Instance Methods | |
(FSCompareResults *) | - doCompare:compared_page_index:compare_flags: |
Compare a PDF page of base document with a PDF page in compared document. "base document" and "compared document" means the PDF documents objects that aredused to construct current object. More... | |
(FSPDFDoc *) | - generateComparedDoc: |
Compare the base document with compared document (which are used to construct current object) and then generate a PDF document as comparison result. More... | |
(id) | - initWithBase_doc:compared_doc: |
Constructor, from PDF document object. More... | |
(id) | - initWithOther: |
Constructor, with another comparison object. More... | |
(BOOL) | - isEmpty |
Check whether current object is empty or not. More... | |
This class can be used to compare one PDF file (as "base document") with another PDF file (as "compared document") page by page.
- (FSCompareResults *) doCompare: | (int) | base_page_index | |
compared_page_index: | (int) | compared_page_index | |
compare_flags: | (unsigned int) | compare_flags | |
Compare a PDF page of base document with a PDF page in compared document. "base document" and "compared document" means the PDF documents objects that aredused to construct current object.
[in] | base_page_index | Page index in base document. Valid range: from 0 to (base_page_count-1). base_page_count is returned by function FSPDFDoc::getPageCount for base document. |
[in] | compared_page_index | Page index in compared document. Valid range: from 0 to (compared_page_count-1). compared_page_count is returned by function FSPDFDoc::getPageCount for compared document. |
[in] | compare_flags | Compare type which specifies what to be compared in PDF pages. Please refer to values starting from FSComparisonCompareTypeAll and this can be one or combination of some of these values. |
- (FSPDFDoc *) generateComparedDoc: | (unsigned int) | compare_flags |
Compare the base document with compared document (which are used to construct current object) and then generate a PDF document as comparison result.
It may take a long time to compare content of two PDF documents and generate the new PDF document.
[in] | compare_flags | Compare type which specifies what to be compared in PDF pages. Please refer to values starting from FSComparisonCompareTypeAll and this can be one or combination of some of these values. |
Constructor, from PDF document object.
[in] | base_doc | A valid PDF document object as base document. |
[in] | compared_doc | A valid PDF document object as compared document. |
- (id) initWithOther: | (FSComparison*) | other |
Constructor, with another comparison object.
[in] | other | Another comparison object. |
- (BOOL) isEmpty |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
