tuple index out of range

[sicenul]

• I'd like to render an image to terminal console. The image is a black and white qrcode
• Executing this snippet inside python 3.7 script:

from imgrender import render
filename = 'qrcode.png'
render(filename, scale=(256, 256))

• Resulting in this following error. What is the possibility of this error?

Traceback (most recent call last):
  File "main.py", line 38, in <module>
    render(filename, scale=(256, 256))
  File "/home/yooza/python/wa-notif/env/lib/python3.7/site-packages/imgrender/main.py", line 37, in render
    image = get_image(path)
  File "/home/yooza/python/wa-notif/env/lib/python3.7/site-packages/imgrender/main.py", line 31, in get_image
    if img.shape[2] > 3:
IndexError: tuple index out of range

I've managed to reproduce this and i will fix it - I'm guessing its something to do with the way monochrome data is stored

#3

this should fix it

I released a new version with the fix - install

pip install imgrender==0.0.3

and try again

Thanks, the index error is fixed. But it looks like cannot be used for qrcode 😃
I cannot scan the qrcode because it has grey gradation, or maybe there's an option to show black and white only?
And i don't know why my qrcode showed blank. This is the sample of my image.

Thanks for sending the file over - I will have a look when I have time later in the week.
To remove the gray areas you can try making the height and width divisible by the original image size - the gray is a result of white and black pixels overlapping, and the imgrender code calculates the average colour. For a 256×256 image try a height/width of 128x128 or 64x64
