PsDocument.SaveAsPDF results in huge file sizes

Aspose.Page Product Family
1

Hi there,

I am evaluating Aspose.Page for conversion of EPS to PDF. Getting it working was fairly simple.

However, the resulting PDF is huge. I believe it is not compressing any images at all within the PDF.

  • Original EPS file = 48kB
  • Convert and save to PDF using Ghostscript = 41kB in less than 1 second
  • Convert and save to PDF using Aspose.Page = 700kB in around 5 seconds

Changing the JpegQualityLevel of the PdfSaveOptions passed in to PsDocument.SaveAsPDF has no effect. I tried 0, 50, 80, 100 and all result in exactly the same output file.

I have attached a sample EPS file - just a few vectors and one image. There are no fonts/text in the EPS.
test.eps.zip (35.1 KB)

This code may not run OOTB but it’s a quick summary of my approach:

FileStream inputStream = new FileStream(inputFileName, FileMode.Open, FileAccess.Read);
PsDocument document = new PsDocument(inputStream);

PdfSaveOptions options = new PdfSaveOptions(true);
options.JpegQualityLevel = 0;

document.SaveAsPdf(outputFileName, options);

Hope you can help!
Peter
