Converting Word To PDF: Image doesn't convert to pdf correctly

Aspose.Words Product Family

Hi,I’ve updated my version of Aspose Words to the latest version. Initially we were having size issues when converting word documents to PDF (some were growing to 10 times the size so a 7MB doc would convert to a 75 MB pdf).I’ve updated our code as so:

doc =new Document("C:\\Users\\Desktop\\Doc1.docx"); 
doc.UpdatePageLayout(); 
Aspose.Words.Saving.PdfSaveOptions pso = new Aspose.Words.Saving.PdfSaveOptions();
pso.UseCoreFonts = true;
pso.ImageCompression = Aspose.Words.Saving.PdfImageCompression.Jpeg;
pso.JpegQuality = 90;
doc.Save("C:\\Users\\Desktop\\Doc1.pdf", pso);

However when I convert the document, the image in the PDF appears with lines bordering it on certain sides. This does not occur if I set the image compression to ‘Auto’ instead of ‘Jpeg’. But in doing so the resulting PDF grows in size. Is there a way to keep the size down of the PDF and get a better image quality?
I’m attaching a sample document (its not the original) - but the image causing the issue is in it.
Thanks.

Hi Mercer,

Thanks for your patience. It is to inform
you that the issue which you are facing is actually not a bug in
Aspose.Words. The image is transparent which causes such side effect when it’s saved with Jpeg codec. Please use PdfSaveOptions.PreblendImages to true as shown in following code example. Hope this helps you.

Document doc = new Document(MyDir + "in.docx");
PdfSaveOptions options = new PdfSaveOptions();
options.UseCoreFonts = true;
options.ImageCompression = PdfImageCompression.Jpeg;
options.PreblendImages = true;
options.JpegQuality = 90;
doc.Save(MyDir + "Out.pdf", options);
