Using Imported Graphics in LaTeX and pdfLaTeX - Mirror

An additional benefit of psfrag rewrite is that it now supports compressed eps
graphics. However, the \tex command (described in Section 15.3 on Page 48) cannot
be used to embed L A TEX text in compressed graphics.
Problems
with Kerning
To use psfrag, create an eps file and then perform the following steps
1. Include \usepackage{psfrag} in the preamble of the L A TEX document.
2. In the document, use the \psfrag command to specify the eps text to replace
and the L A TEX string to replace it. This makes the specified substitution occur
in any subsequent \includegraphics command issued in the same environment.
3. Use the \includegraphics command as usual.
The L A TEX \psfrag command has the following syntax
\psfrag{PStext}[posn][PSposn][scale][rot]{text}
with its arguments described in Table 5.
The posn and PSposn options are one of the 12 points (such as [tl], [br], [cc])
shown in Figure 3 on Page 28. If the optional arguments are not issued, the point
defaults to [Bl]. Any missing letters default to c (e.g., [ ] and [c] are equivalent
to [cc], [l] is equivalent to [lc]). See [29] for examples of various combinations of
placement points.
Note that \psfrag matches entire text strings. Thus the command
\psfrag{pi}{$\pi$}
replaces the string pi with π, but does not affect the strings pi/2 or 2pi. Separate
\psfrag commands must entered for these strings.
psfrag cannot perform the replacement unless the entire eps string is constructed
with a single PostScript command. Some programs break string up into sub-strings
or individual letters in order to perform kerning. For example, Corel Draw produced
the following eps code to place the string “Hello World”
0 0 (Hello W) @t
1080 0 (orld) @t
Since psfrag sees this as two unrelated strings “Hello W” and “orld”, it cannot
perform any replacement of “Hello World”. If the kerning cannot be manually turned
off, using Courier or other monospaced fonts often prevents the kerning 21 . If the
kerning cannot be avoided, only single-character replacement strings can be used.
15.1 PSfrag Example #1
The commands
\includegraphics{pend.eps}
include the graphic without any psfrag replacement, producing Figure 9. The commands
\psfrag{q1}{$\theta_1$}
\psfrag{q2}{$\theta_2$}
\psfrag{L1}{$L_1$}
\psfrag{L2}{$L_2$}
\psfrag{P1}[][]{$P_1$}
\psfrag{P2}[][]{\large $P_2$}
\includegraphics{pend.eps}
21 In order to avoid kerning, the font may need to be set to Courier before the text is created.
That is, creating the text and then converting it to Courier may still result in kerning.
