There is an error when converting EMF or WMF image to PDF

I am planning to update Aspose.Pdf to latest release version 18.6.0. But there is an error occurred when i’m trying to convert EMF or WMF image to pdf.
assets:EMFandWMF.zip (5.1 MB)

Exception caught when trying to save pdf file.
Exception Message: “Parameter is not valid.”

There is no problem in Aspose.Pdf when converting these two images.


Thanks for contacting support.

We have tested the scenario in our environment and observed that API was able to generate PDF from EMF image. For your reference, an output PDF document along with used code snippet is also attached.

var pdf = new Aspose.Pdf.Document();
var pdfImageSection = pdf.Pages.Add();
FileStream stream = new FileStream(dataDir + "9068096883_283cba4f47_b.emf", FileMode.Open);
var image = new Aspose.Pdf.Image { ImageStream = stream };
image.IsApplyResolution = true;
pdfImageSection.PageInfo.Margin.Left = pdfImageSection.PageInfo.Margin.Right = pdfImageSection.PageInfo.Margin.Top = pdfImageSection.PageInfo.Margin.Bottom = 0f;
pdf.Save(dataDir + "testimage.pdf");

While adding your WMF file, using same code snippet, we have noticed that API generated an empty PDF document. Therefore, we have logged this issue as PDFNET-44962 in our issue tracking system. We will further look into details of the issue and keep you posted with the status of its correction. Please be patient and spare us little time.

We are sorry for the inconvenience.

Thanks for your reply. Now we are able to generate PDF from EMF.

Btw, do you have any plan when the fix of WMF will be released?
