ImageDraw support for Bangla language

[menon92]

I am trying to convert Bangla text to Image using PIL ImageDraw method. To do this is use following code,

from PIL import ImageFont, Image, ImageDraw, ImageChops, ImageOps

w, h = 64, 64
w0, h0 = 256, 256
blank = Image.new('L', (w0 * 5, h0 * 3), 255)
font = '/path/to/font/Siyamrupali.ttf'
font = ImageFont.truetype(font, 20)  
char = 'দৃষ্টিভঙ্গি'
img = Image.new("L", (w0 * 5, h0 * 3), 255) 
draw = ImageDraw.Draw(img)
draw.text((w0, h0), char, font=font)
diff = ImageChops.difference(img, blank)
lx, ly, hx, hy = diff.getbbox()
img = img.crop((lx, ly, hx, hy))
img.save('image' + '.png')

It should convert text দৃষ্টিভঙ্গি to .png file. It does

But the image is broken like below

My OS, Python and Pillow versions

• OS: Ubuntu 14.04 LTS
• Python: 3.6.3
• Pillow: 4.2.1

If I mention that complex text rendering can be used through setting the ImageFont.truetype layout_engine argument to raqm, is that new and helpful information?

@radarhere
I replace line
font = ImageFont.truetype(font, 20)
by
font = ImageFont.truetype(font=font, size=20, layout_engine=ImageFont.LAYOUT_RAQM)

still It generate same broken image

Okay. Loading up a VM instance of Ubuntu 14.04, I tried your script, and it didn't work.
I installed libharfbuzz-dev and libfribidi-dev, re-installed Pillow, and it didn't work.
I then ran depends/install_raqm.sh, re-installed Pillow, and without requiring the layout_engine=ImageFont.LAYOUT_RAQM option, it worked.

So I expect if you try some combination of that, you should find a solution.

Excellent.

The following worked for me on Ubuntu 18.04 with Python3.6.7:

0. sudo pip3 install Pillow -> installs 5.4.1
1. sudo apt-get install libfreetype6-dev libharfbuzz-dev libfribidi-dev gtk-doc-tools
2. Install libraqm as described here (using configure, make, make install)
3. sudo ldconfig This step was needed!
4. 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()

@menon92 Did you find any solution for this problem? I am facing the same problem. If find any solution please help me. Thank you.

how do i fix it for windows?

Regarding the question from @nazmul284, @menon92 liked this comment, so I presume that worked for them.

@zarif25 I suggest installing raqm. https://stackoverflow.com/questions/62939101/how-to-install-pre-built-pillow-wheel-with-libraqm-dlls-on-windows might interest you.

I followed this comment and could solve the problem in Ubuntu eventually.

Step 1: !sudo apt-get install libfreetype6-dev libharfbuzz-dev libfribidi-dev gtk-doc-tools
Step 2: !wget -O raqm-0.7.0.tar.gz https://raw.githubusercontent.com/python-pillow/pillow-depends/master/raqm-0.7.0.tar.gz
Now the raqm-0.7.0.tar.gz file should be in your downloads section.
Step 3: !tar -xzvf raqm-0.7.0.tar.gz
Step 4: !cd raqm-0.7.0
Step 5: !./configure --prefix=/usr && make -j4 && sudo make -j4 install
Step 6: Now you just have to reinstall the Pillow library. Activate the correct environment. Then run the following commands:
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow

That's it! Now you have a working Pillow library that can produce proper Bengali and other Indic fonts in the image.

I found a workaround for windows 10 (64 bit).

As followed this answer, I put both libraqm.dll and fribidi-0.dll (found in x64 folder and downloaded from pillow_website ) in python.exe folder
and added to the PATH variable.

After that it worked for me.
