We have already tried increasing value of PdfOptions.SufficientResolution but to no avail, even if I set it to as high as 9600, quality is still same as if it was set to 128
This was tested in Win10, with following minimal sample code
Presentation presentation = new Presentation(input_file_full_path);
PdfOptions options = new PdfOptions();
options.JpegQuality = 100;
options.SufficientResolution = 128;
presentation.Save(output_file, SaveFormat.Pdf, options);
Attached are input/output files, it seems that issue actually only happens (or maybe only significantly noticeable) if image is rotated, see sample files below
@smljoju,
Thank you for the additional data.
I’ve reproduced the problem with the image quality in the generated PDF and added a ticket with ID SLIDESNET-43042 in our issue tracking system. We apologize for any inconvenience. Our development team will investigate this case. You will be notified when the issue is resolved.
