# Access pixels on image

We have already learned how to make a pure color image using pixels and change a pixel on the image. Now, we will learn how to identify pixels in existing images.

## Get image data

# Remember to import Image
from PIL import Image
Image.size
Image.size[0]
Image.size[1]


Image.size gives a (width, height) value of an image. Image.size[0] gives the width of the image and Image.size[1] gives the height of the image.

## Let’s see an example

# Remember to import Image
from PIL import Image
img=Image.new('RGB', (200,100),(100,100,100))
# Let's print out the image details:
print(img.size)
print(img.size[0])
print(img.size[1])


The above code will print out:

(200, 100)
200
100


Here the image size is 200 by 100. The width is 200, the height is 100.

## Get pixel information

img.getpixel(x,y) will get a Color value at a certain position. Position is a (width, height) value of that pixel. Color is the RGB Color of that pixel.

## Let’s see an example

# Remember to import Image
from PIL import Image
img=Image.new('RGB', (200,100),"yellow")
color=img.getpixel((100,50))
# Let's print out the pixel color
print(color)


The above code will print out:

(255, 255, 0)


## Get RGB value of a pixel

Each RGB color gives a tuple value (red, green, blue) of a pixel. Color[0] gives the red value of the pixel, Color[1] gives the green value of the pixel, and Color[2] gives the blue value of the pixel.

#### Let’s see an example

# Remember to import Image
from PIL import Image
img=Image.new('RGB', (200,100),"yellow")
color=img.getpixel((100,50))

# Let's print out the RGB value of a pixel
print(color[0])
print(color[1])
print(color[2])


The above code will print out:

255
255
0


Here the RGB value breaks down so that red has a value of 255, green has a value of 255, and blue has a value of 0.
