Question:
How to increase the Rendering Quality in Web Clients?

Solution:
For Office documents, you can switch to Rendering Toolkit (Aspose), which is enabled by default starting with 6.10:
See: How do I enable the Aspose rendering engine?

For PDF Documents, you can update the appropriate Rendering Toolkit library:

Generally, when displaying documents in Web Client, we are trying to produce images with enough pixels to provide good quality and, at the same time, are small enough (bytes) to save CPU and bandwidth. It is possible to increase the rendering quality but bear in mind this will require more CPU power and bandwidth.
If you want to tweak the rendering settings perform the following steps:

  1. End all Imaging.Worker.exe processes in the task manager on the (web) server.
  2. Clear browser cache in the browser.
  3. Edit the file
    in 6.x Versions: C:\Program Files (x86)\Common Files\DocuWare\Imaging\DocuWare.Imaging.Worker.exe.config
    in 7.x Versions: C:\Program Files (x86)\DocuWare\Common\Imaging\DocuWare.Imaging.Worker.exe.config

in section <appSettings> add :

For better quality:
<add key="colorsThresholdPng8" value="5" />
<add key="colorsThresholdPng24" value="512" />
<add key="colorsThresholdJpg" value="8192" />

For best quality
<add key="colorsThresholdPng8" value="0" />
<add key="colorsThresholdPng24" value="256" />
<add key="colorsThresholdJpg" value="100000" />

For best quality of B/W documents only:
<add key="colorsThresholdPng8" value="0" />

The default values are:

<add key="colorsThresholdPng8" value="5" />
<add key="colorsThresholdPng24" value="4096" />
<add key="colorsThresholdJpg" value="4096" />
