Move Pages

[millerna]

What is the fastest way to move pages, within the same document, programmatically?

Manually dragging thumbnails with the mouse, I can reorder several thousand pages instantly. Is there a way to get similar performance with code?
I’ve tried InsertPages, followed by DeletePages.
I've tried this from disk and using an already open doc.
I've tried this from Javascript.
Nothing has even come close.

Please help

Thanks

I guess the easiest way is to use JavaScript (see function movePage of Doc object) - here is a simple sample (taken from PDF JS reference) that swaps pages in the document:

Code: Select all

for (i = this.numPages - 1; i >= 0; i--) this.movePage(i);

And I'm afraid there are no other ways to make it fast and easy.

Thanks Ivan,

I’d give up easy for something fast. I think the Javascript movePage would be the easiest way to move a single page but for a range of pages it appears to be the slowest.

Here are some times that I’m seeing using a few different methods:

//Open 7000 page doc from disk
CoPDFXCview1.OpenDocument(Doc_1_LocationOnDisk, '', Doc_1_ID, PXCVA_NoUI);
Elapsed : 00:00:00.162

//insert 7000 pages into open doc from same disk location as open doc
CoPDFXCview1.DoVerb('Documents[0]', 'InsertPages', '', vDataOut, PXCVA_NoUI);
Elapsed : 00:00:24.849

//delete 7000 pages from open doc
CoPDFXCview1.DoVerb('Documents[0]', 'DeletePages', '', vDataOut, PXCVA_NoUI);
Elapsed : 00:00:00.525

//save open doc
CoPDFXCview1.SaveDocument(Doc_1_ID, Doc_1_LocationOnDisk, 0, PXCVA_NoUI);
Elapsed : 00:00:05.044

//CreateNewBlankDocument
CoPDFXCview1.DoVerb('', 'CreateNewBlankDocument', '', vDataOut, PXCVA_NoUI);
Elapsed : 00:00:00.026

//insert 7000 pages into new blank doc from first open doc
CoPDFXCview1.DoVerb('Documents[1]', 'InsertPages', '', vDataOut, PXCVA_NoUI);
Elapsed : 00:00:33.935

//close new doc
CoPDFXCview1.CloseDocument(Doc_2_ID, PXCVA_NoUI);
Elapsed : 00:00:02.365

//extract 7000 pages from first open doc into new doc
CoPDFXCview1.DoVerb('Documents[0]', 'ExtractPages', '', vDataOut, PXCVA_NoUI);
Elapsed : 00:00:22.374

//close new doc again
CoPDFXCview1.CloseDocument(Doc_2_ID,PXCVA_NoUI);
Elapsed : 00:00:01.094

//move 7000 pages within the open doc using javascript (one at a time)
CoPDFXCview1.RunJavaScript('for (i = 7000; i >= 0; i--) this.movePage(i,5);', ScriptResult, Doc_1_ID, 0);
Elapsed : 00:01:29.993

//load same doc, already open in AX viewer, using pro library
PXCp_ReadDocumentW(MyHPDF, PWChar(WideString(Doc_1_LocationOnDisk)), 0)
Elapsed : 00:00:00.023

//insert 7000 pages from same doc using pro library
PXCp_InsertPagesTo(MyHPDF, MyHPDF, @Range, 1, 0);
Elapsed : 00:00:02.836

//delete 7000 pages using pro library
for i := 0 to 6999 do PXCp_RemovePage(MyHPDF,i);
Elapsed : 00:02:04.268

//save to disk using pro library
PXCp_WriteDocumentW(MyHPDF, PWChar(WideString(Doc_1_LocationOnDisk+'2')), PXCp_CreationDisposition_Overwrite, PXCp_Write_NoRelease)
Elapsed : 00:00:06.100

//OpenDocument in AX viewer that was just written to disk by PXCp_WriteDocumentW
CoPDFXCview1.OpenDocument(Doc_1_LocationOnDisk+'2', '', Doc_2_ID, PXCVA_NoUI);
Elapsed : 00:00:00.145


Clearly, when the user drags thumbnails, the viewer is taking care of this internally with some much faster approach. I'm betting it's just manipulating the order of the page object pointers and not the actual page objects or contents directly.

Is there any chance that such functionality might be exposed through a 'MovePages' operation, in the future?

We are looking into offering this in a forth coming release sometime in June if at all possible.

That would be great. Thanks

Hi, millerna.

The new functionality for moving pages inside document has been added into new 2.5.211 build. The example code:

Code: Select all

pdfViewer.SetProperty("Operations.MovePages.RangeType", "Exact"); // supported values: "All", "Odd", "Even", "Exact"
pdfViewer.SetProperty("Operations.MovePages.RangeText", "1-20");
// pdfViewer.SetProperty("Operations.MovePages.RangeFilter", "All"); // supported values: "All", "Odd", "Even"
pdfViewer.SetProperty("Operations.MovePages.InsertBefore", 10); // insert before, zero-based index
pdfViewer.DoDocumentVerb(docID, "", "MovePages", stubObj, null, PXCVA_NoUI);

HTH
