Can the Presentation Builder be used without the USING() { } Statement?

YasiduY3K — Sat, 11 May 2013 22:59:33 GMT

Hi,

I've been trying out the presentation builder code, and what I am aiming is to, instead of having USING statement, to directly load presentations from PowerPoint files as memory streams, perform cloning and then save the changes back to memory streams. The target is to allow manipulation of the PowerPoint object, even after the cloning is done and save it back at the desired point.

But so far I've had only failure n this aspect.

Can this be done?

I will attach a code sample 'asap', with more clarifications.

Thanks,

Using Custom UI Editor if statement when file name is .pptx

y0gster — Thu, 09 May 2013 08:47:47 GMT

i just found this Custom UI Editor while searching for a way to have an onload event on Powerpoint. Now I need is an if statement in the UI editor that would prevent it from running when the file extension is pptx. Here is the line of code im using in customui:

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" 
onLoad="onLoadCode" >
</customUI>

I can write the code in vba but here in xml im totally lost. What I was thinking was something like this which I wrote in vba:

if right(filename,4) = "pptm" then
onLoad
="onLoadCode" 
end if

newMasterPart.SlideMaster.Preserve = false, is not working

YasiduY3K — Wed, 08 May 2013 11:37:26 GMT

I'm trying to use the Preserve attribute of Slide Master, in order to clear unreferenced Slide Masters.

My aim is to clone all slides in a presentation(has only one slide) to a base presentation(has only one slide) and change the layout of the cloned slides to the layout of the base presentation.

The approach I took was,

(Base presentation denoted as B, to be cloned presentation is denoted as C)

Copy the slide part of the slide of C into B.

Copy the master of the C into B.

Set the SlideMaster.Preserve attribute to false in newly copied master.

Delete existing layout parts of the newly added slides pars in B(cloned slides from C).

Add the required layout part from B to the newly added slide parts.

Traverse through LayoutId's and re order them to contain unique values.

But when I open the resultant file, although there are no reference to the MasterSlide copied from C. It still exists.

Note: Although i change the layout slide in the same code snippet, in practice it will be performed at a different execution path, hence not coping the MasterSlides of C is not an option.

Base Presentation (B)

Master Slide of Base

Clone presentation (C)

Master Slide of Clone presentation

Resultant Output

Master slides of Output

Although there is no references to the second master slide, it still prevails even after setting the preserve attribute to false.

A code sample is attaches as Post2.zip

How to group several Shapes into a GroupShape Object

denlar — Thu, 02 May 2013 07:46:54 GMT

Hello OpenXML Developers,

I am new to this forum , but I found a lot of usefull threads here yet.

Today i haven't found any answer to this question : How to build a GroupShape Object from several Shape objects ?

Using the productivity tool, I built have explored some GroupShapes Object :

groupShape1.Append(nonVisualGroupShapeProperties14);
groupShape1.Append(groupShapeProperties14);
groupShape1.Append(shape64);
groupShape1.Append(shape65);
groupShape1.Append(shape66);

But I am not able to build properly the GroupShape Object from Several shapes.

If anyone has a proper solution it would be great.

Thank you.

In the mean time I am trying and if i am sucessfull, i will give the answer here

Copy SlideMasterlayout element into the Slide

angelo.trozzo — Wed, 01 May 2013 10:52:01 GMT

Hi Guys,

I am new of this technology and I am trying to complete a task in OpenXML: Generate a single slide presentation from an existing one, coping the layout information from the master layout directly into the slide. The target is to have a destination presentation with an empty master layout and a Slide that still looks like the original one that was using the original Master Layout.

This means I have to find the relation between the Slide and the master in a presentation, understand what is defined in the Master and what at Slide lavel , copy all these properties like placeholders and theme from the Master to the layout.

I really need help, is already a couple of weeks that I am struggling but on the net I can find just really simple example of presentation manipulations. I found on this web site a really interesting video about using PresentationBuilder, but isstill not really enough and I have no access to any source code.

Thanks

Angelo

The presentation builder corrupts a presentation

YasiduY3K — Sat, 27 Apr 2013 05:40:03 GMT

Hi,

My aim is to clone all slides in a presentation to a base presentation and change the layout of the cloned slides to the layout of the base presentation.

