C.2.2 Using <A NAME="tex2html1781"
  HREF="../man/ps2raster.html"><I><B>ps2raster</B></I></A>
</H2>

<P>
The remedy to all the problems mentioned in the previous section is readily available to you in the form of the <A NAME="tex2html1782"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> utility <A NAME="tex2html1783"
  HREF="../man/ps2raster.html"><I><B>ps2raster</B></I></A><A NAME="31053"></A>. It is designed to provide the best quality PDF and raster files using <I>ghostscript</I><A NAME="31057"></A> as a rendering engine. The program <A NAME="tex2html1784"
  HREF="../man/ps2raster.html"><I><B>ps2raster</B></I></A><A NAME="31061"></A> avoids anti-aliasing and lossy compression techniques that are default to <I>ghostscript</I><A NAME="31065"></A> and includes the fonts into the resulting PDF file to ensure portability. By default the fonts are rendered at 720 dots-per-inch in a PDF file and images are sampled to 300 dpi, but that can be changed with the <B>-E</B> option. Simply run
<PRE>
ps2raster -A -P -Tf *.ps
</PRE>to convert all <I>PostScript</I> files to PDF while cropping it to the smallest possible BoundingBox. Or use the <B>-Tg</B> option to convert your files to PNG.

<P>
The <B>-P</B> option of <A NAME="tex2html1785"
  HREF="../man/ps2raster.html"><I><B>ps2raster</B></I></A><A NAME="31073"></A> may also come in handy. When you have <I>not</I> supplied the <B>-P</B> option in your first <A NAME="tex2html1786"
  HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> plot command, your plot will be in Landscape mode. That means that the plot will be rotated 90 degrees (anti-clockwise) to fit on a Portrait mode page when coming out of the printer. The <B>-P</B> option of <A NAME="tex2html1787"
  HREF="../man/ps2raster.html"><I><B>ps2raster</B></I></A><A NAME="31083"></A> will undo that rotation, so that you do not have to do so within your document. This will only affect Landscape plots; Portrait plots will not be rotated.
