Base PostScript encoder class.
Library: xviews or winviews or mviews (mutually exclusive)
This class allows you to encode binary data to another data representation in a PostScript compatible format. These encoders can only be used when using PostScript Level 2.
Encoders can be chained.

protected |
Initializes a new instance IlvPostScriptEncoder
instance.
stream | the output stream used by this instance. |
|
pure virtual |
Consumes a byte.
byte | The received byte. |
Implemented in IlvRunLengthEncoder, IlvASCII85Encoder, and IlvASCIIHexEncoder.
Consumes an array of bytes.
The default implementation calls consumeByte()
for each byte in the array.
count | The number of bytes. |
bytes | A pointer to the first element in the array. |
|
virtual |
Emits a byte.
byte | The emitted byte. |
Emits an array of bytes.
The default implementation calls consumeByte()
for each byte in the array.
count | The number of bytes. |
bytes | A pointer to the first element in the array. |
|
virtual |
Flushes the processed data to the output.
The default implementation does nothing.
Reimplemented in IlvRunLengthEncoder, IlvASCII85Encoder, and IlvASCIIHexEncoder.
IlvPostScriptEncoder* IlvPostScriptEncoder::getEmitter | ( | ) | const |
Return the emitter.
|
static |
Returns the full string for an encoder.
It takes into account the sub filters.
pse | A pointer to the PostScript encoder. |
|
pure virtual |
Returns a string containing the PostScript decoding filter name.
Implemented in IlvRunLengthEncoder, IlvASCII85Encoder, and IlvASCIIHexEncoder.
std::ostream* IlvPostScriptEncoder::getStream | ( | ) | const |
Return the stream used by this instance.
|
virtual |
Initializes the instance.
The default implementation does nothing.
Reimplemented in IlvRunLengthEncoder, IlvASCII85Encoder, and IlvASCIIHexEncoder.
void IlvPostScriptEncoder::setEmitter | ( | IlvPostScriptEncoder * | emitter | ) |
Sets the emitter for this encoder.
emitter | The new emitter. |
|
virtual |
Sets the output stream used by this instance.
stream | The new output stream. |