The approach I took was,

(Base presentation denoted as B, to be cloned presentation is denoted as C)

Copy the slide parts of each slide of C into B.

Copy the masters of the B into C

Delete existing layout parts of the newly added slides pars in B(cloned slides from C).

Add the required layout part from B to the newly added slide parts.

Traverse through LayoutId's and re order them to contain unique values.

The result presentation is a corrupted output.

Then I did a bit more checking up and came across the presentation builder mentioned in http://openxmldeveloper.org/blog/b/openxmldeveloper/archive/2013/01/14/quick-introduction-to-presentationbuilder.aspx

The second option of the builder does what I'm after, although it clones both the slides into a new presentation as" Out2.pptx"

When I tried my files on it, it gives me the same corrupted message from PowerPoint.

I need to figure out on why it's happening and also how can I correct this?

Base presentation:

Clone presentation:

Error message:

Resulting output: (Out2.pptx)

1st slide gets corrupted!

The presentation builder code is attached as Post.zip

The attached try to clone both presentation documents to a new presentation document (built from scratch), but use the master and layouts of the first cloned presentation (base presentation) for all the slides.

Files in builder:

Companies.pptx (basepresentation)

Customer Content.pptx (clone presentation)

Out2.pptx (resulting presentation)

Removing images from a PPTX (and not breaking any relations)

duarte.aragao — Fri, 19 Apr 2013 12:10:25 GMT

Hi again!

How can I remove a file (like an image) from a PPTX without breaking any relation?

If i delete an image in a slide how do I confirm that there isn't anymore relations to that image? Do I have to go through all the relation files listed in [Content_Types].xml and confirm that the image that I want to delete is no referenced?

Media files can have any amount of relation references to it?

Thanks!

When to render text and when to inherent data from master and layout?

duarte.aragao — Mon, 08 Apr 2013 10:29:27 GMT

I am trying to parse the proper data from a slide.

There are properties (for example for a shape) that are inherited from the layout and master slide, but when should I render a shape? I know that, I probably should only render text in the shapes represented in the slide, and ignore the ones that are in the master and layout, right?

But if there is an image, even if that image is on the master or layout I should render it?

How does the inheritance system works? What should I render or not render when only displaying a slide?

Thanks

add Slides dynamically based on Number of Images

Gowtham.k — Tue, 02 Apr 2013 07:20:55 GMT

Hello every one, I have followed the below code to place images on PPT.

public static void PPTReplaceImageOnSlide(string fileName, string slideTitle, string imagePath)

{

try
{
const string presentationmlNamespace = "http://schemas.openxmlformats.org/presentationml/2006/main";
const string drawingmlNamespace = "http://schemas.openxmlformats.org/drawingml/2006/main";
const string relationshipNamespace = "http://schemas.openxmlformats.org/officeDocument/2006/relationships";
string FilePath = HttpContext.Current.Server.MapPath("~/PPtFile/Sample.pptx");
using (PresentationDocument pptPackage = PresentationDocument.Open(FilePath, true))
{
PresentationPart presentationPart = pptPackage.PresentationPart;
// Manage namespaces to perform Xml XPath queries.
NameTable nt = new NameTable();
XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
nsManager.AddNamespace("p", presentationmlNamespace);
nsManager.AddNamespace("a", drawingmlNamespace);
nsManager.AddNamespace("r", relationshipNamespace);
List slideParts = new List();
presentationPart.GetPartsOfType(slideParts);
presentationPart.AddNewPart("image/jpeg", "id1");
foreach (SlidePart slidePart in slideParts)
{
XmlDocument slideDoc = new XmlDocument(nt);
slideDoc.Load(slidePart.GetStream()); XmlNode titleNode = slideDoc.SelectSingleNode("//p:sp//p:ph[@type='title' or @type='ctrTitle']", nsManager);
if (titleNode != null)
{
string titleText = titleNode.ParentNode.ParentNode.ParentNode.InnerText;
if (string.Compare(titleText, "Image", true) == 0)
{
List imageParts = new List();
slidePart.GetPartsOfType(imageParts);
foreach (ImagePart imagePart in imageParts)
{ if (imagePart != null)
{
string oldRelID = slidePart.GetIdOfPart(imagePart);
string imageFile = Path.GetFileName(imagePath);
Uri newImageUri = new Uri("/ppt/media/" + imageFile, UriKind.Relative);
ImagePart newImagePart = slidePart.AddImagePart(ImagePartType.Jpeg);
using (Stream outputStream = newImagePart.GetStream())
{
using (FileStream inputStream = new FileStream(imagePath, FileMode.Open, FileAccess.Read))
{
int len = Convert.ToInt32(inputStream.Length);
byte[] bytes = new byte[len];
int bytesRead = inputStream.Read(bytes, 0, len);
if (bytesRead == len)
{
outputStream.Write(bytes, 0, len);
}
}
}
string searchString = string.Format("//p:pic//a:blip[@r:embed='{0}']", oldRelID);
XmlNode relNode = slideDoc.SelectSingleNode(searchString, nsManager);
if (relNode != null)
{
relNode.Attributes["r:embed"].Value = slidePart.GetIdOfPart(newImagePart);
}
slidePart.DeletePart(imagePart); break;
}
}
slideDoc.Save(slidePart.GetStream());
break;
}
}
}
}
}
catch (Exception ex)
{
throw ex;
}
}

