Discussion on: How Haptik generates images on the fly with Python

[Morris Warachi]

Hey, great tutorial.
Although I keep running into an "IndexError: byteArray index out of range".
My code is just as yours is. I have even copy pasted the code directly.

Thanks Morris

Can you please tell me at which line you are getting this error?

Thanks

Thanks Morris,

Looks like you don't have fonts installed on your system. I missed this step in the post. The way Pillow works is that it builds on top of the fonts installed in the system. To fix the errors you are getting please install the fonts by following:

Ubuntu: How to install fonts on Ubuntu

For macOS and Windows just open the fonts files which you have downloaded.

Thanks for the response Vinay Jain. I will try installing the Roboto font and see if it works. Again, thanks for the help.
