+
+<p>dvipng attempts to handle raw PostScript. Rendering raw PostScript
+specials is done on top of the page by including a transparent image
+generated by the &lsquo;<samp><span class="samp">pngalpha</span></samp>&rsquo; device in GhostScript (automatically
+selecting &lsquo;<samp><span class="samp">truecolor</span></samp>&rsquo; mode in dvipng).
+
+ <p>Included PostScript headers are respected, and if the header
+&lsquo;<samp><span class="samp">tex.pro</span></samp>&rsquo; is included, dvipng also throws in &lsquo;<samp><span class="samp">color.pro</span></samp>&rsquo; and
+&lsquo;<samp><span class="samp">special.pro</span></samp>&rsquo;. The package &lsquo;<samp><span class="samp">xcolor</span></samp>&rsquo; includes its own headers
+with color names, and this is not only kept as a PostScript header, but
+is also read and interpreted by dvipng itself. An attempt is also made
+to respect the PGF header. The non-rendering specials from
+&lsquo;<samp><span class="samp">hyperref</span></samp>&rsquo; are handled via some heuristics and do not give an
+error.
+
+ <p>Really rendering and moving things with raw PostScript specials is more
+troublesome. The \rotatebox macro serves as a good example. The dvips
+driver of the graphicx package surrounds DVI glyphs with PostScript code
+so that after conversion by dvips, the glyphs (now themselves in
+PostScript) will be rotated in the desired way. dvipng does not handle
+this, at present. An attempt has been made to handle the rendering
+specials output by PGF (tikz), and also PSTricks. Some things work, but
+others do not. This is especially clear when mixing PostScript and DVI
+rendering commands such as glyphs. dvipng cannot at present detect if
+PostScript code moves &lsquo;<samp><span class="samp">currentpoint</span></samp>&rsquo; or rotates the frame since
+GhostScript does not return such information. A recommendation would be
+to produce images from these packages as EPS files and include them into
+your document in the standard manner.
+
+ <p>Another way to handle this would be to use a slower fallback (with dvips
+and gs, for example). If you want to disable raw PostScript handling in
+dvipng, use the switch &lsquo;<samp><span class="samp">--norawps</span></samp>&rsquo;. This switch turns off the
+internal call to GhostScript intended to display these raw PostScript
+specials. Further, when dvipng encounters raw PostScript and the gs call
+is turned off, it gives a warning. It is now possible to use the switch
+&lsquo;<samp><span class="samp">--picky</span></samp>&rsquo; to disable page rendering of pages with warnings, and use
+the slower fallback for these pages.
