Detailed Description

The model for an Ipe document.

The Document class represents the contents of an Ipe document, and all the methods necessary to load, save, and modify it.

Member Enumeration Documentation

There are several Ipe document formats.

EXml 

Save as XML.

EPdf 

Save as PDF.

EEps 

Encapsulated Postscript (loading only)

EIpe5 

Ancient Ipe format.

EUnknown 

Unknown file format.

anonymous enum

Options for saving Ipe documents (to PDF and Postscript)

Enumerator
ESaveNormal 

Nothing special.

EExport 

Don't include Ipe markup.

ENoZip 

Do not compress streams.

EMarkedView 

Create marked views only.

Errors that can happen while loading documents.

Enumerator
EVersionTooOld 

The version of the file is too old.

EVersionTooRecent 

The file version is newer than this Ipelib.

EFileOpenError 

Error opening the file.

ENotAnIpeFile 

The file was not created by Ipe.

anonymous enum

Error codes returned by RunLatex.

Enumerator
ErrNone 
ErrNoText 
ErrNoDir 
ErrWritingSource 
ErrOldPdfLatex 
ErrRunLatex 
ErrLatex 
ErrLatexOutput 

Constructor & Destructor Documentation

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::Document ( const Document rhs)

Copy constructor.

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

Document::~Document ( )

Destructor.

References countPages(), and page().

Member Function Documentation

Document& ipe::Document::operator= ( const Document rhs)
delete
Document::TFormat Document::fileFormat ( DataSource source)
static

Determine format of file in source.

References EEps, EIpe5, EPdf, EUnknown, EXml, and ipe::String::substr().

Document::TFormat Document::formatFromFilename ( String  fn)
static
Document * Document::load ( DataSource source,
TFormat  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.

Return total number of views in all pages.

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

Referenced by countPages().

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

Return page (const version).

The first page is no 0.

Referenced by checkStyle(), countTotalViews(), Document(), findBitmaps(), insert(), page(), ipe::PageSelector::PageSelector(), runLatex(), saveAsXml(), set(), and ~Document().

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

Return page.

The first page is no 0.

Page * Document::set ( int  no,
Page page

Replace page.

Returns the original page.

References page().

void Document::insert ( int  no,
Page page 
)

Insert a new page.

The page is inserted at index no.

void Document::push_back ( Page page)

Append a new page.

Referenced by page(), and ipe::ImlParser::parseDocument().

Page * Document::remove ( int  no)

Remove a page.

Returns the page that has been removed.

SProperties ipe::Document::properties ( ) const

Cascade* ipe::Document::cascade ( )
inline
const Cascade* ipe::Document::cascade ( ) const

Return stylesheet cascade (const version).

References cascade(), replaceCascade(), resources(), and setResources().

Cascade * Document::replaceCascade ( Cascade sheets)

Replace the entire style sheet cascade.

Takes ownership of cascade, and returns the original cascade.

Referenced by cascade().

void Document::setResources ( PdfResources resources)

Update the PDF resources (after running latex).

Takes ownership.

References ipe::ImlParser::parseStyleSheet(), and resources().

Referenced by cascade(), runLatex(), setResources(), and ipe::Thumbnail::Thumbnail().

void Document::findBitmaps ( BitmapFinder bm) const
bool Document::checkStyle ( AttributeSeq seq) const

Check all symbolic attributes in the document.

This function verifies that all symbolic attributes in the document are defined in the style sheet. It appends to seq all symbolic attributes (in no particular order, but without duplicates) that are NOT defined.

Returns true if there are no undefined symbolic attributes in the document.
