## Detailed Description

A sound annotation (PDF 1.2) is analogous to a text annotation except that instead of a text note, it contains sound recorded from the computer's microphone or imported from a file. Sound annotation is a kind of markup annotation, so class Sound is derived from class Markup. Currently, only support to get the properties or data of a sound annotation. Not support to modify a sound annotation (including reseting appearance) yet.

## Member Enumeration Documentation

## ◆ SampleEncodingFormat

enum foxit::pdf::annots::Sound::SampleEncodingFormat

Enumeration for encoding format of sound sample data.

Values of this enumeration must be used alone.

Enumerator
e_SampleEncodingFormatRaw | Unspecified or unsigned values in the range 0 to (2^B - 1).
e_SampleEncodingFormatSigned | Twos-complement values.
e_SampleEncodingFormatMuLaw | μ-law-encoded samples
e_SampleEncodingFormatALaw | A-law-encoded samples.

## Constructor & Destructor Documentation

## ◆ Sound()

foxit::pdf::annots::Sound::Sound | ( | const Annot & | annot | ) |
| explicit

Constructor, with parent class object.

Parameters

  [in] | annot | Parent class object.

## Member Function Documentation

## ◆ GetBits()

int foxit::pdf::annots::Sound::GetBits | ( |  | ) | const

Get the number of bits per sample value per channel.

Returns
  The number of bits per sample value per channel.

## ◆ GetChannelCount()

int foxit::pdf::annots::Sound::GetChannelCount | ( |  | ) | const

Get the count of sound channels.

Returns
  The count of sound channels.

## ◆ GetCompressionFormat()

String foxit::pdf::annots::Sound::GetCompressionFormat | ( |  | ) | const

Get the name of the sound compression format used on the sample data.

Returns
  The name of the sound compression format used on the sample data.

## ◆ GetFileSpec()

FileSpec foxit::pdf::annots::Sound::GetFileSpec | ( |  | ) | const

Get the file specification object which represents an external sound file.

A sound may be defined in an external file (represented by a file specification object). The sound file should be self-describing, containing all information needed to render the sound; no additional information need be present in the PDF file.
In this case, the returned stream object should be ignored.

Returns
  A file specification object which represents an external sound file. If the return value of function FileSpec::IsEmpty for the returned file specification object is true, that means no external sound file is used for current sound annotation. In this case, please use function Sound::GetSoundStream to get the sound data.

## ◆ GetSampleEncodingFormat()

SampleEncodingFormat foxit::pdf::annots::Sound::GetSampleEncodingFormat | ( |  | ) | const

Get the encoding format for the sample data.

Returns
  The encoding format for the sample data. Please refer to values starting from Sound::e_SampleEncodingFormatRaw and this would be one of these values.

## ◆ GetSamplingRate()

float foxit::pdf::annots::Sound::GetSamplingRate | ( |  | ) | const

Get the sampling rate, in samples per second.

Returns
  The sampling rate. If there is any error, this function will return -1.

## ◆ GetSoundStream()

objects::PDFStream* foxit::pdf::annots::Sound::GetSoundStream | ( |  | ) | const

Get the stream of sound data.

The stream of sound data represents the sound and can be used to be played when the annotation is activated.
Specially, if function Sound::GetFileSpec returns a valid file specification object (whose FileSpec::IsEmpty returns false), please use that file specification object instead of the stream returned by this function.

Returns
  The stream of sound data. If there is no "Sound" entry or any error occurs, this function will return NULL.
