Constructor & Destructor Documentation

◆ Document() [1/2]

Document::Document ( )

Construct an empty document for filling by a client.

As constructed, it has no pages, A4 media, and only the standard style sheet.

References ipe::Cascade::insert(), and ipe::StyleSheet::standard().

Referenced by formatFromFilename().

◆ Document() [2/2]

Document::Document ( const Document rhs)

Copy constructor.

References countPages(), ipe::DataSource::getChar(), and page().

◆ ~Document()

Document::~Document ( )

Destructor.

References countPages(), and page().

Member Function Documentation

◆ operator=()

Document& ipe::Document::operator= ( const Document rhs)
delete

◆ fileFormat()

FileFormat Document::fileFormat ( DataSource source)
static

Determine format of file in source.

References ipe::Eps, ipe::Ipe5, ipe::Pdf, ipe::String::substr(), ipe::Unknown, and ipe::Xml.

Referenced by load().

◆ formatFromFilename()

FileFormat Document::formatFromFilename ( String  fn)
static

◆ load() [1/2]

Document * Document::load ( DataSource source,
FileFormat  format,
int &  reason 
)
static

Construct a document from an input stream.

Returns 0 if the stream couldn't be parsed, and a reason explaining that in reason. If reason is positive, it is a file (stream) offset where parsing failed. If reason is negative, it is an error code, see Document::LoadErrors.

int &  reason 
)
static

◆ loadWithErrorReport()

bool  usePdfBitmaps = false 
) const

◆ countPages()

int ipe::Document::countPages ( ) const
inline

◆ countTotalViews()

int Document::countTotalViews ( ) const

Return total number of views in all pages.

References countPages(), ipe::Page::countViews(), and page().

◆ page() [1/2]

◆ page() [2/2]

Page* ipe::Document::page ( int  no)
inline

Return page.

The first page is no 0.

◆ findPage()

int Document::findPage ( String  s) const

Return page index given a section title or page number.

Input page numbers are 1-based strings. Returns -1 if page not found.

References countPages(), ipe::String::empty(), ipe::Lex::getInt(), page(), and ipe::Page::section().

◆ set()
