Member Function Documentation

create()

static JAWSMAKO_API IPDFPageExtractorPtr JawsMako::IPDFPageExtractor::create ( const IJawsMakoPtr & jawsMako, const IInputStreamPtr & inputStream, const U8String & password = U8String(), uint32 permissions = 0, const IProgressMonitorPtr & progressMonitor = IProgressMonitorPtr() )

static

Create an IPDFPageExtractor interface.

The IPDFPageExtractor interface allows extraction of pages from a PDF.

Parameters

jawsMako	The IJawsMako object.
inputStream	The input PDF stream.
password	The password to use. Assumed to be UTF-8.
permissions	The allowed permissions.

If allowed permissions is set to IDOMStandardPDFSecurityInfo::eEverythingAllowed then no checking for assembly permissions will be performed.

Otherwise, the parameter is the or'd combination of IDOMStandardPDFSecurity::ePermissionsFlags that is checked against the permissions defined in the input PDF. If an operation corresponds to a flag set in the parameter, then output will be allowed to continue. Otherwise, an IError exception with the error code JM_ERR_ASSEMBLY_WRITE_FORBIDDEN will be thrown.

If the source has no permissions information the output will proceed regardless.

The default is 0.

Parameters

progressMonitor

A smart pointer to an IProgressMonitor object which can be NULL if no such object was passed in.

Returns

IPDFPageExtractorPtr A smart pointer to the IPDFPageExtractor object.

extract()

virtual void JawsMako::IPDFPageExtractor::extract ( const IOutputStreamPtr & outputStream, uint32 pageIndex, uint32 numPages )

pure virtual

Extract a range of pages into a given output stream.

Pages are numbered starting at zero. An exception will be thrown if an invalid page range is specified.

Parameters

outputStream	The output stream.
pageIndex	The index of the first page to extract.
numPages	The number of pages to extract.

extractFrom()

virtual void JawsMako::IPDFPageExtractor::extractFrom ( const IOutputStreamPtr & outputStream, uint32 pageIndex )

pure virtual

Extract a range of pages from a given index into a given output stream.

A convenience function. Equivalent to extract(pageIndex, getNumPages());

Pages are numbered starting at zero. An exception will be thrown if an invalid page range is specified.

Parameters

outputStream	The output stream.
pageIndex	The index of the first page to extract.

extractTo()

virtual void JawsMako::IPDFPageExtractor::extractTo ( const IOutputStreamPtr & outputStream, uint32 pageIndex )

pure virtual

Extract a range of pages to a given index into a given output stream.

A convenience function. Equivalent to extract(0, pageIndex + 1);

Pages are numbered starting at zero. An exception will be thrown if an invalid page range is specified.

Parameters

outputStream	The output stream.
pageIndex	The index of the page to extract to.

getNumPages()

virtual uint32 JawsMako::IPDFPageExtractor::getNumPages ( )

pure virtual

Return the number of pages in the document.

Returns

uint32 The number of pages in the document.
