Error adding Image to a PDF

Aspose.Slides Product Family

I am trying to add an image to a web app version of Aspose.Slides.

1) Is it possible to use relative URLs

2) I am getting the following error when trying to add image (and the path is correct):
The error is listed first, the complete code follows…

Could not find file ‘D:\3800-00879.jpg’. 

        <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">

Hi Julie,

I have observed the code snippet shared by you and it seems fine. The stack trace that you have shared suggests that the image file is not present in the destination drive and that is why file not found exception is raised. I have incorporated your code for addition of image in my project and it worked perfectly fine. I suspect that even if the image file is present in your destination driver, its extension will be probably .JPEG and you are accessing .JPG. I have shared the image file that I used for my testing as well.

Thanks and Regards,

Thank you, I was able to get the image to load in the PDF

However, can you answer question #1:

Can I reference the picture like:
Picture pic = new Picture(pres, @“Images\38000-00879.jpg”);

Instead of:
Picture pic = new Picture(pres, @“d:\website_root\images\38000-00879.jpg”);

Thank you

Hi Julie,

When working with web server you will actually be using virtual paths and setting the relative paths as in case of normal C# application may not prove fruitful. Please read this article and set that path accordingly by using the option that suits you:
http://devtoolshed.com/content/fixing-relative-paths-c-aspnet-when-using-url-rewriting
For instance you may use the following code snippet for accessing the application image path.

string outputDir = AppDomain.CurrentDomain.BaseDirectory+“\Image\38000-00879.jpg”;

Picture pic = new Picture(ExportPpt, outputDir );

Thanks and Regards,
