kandi X-RAY | pixd Summary
pixd is a tool for visualizing binary data using a colour palette. It is in a lot of ways akin to a hexdump tool, except using coloured squares to represent each octet. pixd uses 24-bit color SGR escape sequences. For a list of terminal emulators with support for these, see XVilka's list of supporting terminal emulators.

QUESTION
trying to run this function within a function based loosely off of this, however, since xPDF can convert PDFs to PNGs, I skipped the ImageMagick conversion step, as well as the faulty logic with the function(i) process, since pdftopng requires a root name and that is "ocrbook-000001.png" in this case and throws an error when looking for a PNG of the original PDF's file name.
My issue is now with getting Tesseract to do anything with my PNG files. I get the error:

I have also corrected my code from a static naming convention to a more dynamic one that mimics the file's original names.

I am using Swift 3 and developing an application where the user takes a photo and uses Tesseract OCR to recognize the text in it.
The following code block works.
