How to fix if-elif-else syntax error?

[sbtunx]

hi
the problem is a syntax error that highlights pink the "elif" in the program just that. this code is to water mark picture "test.jpg" with the water mark of "model.jpg" with a mark on a white background the cod is:

import Image,math
model = Image.open("model.jpg")
test = Image.open("test.jpg")
x=test.size[0]
y=test.size[1]
im  = Image.new("RGB",(x,y))
 
for i in range(300):
 for j in range(300):
 
  rpixel,gpixel,bpixel=test.getpixel((i,j))
  rmodel,gmodel,bmodel=model.getpixel((i,j))
 
  if 255==rmodel and 255==gmodel and 255==bmodel:
   im.putpixel((i,j),(rpixel,gpixel,bpixel)
  elif rmodel!=255 or gmodel!=255 or bmodel!=255:
   rrr=int((1.2*rpixel-45))
   ggg=int((1.2*gpixel-45))
   bbb=int((1.2*bpixel-45))
   im.putpixel((i,j),(rrr,ggg,bbb)     
 
im.save('end.bmp')
im.show()

That error often indicates a missing closing parenthesis. A missing closing parenthesis is causing your error.

lines 15 and 20 need closing parentheses.
