Copy picture from one presentation to another

Hello,

I am trying to copy a picture from one presentation to another. I have a presentation with just one image in it (PresentationImage.ppt) that I am trying to copy. After I open the written presentation the wrong image appears in the upper left hand corner. The following is the code I am using:

Presentation imagePres = new Presentation(projectPath + “\PresentationImage.ppt”);

Aspose.Slides.Picture pic = imagePres.Pictures[0];

int picID = newPres.Pictures.Add(pic);

titleSlide.Shapes.AddPictureFrame(picID, 0, 0, 300, 300);

The following works for importing an image but I would rather copy the image from an existing presentation:

Aspose.Slides.Picture pic = new Aspose.Slides.Picture(newPres, projectPath + “\PresentationImage.jpg”);

int picID = newPres.Pictures.Add(pic);

titleSlide.Shapes.AddPictureFrame(picID, 0, 0, 300, 300);

Is there something else I need to do before copying the image from the presentation?

Thank you

Hi,

You should first write a Picture to stream using Picture.Write method. Then you should create a new picture from that stream and adds into the target presentation’s Pictures collection and gets its picture id. Finally you should add a picture frame with new picture id you got in the previous step.

e.g

Picture sourcePic=sourcePres.Pictures[0];

//Write it to stream

MemoryStream ms=new MemoryStream();

sourcePic.Write(ms);

ms.Position=0;

//Create target picture and add it to target presentation

Picture targetPic=new Picture(targetPres, ms);

int picID = targetPres.Pictures.Add(pic);

//Add a picture frame to target slide

targetSlide.Shapes.AddPictureFrame(picID, 0, 0, 300, 300);

Thank you very much. That worked great.