Every thing is working fine , it is adding an image to the slide, now i want to add images dynamically and also the number of slides, presently it has only one slide it is displaying one image. Sorry for my bad english, Thanks in advance.

lumMod and lumOff color modifications

snugpants — Tue, 19 Mar 2013 21:57:18 GMT

I just started a project converting ooxml Powerpoint presentations to a proprietary format. I've gotten a lot of useful information from other forum posts about correctly calculating the various color mods that are available but still have a couple of questions.

1.) Is it possible to have a <a:lumOff> without a corresponding <a:lumMod>? This goes for the other mod and off tags as well. I haven't been able to produce any examples with just a <a:lumOff> tag.

2.) More generally, I'm having a hard time creating test documents for some of these modifications. Specifically tint and shade. Does anybody have any advice for how to generate pptx files with tint/shade? I suppose I could hand-alter the xml and re-package it - but I'm looking for something more authentic.

How to bind data to a existing table in powerpoint using open xml

dineshharaveer — Wed, 13 Mar 2013 09:05:34 GMT

Hi All,

I using openxml to create a powerpoint from an web app.I created a ppt with charts and opened openxml sdk productivity tool and code was generated with that i modified the chart data which is coming from database,Code for which i created to modify the chart data as

created a class for the code in the sdk,in that CreatePart() i added these links

ChartPart chartPart1 = slidePart1.AddNewPart<ChartPart>("rId3");
            GenerateChartPart1Content(chartPart1);
           // This is below code added
            #if true    // Injects the chart part modification process
                        var chartModifier1 = new ChartPartModifier();
                        chartModifier1.UpdateSecondChartPart(chartPart1);
            #endif

            EmbeddedPackagePart embeddedPackagePart1 = chartPart1.AddNewPart<EmbeddedPackagePart>("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "rId2");
            GenerateEmbeddedPackagePart1Content(embeddedPackagePart1);

and created a class for ChartPartModifier()

public void UpdateSecondChartPart(ChartPart chartPart)
        {
            // Searchs SeriesText and its Values to replace them with your dynamic data
            var seriesLabels = chartPart.ChartSpace.Descendants<SeriesText>().ToList();
            var seriesValues = chartPart.ChartSpace.Descendants<Values>().ToList();
            var categoryAxis = chartPart.ChartSpace.Descendants<CategoryAxisData>().ToList();

            for (int i = 0; i < this._lineSecCharts.Count; ++i)
            {
                var yourLine = this._lineSecCharts[i];

                var label = seriesLabels[i].Descendants<NumericValue>().FirstOrDefault();
                var values = seriesValues[i].Descendants<NumericValue>().ToList();
                var categories = categoryAxis[i].Descendants<NumericValue>().ToList();

