101 * JPEG markers consist of one or more 0xFF bytes, followed by a marker
102 * code byte (which is not an FF). Here are the marker codes of interest

128 * Find the next JPEG marker and return its marker code.
133 * NB: this routine must not be used after seeing SOS marker, since it will
149 /* Get marker code byte, swallowing any duplicate FF bytes. Extra FFs
165 * Read the initial marker, which should be SOI.
186 * Most types of marker are followed by a variable-length parameter segment.
