Hi Umar


Thanks for your response and for your effort to logged this issue.

The solution you shared initially running on Image based rendering.
the issue with image based rendering is other than images all documents render blurry.

When i changed the rendering mode from image based to html based, i have to face again the same issue.

Please prefer the below setting in your shared solution and try again.
$(function () {
$(’#divDocumentViewer’).groupdocsViewer({
filePath: fileName,
zoomToFitWidth: true,
showFolderBrowser: true,
ShowSearch: true,
showHeader: true,
showPaging: true,
showThumbnails: true,
BackgroundColor: ‘gray’,
showZoom: true,
width: 850,
height: 1000,
IsPrintable: true,
useHtmlBasedEngine: true,
UseInnerThumbnails: true,
showDownload: true,
downloadPdfFile: true,
showPrint: true,
usePdfPrinting: true
});
});

Thanks
