/* |
|
* 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. |
