Embodiment
In the technical scheme provided by the invention, its main technical schemes is: frame picture and the corresponding initial coordinate of obtaining next frame to be played; Obtain the position of described frame picture and the side-play amount of primitive frame picture position; According to described side-play amount described initial coordinate is revised, obtained the actual coordinate of described frame picture; Show described frame picture at described actual coordinate.
Below in conjunction with the accompanying drawing among the present invention, technical scheme of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The method that the embodiment of the invention provides a kind of animation to play as shown in Figure 1, specifically may further comprise the steps:
The side-play amount of step 102, the position that obtains the frame picture and primitive frame picture position.
The embodiment of the invention is revised the position of role's variable in painting canvas by obtain the actual coordinate of frame picture when playing, and the memory headroom that has taken when not only having saved the storage of frame picture has reduced the calculation consumption that is fused to painting canvas when the frame picture shows simultaneously.
The frame sequence that animation is made up of a series of static frames presents frame by frame according to time series and to form.Each frame picture is stored in the internal memory in advance, when playing animation, each frame in this frame sequence is imported in the animation soft one by one, each frame picture is played back continuously again.When per second was continuously play 24 frames, people's naked eyes can not differentiated each frame picture, thereby what present is continuous animation effect.
Role animation is meant that role's variable moves in a big painting canvas or in the picture scene.Wherein role's variable correspondence two data, the frame picture data that data are this role's variable, this frame picture data is the bitmap of a matrix form, is used to present the tableaux of this role's variable; Another data are the logical coordinates of this role's variable correspondence, and this coordinate carries out the coordinate of correspondence when mobile on painting canvas for this role's variable.From the above, each tableaux of role animation is finished by the frame picture, and the action of role's variable is finished by the frame of continuous broadcast in the role animation, and the role's variable in the role animation moves by the logical coordinates combination of role's variable with respect to the position of painting canvas and finishes.
For example: the picture that role animation will present is that an owner is leading a doggie to take a turn in the park.When owner was leading doggie to take a turn in the park, the tableaux of each corresponding moment was finished by the frame picture of this role animation; Owner is leading the dynamic action of doggie stroll to be finished by the above-mentioned frame picture of continuous broadcast, but this moment owner and doggie be constant with respect to the position of painting canvas, only be the stroll of carrying out the original place; The evolution that owner is leading doggie to take a turn in the park to produce is then finished by the conversion of the logical coordinates of role's variable of this role animation, and a series of logical coordinates forms the track of motion, thereby produces the evolution of role's variable.
Based on above-mentioned analysis, the method that provides a kind of animation to play in the embodiments of the invention, its main technical schemes is:
This method mainly comprises two steps: cut the primitive frame picture (1), and storage is cut back frame picture and cut the side-play amount of back frame picture position with respect to the primitive frame picture position.(2) revise cutting back frame picture corresponding initial coordinate according to the side-play amount of storage, obtain the actual coordinate of this cutting back frame picture correspondence, and show this cutting back frame picture at this actual coordinate place, realize the broadcast of animation by frame picture after the cutting of replacing current demonstration continuously.
Below at first to the cutting primitive frame picture described in the above-mentioned steps (1) and store this frame picture and corresponding side-play amount is described.Concrete, the frame picture of next frame to be played that obtains needs process frame picture cutting process in advance and stores accordingly, following flow process provides a kind of method of animation storage, during the storage frame picture, white space to the frame picture cuts, replace the primitive frame picture with cutting back frame picture and store, as shown in Figure 2, specifically may further comprise the steps:
Concrete, obtain the frame picture that does not carry out the white space cutting, its corresponding frame picture data be frame1}, this frame picture data is the bitmap of a matrix form, is used to present the tableaux of this role's variable, this moment, the size of each frame picture was.
In this flow process with the horizontal ordinate of the primitive frame picture institute overlay area that obtained for (X11, X12), ordinate is that (Y11 Y12) describes for example, specifically as shown in Figure 3.
In the primitive frame picture that is obtained in step 201, owing to do not carry out the white space cutting, the size of each frame picture is the same, but is not that each primitive frame image content has been covered with whole painting canvas fully in fact, and many white spaces are often arranged.And these white spaces committed memory not only, and merge in animation display and scene and to consume the CPU computational resource when calculating.Therefore the white space of primitive frame picture need be cut away, reduce each frame picture taking and computational resource internal memory.
Concrete, cut away the white space of frame picture, as shown in Figure 4, may further comprise the steps:
A) discern the primitive frame picture nontransparent pixel on four limits up and down.
B) obtain above-mentioned primitive frame picture the ordinate of orthogonal axes Y21 and the Y22 of the nontransparent pixel on both sides, wherein Y21＜Y22 up and down; And the transverse axis coordinate X21 and the X22 of the nontransparent pixel of above-mentioned frame picture the right and left, wherein X21＜X22.
C) calculate the upper left side side-play amount of cutting back frame picture position with respect to the primitive frame picture position.
The non-blank-white zone that the primitive frame picture cuts the back gained is cutting back frame picture.The non-blank-white zone can be regular shape or non-regular shape, preferably, is that rectangle is that example describes with the non-blank-white zone in the embodiment of the invention.
