Error 'module' object has no attribute 'freetype'

问题

I am using this code Link but it displays error of module object has no attribute i tried to pip install freetype but nothing happened. Can anyone please guide me with this.

import cv2
import numpy as np   
img = np.zeros((100, 300, 3), dtype=np.uint8)

ft = cv2.freetype.createFreeType2()
ft.loadFontData(fontFileName='Ubuntu-R.ttf',
                id=0)
ft.putText(img=img,
           text='Quick Fox',
           org=(15, 70),
           fontHeight=60,
           color=(255,  255, 255),
           thickness=-1,
           line_type=cv2.LINE_AA,
           bottomLeftOrigin=True)

cv2.imwrite('image.png', img)

If cv2.freetype does not run in python you can still use freetype-py module.

I have written a wrapper around the PIL library api calls in opencv for python2/3 which can be used in the following way: (download from https://github.com/bunkahle/PILasOPENCV )

from __future__ import print_function
import PILasOPENCV as Image
import PILasOPENCV as ImageDraw
import PILasOPENCV as ImageFont
import cv2

font = ImageFont.truetype("arial.ttf", 30)
print(font)
im = Image.new("RGB", (512, 512), "grey")
draw = ImageDraw.Draw(im)
text = "Some text in arial"
draw.text((100, 250), text, font=font, fill=(0, 0, 0))
print(ImageFont.getsize(text, font))
mask = ImageFont.getmask(text, font)
print(type(mask))
cv2.imshow("mask", mask)
im.show()
im_numpy = im.getim()
print(type(im_numpy), im_numpy.shape, im_numpy.dtype)

It uses the freetype-py module in the background. PILasOPENCV is actually a project for migrating old PIL projects to OPENCV. Install with

setup.py install

pip install PILasOPENCV

More details and test can be found in github.

install harfbuzz and freetype follow this link
build opencv-contrib follow this link and this link
Put a symlink to the bindings in your local site-packages:

ln -s /usr/local/lib/python3.5/site-packages/cv2.cpython-35m-x86_64-linux-gnu.so $HOME/.pyenv/versions/3.5.2/lib/python3.5/site-packages/

You're just missing opencv-contrib, you can install that with pip install opencv-contrib-python.
