note: In this demo,
in: vector a→=(100,160), b→=(180,160), c→=(180,240), d→=(120,240); x is float, 0≤x≤1.
out:vector v→ = x3*a→ + 3*x2*(1-x)*b→ + 3*x*(1-x)2*c→ + (1-x)3*d→
When variable x change from 0 to 1, vector v→ change accordingly from d→ to a→.

  note1: This demo use Object operation to import extern file "new.gif" and "red_dot.bmp".
We can use biN operation to embed them into evaFile itself, see about load file.

  note2: The difference between BS_DIB(5) and BS_PATTERN(3) is:
BS_DIB use the color of bitmap itself, BS_PATTERN use pen colorRef.
But in BS_PATTERN mode, if the color of bitmap is not pure black or white(ex. rgb=224,224,224 or rgb=0,64,0 ...),
then window will try to dithered color, and the effect maybe not perfect.
So, in BS_PATTERN mode, the color of bitmap should be pure black or white(rgb=0,0,0 or rgb=255,255,255).

The coordinate's unit is twips. In eva, 1 pixel=16 twips.

EvaViewer use brush colorRef to fill this ngon, and ignore pen colorRef.

 EvaViewer use colorRef_0 and the first half(3*k+1) points, to draw the first bezier line;
and the evaViewer use colorRef_1 and the latter half(3*k+1) points, to draw the latter bezier line;
so the remain 2 points in the middle are ignore.
 The above 2 lines have define a bezierGon, which will be gradient_fill by the evaViewer.

 In this example, every point(x,y) in the bezierGon, can be calculate by λ and μ,
where λ and μ are float, 0≤λ≤1, 0≤μ≤1.
 The color of this point is μ*colorRef_0 + (1-μ)*colorRef_1.
 The coordinate of this point(x,y) is:
x =μ* [λ3*x1 + 3*λ2*(1-λ)*x2 + 3*λ*(1-λ)2*x3 + (1-λ)3*x4]
+ (1-μ)* [λ3*x10 + 3*λ2*(1-λ)*x9 + 3*λ*(1-λ)2*x8 + (1-λ)3*x7]
y =μ* [λ3*y1 + 3*λ2*(1-λ)*y2 + 3*λ*(1-λ)2*y3 + (1-λ)3*y4]
+ (1-μ)* [λ3*y10 + 3*λ2*(1-λ)*y9 + 3*λ*(1-λ)2*y8 + (1-λ)3*y7]

 Of cause, if we are accustomed to using vector calculation, then we can..
step 1: set the first  4 vector are: a→1 =(x1,y1), b→2=(x2,y2), c→3=(x3,y3), d→4=(x4,y4);
    and set the latter 4 vector are: e→10=(x1,y10), f→9=(x9,y9), g→8=(x8,y8), h→7=(x7,y7);
step 2: calculate two temporary vectors:
    v→1 = λ3*a→1  + 3*λ2*(1-λ)*b→2 + 3*λ*(1-λ)2*c→3 + (1-λ)3*d→4,
    v→2 = λ3*e→10 + 3*λ2*(1-λ)*f→9 + 3*λ*(1-λ)2*g→8 + (1-λ)3*h→7.
step 3: calculate the coordinate of this point as μ*v→1 + (1-μ)*v→2

 Now, the style of bezier only support 1(bezier_3x0) 4(begin→end) 8(begin←end) 16(bezier_3x1) or 32(ngon),
Don't support 2(close_curve) or 64(center_brush).

  After the evaViewer drew page1, there are 2 ngon in the RAM, the former is ngon_A, the latter is ngon_B.

  After the evaViewer drew ngon_C at page2, there are 3 ngon in the RAM:
the 2nd(from the end)ngonthe 1st(from the end)ngonthe 0th(from the end)ngon
ngon_Angon_Bngon_C itself

  Now, the M member in ngon_C is 2, it means ngon_C is transformed from ngon_A, which is the 2nd(from the end)ngon.

  After the evaViewer drew ngon_D at page2, there are 4 ngon in the RAM:

ngon_Angon_Bngon_Cngon_D itself

  Now, the M member in ngon_D is 2, it means ngon_D is transformed from ngon_B, which is the 2nd(from the end)ngon.

  If we change the ngon squence at page2, set the former is ngon_D, the latter is ngon_C.
So the M member in these ngon must change too. See it as follows.

the E member in ngon_C is 2, it means ngon_C is transformed to a same shape of ngon_A(which is the 2nd ngon from the end), with new tRanslate postion.

then we get Δx=new_x1-x1= -20, and Δy=new_y1-y1= -30,
so "same shape with new postion" means ngon={(x1+Δx=80, y1+Δy=150), (x2+Δx=160, y2+Δy=150), (x3+Δx=160, y3+Δy=230), (x4+Δx=80, y4+Δy=230)}.

  After the evaViewer drew ngon_D at page2, there are 4 ngon in the RAM:
the 3rd(from the end)ngonthe 2nd(from the end)ngonthe 1st(from the end)ngonthe 0th(from the end)ngon
ngon_Angon_Bngon_Cngon_D itself

  Now, the M member in ngon_D is 2, it means ngon_D is transformed from ngon_B, which is the 2nd(from the end)ngon.

