Converting tables (in a PDF) to an image

Aspose.Total Product Family
#1
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

Hi Tital,


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

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 RenderingOptions property as following to fix the border width issue, it will help you to resolve the issue.

Document pdfDocument = new Document(@“Aspose
White Lines Issue.pdf”);<o:p></o:p>

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 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();

}

}
