This is the code(a simple python code which could add a number to a picture):
from PIL import Image, ImageDraw, ImageFont
def addnum(number, filepath):
img = Image.open(filepath)
width, height = img.size
draw = ImageDraw.Draw(img)
front_size = height/4
ttf_front = ImageFont.truetype('Arial.ttf', front_size)
draw.text((width - front_size, 0), number, (255, 0, 0), font = ttf_front)
del draw
img.save('wechat_addnum.jpg')
img.show()
if __name__ == '__main__':
addnum('4','wechat.jpg')

I don't know the real problem, and from the google and other questions from stackoverflow I cannot find the method which could solve this problem.
Thank you!!
This is a know issue. Try to update Pillow using pip install Pillow --upgrade

I have some code that is supposed to open a font in multiple sizes:
from PIL import ImageFont
INTER_BOLD_48 = ImageFont.truetype("assets/Inter-Bold.ttf", 48)
INTER_BOLD_36 = ImageFont.truetype("assets/Inter-Bold.tff", 36)
INTER_BOLD_28 = ImageFont.truetype("assets/Inter-Bold.tff", 28)
# more fonts get opened below, but it never makes it there
However, this throws the error OSError: cannot open resource
Full error:
File "/home/lazza/PycharmProjects/YippyBot/tests.py", line 4, in <module>
INTER_BOLD_36 = ImageFont.truetype("assets/Inter-Bold.tff", 36)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 1008, in truetype
return freetype(font)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 1005, in freetype
return FreeTypeFont(font, size, index, encoding, layout_engine)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 255, in __init__
self.font = core.getfont(
OSError: cannot open resource
From the error I realised that the first font opening was running fine.
So I tried changing the font size in the argument to see if setting it to 36 was the problem:
from PIL import ImageFont
INTER_BOLD_48 = ImageFont.truetype("assets/Inter-Bold.ttf", 36)
INTER_BOLD_36 = ImageFont.truetype("assets/Inter-Bold.tff", 36)
INTER_BOLD_28 = ImageFont.truetype("assets/Inter-Bold.tff", 28)
But the error is exactly the same:
Traceback (most recent call last):
File "/home/lazza/PycharmProjects/YippyBot/tests.py", line 4, in <module>
INTER_BOLD_36 = ImageFont.truetype("assets/Inter-Bold.tff", 36)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 1008, in truetype
return freetype(font)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 1005, in freetype
return FreeTypeFont(font, size, index, encoding, layout_engine)
File "/home/lazza/PycharmProjects/YippyBot/venv/lib/python3.10/site-packages/PIL/ImageFont.py", line 255, in __init__
self.font = core.getfont(
OSError: cannot open resource
So I figured maybe opening the same font twice was causing the problem and so commented the first line out:
# INTER_BOLD_48 = ImageFont.truetype("assets/Inter-Bold.ttf", 48)
INTER_BOLD_36 = ImageFont.truetype("assets/Inter-Bold.tff", 36)
Same error. I also tried duplicating the .ttf files and giving each font a unique name, as well as giving the full path to the font.
I am on Linux, but I don't see why that would be a problem as I provide the path to the font.
I am doing a small script to paste an image into a black background to have same size images for a dataset. Here is the script:
for file in glob.glob(imagetteDir):
r = str(file)
image = Image.open(file)
img = np.zeros([100,100,3],dtype=np.uint8)
imageio.imwrite('black.tif', img)
black = Image.open('black.tif')
position = ((black.width - image.width), (black.height - image.height))
print(position)
Image.Image.paste(black,image,position)
dirr , name = r.split("imagette")
path1 = name.raplace("Hexagone_resized","Hexagone")
print(path1)
black.save(imagetteresizeDir+path1)
So Image.Image.paste() make the following error that i didnt find how to resolve:
Traceback (most recent call last):
File "C:\Users\user\Documents\Project\segmentation\Imagette creation\resizing.py", line 29, in <module>
Image.Image.paste(black,image)

return self._load_libtiff()
File "C:\Users\user\Anaconda3\envs\tf_gpu\lib\site-packages\PIL\TiffImagePlugin.py", line 1182, in _load_libtiff
raise OSError(err)
OSError: -2
Have you any idea from where it might come?
Thanks in advance for your help
I am trying to extract text from a gif image using the below code, it has worked for png format not working for gif.
import pytesseract
import io
import requests
from PIL import Image
url = requests.get('http://article.sapub.org/email/10.5923.j.aac.20190902.01.gif')
img = Image.open(io.BytesIO(url.content))
text = pytesseract.image_to_string(img)
print(text)
getting this error

The idea is to convert each of the frames to RGB image before performing the OCR on them, as shown below -
for frame in range(0,img.n_frames):
img.seek(frame)
imgrgb = img.convert('RGBA')
imgrgb.show()
text = pytesseract.image_to_string(imgrgb)
print(text)

i amusing PIL to write some text inside and an image and then saving it at the same location. Following is my function which does this
from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw
def add_text_to_image(image_path):
img = Image.open(image_path)
img = img.convert('RGB')
widht, height = img.size
draw = ImageDraw.Draw(img)
font = ImageFont.truetype("helvetica.ttf", 20)
draw.text((0, 0), "Some text", (0, 0, 0), font=font)
img.save(image_path)
But i am getting following error.

i have tried some solution from internet but nothing is working and i don't know what i am doing wrong here. any help is appreciated
I've looked around and could not find anything regarding this. The issue is probably due to me being somewhat new to Python and I was hoping I could get some help here.
I came across this blog post from 2009: http://stacksmash.org/2009/09/packet-visualization-with-python/
However when I run this, I get the following error in line 1129 of Scapy's packet.py
$ python test-image.py
Traceback (most recent call last):
File "test-image.py", line 9, in <module>
if(len(pkt.load) > imgWidth):

Is this maybe an issue with newer library versions (considering this is a blogpost from 2009) or am I missing something here?
This works for me with Python 3.6.4:
from PIL import Image
from scapy.all import rdpcap
capture = rdpcap('./capture.pcap')
imgHeight = len(capture)
imgWidth = max(len(packet) for packet in capture)
imgSize = imgWidth, imgHeight
print('Image Size: ', imgSize)
img = Image.new('RGB', imgSize, (255, 255, 255))
for i in range(0, imgHeight):
for j in range(0, len(capture[i])):
color = ord(str(capture[i])[j])
# print('Writing pixel', (j,i), 'with value:', color)
img.im.putpixel((j,i), (0, color, 0))
img.save('./result.png')
