hi

i'm adding images to my pdf using migradoc, so it becomes big in file size.

Is there a way to set pdf compression at highest level?

if I do this, are images still good quality?

thx

PDFsharp only applies lossless compression, so image quality does not change.
If files are too big it is up to you to shrink the images, thus you have full control over the image quality losses.

Hi

I found some information about compression options in migradoc here: http://developer.th-soft.com/developer/ ... n-options/

The code used there is:

Code:
PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(true);
pdfRenderer.PdfDocument = new PdfDocument();
pdfRenderer.PdfDocument.Options.FlateEncodeMode = PdfFlateEncodeMode.BestCompression;


"PdfDocument" is used, but in the code example of migradoc they are using "Document" as in following code line:

Code:
PdfDocumentRenderer renderer = new PdfDocumentRenderer(true, PdfSharp.Pdf.PdfFontEmbedding.Always);
renderer.Document = document;


What is the difference between "PdfDocument" and "Document" ?

If I use "Document" , can I still use the compression setting that's is applied to the "PdfDocument"?

I tried it, and my PDF file got a bit smaller.

PdfDocument is the PDF document created by PDFsharp. Document is the MigraDoc document. The former is the output of PdfRenderer, the latter is the input.
