The attached pdf has two images. In the original the sharpness is excellent, in the image rendered on the viewer, it is not possible to read the content. It is not sufficiently clear.

@mlasarga,

The issue you have found earlier (filed as VIEWERNET-1508) has been fixed in this update. Furthermore, we have added a new setting to PdfOptions class named as ImageQuality. By default image quality is set to “Low” for best performance. However, you can control the quality as shown in the below code sample.

//Set high image quality
HtmlOptions htmlOptions = new HtmlOptions();
htmlOptions.PdfOptions.ImageQuality = ImageQuality.High;
 
//Render pages
List<PageHtml> pages = viewerHtmlHandler.GetPages(guid, htmlOptions);

Hi there.
Thanks for the update.
What about performance? is it affected with this change?

Best regards.

@mlasarga,

Thanks for coming back to us.

Yes, with the ImageQuality.Low value you’ll have the best performance and with ImageQuality.High value, you’ll have the best quality but it will slow down the rendering comparatively.
