Converting tables (in a PDF) to an image

Aspose.Total Product Family

We are facing with a issue that our client has complained. They generated a sample presentation pdf from sample presentation ppt (see files attached). Using Apose.Net for pdf library, the pdf file was converted into images. When converting to an image, sometimes it adds a border to the table in the jpg image which is not present in the pdf file. Is there a way to remove the table borders

Thanks for your inquiry. I have converted your shared PDF to JPEG using latest version of Aspose.Pdf for .NET 10.4.0 and unable to notice the white border issue. Please download and try latest version of Aspose.Pdf for .NET version, it will resolve the issue.

Please feel free to contact us for any further assistance.

Hi Tital,


We have upgraded our libraries to the latest ones:
Aspose.PDF 10.5.1
Aspose.Slides 15.4.0

But we are still observing the same issue while converting pdf/pptx files to image set.
Could you please advise if this issue is going to be resolved?

Thank you in advance

Important Update:
I have analyzed the image you provided and noticed that white spaces are there as well.

Hi Tilal,


In the image you provided these white spaces are barely visible. I’m using in-built viewer for Crome v43.0.2357.81.

Hi there,

Thanks for your feedback. Please use the RenderingOptions property as shown below to fix the border width issue, which will help resolve the issue.

Document pdfDocument = new Document(@"Aspose White Lines Issue.pdf");

for (int pageCount = 1; pageCount <= pdfDocument.Pages.Count; pageCount++)
{
    using (FileStream
        imageStream = new FileStream(@"Aspose White Lines Issue_1" + pageCount + ".jpg", FileMode.Create))
    {
        // Create Resolution object
        Resolution
            resolution = new Resolution(300);

        // Create JPEG device with specified attributes (Width, Height, Resolution, Quality)
        // where Quality [0-100], 100 is Maximum
        JpegDevice
            jpegDevice = new JpegDevice(resolution, 100);

        // Set this property to eliminate the issue with incorrect width
        // (by default WidthExtraUnits = 0)
        jpegDevice.RenderingOptions = new RenderingOptions()
        {
            WidthExtraUnits = 0.2f
        };

        // Convert a particular page and save the image to stream
        jpegDevice.Process(pdfDocument.Pages[pageCount], imageStream);

        // Close stream
        imageStream.Close();
    }
}
