PngDevice does not convert pdf to a png image in a timely manner

I am using aspose pdf 7.2. When converting some pdfs to a png image, the PngDevice.Process does not convert the pdf in a timely manner, the processing takes over 4-5 minutes. Attached is the pdf that you can use to reproduce this issue

using Aspose.Pdf.Devices;
using (MemoryStream imageStream = new MemoryStream())
//create PNG device with specified attributes
//Width, Height, Resolution, Quality
//Quality [0-100], 100 is Maximum
//create Resolution object
imageStream.Position = 0;
Resolution resolution = new Resolution(300);
PngDevice pngDevice = new PngDevice(resolution);
//convert a particular page and save the image to stream
pngDevice.Process(pdfDocument.Pages[1], imageStream);

Hi Caroline,

Thanks for your interest in our products.

The link that you have shared above does not seem to be related to our products. However I would recommend you to please try our components for conversion of PDF pages to Image format. In case you encounter any issue, please share the resource file. Furthermore, the time taken by our component to transform PDF pages to Image format depends upon the structure and complexity of source PDF file.
