just been described the drawing process of a black horizontal line, can programme to parse this part content, uses the drawing image function of C# language to draw out then in the same old way, generates the raster image of a png form then, for future use.
Though the part of the pattern description in the Flash file format is versatile and flexible, it also is rich and varied describing the figure that comes out, and its data content is all followed this form basically, so all can resolve and draw by programming.
Vector graphics is converted to the real-time rendering of having avoided portable terminal behind the raster image.Use the GZip compression algorithm to compress then, because the raster image that the vector graphics conversion gets generally all is the lower image of relative complex degree, so use GZip compression algorithm compression effects very good, can be owing to vector animation being converted to the significantly increase that raster image brings the visuals data volume.
The recycling rate of waterused of same graphic element very high (animation such as one 200 frame may only need 60 graphic elements just can express plot) for animation, so the data file that obtains at last is very little, be adapted at transmitted over wireless networks, and the figure quantity that need be written into also significantly reduces, and has improved the efficient of decoder.
Encoder is resolved the operation control part branch (as translation, rotation, convergent-divergent) in the flash form then, these control datas is converted to the control data of own control raster image.Be the example that operation control part is divided in the flash file format below:
place-object2 id＝1 depth＝1 clip＝0 ratio＝-1 name＝null
Matrix(Sx，sy，s0，s1，tx，ty)＝(1.0，1.0，0.0，0.0，0.0，0.0)null
----------frame----------
The content that this segment data is described is: is id to be placed on 1 layer after this figure of 1 is not done any convergent-divergent and rotation, and its gating matrix is 1.0,1.0,0.0,0.0,0.0,0.0 gating matrix is a key concept in the computer graphics, comprises 6 control elements, be respectively sx, sy, s0, s1, tx, ty respectively is: horizontal convergent-divergent, vertical convergent-divergent, transverse translation, longitudinal translation and two anglec of rotation control elements.
The present invention need decode the graphic element that all need show when decoding is play, control according to the order of control data frame by frame then, so the internal memory that needs is bigger, yet the memory headroom of considering portable terminal is very limited, so, coded format of the present invention has adopted branch scene mechanism, promptly an animation is divided into a plurality of scenes according to plot, decoder is written into according to the scene order and decodes when playing, be written into and the scene of having decoded after begin to play this scene, carry out being written into of next contextual data in the playing process simultaneously, after playing this scene, carry out the decoding of next scene, begin after decoding is finished to play, repeat this process then and finish up to whole animation.In synchronization portable terminal internal memory, only need deposit all data of a scene rather than all data of whole animation so, also just solved the less problem that can't all be written into of portable terminal internal memory, and owing to the broadcast and being written into simultaneously of next contextual data of current scene are carried out, so realized online broadcast.
Branch scene mechanism has been mainly the limited problem that can't once be written into all images of an animation of portable terminal internal memory that solves.If the full content of an animation is exactly an object parallel moving on picture, so only need a scene just passable, because the amount of images that whole animation comprises is one, portable terminal only need be written into this image once, just can repeatedly draw the effect that gives expression to translation.For example: background all is that the picture of an automobile is set to a scene, like this, during coding, only need preserve less view data to every width of cloth picture, and when playing, renders raw frames on same scene.
If an animation more complicated is a complete story, so just should be divided into a plurality of scenes according to plot.
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.
Encoder moves on computers, is the core that generates the tools of animation file.Decoder moves on portable terminal.After utilizing tools to make what a animation file, to upload onto the server by Content Management Platform, mobile phone users just can access server and is downloaded and watched these animation files.