                // Replaces the label of the series
                label.Text = yourLine.Label;
                // Replaces the values of the series
                for (int valIdx = 0; valIdx < values.Count(); ++valIdx)
                {
                    values[valIdx].Text = yourLine.Plots[valIdx].Value.ToString();
                    categories[valIdx].Text = yourLine.Plots[valIdx].Category;
                }
            }
        }

Like this is there any way to modify the data in the table

Binding Data from DB to Powerpoint Chart using OpenXml in Asp.Net

dineshharaveer — Tue, 12 Mar 2013 06:16:03 GMT

Hi All,

As i was new to OpenXML,i have seen some of the videos posted in the youtube,from those examples i have tried to save the ppt i was successfully done which i have copied the code from the openxml sdk v2.0 productivity tool which i have opened an created ppt file contains a chart in that. Upto now the code runs fine but i tried to implement to get the dynamic data from db which i tried in two ways. FIrstly, i without using any array the data in the x-axis is showing only the lastly binded data. Secondly i have tried using object collection array it throws an error "Object is not set to an instance".The code which i have written in the asp.net page.

Javascript libraries

duarte.aragao — Fri, 08 Mar 2013 17:45:08 GMT

Hello,

First, this site is amazing and I have been able to do something with OpenXML because of it, so thank you.

I am developing a small (and very modest) interface for Powerpoint OpenXML documents using only javascript (nodejs). I'm mostly interested in viewing and modifying PPTXs. I am using the ltxml library, which is a big help for handling the XML, but I am wondering if exists some library which would allow me to develop this at a higher level, something similar to the Apache.POI library but for js.

Anyone also doing stuff with js and openxml? Any good articles that you recommend?

I was already able to inspire myself in the C# code for string replacement on templates(http://openxmldeveloper.org/blog/b/openxmldeveloper/archive/2011/06/13/open-xml-presentation-generation-using-a-template-presentation.aspx), and make my version on JS, but I have a felling that, that is the most simple part, transforming a pptx to html is looking very hard. Any pointers and help is welcome.

Thanks

After editing, how to save as pptx file with different name at different location using OpenXml?

Thanks in advance.

Replacing all occurrences of one font with a different font

JohnP — Mon, 18 Feb 2013 02:58:55 GMT

Hello everyone,

I am very new to Open XML development, and am looking forward to learning more. However, I would be interested in hearing the community members’ thoughts on the programmatic challenge I am currently facing. I’d like to know if a solution would even be possible through an Open XML implementation.

My goal is to create a tool that can take any existing PPTX file, and create a new copy of the file where a particular font has been replaced with different font. For example, swapping “Times New Roman” with “Arial” – the actual fonts in question are proprietary but I’m hoping that won’t make a difference. Furthermore, the requirement specifies that all existing content be updated – that is, slides, masters, layouts, charts, tables, SmartArt, embedded Excel and Word tables, absolutely everything – and the font size and formatting of the affected text (i.e., bold, italic, etc) must remain intact . However, I suspect that for embedded objects, the emf would need to be replaced with a temporary “double-click to update” image.

Now a VSTO implementation was ruled out, mainly due to the embedded object requirement – programmatically opening every single object was deemed too risky. So I’m now attempting to learn if an Open XML solution would even be viable. I’d be very interested in hearing the thoughts of more experienced Open XML developers.

Thanks,
John

Accessing ActivePresentation object with OpenXML

peatpeat — Mon, 29 Oct 2012 16:25:32 GMT

Hi,

I'm working on a powerpoint plugin, so we need to be able to access the ActivePresentation's XML. I know there are various functions to deal with shapes etc. with the native ActivePresentation interface, but I need lower-level serialisation. Right now I'm resorting to outputting the PPTX file and opening the parts using System.IO.Packaging, but I can't seem to figure out a way to access the ActivePresentation directly, as Open() and Create() do not apply. Any method that could get an active slide's XML or insert a file into an open presentation would be a god-send!

Any pearls of wisdom? Thanks in advance!

