Answer 1

There seems an open bug for rendering the hindi (Devanagari font) text.

https://github.com/python-pillow/Pillow/issues/3191

You may try with some other library like: pyvips (I do not find the API very intuitive, but it may work for you)

import pyvips


# To install 'pyvips' refers to https://pypi.org/project/pyvips/
#  1. Intall libvips shared library from https://jcupitt.github.io/libvips/install.html
#  2. Set the PATH variable.
#  3. run pip install pyvips

def generate_tweet_image():
    cnum = 1
    output_file = "tweet_file.png"
    text = u''
    with open("hindi.txt", "r", encoding='UTF-8') as filestream:
        for l in filestream.readlines():
            text = text + f'{cnum}) {l}'
            cnum += 1

    MAX_W, MAX_H = 1500, 1500

    # See for API https://jcupitt.github.io/pyvips/vimage.html#pyvips.Image.text

    # font file: ARIALUNI.TTF
    image = pyvips.Image.text(text, width=MAX_W, height=MAX_H, font='Arial Unicode MS', dpi=96)
    image.write_to_file(output_file)
    print(f'File Written at : {output_file}')


generate_tweet_image()

Output:

Hope this helps.

Installing Raqm, is the ultimate clean soon,check following steps

One of the following methods can be used for building Raqm:

1. Raqm depends on the following libraries:

FreeType HarfBuzz FriBiDi

To install dependencies on Fedora:

sudo dnf install freetype-devel harfbuzz-devel fribidi-devel gtk-doc

To install dependencies on Ubuntu:

sudo apt-get install libfreetype6-dev libharfbuzz-dev libfribidi-dev \ gtk-doc-tools

On Mac OS X you can use Homebrew:

`export XML_CATALOG_FILES="/usr/local/etc/xml/catalog" # for the docs`

Once you have the source code and the dependencies, you can proceed to build. To do that, run the customary sequence of commands in the source code directory:

To do that, run the customary sequence of commands in the source code directory (configure file is not found in the package, The key was to run autogen.sh before):

$ ./autogen.sh
$ ./configure
$ make
$ make install

To run the tests:

$ make check

sudo ldconfig This step was needed!

Run the following test script: (Make sure the fonts are installed sudo apt install fonts-indic)

from PIL import Image, ImageFont, ImageDraw

im = Image.new("RGB",(160, 160))
draw = ImageDraw.Draw(im)

font_telugu = ImageFont.truetype("/usr/share/fonts/truetype/fonts-telu-extra/Pothana2000.ttf",50)
text_telugu = "నిత్య"

font_hindi = ImageFont.truetype("/usr/share/fonts/truetype/Gargi/Gargi.ttf",50)
text_hindi = "नित्य"

draw.text((10, 10), text_telugu, font=font_telugu)
draw.text((10, 90), text_hindi, font=font_hindi)
im.show()

2. install tar file from releases If you downloaded the release tarball, you shouldn’t run ./autogen.sh at all, just run steps ./configure directly.

3. for ubuntu >=18.04, you can install package directly- The requirements for libraqm are:

libc6   >= 2.14
libfreetype6    >= 2.4.2
libfribidi0 >= 1.0.0
libharfbuzz0b   >= 2.1.1

Install the raqm package Update the package index:

    sudo apt-get update

Install libraqm0 deb package:

sudo apt-get install libraqm0

You can test your installation by:

from PIL import features
print(features.check("raqm"))
# you should get True now

Answer 3

Pillow 7.0.0 provides support for rendering complex font with raqm library

To check for support:

>>> from PIL import features
>>> print(features.check("raqm"))
True

If it returns False check if library is installed:

 /sbin/ldconfig -p | grep raqm
    libraqm.so.0 (libc6,x86-64) => /usr/lib/libraqm.so.0
    libraqm.so (libc6,x86-64) => /usr/lib/libraqm.so

To Install raqm in debian based distros: sudo apt-get install libraqm-dev

To use raqm as layout engine add layout_engine option while initializing font:

font = ImageFont.truetype("foo.ttf", size=90, layout_engine=ImageFont.LAYOUT_RAQM)

The above code is tested for: Hindi, Marathi, Gujrati and Telugu fonts.
