Question

I am using floatrow package creating the box environment. if i declare the floatrow package in the tex file the normal figure framebox is affected.

MWE

\usepackage{graphics}
\usepackage{graphicx}
\usepackage{floatrow}%%%%%%%
\usepackage{lipsum}

\DeclareNewFloatType{Box}{%

  name=BOX,%

\floatsetup[Box]{%

  capposition=top,%
  justification=justified}%



\newenvironment{BOX}[2][htbp]{%

\newenvironment{BOX*}[2][htbp]{%

Before declare the floatrow package the figure environment output displayed below:

After declare the floatrow package the figure environment output displayed below:

Defined box environment using flotrow package displayed below

I don't know what is the reason to affect the figure environment if i am using floatrow package. Please advice.

Answer 1

You're already using the floatrow package, which permits you to have boxed figures simply declaring

\floatsetup[figure]{style=BOXED,captionskip=25pt}

I've added a captionskip since you want some spacing before the caption.

Then, instead of using

\begin{figure*}[!t]
\processfigure{Figure Placed here\vspace*{12pt}}
{\textbf{\boldmath Cross-link reaction for SPEEK (color code: gray C, yellow S, red O)}.\label{fig:1}}
\end{figure*}

with your custom command \processfigure to construct a box around the figure, simply use a \ffigbox in this way:

\begin{figure*}[!t]
\ffigbox[82mm]
{Figure Placed here}
{\caption{\textbf{\boldmath Cross-link reaction for SPEEK (color code: gray C, yellow S, red O)}}\label{fig:1}}
\end{figure*}