Fig. 1 is the coding work schematic flow sheet of mobile terminal cartoon of the present invention.As shown in Figure 1, comprising:
Step S101 determines the scene switching point according to plot;
Step S102, encoder is divided into a plurality of different scenes to the flash file according to the switching point of appointment;
Step S103, encoder resolve the vector image data of current scene in the flash file, and with the vector image data storing in internal memory, for example:
Shape id=1 Rect bitsize=13 (1250,1730)-(2570,1750) (border of assignment graph)
Fill RGB (0,0,0) (the appointment Fill Color is a black)
Line-style width=20 RGB (0,0,0) (specifying live width is 20 units of flash form)
Move 1260,1740 (paintbrush move to the flash form 1260,1740 this
Individual point)
Line 1300,0 (drawing 1300 units of flash form to the right)
The vector that the developer can use the System.Drawing.Drawing2D.GraphicsPath object in the C# language to store this figure is described;
Step S104, encoder use the DrawPah method of System.Drawing.Graphics object that this object is plotted as raster image, use the System.Drawing.Bitmap object that raster image is stored as the png picture at last;
Step S105, encoder stores in the internal memory after using free kit GZIP with the png picture compression then;
Step S106, encoder is resolved the action control data in the flash file, for example:
place-object2 id＝1 depth＝1 clip＝0 ratio＝-1 name＝null
Matrix(sx，sy，s0，s1，tx，ty)＝(20.0，20.0，0.0，0.0，0.0，0.0)null
----------frame----------
The critical data of action control data is the deformation matrix (20.0,20.0,0.0,0.0,0.0,0.0) of id and back, and deformation matrix has been expressed the conversion that need do the graphic elements of specifying id, comprises translation, rotation and convergent-divergent.Preceding two data are represented translation of x axle and the translation of y axle, unit is 1/20 pixel, purpose is the accuracy when guaranteeing under calculating different size ratio translation position, because computer screen is very big, the situation of animation size may appear changing in the user in playing animation, for example full frame or dwindle, so this design is necessary, but mobile phone screen is very little, the user can not change the size of animation in playing animation, the size of having only a kind of played in full screen is so only need get final product according to the storage of actual size value.After decoder parses id and deformation matrix, these critical datas are converted to own data format, be that unit is the data format of 1 pixel, append the view data back of storing into after the compression of GZIP compression algorithm then, for example above this section control data after conversion and formats stored be:
| id | The X-axis translation | The Y-axis translation | Be rotated in the forward | Counter-rotating | The X-axis convergent-divergent | The Y-axis convergent-divergent |
| 1 | 1.0 | 1.0 | 0.0 | 0.0 | 0.0 | 0.0 |
Step S107, scene ground of scene of encoder is after all images data and the processing of action control data and storing internal memory into, be written to together in the last animation data file, upload onto the server by Content Management Platform, mobile phone users passes through access server, all download or download this animation file to the internal memory of portable terminal, utilize the broadcast of decoding of the built-in decoder of portable terminal by scene.
Whole processes of back playing animation of downloading are with basic identical by the process of scene download and online playing animation, difference is, the former is direct local file reading of data after download during broadcast, rather than as the file that reads of the service end of the latter from the network, owing to read local file than faster, so situation slowly can not occur playing because network is busy from the service end reading of data.But the internal memory that the former takies but will be far longer than the latter's the scene of pursuing and download the employed internal memory of animation.Less relatively in view of the memory headroom of common portable terminal, so following further elaboration is downloaded by scene, realize the concrete steps of online broadcast.
Fig. 2 is the decoding workflow schematic diagram of mobile terminal cartoon of the present invention.As shown in Figure 2, comprising:
Step S201, decoder download the data of first scene to internal memory, begin to resolve;
Step S202, decoder earlier carry out decompress(ion) according to the GZIP compression algorithm to view data and contract and be stored in the internal memory, and the implementation method that the GZIP on the brew development platform decompresses is:
int32 IUNZIPASTREAM_Read(
IUnzipAStream*pIUnzipAStream，
void*pBuffer，
uint32 dwCount)
On the portable terminal development platform of all main flows, all provide the decompression function of GZIP compression algorithm directly to call;
Step S203, decoder decompress(ion) go out to move control data and are stored in the internal memory;
Step S204, after finishing, the current scene data parsing begins to play each two field picture of this scene according to the action control data, can be during the broadcast of each two field picture and in the interim of adjacent two two field pictures broadcast, select any one section or All Time, download the data (with reference to step shown in Figure 3) of next scene.
Fig. 3 is the present invention downloads mobile terminal cartoon in the interval that every scene is play frame by frame a workflow schematic diagram.As shown in Figure 3, in the interim that each scene is play frame by frame, download the data of next scene among this embodiment, specifically comprise:
Step S301, the image of first frame of this scene of mobile terminal playing;
Step S302, the interim after first two field picture finishes, the data and the preservation of downloading next scene;
Step S303 begins to play second two field picture of this scene;
Step S304 after second two field picture finishes, continues to download the data of next scene and preserve;
Step S305, by that analogy, the select time section is downloaded the view data of next scene in the interim that this scene image is play frame by frame, finishes until the image of this scene last frame.
