It is possible to manipulate the stream which can be appended to the object (if the object is of underlying type dictionary). A PdfObject is uniquely identified by an object number and a generation number which has to be passed to the constructor.
The object can be written to a file easily using the WriteObject() function.
|
Create a PDF object with object and generation number -1 and the value of being an empty PdfDictionary. |
|
Construct a new PDF object of type PdfDictionary.
|
|
Construct a new PDF object.
|
|
Create a PDF object with object and generation number -1 and the value of the passed variant.
|
|
Construct a PdfObject with object and generation number -1 and a bool as value.
|
|
Construct a PdfObject with object and generation number -1 and a pdf_int64 as value.
|
|
Construct a PdfObject with object and generation number -1 and a double as value.
|
|
Construct a PdfObject with object and generation number -1 and a PdfString as value.
|
|
Construct a PdfObject with object and generation number -1 and a PdfName as value.
|
|
Construct a PdfObject with object and generation number -1 and a PdfReference as value.
|
|
Construct a PdfObject with object and generation number -1 and a PdfArray as value.
|
|
Construct a PdfObject with object and generation number -1 and a PdfDictionary as value.
|
|
Creates a copy of an existing PdfObject All assosiated objects and streams will be copied along with the PdfObject
|
|
Dynamically load this object and any associated stream from a PDF file by calling the virtual method DelayedStreamLoadImpl if the stream is not already loaded. Will call DelayedLoad() first if it is required. Call graph: DelayedStreamLoad ---> DelayedLoad() --> DelayedLoadImpl() | --> DelayedStreamLoadImpl() For objects complete created in memory this function does nothing. |
|
Load the stream of the object if it has one and if delayed loading is enabled. You should override this to control deferred stream loading in your subclass. Never call this method directly; use DelayedStreamLoad() instead. Reimplemented in PoDoFo::PdfParserObject. |
|
Flag any stream associated with the object as incompletely loaded, so that DelayedStreamLoad() will be called when needed. All constructors initialize a PdfObject with delayed loading of streams disabled . If you want delayed loading of streams you must ask for it. If you do so, call this method early in your ctor and be sure to override DelayedStreamLoadImpl() Note that it is quite possible to have a PdfObject that requires a delayed-load of its stream but does an immediate load of the PdfVariant base. If you want to delay loading of that too, make sure to call EnableDelayedLoading(). |
|
This function compresses any currently set stream using the FlateDecode algorithm. JPEG compressed streams will not be compressed again using this function. Entries to the filter dictionary will be added if necessary. |
|
Calculate the byte offset of the key pszKey from the start of the object if the object was written to disk at the moment of calling this function. This function is very calculation intensive!
|
|
Get the keys value out of the dictionary. If the key is a reference, the reference is resolved and the object pointed to by the reference is returned.
|
|
Get the length of the object in bytes if it was written to disk now.
|
|
Get the owner of this object.
|
|
Get a handle to a const PDF stream object If the PDF object does not have a stream, null is returned
|
|
Get a handle to a PDF stream object If the PDF object does not have a stream, one will be created.
|
|
Same as GetStream() but won't trigger a delayed load, so it's safe for use while a delayed load is in progress. This will set the dirty flag of this object.
|
|
Check if this object has a PdfStream object appended.
|
|
MustGetIndirectKey() wraps GetIndirectKey to throw on null return. This makes it MUCH more readable to look up deep chains of linked keys with the cost that it's not easy to tell at which point a missing key/object was encountered.
|
|
This operator is required for sorting a list of PdfObjects. It compares the objectnumber. If objectnumbers are equal, the generation number is compared. |
|
Creates a copy of an existing PdfObject All assosiated objects and streams will be copied along with the PdfObject
|
|
Comperasion operator. Compares two PDF object only based on their object and generation number |
|
Get a indirect reference to this object
|
|
Set the owner of this object, i.e. the PdfVecObjects to which this object belongs.
|
|
Write the complete object to a file.