So the non-blank-white zone that obtains in the above-mentioned steps is by X21=0, X22=0, four straight lines of Y21=0 and Y22=0 surround;
For conserve storage, preferably, will cut back frame picture in the embodiment of the invention and be offset to the upper left side, overlap until upper left side with the primitive frame picture.At this moment, the upper left side side-play amount is fX=X21-X11, fY=Y12-Y22, and wherein fX is the side-play amount of this frame picture transverse axis, and fY is the side-play amount of this frame picture longitudinal axis, and its zone is among Fig. 4 shown in the dash area.
Need to prove that the side-play amount of cutting back frame picture adopts the upper left side side-play amount of cutting back frame picture position with respect to the primitive frame picture position in the embodiment of the invention, only is preferred embodiment a kind of.The parameter that move the every position that can embody the frame picture of cutting back frame picture before with respect to cutting all can be used as side-play amount, serves as preferred with conserve storage wherein.
Concrete, storage cutting back frame picture and cutting back frame picture position may further comprise the steps with respect to primitive frame picture position upper left side side-play amount:
A) according to frame picture after the cutting that step 202 obtained, this cutting back frame picture is stored as new frame picture, substitute the primitive frame picture, the frame picture data is { frame 1 ' } after this cutting back frame picture corresponding cutting.
B) the frame picture position is with respect to frame picture data { frame 1 ' } after the upper left side side-play amount of primitive frame picture position and the cutting back frame picture corresponding cutting after the cutting that obtained of storage, and its file layout is { frame 1 ', fX, fY}.At this moment, because the frame picture has carried out the cutting of white space, so this moment, each frame picture dimension varied in size.
Corresponding above-mentioned steps (2), the embodiment of the invention provide a kind of method of animation broadcast, obtain the actual coordinate of frame picture during to broadcast, revise the position of role's variable in painting canvas and are described, and as shown in Figure 5, specifically may further comprise the steps:
The initial coordinate of role's variable is this role's variable carries out correspondence when mobile on painting canvas a coordinate.Regard this role's variable as a some this moment, the initial coordinate of obtaining this role's variable for (rX, rY), specifically as shown in Figure 6.Among the figure,, replace this role's variable as the position of point in painting canvas with the position of circle in painting canvas for clear.
Need to prove that the relative position of this role's variable and painting canvas is a kind of preferred implementation in the embodiment of the invention, in the role animation of reality, this role's variable can be positioned at the optional position on the painting canvas; Regarding role's variable as a point is a kind of preferred implementation, is convenient to explanation and shows, but be not limited to this, and can select any point on the frame picture of this role's variable correspondence is that benchmark calculates and shows.
The frame picture data of next frame to be played is the frame picture that cuts away behind the white space in this flow implementation example, its data be frame ' 1}, and carry upper left side side-play amount { fX, the fY} that is used to revise this frame picture corresponding initial coordinate.
Because the initial coordinate of in step 501, being obtained for role's variable of the frame picture correspondence of next frame to be played, when not carrying out the white space cutting for the frame picture of this role's variable correspondence, this role's variable corresponding coordinate on painting canvas.And the frame picture data of next frame to be played that is obtained in the step 502 is the frame picture data that cuts away behind the white space.So, if directly export corresponding frame picture with the initial coordinate of this role's variable, then can produce position deviation, the size of deviation is this frame picture and carries out frame picture upper left side side-play amount after the cutting of white space when cutting gained, specifically as shown in Figure 6, wherein, dash area is the upper left side side-play amount.Partial picture among Fig. 6 is amplified, obtain picture as shown in Figure 7, Fig. 7 and Fig. 3 are contrasted as can be known, this moment, this role's variable departed from initial position.Therefore, entrained upper left side side-play amount is calculated the actual coordinate of this frame picture in need the frame picture data according to the initial coordinate of this role's variable and this role's variable.
Concrete, the actual coordinate that calculates this frame picture is:
objroleView.rXa＝objroleView.rX+objframe.fx；
objroleView.rYa＝objroleView.rY+objframe.fy；
Wherein, objroleView is this role's variable; ObjroleView.rX and objroleView.rY are respectively the initial horizontal coordinate and the ordinate of this role's variable; The upper left side side-play amount of the horizontal ordinate of gained when the frame picture that objframe.fx and objframe.fy are respectively this role's variable carries out the white space cutting; ObjroleView.rXa and objroleView.rYa are the actual coordinate of this role's variable.
Concrete, the video data of replacing the frame picture is: replace current display frame picture data with the frame picture data of next frame to be played, carry out the frame picture at the actual coordinate place of this role's variable and show, that is:
objroleView.data＝objframe.frame。
Wherein, objframe.frame is the frame picture data of next frame to be played, and this frame picture data is that the frame picture data that is obtained in the step 502 is the data of frame picture itself.
When storage, cut by white space the frame picture, obtain cutting back frame picture data, thereby reduce taking of internal memory; When showing, by calculating the actual coordinate of role's variable, reduce this role's variable initial position, thereby show this frame picture exactly; And because the display area of frame picture diminishes, reduced the calculation consumption that this frame picture is fused to painting canvas.
The embodiment of the invention is revised the position of role's variable in painting canvas by obtain the actual coordinate of frame picture when playing, and the memory headroom that has taken when not only having saved the storage of frame picture has reduced the calculation consumption that is fused to painting canvas when the frame picture shows simultaneously.
