PixTexture color!

Alex

I have another 2 question

Why the position it's not exactly correct, there is space between letters?

---

and my second question, if the line(text) position in Aegisub is alignment 7 or 9
when i'm using this postion >>

1.         dx = _x - int(_a / 2 + 0.5)        
   
2.         dy = _y - int(_Fs / 2 + 0.5)      

复制代码

the line (text) it will be in the center of video (an8), what is the right position for alignment7 and 9?

Alex

Thank you very much
it's ok now

OK

I don't know actually which function have to write first..

check it out on this documentation http://www.tcax.org/docs/tcaxLib/namespacemembers_func.html

PIX is a Python structure (object), and can be passed through Pix.... functions, http://www.tcax.org/forum.php?mod=viewthread&tid=220   (unfortunately, this doc is written in Chinese)

We have several ways to create a PIX object, such as TextPix, (create a PIX from text with specified font), BlankPix (a blank square), and pmgToPix (created a PIX from magick image object).

other functions are to manipulate the PIX object, such as PixBlur, PixTexture.


so, when applying the second approach,

PIX_out = PixTexture(PIX_out, PIX_tex2)

can be

PIX_out = PixTexture(PIX_out, PixCrop(PIX_tex2, 0, 0, PIX_out[1][0], PIX_out[1][1]))

the four parameters can be chose by your decision

OK

I don't know actually which function have to write first..

this is the code

1.     PIX_t = TextPix(Font, _txt)            
   
2.    
   
3.     dx = _x - int(_a / 2 + 0.5) + PIX_t[0][0]
   
4.     dy = _y - int(_Fs / 2 + 0.5) + PIX_t[0][1]
   
5.     dur = _KT * 10
   
6. 
   
7.     PIX_t = PixTexture(PIX_t, PIX_tex)     
   
8.     PIX_out = TextPix(FontOut, _txt)      
   
9.     PIX_out = PixTexture(PIX_out, PIX_tex2)
   
10.     PIX_out = PixColorMul(PIX_out, 1, 1, 1, 0)   
    
11.     PIX_out = PixBlur(PIX_out, 0)           
    
12.     PIX_ori = CombinePixs(PIX_out, PIX_t)   
    
13.     points = PixPoints(PIX_ori)
    
14.     pt_num = len(points)

复制代码

and as you said i have to use PixEnlarge(PIX,x,y) function and  PixCrop(pix, left, top, right, bottom)

pix = it will be the path on pic right?
x & y is a normal position (_x,_y) or pixs position
pixx = _x - int(_a / 2 + 0.5) + PIX_t[0][0]
pixy = _y - int(_Fs / 2 + 0.5) + PIX_t[0][1])

?

and regarding PixCrop function , pix I think is a path of pic right?!
and what should Instead of (left, top, right, bottom) write?

The problem is because in PixTexture() function, the size of PIX_tex will be resampled to meet the PIX_txt, so, if the size of text PIX varies, the looks of PIX_texture will be different.

how to resolve the issue,
immediately, we've got two ways
1. enlarge PIX_txt (by invoking PixEnlarge() function) to meet the size of PIX_txt
2. create a PIX_tex for each PIX_txt, according to the size of PIX_txt (using PixCrop() function to cut a piece from the original PIX_tex and make a new one, then pass it to PixTexture() function)
