copy a slide into another slide in powerpoint presentation

hi

I want to copy a slide with its contents into another slide in powerpoint presentation using openXml format.

thanks

Hi,

Do you want to achieve this programatically?

You can copy the slide content, it's slide layout and the slide master. To create a new

slide, create slide part, slide layout and slide master part and dump the contents copied

into the corresponding parts.

These links may useful to you. Some of the samples were on beta versiob of Open XML. Change

the namespace and the relationship wherever required.

Hi,

If you want to add an entry into presentation.xml file, get the content of the file in xmldocument object, add details about slidemaster and slide  as

<p:sldMasterIdLst>
 <p:sldMasterId id="2147483648" r:id="rId1"/>
</p:sldMasterIdLst>
<p:sldIdLst>
 <p:sldId id="256" r:id="rId2"/>
</p:sldIdLst>

slide1.xml.rels file will get created when you link slide and the slide layout.

I have a sample to create a new presentationML document. This will give you the parts and the reationship details. I am using existing xml files rather than creating a new one.

Here is the sample code

     XmlDocument doc;
        List<string> Heading = new List<string>();//holds the contents of Slide Heading from the UI
        List<string> Body = new List<string>();//holds the contents of Slide Body from the UI
        int positionCount = 0;//holds the count of slides

        string docFileName = "";
        Uri default1 = null;

        //Declaration,Package
        Package package = null;
        PackageRelationship rel = null;
        Uri uri;
        Uri uriPart;
        PackagePart part;
        StreamWriter partWrt;
        PackagePart getPart;

        int slId = 256;//Id given to the slide 1 in the ppt,which goes on incrementing by 1 for every new slide added
        int relationId = 2;

        int resourceId = 0;
        //Declaration,Namespace
        string nameSpace = "http://schemas.openxmlformats.org/presentationml/2006/main";
        string nameSpaceDrawing = "http://schemas.openxmlformats.org/drawingml/2006/main";

hi sheela;

Thanks for your reply, but ia have a problem while copying the slide, The new slide is empty.

 Also the pptx file gave me an error while opening about corrupting in some of the slide components like "Text and Image... etc" .

Here is the code that i wrote

//Copying slide (1) into new slide (6):

XmlDocument doc = new XmlDocument();

doc.Load("c:\\slide1.xml");

uri = new Uri("/ppt/slides/slide6.xml", UriKind.RelativeOrAbsolute);

part = package.CreatePart(uri, "application/vnd.openxmlformats-officedocument.presentationml.slide+xml");

StreamWriter partWrt = new StreamWriter(part.GetStream(FileMode.Create, FileAccess.Write));

//Create the relationship file

uri = new Uri("/ppt/slides/slide6.xml", UriKind.Relative);

Uri uriPart = new Uri("/ppt/presentation.xml", UriKind.Relative);

PackagePart getPart = package.GetPart(uriPart);

// PackageRelationship

PackageRelationship rel = getPart.CreateRelationship(uri, TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/slide", "rId60");//

////3. Add slide master and slide layout as parts and set the relationship (slide inherits layout details from slidelayout and slidemaster)

uri = new Uri("/ppt/slideLayout6.xml", UriKind.Relative);

part = package.CreatePart(uri, "application/vnd.openxmlformats-officedocument.presentationml.slideLayout+xml");

partWrt = new StreamWriter(part.GetStream(FileMode.Create, FileAccess.ReadWrite));

doc = new XmlDocument();

doc.Load("c:\\slideLayout1.xml");

uri = new Uri("/ppt/slideMaster6.xml", UriKind.Relative);

part = package.CreatePart(uri, "application/vnd.openxmlformats-officedocument.presentationml.slideMaster+xml");

partWrt = new StreamWriter(part.GetStream(FileMode.Create, FileAccess.ReadWrite));

doc = new XmlDocument();

doc.Load("c:\\slideMaster1.xml");

//create relationship to the slidemaster

uri = new Uri("ppt/slideMaster6.xml", UriKind.Relative);

uriPart = new Uri("/ppt/presentation.xml", UriKind.Relative);

rel = getPart.CreateRelationship(uri, TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideMaster", "rId61");//

//create relationship to the slide layout

uri = new Uri("/ppt/slideLayout6.xml", UriKind.Relative);

uriPart = new Uri("/ppt/slideMaster6.xml", UriKind.Relative);

rel = getPart.CreateRelationship(uri, TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout", "rId62");//

//connect slide layout with the slide

// create a relationship from slide to slidelayout

uri = new Uri("/ppt/slideLayout6.xml", UriKind.Relative);

uriPart = new Uri("/ppt/slides/slide6.xml", UriKind.Relative);

rel = getPart.CreateRelationship(uri, TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout", "rId63");//

//create relationship from layout to master

uri = new Uri("/ppt/slideMaster6.xml", UriKind.Relative);

uriPart = new Uri("/ppt/slideLayout6.xml", UriKind.Relative);

rel = getPart.CreateRelationship(uri, TargetMode.Internal, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideMaster", "rId64");//

//modify the presentation.xml

XmlDocument xDoc = new XmlDocument(nt);

XmlNodeList sheetNodes = xDoc.SelectNodes("//p:sldIdLst/p:sldId", nsManager);

XmlElement x = (XmlElement)sheetNodes[0].CloneNode(true);

x.SetAttribute("id", "257");

x.SetAttribute("r:id", "rId3");

Hi1

How can I copy a Slide into another powerpoint presentation with use SDK like this?

Dim pptCre As PresentationDocument = PresentationDocument.Open("C:\Documents and Settings\CHT\My Documents\pptx\Test1.pptx", PresentationDocumentType.Presentation)

Hi,

As your question is slightly different from the discussion that was going on in this thread,please put your
question as a new question.

Mallika

Hi,

I guess Java Api doesn't do that.
But you can go through the documentation of openxml4j API.
