Usage of BigPix

面麻

Problem: I tried to make pix of a line as a whole, but no words showed when previewing avs script.
Is it the reason that I made wrong with the usage of gloabl variable?
Or the misunderstanding of BigPix structure, especially the InitBigPix() function?

Codes listed below:

1. from tcaxPy import *
   
2. 
   
3. 
   
4. def tcaxPy_Init():
   
5.     global font
   
6.     global font_out
   
7.     global font_size
   
8.     font_file   = GetVal(val_FontFileName)
   
9.     face_id     = GetVal(val_FaceID)
   
10.     font_size   = GetVal(val_FontSize)
    
11.     spacing     = GetVal(val_Spacing)
    
12.     space_scale = GetVal(val_SpaceScale)
    
13.     color       = DecRGB(GetVal(val_1C))
    
14.     bord        = GetVal(val_Bord)
    
15.     font = InitFont(font_file, face_id, font_size, spacing, space_scale, color, bord, 0)
    
16.     font_out = InitFont(font_file, face_id, font_size, spacing, space_scale, color, 3 * bord, 1)
    
17. 
    
18. 
    
19. def tcaxPy_User():
    
20.     pass
    
21. 
    
22. 
    
23. def tcaxPy_Fin():
    
24.     FinFont(font)
    
25.     FinFont(font_out)
    
26. 
    
27. 
    
28. def tcaxPy_Main(_i, _j, _n, _start, _end, _elapk, _k, _x, _y, _a, _txt):
    
29. 
    
30.     #ASS_BUF  = []        # used for saving ASS FX lines
    
31.     TCAS_BUF = []        # used for saving TCAS FX raw data
    
32. 
    
33.     # an5 -> an7, TCAS uses an7
    
34.     ux = _x - int(_a / 2 + 0.5)
    
35.     uy = _y - int(font_size / 2 + 0.5)
    
36. 
    
37.     if _j == 0:
    
38.         global LINEPIX
    
39.         LINEPIX = InitBigPix()
    
40. 
    
41.     texture = ImagePix('x3.png')
    
42.     PIX = TextPix(font, _txt)
    
43.     PIX = PixTexture(PIX, texture)
    
44.     BORD = TextPix(font_out, _txt)
    
45.     BORD = PixColorRGB(BORD, 0xFF0000)
    
46.     BORD = PixBlur(BORD, 4)
    
47. 
    
48.     PIX = CombinePixs(BORD, PIX)
    
49.     BigPixAdd(LINEPIX, PIX, ux, uy, 0)
    
50. 
    
51.     if _j == _n - 1:
    
52.         ALINEPIX = ConvertBigPix(LINEPIX)
    
53.         #tcaxLog(ALINEPIX)
    
54. 
    
55.         ts = 10 * _start
    
56.         te = 10 * _end
    
57. 
    
58.         tcas_main(TCAS_BUF, ALINEPIX, ts, te, ux, uy, 0)
    
59. 
    
60.     return (None, TCAS_BUF)

It's pretty grateful of you to offer me these references.
After learning about basic conception of tcas, it seems that creating a line effect has become more difficult than syllable effects, such as line clip.
Maybe it's because of my lack of knowledge about tcas. (Ignore this //
