oops... forgot a little thing: after the string.split(), you need to convert the
string values to integers before doing the array.
########
import string, Image, array
file = open(filename, 'r')
text = file.readlines()
file.close()
text = string.split(text) #defaults to splitting on any white space, returning a list
for i in range (len(text)): #this is the addition, sorry!
text[i] = string.atoi(text[i])
data = array.array('B', text).tostring()
datasize = (320,240)
im = Image.fromstring('L', datasize, data)
im.save(yourfilename, "TIF")

How about something simpler...

Hi,
I have just started today having a look to PIL, I need to display an image
composed by a matrix of greyscale values saved to a file. The file
contains one line for each image pixel row and separates each pixel's
greyscale value by an space.
I have been trying for a while to modify the example Scripts/viewer.py to
create a new image using method Image.fromstring. However, I haven't had
much success yet. I know it must have been a very silly and simple mistake
but I can not see it. What I do is the following:
imageFile = open(filename)
data = array.array("i")
for iRow in range(240):
dataLine = imageFile.readline()
for iCol in range(320):
iPos = string.find(dataLine, " ")
data.append(int(dataLine[:iPos]))
dataLine = dataLine[iPos+1:]
im = Image.fromstring("L", (320,240), data )
imageFile.close()
UI(root, im).pack()
root.mainloop()
If anybody could point out what I have done wrong I would be very
grateful.
Regards,
Diego
