ArgumentNullException from ved System.IO.BinaryReader

Aspose.PDF Product Family

Hi

I am trying to convert a jpeg file to PDF using code I copied from your web site (http://www.aspose.com/documentation/.net-components/aspose.pdf-for-.net/how-to-convert-an-image-to-pdf.html). There is one difference: I did not manage to find Aspose.Pdf.Generator.Pdf, so I used Aspose.Pdf.Pdf, which has the same methods.

When I call Save on the Pdf object, I get an exception from the System.IO.BinaryReader constructor, saying that parameter "input" is null.

What can I do about this?

I include the exception and my code.

Hi Klaus,

Thanks for using our products and sorry for replying you late.

Aspose.Pdf.Generator name space is available Aspose.Pdf for .NET versions starting with number 6.0.0. In fact its a new MergedAPI which contains the combined features of Aspose.Pdf for .NET (pre-6.x) and Aspose.Pdf.Kit for .NET. So now you can use the single component to create as well as manipulate existing PDF documents. Now concerning to your query, I am not entirely certain about the reasons why this issue is occurring. Can you please share the source image file so that we can test the scenario at our end. We apologize for your inconvenience.

Hi Klaus,

Thanks for sharing the resource file. I have tested the scenario while using Aspose.Pdf for .NET 6.3.0 and the code snippet shared below and I am unable to notice any problem. The image is properly being converted into PDF format. Please take a look over the resultant PDF that I have generated. In case you still face any problem, can you please share some details regarding your working environment i.e. OS version, VisualStudio version, Aspose.Pdf for .NET version etc.

[C#]


// load source image file
FileStream fs = new FileStream(“d:/pdftest/Klaus+Ole+Kristiansen.jpg”, FileMode.Open);
//Instantiate a Pdf object by calling its empty constructor
Aspose.Pdf.Generator.Pdf pdf1 = new Aspose.Pdf.Generator.Pdf();
//Create a section in the Pdf object
Aspose.Pdf.Generator.Section sec1 = pdf1.Sections.Add();
//Create an image object in the section
Aspose.Pdf.Generator.Image image1 = new Aspose.Pdf.Generator.Image(sec1);
//Add image object into the Paragraphs collection of the section
sec1.Paragraphs.Add(image1);
// Set the path of image file
// image1.ImageInfo.File = “d:/pdftest/Klaus+Ole+Kristiansen.jpg”;
image1.ImageInfo.ImageStream = fs;
//Set the type of image using ImageFileType enumeration
image1.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Jpeg;
//Save the Pdf
pdf1.Save(“d:\pdftest\ImagetoPDF-Exception.pdf”);
