CP and raw fonts</A></H2> <P>PSF is the Linux standard font format, but various old and very obsolete formats still exist. <P>CP font files are just fragments of CPI fonts, obtained by concatenating <CODE>CPEntryHeader</CODE> (28 bytes), <CODE>FontDataHeader</CODE> (6 bytes), and for each font <CODE>ScreenFontHeader</CODE> (6 bytes) and <CODE>ScreenFontData</CODE>, that is, the part of a CPI font describing one code page. <P>(History: the first <CODE>.cp</CODE> files used with Linux that I know of were <CODE>972.cp</CODE> and <CODE>880.cp</CODE> included in <CODE>codepage.tar.gz</CODE> by Joel M. Hoffman, dated June 14, 1992. Support for such files was added in <CODE>kbd-0.84</CODE>.) <P>Of the <CODE>CPEntryHeader</CODE>, the only meaningful field is <CODE>codepage</CODE>. Of the <CODE>FontDataHeader</CODE>, the only meaningful fields are <CODE>num_fonts</CODE> (1 or 3) and <CODE>size</CODE>, giving the size of the following <CODE>ScreenFontData</CODE>. A CP file containing three fonts of pointsizes 16, 14, 8 will have size 34+(6+16*256)+(6+14*256)+(6+8*256) = 9780 bytes, with the three fonts at offsets 40, 4142, 7732. A CP file containing one font of point size 16 will have size 34+(6+16*256) = 4136 bytes, with the font at offset 40. <P>There are other sources of fonts, and binary files with a length that is a multiple of 256 or a multiple of 256 plus 40 are accepted as possible binary font data (perhaps with a 40-byte header) for fonts of size 256. <P>Binary font files of size 32768 are treated as binary font data for a 512-char font of height 32. Such files are written by the obsolete <CODE>restorefont -w</CODE>. <HR> Next <A HREF="font-formats-3.html">Previous</A> <A HREF="font-formats.html#toc4">Contents</A> </BODY> </HTML>
