I am trying to add an image (.png) to a prexisting powerpoint template.

this is the code that i'm using:

I keep getting an error on the last line.

---------------------------------------------------------------------------

string CustomerPowerPointPath = HttpContext.Current.Server.MapPath("~") + "\\Templates\\" + "PlanningTemplate.ppt";

string CustomerSnapShotPath = HttpContext.Current.Server.MapPath("~") + "\\Templates\\" + "test.png";

// create powerpoint object

Presentation objPresentation = new Presentation(CustomerPowerPointPath);

Picture objPicture = new Picture(objPresentation, CustomerSnapShotPath);

int count = objPresentation.Pictures.Count;

int objPictureID = objPresentation.Pictures.Add(objPicture);

count = objPresentation.Pictures.Count;

int pictureWidth = objPresentation.Pictures[count-1].Image.Width;

int pictureHeight = objPresentation.Pictures[count-1].Image.Height;

Slide objSlide = objPresentation.GetSlideByPosition(10);

int slideWidth = objSlide.Background.Width;

int slideHeight = objSlide.Background.Height;

int pictureFrameWidth = Convert.ToInt32(slideWidth/2 - pictureWidth/2);

int pictureFrameHeight = Convert.ToInt32(slideHeight/2 - pictureHeight/2);

PictureFrame objPictureFrame = objSlide.Shapes.AddPictureFrame(objPictureID, pictureFrameWidth, pictureFrameHeight, pictureWidth, pictureHeight);

HttpContext.Current.Response.ContentType = "application/vnd.ms-powerpoint";

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=demo.ppt");

HttpContext.Current.Response.Flush();

System.IO.Stream objStream = HttpContext.Current.Response.OutputStream;

objPresentation.Write(objStream);

HttpContext.Current.Response.End();

Probably Response.Flush() will be enough in your case.

this doesn't seem to work.

am i using the right code? can you please send me a small snippet that i can use to insert an image to an existing powerpoint presentation?

Try it without response stream. Just save it to disk and check result.

Presentation objPresentation = new Presentation(“PlanningTemplate.ppt”);
Picture objPicture = new Picture(objPresentation, “test.png”);

int objPictureID = objPresentation.Pictures.Add(objPicture);
int pictureWidth = objPicture.Image.Width;
int pictureHeight = objPicture.Image.Height;

Slide objSlide = objPresentation.GetSlideByPosition(1);
PictureFrame objPictureFrame =
objSlide.Shapes.AddPictureFrame(objPictureID, 500, 500, pictureWidth * 8, pictureHeight * 8);
objPresentation.Write(“result.ppt”);

this still doesn't seem to work.

can i please to talk to you or someone on your support team by phone? i am on a tight deadline and I cannot wait a hour or two between each response. I tried calling the support number, but I was unable to reach anyone. can you please leave a direct number at richardtirado.com.

Could you explain what you mean “doesn’t seem to work” ? What result you have? Exception?
Did you try to save presentation and open it with MS PowerPoint?

Check LiveSupport: Aspose Documentation
I will be available next 2 hours.

I need to add an image to a new slide in an existing powerpoint template.

Can i use this code in a business object? (test.cs)

// create powerpoint object

Presentation objPresentation = new Presentation(CustomerPowerPointPath);

Slide objSlide = objPresentation.AddEmptySlide();

Picture objPicture = new Picture(objPresentation, CustomerSnapShotPath);

int objPictureID = objPresentation.Pictures.Add(objPicture);

int pictureWidth = objPicture.Image.Width;

int pictureHeight = objPicture.Image.Height;

PictureFrame objPictureFrame = objSlide.Shapes.AddPictureFrame(objPictureID, 500, 500, pictureWidth * 8, pictureHeight * 8);

HttpContext.Current.Response.ContentType = "application/vnd.ms-powerpoint";

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=PlanningTemplate.ppt");

HttpContext.Current.Response.Flush();

System.IO.Stream objStream = HttpContext.Current.Response.OutputStream;

objPresentation.Write(objStream);

Yes, you can. But don’t forget to set corect position and size of PictureFrame.

In such cases google suggest granting ASP.NET account full access to Aspose.Slides.dll.
Another possible solution is delete everything in VSWebCache and rebuild you app.
