It is useful for converting scanned images +and some drawing conversion. + +<P>Memory is used very liberally with at least 6 bytes needed for +every pixel. Large bitmap PICT files will likely run your computer +out of memory. + +<h2 id="fonts">FONTS</h2> + +<p>Some of the information in a PICT file is text, with a number +indicating the font in which the text is supposed to rendered. +<b>picttoppm</b> has one built-in font, but you can add others by +directing <b>picttoppm</b> to BDF font files, which you do with font +directory files. + +<p><b>picttoppm</b> automatically uses the file named <b>fontdir</b> +in the current directory, if it exists. You may specify an additional +font directory file with the <b>-fontdir</b> option. + +<P>Obviously the font defintions are strongly related to the +Macintosh. You can find more font numbers and information about fonts +in Macintosh documentation. + +<H3 id="fontdir">FONT DIR FILE FORMAT</H3> + +<p>Each line in the file is either a comment or font information. A +comment begins with <b>#</b>. The font information consists of 4 +whitespace spearated fields. The first is the font number, the second +is the font size in pixels, the third is the font style and the fourth +is the name of a BDF file containing the font. The BDF format is +defined by the X Window System and is beyond the scope of this document. + +<P>The font number indicates the type face.
