Detailed Description

The model for an Ipe document.

The IpeDocument class is the engine behind the Ipe program. It represents the contents of an Ipe document, and all the methods necessary to load, save, and edit it. It is independent of a specific user interface.

IpeDocument's cannot be copied or assigned.

Note that the IpeDocument owns the IpeRepository that defines the meaning of all object's attributes. Therefore, the document is the largest extent where IpeObject's make sense. You can have several documents at once, but you cannot move IpeObject's (or IpeStyleSheet's) from one to the other. If you need to do so, you'll have to externalize them to XML and internalize them into the other document.


Member Enumeration Documentation

enum IpeDocument::TFormat
 

There are several Ipe document save formats.

Enumerator:
EXml  Save as XML.
EPdf  Save as PDF.
EEps  Save as Encapsulated Postscript.
EIpe5  Old 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.
ENoShading  Don't shade background in PDF documents.
ELastView  Create last view of each page only.
ENoColor  No color commands in EPS output.


Constructor & Destructor Documentation

IpeDocument::IpeDocument  ) 
 

Construct an empty document for filling by a client.

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

IpeDocument::~IpeDocument  ) 
 

Destructor.


Member Function Documentation

IpeDocument::TFormat IpeDocument::FileFormat IpeDataSource source  )  [static]
 

Determine format of file in source.

IpeDocument * IpeDocument::New IpeDataSource 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. If it is smaller than -60000, then it is the negative value of the Ipe version that created that file (and which exceeds the version of this Ipe).

bool IpeDocument::Save IpeTellStream stream,
IpeString  creator,
TFormat  format,
uint  flags,
int  compressLevel = 9
const
 

Save in a stream.

Returns true if sucessful.

Does not reset IsEdited().

void IpeDocument::SaveAsXml IpeStream stream,
IpeString  creator,
bool  usePdfBitmaps = false
const
 

Save in XML format into an IpeStream.

You can set creator to set the creator attribute in the

tag.

bool IpeDocument::AddStyleSheet IpeDataSource source  ) 
 

Load a style sheet and add at top of cascade.

int IpeDocument::TotalViews  )  const
 

Return total number of views in all pages.

IpePage * IpeDocument::NewPage int  gridSize  ) 
 

Create a new empty page with standard settings.

SProperties IpeDocument::Properties  )  const [inline]
 

Return document properties.

void IpeDocument::SetProperties const SProperties info  ) 
 

Set document properties.

void IpeDocument::SetStyleSheet IpeStyleSheet sheet  ) 
 

Replace the style sheet cascade.

The previous contents is not deleted (because this function is often used to insert style sheets into the cascade).

Sets the edited flag.

const IpeStyleSheet* IpeDocument::StyleSheet  )  const [inline]
 

Return const pointer to topmost stylesheet.

IpeStyleSheet* IpeDocument::GetStyleSheet  )  [inline]
 

Return modifiable stylesheet.

bool IpeDocument::IsEdited  )  const
 

Return true if document has been edited since last save.

void IpeDocument::SetEdited bool  edited  ) 
 

Set whether document has been edited.

Methods that can modify the document already set the flag, so you only need to call this when inserting or deleting pages, etc. When modifying an IpePage, rather call IpePage::SetEdited(true).

Clients need to manually reset the edited flag when they save the document, or after constructing it during loading.

Calling this with edited == false will call IpePage::SetEdited(false) for all pages.

void IpeDocument::SetFontPool IpeFontPool fontPool  ) 
 

Update the font pool (after running Pdflatex).

Takes ownership of the font pool.

const IpeFontPool* IpeDocument::FontPool  )  const [inline]
 

Return the current IpeFontPool.

void IpeDocument::FindBitmaps IpeBitmapFinder bm  )  const
 

Create a list of all bitmaps in the document.

bool IpeDocument::CheckStyle IpeAttributeSeq 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 with not duplicates) that are NOT defined.

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

IpeRepository* IpeDocument::Repository  )  [inline]
 

Return attribute repository.

const IpeRepository* IpeDocument::Repository  )  const [inline]
 

Return attribute repository (const version).
