How to import image file as 2D array of RGB values using Python?

[HJ23]

Pseudocode: (thanks Fourier)

Image image = //import your image here, it is 2D array of RGB(A) values

int width = image.width;
int height = image.height;

Node[][] graph = new Node[width][height];

//read image data
for(var x = 0; x < width; x++)
for(var y = 0; y < height; y++){


    //and so on
   if(image[x][y].rgb == Color.roadColor) {

     graph.type == Type.Road;
   } else //...


}

So how do I go about turning this to actual Python code? How to import image as array of RGB colors? How to "image.width", "image.height", "image[x][y].rgb"?

i had a bunch of code here but then i was confused as to what your final goal is.

why do you want an array of rgb colours? you're aware said array would be pixel data (and not very clean).

i mean you can easily import an image with something like

import Image

im = Image.open(path) 

if you have the python imaging library

getting the height and width is then as simple as

width = im.size[0]
height = im.size[1]

I need pixel data.

okay, to clarify, when you import an image with PIL you convert it to pixel data with im.load()

then you browse it with

for x in range (im.size[0]):
	for y in range (im.size[1]):
		i = im.load()

and then you just use i[x,y] to browse the pixel data (which is preset to be in RGB format) so you can just do something like

if i[23,523]<(255,255,255):
print ("not white")

python is very different to c++ as well, and your pseudocode looks like c++

Thanks.
How do I reconstruct array back into image file?

[lintz]

if you edit the pixel data, it's instantly changed on the image file itself so there's no real need to convert the array.

I'm just going out on a limb here but maybe, just possibly, it could be im.save(filename)

Try reading the PIL documentation

If I were you though, I would use opencv instead of PIL.
