New Post: ToBase64 is always different for same image

thanks for your reply

As you suggested the culprit is reading of PDF file.
Time taken to Read the PDF in milliseconds :3291
Time taken to Resize image in milliseconds :1268

If I get PDF outputted with 600 DPI, can I assume, the resize operation for 853640 and 14401080, maintaining the aspect ration of 4:3, we will not get any degradation in quality of image
IF I change the way to read the PDF to

images.Read(pdfDocumentInBytes); without using settings

instead of
images.Read(pdfDocumentInBytes, settings);
