Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, it will be appreciated that preferred embodiment described herein, only for instruction and explanation of the present invention, is not intended to limit the present invention.
Fig. 1 is the schema of the cutting method of a kind of video in the embodiment of the present invention. As shown in Figure 1, comprise the following steps:
The block of the arranged of step 101, the capable n row that generate m according to the dimension scale of video, wherein m and n is parameter preset;
The block of step 102, the arranged that described video is arranged as the brush object value in WindowsPresentationFountation user interface frame to the capable n of described m;
Step 103, the block of arranged arranged by the capable n of described m show the content of described video correspondence position respectively.
In the step 101 of the present embodiment, for the video file that any one is being play, generating the block of the arranged of the capable n row of m according to the dimension scale of video, the overall Aspect Ratio after the splicing of these blocks should be identical with original video ratio.
WPF (WindowsPresentationFoundation) is the user interface frame based on WindowsVista that Microsoft releases, and belongs to a part of .NETFramework3.0. It provide unified programming model, language and framework, really accomplish the work of separating interface designer and developer; It provide brand-new multimedia interactive graphical interface of user simultaneously.
In WPF, having the object of a visual paintbrush of VisualBrush, this paintbrush can be used as arbitrary control as a brush to be assigned to other object, a video play, and equally also can be used to the brush as another one control. Brushing in these matrix squares using object video as brush again, each square needs the video brush region regulating display according to current row and column. Each region will show the content of the corresponding position display corresponding with former video like this.
Like this, such as, after the block of the arranged arranged at the capable n of above-mentioned m shows the step of the content corresponding with described video respectively, it is possible to the arbitrary block of the arranged that the capable n of described m arranges is carried out interact, amplifies, reduce or rotate.
Fig. 2 is the schematic diagram of the cutting method of video in the embodiment of the present invention. As shown in Figure 2, it is numbered the relatively original video of square of 1, the brush region got should be a starting point (0,0) the 1/4 of original width Width is accounted for, account for the 1/3. brush scope attribute that can release all squares equally of the Height of original height, 12 squares just can be got the region of corresponding video brush by these attributes, and these fragment regions are stitched together and again form a complete video play. These matrix fragments are independent of one another, so these fragments just can carry out different interacts, it is carried out some multiple point touching programmings, such as No. 6 fragments by us, and under touch-screen environment, we can haul out it come, it is amplified, reduce, rotate and wait operation, other fragment can also be operated simultaneously, mutually not influenced, independently of one another.
For the region of a certain irregular shape of arbitrary video loop graph, the embodiment of the present invention proposes preferred embodiment. Fig. 3 is the schema of the cutting method of another kind of video in the embodiment of the present invention. As shown in Figure 3, comprise the following steps:
A region in the video that step 301, selection are play;
Step 302, the path objects generating position identical with a described region cover on picture region;
Step 303, using video corresponding for described region as the brush object value in WPF (WindowsPresentationFoundation) give described picture region;
Step 304, the content being shown the video of correspondence position by described picture region.
Preferably, also comprise after the step of the content of the video of described picture region display correspondence position: described picture region is carried out interact.
In some cases, it is necessary to certain irregular area in a video is carried out interact, such as, zooms in or out, in the present embodiment, utilize the characteristic of VisualBrush, it is possible to arbitrary video circle is drawn certain region, these regions are taken out and is used as an irrelevant independent individual.The basic ideas obtaining this circle picture region first draw the region wanted, then the path objects Path generating an identical position covers on the region of circle picture, the filling brush of this Path is arranged to the video play, and a certain of the broadcasting video that this circle picture region just can be independent so partly irregular.
Therefore in the present embodiment, the step in a region in the video play is selected to comprise: to utilize InkCanvas ink drawing board control to perform paintbrush loop graph action in WPF; The step that described generation covers on picture region with the path objects of identical position, a described region comprises: all coordinate point relative to video gathering paintbrush loop graph action process, calculate the coordinate point of described path objects according to the coordinate of described coordinate point; The coordinate point of described path objects is plotted on described picture region.
Comprise to the step in described picture region as the brush object value in WPF video corresponding for described region: the interval that described brush object is set according to the position of described path objects and size; Described picture region is given as the brush object value in WPF using described interval corresponding video.
Described in concrete operating process as follows: first utilize InkCanvas control to perform paintbrush circle picture action in WPF, circle paints complete, can collect lines all coordinate point relative to video of process, collecting these points leaves in a set PointCollection, analyze these points, all X-coordinates are found its maximum value XMax and minimum value XMin, all ordinate zous are found its maximum value YMax and minimum value YMin
The width of the Path so needing to generate is (XMax-XMin), it is highly (YMax-YMin), the top left co-ordinate of this Path object in former video is just (XMin, YMin), and such Path just has a correct position and size. PointCollection have collected the coordinate point of person's handwriting relative to source video, need now these points are converted into the coordinate point relative to new Path, this needs the X by all coordinates in PointCollection to subtract XMin, Y subtracts YMin, have and gathered relative to the PointCollection of Path, just can draw the path the same with person's handwriting on Path, it is source video that this Path arranges its filling brush, the brush that the position of foundation Path and size arrange VisualBrush is interval, so just, the unit that an irregular area plays video can be generated, this unit is added multiple point touching programming again, do this irregular area arbitrarily to move and wait multiparty control operation.
VisualBrush and Inkcanvas control in above-described embodiment comprehensive utilization WPF, achieve the collection for arbitrary shaped region in video and video reproduction, can allow its part interested in any selecting video of user, and not limit concrete shape, more be applicable to user and use.
