DPI issue in generated PDF

Aspose.Words Product Family

Hi,

I like to convert my word to pdf. While saving as PDF is it a way to save in particular dpi. eg save in 600 dpi. However after converting to pdf the quality is not good. We are using following code.

// Start MS word application 
wordDoc = OpenWordDoc(ref spoolFilePath);
// save Document as PDF
if (wordDoc != null)
{
    wordDoc.Activate();
    object fileFormat = WdSaveFormat.wdFormatPDF;
    object oPdfFilePath = Convert.ChangeType(pdfFilePath, typeof(object));
    // C# doesn't have optional arguments so we'll need a dummy value object 
    oMissing = System.Reflection.Missing.Value;
    wordDoc.SaveAs(ref oPdfFilePath, ref fileFormat, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
}

Many Thanks,

Hi Tahir manzoor,

Thanks For the reply. Please clarify my below doubts.

  1. Till what DPI its supported? If i don’t specify what is the default resolution?

  2. If the resolution of the image in the doc(word doc) is more than the one we are setting, what resolution it would be in the PDF?

  3. Is it supported only for Doc or the support is for PPT as well?

Hi Mathan,

2. If the resolution of the image in the
doc(word doc) is more than the one we are setting, what resolution it
would be in the PDF?

DownsampleOptions.Resolution property specifies the resolution in pixels per inch which the images should be downsampled to. The default value is 220 ppi.

DownsampleOptions.DownsampleImages property specifies whether images should be downsampled. The default value is true.

DownsampleOptions.ResolutionThreshold property specifies the threshold resolution in pixels per inch. If resolution of an image in the document is less than threshold value, the downsampling algorithm will not be applied. A value of 0 means the threshold check is not used and all images that can be reduced in size are downsampled. The default value is 0.
