"SystemError: tile cannot extend outside image" in PIL during save image
Solution 1
With reference to the comments, the error occurred due to improper passing of the coordinates to PIL's crop()
function.
As mentioned in the documentation, the function returns an image having taken in a tuple of four (x
, y
, width
and height
).
In the given text file the y
coordinate is mentioned in the first column and x
coordinate in the second column. The crop()
function however accepts the value of x
coordinate as the first parameter and the y
coordinate as the second parameter.
The same applies for OpenCV as well
Here is ANOTHER POST regarding the same.
Solution 2
The mentioned way on the internet is like this:
imageScreenshot.crop((x, y, width, height))
But the correct way is this:
imageScreenshot.crop((x, y, x + width, y + height))
Meaning that you should add the x
to the width
and y
to the height
.
This is a simple example (driver
is for python selenium):
def screenShotPart(x, y, width, height) -> str:
screenshotBytes = driver.get_screenshot_as_png()
imageScreenshot = Image.open(BytesIO(screenshotBytes))
imageScreenshot = imageScreenshot.crop((x, y, x + width, y + height))
imagePath = pathPrefix + "_____temp_" + str(time.time()).replace(".", "") + ".png"
imageScreenshot.save(imagePath)
Hope it helps.
Solution 3
In my case the issue was that I was specifying start and end coordinates where the start X and start Y were not always less than the end X and Y. You cannot do this.
For example,
Start: (0, 50) End: (50, 0)
These coordinates make sense to me, but should actually be specified as:
Start: (0, 0) End: (50, 50)
Visually the same rectangle, but the latter is required for Pillow to crop.

I have this Image =>
here is, all coordinates of above yellow boxes that is written in
3.txt
file.#Y X Height Width 46 135 158 118 46 281 163 104 67 494 188 83 70 372 194 101 94 591 207 98 252 132 238 123 267 278 189 105 320 741 69 141 322 494 300 135 323 389 390 124 380 726 299 157 392 621 299 108 449 312 227 93 481 161 425 150 678 627 285 91 884 13 650 437 978 731 567 158 983 692 60 43 1402 13 157 114
My intension is to crop those boxes and save all boxes as Image. I have written a code for that but getting error.
Here is my code =>
from PIL import Image import matplotlib.pyplot as plt import numpy as np from os import listdir #from scipy.misc import imsave ARR = np.empty([1,4]) # print(ARR) i = 0 k = 0 img = Image.open('3.png') fo = open("3.txt", "r") for line in fo: if not line.startswith('#'): for word in line.split(): ARR[0][i] = int(word) print(int(word)) # ARR[0][i] = int(word) i = i +1 img2 = img.crop((int(ARR[0][1]), int(ARR[0][0]), int(ARR[0][0] + ARR[0][2]), int(ARR[0][1] + ARR[0][3]))) name = "new-img" + str(k) + ".png" img2.save(name) k = k + 1 i = 0
I am getting these error =>
Traceback (most recent call last): File "reshape.py", line 26, in img2.save(name) File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1468, in save save_handler(self, fp, filename) File "/usr/lib/python2.7/dist-packages/PIL/PngImagePlugin.py", line 624, in _save ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, rawmode)]) File "/usr/lib/python2.7/dist-packages/PIL/ImageFile.py", line 462, in _save e.setimage(im.im, b) SystemError: tile cannot extend outside image
How do I fix these?

Max Kuchenkiller over 4 yearsPointing out that for me AmirHosseins answer actually was the correct one. The parameters are
imageScreenshot.crop((x, y, x + width, y + height))
and notimageScreenshot.crop((x, y, width, height))

kmario23 over 2 yearsThe Pillow doc says both are correct, although I found the above answer to be working fine.

Can over 2 yearsI could not see such information in the corresponding document. It says "four coordinates; left, upper, right, lower". It means the function takes four coordinates of the region. Last two parameters are not width and height. Instead, x+width and y+height as explained in the document. Maybe people get consued because of other functions that take (x,y,width,height) (such as ImageDraw.rectangle).
