Ensuring Consistent Spacing: Macro Techniques For Automatic Latex Figure Centering

Centering Figures Automatically

The core problem of inconsistent figure placement in LaTeX stems from the automated positioning algorithms. Figures may shift between left, right, and centered alignment based on complex rules for avoiding overflowing margins and text overlap. This can cause a jarring reading experience with figures placed sporadically.

The float and caption packages provide macros to override the default positioning with consistent centered figure alignment. The \centering command inside a figure environment signals LaTeX to prioritize center positioning for that image. Additionally, the center option for the figure environment ensures centered alignment even when overflow occurs:

\begin{figure}[H]
  \centering
    \includegraphics[width=\linewidth]{figure.png}
    \caption{A centered figure} 
  \label{fig:my_figure}
\end{figure}  

This code robustly centers figures while allowing wrapping text to adjust automatically. The [H] parameter forces the figure to the exact location in the source to prevent unintended spacing.

Spacing Around Figures

Consistent spacing around figures requires setting uniform vertical margins with macros like \vspace. Placing \vspace{.5cm} before or after a figure environment consistently separates the image from surrounding text.

Spacing macros clearly communicate intent when inserted before figures. This prevents large text blocks accidentally aligning next to an image. Spacing after figures improves aesthetics by separating the caption from trailing paragraphs.

\vspace{.5cm}
\begin{figure}[H]
  \centering
    \includegraphics[width=\linewidth]{figure.png}
    \caption{A figure with spacing before}
  \label{fig:spacing_before} 
\end{figure}
\vspace{.5cm}

The spacing macros pad both sides of the figure consistently without manual guesses at paragraph alignments.

Figure Alignment Relative to Text

Precise figure alignment involves left, right, and centered positioning relative to text blocks. The wrapfigure environment flows text around a left or right-aligned figure, while minipage allows aligned miniature pages for side content.

Nesting the wrapfigure syntax around a figure pushes text to only one side. The r and l options specify right or left alignment at a given width:

\begin{wrapfigure}{r}{0.5\textwidth}
  \begin{figure}
    \centering
     \includegraphics[width=\linewidth]{figure.png}
     \caption{A right-aligned image}
   \end{figure}
 \end{wrapfigure}
This text block wraps around the right-aligned figure...

For independent pages with left-right centering, minipage surrounds self-contained content flowed inline:

\begin{minipage}[c]{0.5\textwidth}
  \centering
   \includegraphics[width=\linewidth]{figure.png}
   \captionof{figure}{A minipage figure}\\
\end{minipage}
Text blocks before and after this centered content...  

These environments give precise control over figure text wrapping at specified alignments.

Troubleshooting Improper Figure Spacing

Troubleshooting uneven figure spacing requires debugging LaTeX's automated positioning algorithms. The float package's H forces in-place rendering to verify intended figure locations.

Alternatively, the [H] location modifier attached to the figure environment overrides the positioning system entirely. This locks images to the source order and spacing without disturbances from margin detection:

\begin{figure}[H]
  \centering
    \includegraphics[width=\linewidth]{figure.png}
    \caption{A forced in-place figure}
  \label{fig:troubleshoot} 
\end{figure}

Manually fixing misalignments through trial-and-error spacing tuning often becomes necessary as well. Balancing automatic placement with forced [H] figures and manual spacers enables proper control over figure positioning.

Achieving Publication-Quality Figure Placement

Publications like academic journals impose strict specifications on figure size, alignment, spacing and numbering. Automated solutions through packages like float provide convenient defaults. However, achieving publication standards requires carefully overriding these automated choices.

Most publications suggest centering figures prefixed by consistent spacing. Numbers should appear sequentially according to first reference order. Captions follow established stylistic guidelines. While labeling and macro packages handle numbering and captions, authors must manually ensure captivating centering through mindful spacing, alignment and troubleshooting.

With diligence balancing automation and precision, authors can fulfill specific publication requirements for conveying information through consistently positioned figures.
