ImageMagick causing captcha to be black out - imagemagick

Question

I am having issues with ImageMagick. I downloaded ImageMagick through Homebrew and for some reason the captcha appears blacked out.
This is what I am getting:
Here is the ImageMagick version I am using:
Hamels-MacBook-Air:gitreports HD$ magick -version
Version: ImageMagick 7.0.5-4 Q16 x86_64 2017-03-25 http://www.imagemagick.org

License: http://www.imagemagick.org/script/license.php
Features: Cipher DPC HDRI Modules
Delegates (built-in): bzlib freetype jng jpeg ltdl lzma png tiff xml zlib
Also this is what I am receiving in the console:

Answer 1

As I said in my comments the code posted by #emcconville worked for me on a windows PC.
It failed when using magick and as I suspected magick ( V7 ) needs the operators in a different order as it is stricter than V6. So this worked again for me on my PC:
magick -size 100x28 -background white -gravity Center -fill darkblue -pointsize 22 label:12345 -wave 2x92 -implode 0.2 "E:\Pictures\temp.jpg"
I would guess SimpleCapture is not V7 compatible; have you a V6 version you could try?
I am using a V7 version but it also has a legacy V6 version built in but might not work on a mac?
