Changing the quality of the images in a pdf.

[Simon]

I'm trying to shrink the size of a pdf that contains a lot of bitmaps with the following code:


        foreach (var page in pdf.Pages.Cast<PdfPage>())
                {                   
                    foreach (var imageInfo in page.ImagesInfo)
                    {
                        var image = imageInfo.Image;
                        var pdfBitmap = new PdfBitmap(image);
                        pdfBitmap.Quality = 80;
                        page.ReplaceImage(imageInfo.Index, pdfBitmap);
                    }
                }

But this doesn't seem to have any effect.

When I try to do this I lose the transparency from my images.

How can I reduce the image quality and keep the image transparency?

It also only appears to work on the first image. Only one image per page is replaced with a reduced quality image.

Thanks.
