/*
|
||
* CharStrings are encoded following the the CharString Encoding sequence
|
||
* describe in Chapter 6 of the "Adobe Type1 Font Format" specification.
|
||
* The value in a byte indicates a command, a number, or subsequent bytes
|
||
* that are to be interpreted in a special way.
|
||
*
|
||
* CharString Number Encoding:
|
||
* A CharString byte containing the values from 32 through 255 inclusive
|
||
* indicate an integer. These values are decoded in four ranges.
|
||
*
|
||
* 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
|
||
* indicate the integer v - 139. Thus, the integer values from -107 through
|
||
* 107 inclusive may be encoded in single byte.
|
||
*
|
||
* 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
|
||
* indicates an integer involving the next byte, w, according to the formula:
|
||
* [(v - 247) x 256] + w + 108
|
||
*
|
||
* 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
|
||
* indicates an integer involving the next byte, w, according to the formula:
|
||
* -[(v - 251) * 256] - w - 108
|
||
*
|
||
* 4. A CharString containing the value 255 indicates that the next 4 bytes
|
||
* are a two complement signed integer. The first of these bytes contains the
|
||
* highest order bits, the second byte contains the next higher order bits
|
||
* and the fourth byte contain the lowest order bits.
|
||
*
|
||
*
|
||
* CharString Command Encoding:
|
||
* CharStrings commands are encoded in 1 or 2 bytes.
|
||
*
|
||
* Single byte commands are encoded in 1 byte that contains a value between
|
||
* 0 and 31 inclusive.
|
||
* If a command byte contains the value 12, then the value in the next byte
|
||
* indicates a command. This "escape" mechanism allows many extra commands
|
||
* to be encoded and this encoding technique helps to minimize the length of
|
||
* the charStrings.
