I am trying to add an image to the word document using dotnet core and Open SDK library. Followed the exact same instruction as per the MSDN article. The code runs ok, but while trying to open document its says the document is corrupted.
Microsoft Doc
Used the OpenSDK Productivity tool and validated the document. Showing this error
Have confirmed that the Image Type are same. Not able to understand whats wrong.

I have a cross platform app which I need to show a set of images when the user clic in a button, so, I put these image files named as "img000.png" to "img029.png" in a folder in the PCL solution and make al these images as "EmbeddedResource", after,I fill a List with all these images and its work fine at now, i.e. the image is shown like I want, but when I click in the button to show the next image in the list the image don't go to the next.

but the image don't change, i.e. change, like I see in debug, but don't show in the Layout when I click in the buttons.
Maybe I'm doing it wrong.
Can someone here help me?
thanks in advance
I'm trying to insert a signature image in a Word document created by a standard-letter generating application. I am using code adapted from various examples found on the web (see below). The application inserts the image, and the space in the document occupied by it is correct, but the image itself is not displayed.
I have tried it with both .png and .jpg images, but neither work; it doesn't appear to be a problem with the image itself.
I have examined the document using the OpenXml SDK Tool, which shows that the image is correctly embedded and encoded as a Base64 data string.
The problem that the SDK Tool does identify is that, compared to a document in which an image is manually inserted (and is correctly displayed), the pic:pic element in the document is rendered with the wrong namespace (a:pic) and it and all child controls are rendered as OpenXmlUnknownElement (see screenshot below).
Can anyone please tell me what is causing the incorrect namespace / element, and how to fix the problem?

this issue stressed me up some hours and finally I found the reason. That's because the Drawing element Id need to be unique, you can't fix the ID like this
new DW.DocProperties() { Id = 1U, Name = "Picture 1" }
In my case, I have this function to set alt text and update the Id as well:
private static HashSet<uint> _drawingElementIds = new HashSet<uint>();
public static void SetPictureAltText(OpenXmlElement imageContainer, string altText)
{
var docPro = imageContainer.Descendants<DocProperties>().FirstOrDefault();
if (docPro != null)
{
//Make sure new image has unique ID, otherwise some images won't display
var newId = (uint)new Random().Next(10, 10000);
while (_drawingElementIds.Contains(newId))
{
newId = (uint)new Random().Next(10, 10000);
}
_drawingElementIds.Add(newId);
docPro.Id = new UInt32Value(newId);
docPro.Description = altText;
}
}
Cheers,

Watch your namespaces! I'm guessing you've copied from the same source as I did (which I'm sure was the Microsoft documentation), however the namespaces appear to be wrong in it for the following two properties:
A.BlipFill -> PIC.BlipFill
A.ShapeProperties -> PIC.ShapeProperties
Full code below:
var element = new Drawing(
new DW.Inline(
new DW.Extent()
{
Cx = 5657850L,
Cy = 3771900L
},
new DW.EffectExtent() { LeftEdge = 0L, TopEdge = 0L, RightEdge = 0L, BottomEdge = 0L },
new DW.DocProperties() { Id = 1U, Name = "Picture 1" },
new DW.NonVisualGraphicFrameDrawingProperties(new A.GraphicFrameLocks() { NoChangeAspect = true, NoResize = true, NoSelection = true }),
new A.Graphic(new A.GraphicData(new PIC.Picture(
new PIC.NonVisualPictureProperties(
new PIC.NonVisualDrawingProperties()
{
Id = 0U,
Name = "image.png"
},
new PIC.NonVisualPictureDrawingProperties()),
new PIC.BlipFill(
new A.Blip(
new A.BlipExtensionList(
new A.BlipExtension()
{