Copy VB code of one Marco enabled document to another macro enabled document

            using (PresentationDocument myDoc = PresentationDocument.Open(templateDocumentFile, true))
            {
                VbaProjectPart vbaPart = FindPart(myDoc);
                AddCustomVBAPart(convertDocumentFile, vbaPart);
            }
        }
        //--------------------------------------------------------------------------
        private static VbaProjectPart FindPart(PresentationDocument mainPart)
        {
            if (mainPart != null)

Copy slide only without its master to another presentation

Penrose — Thu, 04 Oct 2012 01:41:37 GMT

I am merging several slides together and I have been successful in doing that but the resulting slide has got all the masters of the several slides am merging together. Meaning if I merge hundred slides I end up with a hundred slide masters and layouts. Is there a way to copy only the side and its information so that it inherits the destination slide's master and theme. Any help will be greatly appreciated. Am using the following code I got from microsoft website

static void MergeSlides(string presentationFolder, string sourcePresentation, string destPresentation)
    {
        int id = 0;

        // Open the destination presentation.
        using (PresentationDocument myDestDeck = PresentationDocument.Open(presentationFolder + destPresentation, true))
        {
            PresentationPart destPresPart = myDestDeck.PresentationPart;

            // If the merged presentation doesn't have a SlideIdList element yet then add it.
            if (destPresPart.Presentation.SlideIdList == null)
                destPresPart.Presentation.SlideIdList = new SlideIdList();

            // Open the source presentation. This will throw an exception if the source presentation does not exist.
            using (PresentationDocument mySourceDeck = PresentationDocument.Open(presentationFolder + sourcePresentation, false))
            {
                PresentationPart sourcePresPart = mySourceDeck.PresentationPart;

                // Get unique ids for the slide master and slide lists for use later.
                uniqueId = GetMaxSlideMasterId(destPresPart.Presentation.SlideMasterIdList);
                uint maxSlideId = GetMaxSlideId(destPresPart.Presentation.SlideIdList);

                // Copy each slide in the source presentation in order to the destination presentation.
                foreach (SlideId slideId in sourcePresPart.Presentation.SlideIdList)
                {
                    SlidePart sp;
                    SlidePart destSp;
                    SlideMasterPart destMasterPart;
                    string relId;
                    SlideMasterId newSlideMasterId;
                    SlideId newSlideId;

                    // Create a unique relationship id.
                    id++;
                    sp = (SlidePart)sourcePresPart.GetPartById(slideId.RelationshipId);
                    //relId = sourcePresentation.Remove(sourcePresentation.IndexOf('.')) + id;
                    relId = "runtId" + id++;
                    // Add the slide part to the destination presentation.
                    destSp = destPresPart.AddPart<SlidePart>(sp, relId);

                    // The master part was added. Make sure the relationship is in place.
                    destMasterPart = destSp.SlideLayoutPart.SlideMasterPart;
                    destPresPart.AddPart(destMasterPart);

                    // Add slide master to slide master list.
                    uniqueId++;
                    newSlideMasterId = new SlideMasterId();

Generating native, editable .pptx file with tables/charts created in web app built with Javascript/HTML/CSS/JSON front-end

blueliner — Wed, 29 Aug 2012 23:54:23 GMT

I am building a web app where I need to be able to provide the user with the ability to do the following:

1) User will generate tables and charts created in front-end screens built with Javascript/HTML/CSS which generates a JSON object (this is already built).

2) Once the user has the table/chart configured, provide them with the ability to drag and drop the tables/charts generated in the the web app into a widget that will display thumbnails of slides with the tables/charts so they can build a PowerPoint presentation. (need a solution for this)

3) Once they have the slides they want with the tables/charts, need to provide them with the ability to convert the slides into a native, editable .pptx format and export the .pptx file to save on their hard drive or on the server that they can open and edit within PowerPoint. (need a solution for this).

I have researched this and found Apache POI and Aspose but from the information I found neither solution can provide the above functionality. I would appreciate any suggestions on possible solutions (ideally open source if available) and/or if there aren't any currently available I would appreciate advice/suggestions on the simplest and fastest way to develop this from any developers with experience in this area.

Thanks very much.
