Trouble generating quantum gates images

[eusta...@gmail.com]

Hello all,

I'm having trouble generating quantum gates images when using one of the methods exemplified in QIP examples.  An alternate method works suggesting I at least have the prerequisite packages installed (had to install pdf2svg and ImageMagick).  I attach a jupyter nb file showing the two.

specifically, command:

Image(filename='images/toffoli.png')

yields an error, and inspection of my local directory shows 'images/xxx.png' file is not being created.

I'd much appreciate some help in resolving this.

Thank you in advance,

eustace

At present you need the following libraries, and have them on your path, to use the features that you want:

pdflatex, pdfcrop, pdf2svg, imagemagick (convert)

These are easy to satisfy on Linux, but somewhat more difficult to do on OSX and Win.

Hello Paul,

Thank you for the fast response.  These requirements are already satisfied, so I doubt if they are the cause.  ‘convert’ was installed as part of ImageMagick installation.
