tikz package causing error in IEEE access template

Question

I have been trying for a while to load the tikz package to the IEEE ACCESS template. Whenever I use the command \usepackage{tikz}, I am getting the error

/usr/local/texlive/2017/texmf-dist/tex/generic/pgf/math/pgfmathfunctions.random.code.tex, line 33
Missing number, treated as zero.

It was working fine with the IEEEtran template and I was able to draw my circuit diagrams in that.

Anyone has any idea how to solve this issue?

Answer 1

I had the same problem and here are my steps to fix it:

• In ieeeaccess.cls change \def\year to \def\Year
• Remove all \usepackage{xcolor} in the .tex file
• To fix the missing title color, add the following code AFTER \usepackage{tikz} in the .tex file

  \NewSpotColorSpace{PANTONE}
  \AddSpotColor{PANTONE} {PANTONE3015C} {PANTONE\SpotSpace 3015\SpotSpace C} {1 0.3 0 0.2}
  \SetPageColorSpace{PANTONE}%

Note: above code is copied from the ieeeaccess.cls file line 127 ~ 129.

Hope this help.

Here is what I had to do to get tikz working with the IEEE Access template:

1. in ieeeaccess.cls change \def\year to \def\Year

2. in ieeeaccess.cls comment \RequirePackage{color}

3. in ieeeaccess.cls change \RequirePackage{spotcolor} to \RequirePackage{xspotcolor}

4. in main file add \RequirePackage{tikz} before \documentclass{ieeeaccess}

5. get xspotcolor.dtx from How to use the PANTONE color (SPOT color) in LaTeX2e version and compile with pdflatex xspotcolor.dtx and copy the resulting xspotcolor.sty to directory with tex files

6. copy spotcolor.sty from Tex installation to directory with tex files and comment \RequirePackage[pdftex]{graphics}

It might be an ugly workaround, but it works...

Answer 3

My fix for the current IEEE Access Latex template archive is as follows (see this year workaround):

% FIX ieeeaccess
% - rename files *logo.png to *Logo.png
% - use workaround with oldyear and setyear
\let\oldyear\year
\documentclass{ieeeaccess}
\let\setyear\year
\let\year\oldyear

When I try to include tikz (via \usepackage{tikz}) all colored text (e.g., title, section headings) disappears.

tikz does not work because of spotcolor's incompatibility with xcolor used by tikz (see definition of accessblue with spotcolor PANTONE in ieeeaccess.cls).

Using \RequirePackage{tikz} gives me an option clash error. My workaround for tikz is to generate pdf-figures from the tikz-tex files and then use \includegraphics.

Answer 4

Same thing as in Conflict between TikZ and university thesis class file In line 359 of ieeeaccess.cls you'll find

\def\year#1{\gdef\theyear{#1}}

Change it to

\def\Year#1{\gdef\theyear{#1}}

What the class uses the \year macro for, is to set the year of publishing (as I understand it). So with the change suggested above, you'll need to use \Year{2018} instead of \year{2018}. That year is printed in the footer.

Answer 5

I had the same issues with the changes package and IEEE Access style. This is my solution, which also removes all warnings:

At the start of the document, add this before and after including the IEEE access style:

\let\TeXyear\year
\documentclass{ieeeaccess}
\let\setyear\year
\let\year\TeXyear

Then, immediately after including the conflicting package (changes in my case), add the following:

\NewSpotColorSpace{PANTONE}
\AddSpotColor{PANTONE} {PANTONE3015C} {PANTONE\SpotSpace 3015\SpotSpace C} {1 0.3 0 0.2}
\SetPageColorSpace{PANTONE}
\definecolor{accessblue}{cmyk}{.24,1,1,0}
\definecolor{greycolor}{cmyk}{0,0,0,1}

This solves all errors and warnings. The solution of @pddthinh only solves the errors, not the warnings.

Answer 6

I just wanted to add comment to Merlijn's answers, but since I am still a noob, here is the answer.

I have a problem with tcolorbox package when using IEEE Access style document.

Merlijn' answer does the job, but in my case, it gives wrong color: red and almost black instead of blue and grey.

So in my case, I put this right after the conflicting (tcolorbox) package:

\definecolor{accessblue}{cmyk}{1, 0.3, 0, 0.2}
\definecolor{greycolor}{cmyk}{0,0,0,.8}

For completeness, these are what I do to remove errors and all warning:

1. Put this around the IEEE Access document class declaration:

\let\TeXyear\year
\documentclass{ieeeaccess}
\let\setyear\year
\let\year\TeXyear

2. Right after usepackage{tcolorbox}, add this:

\definecolor{accessblue}{cmyk}{1, 0.3, 0, 0.2}
\definecolor{greycolor}{cmyk}{0,0,0,.8}

That's all.

(Note that I do not need to add

\NewSpotColorSpace{PANTONE}
\AddSpotColor{PANTONE} {PANTONE3015C} {PANTONE\SpotSpace 3015\SpotSpace C} {1 0.3 0 0.2}
\SetPageColorSpace{PANTONE}

)

Answer 7

Merlijn's and Harashta answers worked fine for me and are far simpler than any other solutions posted here.

But since this is a question regarding a problem with tikz package and the IEEE template, to avoid any confusion, I would just add to Harashta answer that the two lines:

\definecolor{accessblue}{cmyk}{1, 0.3, 0, 0.2}
\definecolor{greycolor}{cmyk}{0,0,0,.8}

need to be after \usepackage{tikz} line:

\usepackage{tikz}
\definecolor{accessblue}{cmyk}{1, 0.3, 0, 0.2}
\definecolor{greycolor}{cmyk}{0,0,0,.8}

I'm doing this clarification because in my case I don't have the usepackage{tcolorbox} line.
