I think you're supposed to use the point method, but I don't have

im.mode gives you a string such as 'RGBA' or 'CMYK'. im.getbands()
returns a tuple such as ('R', 'G', 'B

For example for png picture format
im.getpixel((20,50)) gives the result 60.
What does the value mean?
Is it possible to find out the RGB model

Hi;
I´ve installed Zope 2.10.5 on top of Python 2.4.2 (not optimal, but it will
work, according to the build instructions). I installed Plone 3.0.2 and I get
errors when I crank up Zope, all related to a non-existent PIL. So I d/l/d the
latest PIL, plopped it in my Extensions dir, ran
i am trying to get the pixel data using im.getpixel()
i am getting a tuple like (152,118,106) for a pixel in a RGB jpeg
image .
what i really want is an integer value representing a pixel ,like waht
i can get from java's BufferedImage.getRGB(x,y) ..
i am wondering if someone can advise me on how

Just pack the RGB values into an `int` by shifting and or-ing. Untested:
red, green, blue = img.getpixel(x, y)
pixel_as_int = red 16 | green 8 | blue
Ciao,
Marc 'BlackJack' Rintsch
thanx Marc
will try that

Hi..
I find the picture color with:
im=Image.open(/%s %name)
of
that?
are there anybody who know that
Who knows what? That PIL has e.g. a histogram-function that delivers what
you need (after some thinking, I suggest you try and see at it's output
with various source images)
