Blurry word document render in Image based rendering



I don’t believe the issue with blurry document raised in v3.2.0 version is still fixed.
unfortunately i am able to replicate this.
the earlier Ticket raised against it is
<span style=“color: rgb(76, 82, 89); font-family: “Times New Roman”, serif; font-size: 13.3333px; line-height: 18px; text-indent: -24px; background-color: rgb(221, 221, 221);”>VIEWERNET-479 - Blurry document in Image Based rendering Post

The suggestion mentioned that setting quality of imageOption would fix issue is not working for us.
I am using Quality = 100 and Type = JPEG.

all issues are replicate through sample solution of groupdocs.

Hi Puneet,

Thanks for being patient.

I have investigated your issue at my end and tested JpegQuality feature with different values. I did testing in both browsers, Chrome and IE11. In my case image quality is working properly. I have attached output of my testing in Chrome and IE11. Furthermore, please remove browser’s cached files and images and the cache (temp/cache folder) of viewer as well and try again. I am using following Javascript parameters.

filePath: ‘demo.docx’,
zoomToFitWidth: true,
showFolderBrowser: true,
showThumbnails: true,
showZoom: true,
showHeader: true,
showPaging: true,
width: 650,
height: 900,
// watermarkPosition: ‘Diagonal’,
//watermarkText: ‘全角’,
//watermarkWidth: 10,
useHtmlBasedEngine: false,
showDownload: true,
downloadPdfFile: false,
showPrint: true,
usePdfPrinting: false

And for JpegQuality, I am using ImageOptions in GetDocumentPageImage.aspx.cs file as below:

var imageOptions = new ImageOptions
ConvertImageFileType = ConvertImageFileType.JPG,
Watermark = Utils.GetWatermark(parameters.WatermarkText, parameters.WatermarkColor,
parameters.WatermarkPosition, parameters.WatermarkWidth),
Transformations = parameters.Rotate ? Transformation.Rotate : Transformation.None

Please check these settings at your end and give us your feedback.

Warm Regards
