Hello
I am trying to use the where function on a numpy array which was obtained
from an image using the asarray function. The code is as follows:
from numpy import *
from Image import *
im=open("a.gif")
im2=im.convert("RGBA")
a2 = asarray(im2,uint8)
c = zeros((140,90,4),uint8)
c[:,:]

Hello
Apologies for the incorrect posting before.

instead was using a scalar.

Hello
I have a numpy array that I obtained from a converted RGBA gif image. I have
tried to replace some colours with different ones using the where condition
but have a problem with dimensions.
If I use b=where(a==0,255,a) where a is a numpy array from an image it does
replace components of the
Hello
I am familiar with the fromarray function in the pil library Image module to
plot pixels. Is it possible to do the same for drawtext for text or paste
for images without looping with lists?
Thanks

Hello
I would like to know whether I can do the following in some other way as
this fails with setting an array with a sequence on each of the colour
arrays:
h,w=720,410
img = ones((h,w,3), uint8)*255
img[ngridn,ngride]=(ncolour[0],ncolour[1],ncolour[2])
pilImage = Image.fromarray(img, '
