Get pixel s RGB using PIL

Question

Is it possible to get the RGB color of a pixel using PIL  I m using this code   im   Image open  image gif   pix   im load   print pix 1 1     However  it only outputs a number  e g  0 or 1  and not three numbers  e g  60 60 60 for R G B   I guess I m not understanding something about the function  I d love some explanation   Thanks a lot

Yes  this way   im   Image open  image gif   rgb im   im convert  RGB   r  g  b   rgb im getpixel  1  1    print r  g  b   65  100  137    The reason you were getting a single value before with pix 1  1  is because GIF pixels refer to one of the 256 values in the GIF color palette   See also this SO post  Python and PIL pixel values different for GIF and JPEG and this PIL Reference page  contains more information on the convert   function   By the way  your code would work just fine for  jpg images

Not PIL  but imageio imread might still be interesting   import imageio im   scipy misc imread  um 000000 png   flatten False  mode  RGB   im   imageio imread  Figure 1 png   pilmode  RGB   print im shape    gives   480  640  3    so it is  height  width  channels   So the pixel at position  x  y  is  color   tuple im y  x   r  g  b   color   Outdated  scipy misc imread is deprecated in SciPy 1 0 0  thanks for the reminder  fbahr

GIFs store colors as one of x number of possible colors in a palette  Read about the gif limited color palette  So PIL is giving you the palette index  rather than the color information of that palette color   Edit  Removed link to a blog post solution that had a typo  Other answers do the same thing without the typo

An alternative to converting the image is to create an RGB index from the palette   from PIL import Image  def chunk seq  size  groupByList True          Returns list of lists tuples broken up by size input        func   tuple     if groupByList          func   list     return  func seq i i   size   for i in range 0  len seq   size     def getPaletteInRgb img               Returns list of RGB tuples found in the image palette      type img  Image Image      rtype  list tuple              assert img mode     P    image should be palette mode      pal   img getpalette       colors   chunk pal  3  False      return colors    Usage im   Image open  image gif   pal   getPalletteInRgb im
