[Tex/LaTex] Counter too large ERROR when it shouldn’t

subfloats

My Latex document suddenly stopped compiling and raising the "! LaTeX Error: Counter too large." error for no apparent reason. It compiled before, with the same amount of figures and subfigures, but even by erasing the things I added since the last time it compiled, it just doesn't work anymore.

I know what generally causes this error => when captioning more than 26 subfigures, it runs out of letter to label the subfigures and throws this error. This is not my case. My largest figure only has 8 subfigures so I don't know why it doesn't work.

Here's part of my code (more figures come before this):

I know I didn't used the most straightforward method to create my tables, and I could have used a minipage for my subfigures instead. But if possible I would like to keep those "tables with subfigures" as they are (with minor changes if necessary to fix the problem ofc).

Best Answer

I get no error and also the reset of subfigure numbering if I remove tabularx, that's probably the cause for the issue.

You simply don't need it just for setting multiple subfigures.

I also changed Thesis to book, as it's impossible to know what class you're loading.

In the example, I used height=2cm in order not to get too large floats.

[Tex/LaTex] Error using russian letters for appendix counter with hyperref and subfig

The subfig package is known to have problems with hyperref. You could give my subcaption package a try instead:


\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[config,font=small,labelsep=period]{caption}
\usepackage{subcaption}
\usepackage[unicode]{hyperref}

\makeatletter
  \gdef\thechapter{\@Asbuk\c@chapter}

\chapter{Sample Appendix}

Reference \ref{fig_images}, also \ref{fig_image1} and \ref{fig_image2}.

\begin{figure}
  \centering
  \subcaptionbox{\label{fig_image1}}{\includegraphics[width=0.15\linewidth]{image1}}
  \hspace{0.15\linewidth}
  \subcaptionbox{\label{fig_image2}}{\includegraphics[width=0.15\linewidth]{image2}}
  \caption[]{\label{fig_images}
    Images:
    \subref{fig_image1}~---~first;
    \subref{fig_image2}~---~second;
  }
\end{figure}

\end{document}

(I'm sorry for the shameless self-advertisement, but the problems of subfig with hyperref were one of the many reasons why I wrote the subcaption package.)

Addendum:

As opposite to the subfig package the subcaption package will only typeout the value of \thesubfigure resp. \thesubtable as reference since this is the behaviour of all other references as well, e.g. references to figures or sections. So if one want to have the parenthesis (or other decorative elements) in references, one have to add them there and remove them from the label format (so they will not appear twice there), e.g. by using the option labelformat=simple. For example:


\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[config,font=small,labelsep=period]{caption}
\usepackage[labelformat=simple]{subcaption}
\usepackage[unicode]{hyperref}

%use russian alphabet for subfigure counter

  \def\thesubfigure{(\textit{\asbuk{subfigure}})}
  \providecommand\thefigsubsep{,~}
  \def\p@subfigure{\@nameuse{thefigure}\thefigsubsep}
\makeatother

  \caption[]{\label{fig_images}
    Images:

    \subref{fig_image2}~---~second;
  }
\end{figure}

\end{document}

2nd Addendum (updated on 2011/08/19):

The subcaption package does support different look & feel for references and sub-references since version 1.1 from 2011/08/18, using the new option "subrefformat=". For example:


\documentclass[a4paper]{book}

[Tex/LaTex] Error : Too many unprocesssed floats, multiple figures single page

You have shown one float (a figure). If this one is the sole cause of the too many unprocessed floats error, it almost certainly means that LaTeX is unable to place it according to the limitations it has been given. When that happens, all later figures have to wait in line (to avoid getting them out of order). If there are more than allowed to be pending (I think 18), you get this error. The morefloats package allows you to go over 18, but even so, you may find all the figures flushed at the end of the chapter or the end of the document.

You have used \begin{figure}[t!] which means it can only be put at the top of a text page. Probably it cannot fit there within the default constraints. (The default constraints are set by the class file, which you haven't mentioned.) In the article class, a top float is only allowed 70% of a page, a float bigger than that probably should go on a page by itself, so I would suggest using [tp] instead of [t!].

You could also reduce the size of the float. You can trim a little whitespace from the top and bottom by not using the center environment. Just use \centering.

Also, you can adjust the parameters that limit how much space floats can take up. For example:

\renewcommand{\topfraction}{0.8}
\renewcommand{\textfraction}{0.15}

These commands would go in the preamble of your document.

Finally, as a last resort, issuing \clearpage before the problem float will cause all pending floats to be processed on the pages that follow. If this one is the only one, that is equivalent to putting it on a page by itself (the [p] option).
