declares that two special properties will follow. "STARTPROPERTIES" is optional in the BDF specification. X Window allows the properties FONT_ASCENT and FONT_DESCENT to show the height above and below the baseline, respectively, for all glyphs. "FONT_ASCENT 14" declares that 14 of the 16 pixels in height are above the baseline. "FONT_DESCENT 2" declares that 2 of the 16 pixels in height are below the baseline. "ENDPROPERTIES" appears at the end of the "STARTPROPERTIES" section. "CHARS 1" declares that one character will follow. Although Adobe now refers to this file format as the Glyph BDF, they have retained the keyword "CHARS" in the final version of the specification. Lines beginning with the word "COMMENT" can be inserted within a BDF file. Anything following the "COMMENT" keyword on a line is ignored. Following the above global declarations, the following entries may repeat for each glyph. "STARTCHAR U+0041" specifies the start of a character in version 2.1 and earlier, or of a glyph in version 2.2. The string name of this particular character is "U+0041", expressing in the Unicode convention the code point hexadecimal 41 (decimal 65, the ASCII character "A"). In version 2.1 and earlier, the character name string was limited to 14 characters. In version 2.2, the glyph name string can contain up to 65,535 characters. "ENCODING 65" declares the decimal code point for this glyph in the font. "SWIDTH 500 0" declares the Scalable Width of 500 on the X-axis and 0 (default) on the Y-axis. This will result in an X-axis offset to the next glyph, but no Y-axis offset to the next glyph (i.e., the glyphs appear straight across in a line). The scalable width is 1000 times the actual point size of the character—the same unit used in an Adobe Font Metric (AFM) file. The number of pixels calculated as pixels = (scalable_width / 1000) * (resolution / 72), where scalable_width is 500 in this example, and resolution is 75 dpi for this font. Because 75 is approximately equal to 72, the number of pixels is the full width of a glyph (defined globally as 16 pixels) times 500 / 1000, or in other words the width of this glyph is 8 pixels. "DWIDTH 8 0" declares the Device Width of a glyph. In this case, after the glyph is rendered, the start of the next glyph is offset 8 pixels on the X-axis and 0 pixels
