A PDF file can refer to the contents of another file by using a file specification. File specification can simply represents the file path of another file, or represents the whole content of another file, which is embedded to current PDF file.
- (BOOL) embed: | (NSString *) | file_path |
Embed the whole content of a file which is specified by file path.
When this function succeeds, the whole content of specified file will be embedded to the PDF document that current file specification belongs to.
[in] | file_path | A full path of an existing local file. |
- (BOOL) embedWithPDFObject: | (FSPDFObject*) | pdf_object |
(Only support in PDF 2.0) Embed the whole content of a PDF stream object or a PDF reference object which refers to a PDF stream object, when current file specification object is used as an associated file.
When this function succeeds, the whole content of specified PDF stream object will be embedded to the PDF document that current file specification belongs to.
[in] | pdf_object | A valid PDF object. It should be either a PDF stream object or a PDF reference object which refers to a PDF stream object. |
- (BOOL) embedWithStreamCallback: | (id<FSFileStreamCallback>) | stream |
Embed a file by using FSFileStreamCallback.
When this function succeeds, please keep input stream callback object valid until the PDF file (which current file specification belongs to) is saved or closed.
[in] | stream | A FSFileStreamCallback object which is implemented by user to read the file content. |
- (BOOL) exportToFile: | (NSString *) | path |
Export the file data that represented in current file specification directly into a file.
[in] | path | A full path of a file to which the data will be saved. |
- (BOOL) exportToFileStream: | (id<FSFileStreamCallback>) | stream |
Export the file data that represented in current file specification through a stream callback object.
[in] | stream | A FSFileStreamCallback object which is implemented by user to save the file data. |
- (FSPDFDictionary *) getDict |
Get the PDF dictionary of current file specification.
- (id< FSFileReaderCallback >) getFileData |
Get the file data of embedded file.
- (long long) getFileSize |
Get the size of embedded file.
This function is only useful when current file specification object represents an embedded file. If current file specification object does not represent an embedded file, this function will return 0 directly.
- (id) initWithDocument: | (FSPDFDoc*) | document |
Constructor.
This constructor is to construct a new file specification object (without any data).
[in] | document | A valid PDF document object, to which the new file specification object will belongs. |
- (id) initWithDocument: | (FSPDFDoc*) | document | |
pdf_object: | (FSPDFObject*) | pdf_object | |
Constructor, from an existing file specification PDF object in a PDF document.
[in] | document | A valid PDF document object, to which the file specification PDF object belongs. |
[in] | pdf_object | A valid PDF object which represents an existing file specification object in the PDF document. It should be either a dictionary object or a PDF reference object:
|
- (id) initWithOther: | (FSFileSpec*) | other |
Constructor, with another file specification object.
[in] | other | Another file specification object. |
- (BOOL) isEmbedded |
Check whether current file specification object represents an embedded file or not.
- (BOOL) isEmpty |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
|
readwritenonatomicweak |
Get or Set the checksum for embedded file.
This function is only useful when current file specification object represents an embedded file. A 16-byte string that is the checksum of the bytes of the uncompressed embedded file. The checksum is calculated by applying the standard MD5 message-digest algorithm to the bytes of the embedded file stream.
If current file specification object does not represent an embedded file, this function will return an empty string.
|
readwritenonatomicweak |
Get or Set creation date and time about when the embedded file was created.
This function is only useful when current file specification object represents an embedded file. If current file specification object does not represent an embedded file, this function will return a date and time object will all value 0.
|
readwritenonatomicweak |
Get or Set modified date and time about when the embedded file was last modified.
This function is only useful when current file specification object represents an embedded file. If current file specification object does not represent an embedded file, this function will return a date and time object will all value 0.
|
readwritenonatomicweak |
(Only support in PDF 2.0) Get or Set the MIME type value for "Subtype" key for embedded file when current file specification is used as an associated file.
This function is only useful when current file specification object represents an embedded file and used as associated file.