I am trying to generate a PowerPoint file containing a image using OpenXML. Unfortunately it does not work. The image is not being displayed. I've checked the file generated with the OpenXML productivity tool and I respectively unzipped the file contents. The file itself contains the image in /ppt/media/image.png and it should be displayed in the second slide.
Here's my code:
private void InsertSlide(string chartString, int position, string title, string text = "")
{
if (m_presentation == null || title == null || m_presentation.PresentationPart == null)
return;
var slide = new Slide(new CommonSlideData(new ShapeTree()));
var nonVisualProperties =
slide.CommonSlideData.ShapeTree.AppendChild(new NonVisualGroupShapeProperties());
nonVisualProperties.NonVisualDrawingProperties = new NonVisualDrawingProperties { Id = 1, Name = "" };
nonVisualProperties.NonVisualGroupShapeDrawingProperties = new NonVisualGroupShapeDrawingProperties();
nonVisualProperties.ApplicationNonVisualDrawingProperties = new ApplicationNonVisualDrawingProperties();
slide.CommonSlideData.ShapeTree.AppendChild(new GroupShapeProperties());
var slidePart = m_presentation.PresentationPart.AddNewPart<SlidePart>();
var imagePart = slidePart.AddImagePart(ImagePartType.Png, "irgendeinscheiss");
//var imageStream = new MemoryStream(Convert.FromBase64String(chartString));
using (var imageStream = new FileStream(#"C:\Users\DA\Desktop\Charts\1_Chart2_01.png", FileMode.Open))
{
imageStream.Position = 0;
imagePart.FeedData(imageStream);
}
slide.Save(slidePart);
var slideIdList = m_presentation.PresentationPart.Presentation.SlideIdList;
uint maxSlideId = 1;
SlideId prevSlideId = null;
foreach (SlideId slideId in slideIdList.ChildElements)
{
if (slideId.Id > maxSlideId)
maxSlideId = slideId.Id;
position--;
if (position == 0)
prevSlideId = slideId;
}
maxSlideId++;
SlidePart lastSlidePart;
if (prevSlideId != null)
lastSlidePart = (SlidePart)m_presentation.PresentationPart.GetPartById(prevSlideId.RelationshipId);
else
lastSlidePart = (SlidePart)m_presentation.PresentationPart.GetPartById(((SlideId)(slideIdList.ChildElements[0])).RelationshipId);
if (lastSlidePart.SlideLayoutPart != null)
slidePart.AddPart(lastSlidePart.SlideLayoutPart);
var newSlideId = slideIdList.InsertAfter(new SlideId(), prevSlideId);
newSlideId.Id = maxSlideId;
newSlideId.RelationshipId = m_presentation.PresentationPart.GetIdOfPart(slidePart);
m_presentation.PresentationPart.Presentation.Save();
}
Am I missing something? Maybe the relationships? After looking up 232243 thousand different examples, I am still stuck at this point. Thank you!
I think you need to add the image into the slide.CommonSlideData

I got it right now.
I am using
try
{
ISheet sheet = templateWorkbook.GetSheet(sheetName);
HSSFPatriarch patriarch = (HSSFPatriarch)sheet.CreateDrawingPatriarch();
//create the anchor
HSSFClientAnchor anchor;
anchor = new HSSFClientAnchor(0, 0, 255, 255,
start.Col, start.Row, end.Col, end.Row);
anchor.AnchorType = 2;
patriarch.CreatePicture(anchor,
LoadImage(imagePath, templateWorkbook));
}
catch (IOException ioe)
{
}
and LoadImage() method which returns path from the server.
Use this one. It runs fine.
I got the code for the Table in the powerpoint using the code generator, but I am not able to add the table to an existing powerpoint document.
I tried adding another table to the intended slide and doing the following:
Table table = slidePart.Slide.Descendants<Table>().First();
table.RemoveAllChildren();
Table createdTable = CreateTable();
foreach (OpenXmlElement childElement in createdTable.ChildElements)
{
table.AppendChild(childElement.CloneNode(true));
}
But that didn't work.
I am out of ideas on this issue.
My original target is to add a table with dynamic number of columns and fixed number of row to my presentation.
I know its been very long since this question is posted, but just in case if some one needs a working code to create table in pptx.