  After the evaViewer drew ngon_E at page3, there are 5 ngon in the RAM:
the 4th(from the end)ngonthe 3rd(from the end)ngonthe 2nd(from the end)ngonthe 1st(from the end)ngonthe 0th(from the end)ngon
ngon_Angon_Bngon_Cngon_Dngon_E itself

  Now, the M member in ngon_E is 1, it means ngon_E is transformed from ngon_D,which is the 1st(from the end)ngon.

  After the evaViewer drew ngon_F at page3, there are 6 ngon in the RAM:
the 5th(from the end)ngonthe 4th(from the end)ngonthe 3rd(from the end)ngonthe 2nd(from the end)ngonthe 1st(from the end)ngonthe 0th(from the end)ngon
ngon_Angon_Bngon_Cngon_Dngon_Engon_F itself

  Now, the M member in ngon_F is 3, it means ngon_F is transformed from ngon_C, which is the 3rd(from the end) ngon.
the E member in ngon_F is 5, it means ngon_F is transformed to a same shape of ngon_A(which is the 5th ngon from the end), with new tRanslate postion.
  Because shape of ngon_A={(x1=100,y1=160), (x2=180,y2=160), (x3=180,y3=240), (x4=100,y4=240)},
and new coordinate in ngon_F=(new_x1=80, new_y1=110),
then we get Δx=new_x1-x1= -20, and Δy=new_y1-y1= -50,
so "same shape with new postion" means ngon={(x1+Δx=80, y1+Δy=110), (x2+Δx=160, y2+Δy=110), (x3+Δx=160, y3+Δy=190), (x4+Δx=80, y4+Δy=190)}.

  Now, the M member in keep_Going is 2, it means keep_Going is just keep text_B's going, which is the 2nd(from the end)text.
In the other words, it just said "I am here. I am moving. I am not disappear. EvaViewer, dont forget to show me. About my coordinate, who care..."

the E member in text_E is 3, it means text_E is pan to text_B(which is the 3rd text from the end)

  After the evaViewer read page2, it show "2" for 200 centiSecond. During the period, the evaViewer monitor the tick_count weather it is > 4.5 second. When OK, the evaViewer execute the "jump to sticker" command immediately. So page2 is shown more than half of originally scheduled time.

  3.Page3 is a common polyLine,
page4 is a common triangle.
  Transform from page3 to page4,
is a part of common animation.
  And page3 export a sticker
which name is "1".

  1.1.Page1 import an animation source object, whick sticker name is "1", and the width and height of its datum frame is ws=130-60=70 and hs=230-180=50, and center coordinate of source datum frame is (xcs,ycs)=(95,205).//(130+60)/2, (230+180)/2

  1.2.Above is only for source. In dest page(page 1), the evaViewer calculate the center coordinate (xcd, ycd): xcd=x1+r*cosφ=60+0*cos30°=60, ycd=y1+r*sinφ=180+0*sin30°=180.

  1.3.The affine transformation between source and dest(page1) is:
λ=x*(wd/ws)*cos(φ+θ) + y*(hd/hs)*cos(φ+ψ) = x*(40/70)*cos(30°+0°) + y*(20/50)*cos(30°+90°) = 0.571*x*cos30°- 0.4*y*sin30°
μ=x*(wd/ws)*sin(φ+θ) + y*(hd/hs)*sin(φ+ψ) = x*(40/70)*sin(30°+0°) + y*(20/50)*sin(30°+90°) = 0.571*x*sin30°+ 0.4*y*cos30°

  1.4.Maping every all source page objects' point (xcs+x, ycs+y) to dest page objects' point (xcd+λ, ycd+μ).
That means map every point (95+x,205+y) in page3(NOT only in datum frame, but also in ALL page3) to (60+λ, 180+μ) in page1.
Actually only at the start tick use page3, and when tick=100 centiSecond it use page4.
We can imagine that, in page1 near the center coordinate (x1,y1), we have embed another eva there, and the "another eva" is begin from sticker "1" to end page.

  2.1.Page2 import the same animation source object, too.

  2.2.But center dest coordinate in page2 (xcd, ycd) are change to: xcd=x2+r*cosφ=80+0*cos30°=80, ycd=y2+r*sinφ=80+0*sin30°=80.

  2.3.The affine transformation between source and dest(page2) is:
λ=x*(wd/ws)*cos(φ+θ) + y*(hd/hs)*cos(φ+ψ) = 0.571*x*cos120°- 0.4*y*sin120°
μ=x*(wd/ws)*sin(φ+θ) + y*(hd/hs)*sin(φ+ψ) = 0.571*x*sin120°+ 0.4*y*cos120°

  2.4.Map every point (95+x,205+y) in page3(NOT only in datum frame, but also in ALL page3) to (80+λ, 80+μ) in page2.
Actually only at the start tick use page3, and when tick=100 centiSecond it use page4.
We can imagine that, in page2 near the center coordinate (x2,y2), we have embed another eva there, and the "another eva" is begin from sticker "1" to end page.

  1.5.In page1, behind the "Animation" operation, (the eva file format is)must define a polyLine between (x1,y1) and (x2,y2), to define how to move this obJect. This demo only define a straight line, we can change it.

  2.5.In page2, behind the "Animation" operation, (the eva file format is)must define a polyLine too. This demo only define a straight line which length=0.

  2.6.Now, after show page2, the evaViewer show page3. This demo is too lazy, in the end of page2, it should add a "jump" operation to another page, avoid these discomfiture things.

To be continue...
