Python Script to Get RGB Values out of an Image

from PIL import Image

 

# Open our image

im = Image.open("landscape.jpg")

 

# Convert our image to RGB

rgb_im = im.convert('RGB')

 

# Use the .size object to retrieve a tuple contain (width,height) of the image

# and assign them to width and height variables

width = rgb_im.size[0]

height = rgb_im.size[1]

 

# set some counters for current row and column and total pixels

row = 1

col = 1

pix = 0

 

# create an empty output row

rowdata = ""

 

# loop through each pixel in each row outputting RGB value as we go...

# all the plus and minus ones are to deal with the .getpixel class being

# zero indexed and we want the output to start at pixel 1,1 not 0,0!

while row < height + 1:

    print("")

    print("Row number: " + str(row))

    while col < width + 1:

        # get the RGB values from the current pixel

        r, g, b = rgb_im.getpixel((col - 1, row - 1))

        # append the RGB values to the rowdata variable as (R, G, B)

        rowdata += "(" + str(r) + "," + str(g) + "," + str(b) + ") "

        # increment the column count

        col = col + 1

        # increment the pixel count

        pix = pix + 1

    # print out all RGB values for the row

    print(rowdata)

    # clear out rowdata variable

    rowdata = ""

    # increment the row...

    row = row + 1

    # reset the column count

    col = 1

 

# output for proof!

print("")

print("Width = " + str(width) + " pixels")

print("Height = " + str(height) + " pixels")

print("Total Pixels = " + str(pix) + ".")
