Note that you do not need to load \pkg{psfrag} separately.

+Processing pdf\/\LaTeX\ documents with \pkg{pstool} requires the `shell escape' feature of pdf\/\TeX\ to be activated.
+This allows execution of auxiliary commands from within \LaTeX, a feature which is often disabled by default for security reasons.

+Depending how you compile your \LaTeX\ document, shell escape is enabled in different ways.%

 \item[\pkgopt{process=none}] Suffixes are ignored and no \cmd\pstool\ graphics are processed.\footnote{If \pkg{pstool} is loaded in a \LaTeX\ document in \DVI\ mode, this is the option that is used since no external processing is required for these graphics.}

 \subsection{Auxiliary processing command line options}
 The command line options passed to each program of the auxiliary processing can be changed with the following package options:
 \begin{description}
-\item[\pkgopt{latex-options=...}];
-\item[\pkgopt{dvips-options=...}];
-\item[\pkgopt{ps2pdf-options=...}]; and,
-\item[\pkgopt{pdfcrop-options=...}].

+\item[\pkgopt{dvips-options=...}]
+\item[\pkgopt{ps2pdf-options=...}] and,
+\item[\pkgopt{pdfcrop-options=...}] (if applicable).
+\end{description}
+For the most part these will be unnecessary, although passing the correct options to |ps2pdf| can sometimes be a little obscure.\footnote{The manual is here: \url{http://pages.cs.wisc.edu/~ghost/doc/cvs/Ps2pdf.htm}} For example, I use the following for generating figures in my thesis:%
+\footnote{Note that each \texttt{ps2pdf} option must be quoted in Windows, which is unnecessary but does no harm in Linux and Mac~OS~X.}%
+\par{\centering|ps2pdf-options={"-dPDFSETTINGS=/prepress"}|\par}
+This forces the `base fourteen' fonts to be embedded within the individual figure files, without which some printers and \textsc{pdf} viewers have trouble with the textual labels. In fact, from v1.3 of \pkg{pstool}, this option is now the default.
+Note that subsequent calls to \pkgopt{ps2pdf-options=...} will override the \pkg{pstool} default; use |ps2pdf-options={}| to chose |ps2pdf|'s defaults if necessary.

+\subsection{Compression of bitmap data}
+In the conversion using |ps2pdf|, bitmap images are stored using either lossy or lossless compression. The default behaviour for \pkg{pstool} is to force lossless compression, because we believe that to be the most commonly desired use case (you don't want scientific graphics rendered with possible compression artifacts). This behaviour can be adjusted using one of these options:
+\begin{description}
+\item[\pkgopt{bitmap=auto}] do whatever |ps2pdf| does by default, which seems to be to use lossy compression most, if not all, of the time;
+\item[\pkgopt{bitmap=lossy}] bitmap images are compressed like \textsc{jpg}; this is only really suitable for photographs;
+\item[\pkgopt{bitmap=lossless}] bitmap images are compressed like \textsc{png}; this is suitable for screenshots and generated data such as a surface plot within Matlab (\emph{default}).
 \end{description}
-For the most part these will be unnecessary, although passing the correct options to |ps2pdf| can sometimes be a little obscure. For example, I use the following for generating figures in my thesis:\par
-{\centering|ps2pdf-options={-dCompatibilityLevel=1.4 -dPDFSETTINGS=/prepress}|\par}
-I believe this incantation forces fonts to be embedded within the individual figure files, without which some printers and \textsc{pdf} viewers have trouble with the textual labels.
+These are just special cases of the \pkgopt{ps2pdf-options=...} option, but using \pkgopt{bitmap=...} is much more convenient since the |ps2pdf| options to effect this behaviour are quite verbose.
+Note that the |auto| and |lossy| outputs differ in quality; |lossy| is lower quality than |auto| even when the latter uses a lossy compression scheme. Adjusting the quality for these options is only possible with relatively complex Ghostscript options.
