Before text is output with a loaded font it must be set with <a href="function.ps-setfont.html" class="function">ps_setfont()</a>. This function needs the adobe font metric file in order to calculate the space used up by the characters. A font which is loaded within a page will only be available on that page. Fonts which are to be used in the complete document have to be loaded before the first call of <a href="function.ps-begin-page.html" class="function">ps_begin_page()</a>. Calling <b>ps_findfont()</b> between pages will make that font available for all following pages. </p> <p class="para"> The name of the afm file must be <i><tt class="parameter">fontname</tt></i><i>.afm</i>. If the font shall be embedded the file <i><tt class="parameter">fontname</tt></i><i>.pfb</i> containing the font outline must be present as well. </p> <p class="para"> Calling <b>ps_findfont()</b> before the first page requires to output the postscript header which includes the BoundingBox for the whole document. Usually the BoundingBox is set with the first call of <a href="function.ps-begin-page.html" class="function">ps_begin_page()</a> which now comes after <b>ps_findfont()</b>. Consequently the BoundingBox has not been set and a warning will be issued when <b>ps_findfont()</b> is called. In order to prevent this situation, one should call <a href="function.ps-set-parameter.html" class="function">ps_set_parameter()</a> to set the BoundingBox before <b>ps_findfont()</b> is called. </p> </div> <div class="refsect1 parameters"> <h3 class="title">Parameters</h3> <p class="para"> <dl> <dt> <span class="term"><i><tt class="parameter">psdoc</tt></i></span> <dd> <p class="para"> Resource identifier of the postscript file as returned by <a href="function.ps-new.html" class="function">ps_new()</a>. </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">fontname</tt></i></span> <dd> <p class="para"> The name of the font. </p> </dd> </dt> <dt> <span class="term"><i><tt class="parameter">encoding</tt></i></span> <dd> <p class="para"> <b>ps_findfont()</b> will try to load the file passed in the parameter <i><tt class="parameter">encoding</tt></i>.
