## Member Function Documentation

const PdfDict * PdfDict::dict | ( |  | ) | const
| virtualnoexcept

Return this object as PDF dictionary object.

Reimplemented from ipe::PdfObj.

Referenced by ipe::PdfFile::parse().

String PdfDict::dictRepr | ( |  | ) | const
| noexcept

Return PDF representation of the PdfDict without the stream.

void PdfDict::dictWrite | ( | Stream & | stream,
|  | const PdfRenumber * | renumber,
|  | bool | inflate,
|  | int | length
| ) |  | const
| noexcept

void PdfDict::write | ( | Stream & | stream,
|  | const PdfRenumber * | renumber,
|  | bool | inflate
| ) |  | const
| virtualnoexcept

Implements ipe::PdfObj.

References ipe::Buffer::size().

void PdfDict::setStream | ( | const Buffer & | stream | ) |

Add stream data to this dictionary.

void PdfDict::add | ( | String | key,
|  | const PdfObj * | obj
| ) |  |

Add a (key, value) pair to the dictionary.

Dictionary takes ownership of obj.

Referenced by ipe::PdfResources::collect().

const PdfObj * PdfDict::get | ( | String | key,
|  | const PdfFile * | file
| ) |  | const
| noexcept

Look up key in dictionary.

Indirect objects (references) are looked up if file is not nullptr, and the object referred to is returned. Returns nullptr if key is not in dictionary.

bool PdfDict::getNumber | ( | String | key,
|  | double & | val,
|  | const PdfFile * | file
| ) |  | const
| noexcept

Retrieve a single number and stor in val.

References ipe::PdfObj::number(), and ipe::PdfNumber::value().

Referenced by ipe::Latex::createLatexSource().

bool PdfDict::getNumberArray | ( | String | key,
|  | const PdfFile * | file,
|  | std::vector< double > & | vals
| ) |  | const
| noexcept

Retrieve an array of numbers and store in vals.

| inlinenoexcept

Referenced by ipe::Document::formatFromFilename(), ipe::Face::glyphIndex(), and ipe::PdfWriter::~PdfWriter().

bool PdfDict::deflated | ( |  | ) | const
| noexcept

Is this stream compressed with flate compression?

References ipe::PdfObj::name(), and ipe::PdfName::value().

Referenced by ipe::Document::formatFromFilename(), and ipe::PdfWriter::~PdfWriter().

Buffer PdfDict::inflate | ( |  | ) | const
