Hello. I have recently been experimenting with cellular automata and I
would like to know how I could convert a 2d list of 0's and 1's into
white and black squares on an image. I have tried to install matplotlib
and also NumTut but both to no avail. There seem to be bugs in their
installation and I have not been able to figure out how to resolve
them. I would be happy for someone to suggest a library and maybe give
a simple example of how to do what I want to do. 7 2874 de*****@gmail.c om wrote: Hello.

Why don't you explain your problems with installing numpy (the Numeric Tutorial
is out of date; don't bother with NumTut) or matplotlib on the appropriate
mailing lists? http://lists.sourceforge.net/lists/l...mpy-discussion http://lists.sourceforge.net/lists/l...tplotlib-users

I have recently been experimenting with cellular automata and I would like to know how I could convert a 2d list of 0's and 1's into white and black squares on an image. I have tried to install matplotlib and also NumTut but both to no avail. There seem to be bugs in their installation and I have not been able to figure out how to resolve them.

In my 1d cellular automaton, I used the python image library and
import Image
nim = Image.new("1", (height * 2, height))
nim.putdata(bim g)
nim.resize((400 ,200)).save("ou tput.png")
where bimg is a 2d list of 0's and 1's. You could probably remove the
resize.
Thank you very much. That is highly simple, useful and it works.
It seemed to work with a 1d list but not with 2d.
import Image
x = []
buff = []
buff = [[0 for y in range(41)] for x in range(21)]
buff[0][(len(buff)-1)/2] = 1
def rule1():
for i in range(len(buff)-1):
for j in range(len(buff[0])-1):
if i == len(buff)-1:
break
elif j == 0:
if buff[i][j+1] == 1:
buff[i+1][j] = 1
elif j == len(buff[0])-1:
if buff[i][j-1] == 1:
buff[i+1][j] = 1
elif buff[i][j-1] == 1:
buff[i+1][j] = 1
elif buff[i][j+1] == 1:
buff[i+1][j] = 1
def rule2():
for i in range(len(buff)-1):
for j in range(len(buff[0])-1):
if i == len(buff)-1:
break
elif j == 0:
if buff[i][j+1] == 1:
buff[i+1][j] = 1
elif j == len(buff[0])-1:
buff[i+1][j] = 1
elif buff[i][j-1] == 1 and buff[i][j+1] != 1:
buff[i+1][j] = 1
elif buff[i][j+1] == 1 and buff[i][j-1] != 1:
buff[i+1][j] = 1
rule2()
nim = Image.new("1", (400,600))
nim.putdata(buf f)
nim.resize((400 ,600)).save("ou tput.png")
for a in buff:
for x in a:
if x == 1:
print "X",
else: print " ",
print ""
That is my code. Could you tell me what maybe is wrong? Rule2 makes the
fibonacci triangle btw.
Sorry this is the latest, the previous didn't work so well:
import Image
x = []
buff = []
buff = [[0 for y in range(41)] for x in range(21)]
buff[0][(len(buff[0])-1)/2] = 1
def rule1():
for i in range(len(buff)-1):
for j in range(len(buff[0])-1):
if i == len(buff)-1:
break
elif j == 0:
if buff[i][j+1] == 1:
buff[i+1][j] = 1
elif j == len(buff[0])-1:
if buff[i][j-1] == 1:
buff[i+1][j] = 1
elif buff[i][j-1] == 1:
buff[i+1][j] = 1
elif buff[i][j+1] == 1:
buff[i+1][j] = 1
def rule2():
for i in range(len(buff)-1):
for j in range(len(buff[0])-1):
if i == len(buff)-1:
break
elif j == 0:
if buff[i][j+1] == 1:
buff[i+1][j] = 1
elif j == len(buff[0])-1:
buff[i+1][j] = 1
elif buff[i][j-1] == 1 and buff[i][j+1] != 1:
buff[i+1][j] = 1
elif buff[i][j+1] == 1 and buff[i][j-1] != 1:
buff[i+1][j] = 1
elif buff[i][len(buff[0])-1] == 1 or buff[i][0] == 1:
break
rule2()
nim = Image.new("1", (50,50))
nim.putdata(buf f)
nim.resize((400 ,600)).save("ou tput.png")
for a in buff:
for x in a:
if x == 1:
print "X",
elif x == 0: print " ",
print ""
for a in buff:
print a
Actually never mind either. I guessed I needed to append all values
after eachother in one row list:
x = []
for y in buff:
for z in y:
x.append(z)

Hi.
I'm doing some image manipulation in an applet using the example code on
this page:
http://www.akop.org/art/pixels3.htm
However, I really want an application rather than an applet, I just
can't figure out how to do the image loading and manipulation when it's
not from inside an applet. Any hints on the subject are appreciated.

Hi,
I would like to find out what ASP/ASP.net can do with image manipulation.
Does ASP have built in functions (eg. after upload to server) to
manipulate images, like rotate, scale, crop etc.? Or are 3rd party
solutions needed to do this?
I am a php/codfusion programmer and know nothing about asp, so I'm
hoping somebody here can help me out.

I dont know, and i dont much like javascript, however, i am told that
the only way to do want i want to do, is with javascript, so here goes.
zoom and cut is the only features i need.
1. the image that need manipulating is places on the server. dont need
js for that ;-)
2. the client has the oppotunity to manipulate the image. cut and zoom.
3. the image i saved on the server.

Hi there,
I want to show a simple image on a web page, and allow the viewer to
select and change one of the colours used in the image, and immediately
preview the result. I'd like to keep the image processing away from the
server to make the colour selection/preview process quicker, and I also
don't want to pre-generate all possible images as there are too many
colours that can be selected.
Does JS (or any JS libraries) provide image...
