Step 2, step one is adjusted highly after n raw video image splice in a row, formed and there is n window
Banding video image region, the total length of banding video image regionThe corresponding adjustment of each window
Raw video image after highly；
Step 3, all raw video images can be accommodated with display screen and area is principle to the maximum to banding video figure
Size as region is adjusted：
3.1st, introduce original zoom factor s,
3.2nd, obtain banding video image region close to desired high heWith long le：
he=H × s=(H2×L)/(a×b)
le=L × s=(L2×H)/(a×b)
3.3rd, calculate the final zoom factor r and final high h of banding video image region and long l

Step 4, acquisition banding video image region are distributed to required line number on display screen or columns k：
Wherein
Ku rounds up for kr；Kd rounds downwards for kr；H=he* r, l=le*r；
Step 5, banding video image region is pressed single window be unit, from one jiao of display screen start line by line or
Banding video image area after being sized by column arranges on the display screen, if current line or when prostatitis is booked, arranges
To next line or next column, till will be drained for all video images；If often row or each column have space not take, arrange between two parties
Cloth or left-justify arrangement or Right Aligns arrangement goods dispersion arrangement placed in the middle；If last column or last string drained more than remaining
Video image, then be arranged in the most a row or column in space by unnecessary video image in order, if space is not, will
This unnecessary video figure and current line or reduce together with each video image in prostatitis, until this this unnecessary video figure can be with
Current line or when each video image in prostatitis is arranged in current line together or works as prostatitis；So circulate, until all unnecessary
Video image is all arranged on the display screen；
As k=ku=2,5 video images are shown in Figure 4 in the arrangement effect of display screen；As k=kd=2,
5 video images are shown in Figure 5 in the arrangement effect of display screen；As k=ku=4,5 video images are in display screen
Arrangement effect shown in Figure 6；

Show；As k=ku=3,5 video images are shown in Figure 9 in the arrangement effect of display screen.
Concrete mode is：
The width remembering the i-th row is width [i], highly for height [i], finds minimum a line width [min] of width.
Hi=hi*width [min]/width [i], wi=wi*width [min]/width are zoomed in and out to each video of every a line
[i].Make that the every line width obtaining is roughly the same (because pixel can only be integer, to have the long-pending of decimal point tolerance after scaling
Tired, the always truncation of calculated decimal place, after can have adjustment again, be temporarily considered as every line width equal).
Now the height of the i-th row is height [i]=height [i] * width [min]/width [i].Overall height
HEIGHT
Process through this and obtain an a height of HEIGHT, the rectangle of a width of width [min], a height of a of display, a width of
b.Introduce a coefficient j, make an opposite side of this rectangle get close to the opposite side of display.
Each video height hi=hi*j, each video width wi=wi*j.
Every line height is height [i]=height [i] * j, and every line width is width [i]=width [i] * j.
Due to scaling the impact of the decimal point tolerance bringing, now every line width is not identical, but difference very little, with
That behavior wide is accurate, and the gap of remaining several row and that row the widest is divided in each video being expert at, the length that this operation brings
Wide more very little than impact, negligible.But every line width is all consistent, more aesthetically pleasing.Last center ofthe, occupies up and down
In.
Described above is the situation (as PC or television set) that display is transverse screen, if portrait layout (as mobile phone), both may be used
To realize banding video area by rows by identical algorithm；Transposition can also come, arrange in the way of row, now banding
Video area is to be spliced in the way of commensurateiy wide, and its algorithm thinking is similar to.
