I want to convert Image file to Bytearray. I extracted image from pdf file with minecart lib, but I cant find a way to convert it to bytearray. This is my code:
import minecart
from PIL import Image
import io
pdffile = open('sample6.pdf', 'rb')
doc = minecart.Document(pdffile)
for page in doc.iter_pages():
print(page)
img = page.images[0].as_pil()
print(img) # <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1641x2320 at 0x7FBDF02E6A00>
print(type(img)) # <class 'PIL.JpegImagePlugin.JpegImageFile'>
I have tried to use bytearray(img)
but It does not work.
Do you have solution for this (solution that does not consume to much time)?

Create io.BytesIO
buffer and write to it using PIL.Image.save
. Set appropriate quality and other parameters as per requirement.
import io
from PIL import Image
def convert_pil_image_to_byte_array(img):
img_byte_array = io.BytesIO()
img.save(img_byte_array, format='JPEG', subsampling=0, quality=100)
img_byte_array = img_byte_array.getvalue()
return img_byte_array
