1. (defparameter *temp* (opticl:read-jpeg-file "/home/null/mpv-shot0002.jpg")) ==> looks good

2.(setf *temp* `(opticl:read-jpeg-file` "/home/null/mpv-shot0002.jpg")) ==>

While it keeps print three dimensional arrary in *inferior-lisp*

I'm using sbcl/2.1.3

You do realize that the second form returns the value that you setf'ed temp too? So your SLIME buffer is attempting to print the array that contains the pixels of the image. This indeed fails but this isn't an opticl bug.

I'm not sure what the backticks are there for, but can you try:

(setf *temp* (make-array '(4000 4000)))

And you'll likely see a similar error.

I see, is there anyway to avoid this? Just not use setf, but something like let/defparameter? Or is there a way to close the print? Thank you!
