PIL, and Parts of tuples
I have two problems, and I can't find anything about either of them. The first is that PIL does not seem to have any way to search each and every pixel for a value, like for pixel in img: if pixel = ((60, 30), (58, 23), (87 57)): # Get out of the for loop # Also, save the pixel quardinates to a variable Then, I also want it to look at a specific pixel (I've got that down), and do something if the any one of the values in the tuple is out of range. The issue is, the range is different for every value. Basically, it is to see if the pixel is in an acceptable color range. So, say, the 60 above can be anywhere from 58-62, but the 30 needs to be between 28-40. Is there any way to parse/deal with a value at a specific slot in a tuple? -- http://mail.python.org/mailman/listinfo/python-list

Yes, use subscripting, just like with lists: the_tuple = (60, 30)#for example if not (58 = the_tuple[0] = 62) or not (28 = the_tuple[1] = 40): #it's out of range, do something Cheers, Chris -- I have a blog: http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
Re: PIL, and Parts of tuples
Actually, I screwed up. See 60, 30? That's actually the range. The tuple to be checked will look like (40, 25, 51) So yeah. Sorry for the bad info. For a good time, go to Start:Run and type in format Chttp://www.vistro.net/ On Mon, Apr 13, 2009 at 3:41 PM, Chris Rebert c...@rebertia.com wrote: On Mon, Apr 13, 2009 at 1:34 PM, Vistro vis...@vistro.net wrote: I have two problems, and I can't find anything about either of them.
