Hit highlighting does not display desired results after Legal Production

SYMPTOMS

After producing colored TIF files in a Legal Production, hit highlighting is not displaying the level of hit accuracy desired.

CAUSE

The value settings that are applied in the Tiffproducer.dll file are set to the default parameter. Increasing the values of the Tiff producer settings may provide more accuracy with hit highlighting results.

RESOLUTION

• Navigate to the file location: C:\Program Files (x86)\ZyLAB\EDiscovery\Ediscoveryservice\Assemblies\Performers\ZyLAB.EDiscovery.Processors.TiffProducer.dll
• Open the file in a text editing program (ex. notepad).
• Next, modify the Tiff producer settings to reflect a higher quality image.
  • By default, the Tiff production settings are as follows:

<configuration id="Tiff">
<settings>
<setting key="ColorDepth" value="0" />
<setting key="Resolution" value="300" />
<setting key="Compression" value="4" />
<setting key="ImageFormat" value="2" />
<setting key="Multipage" value="true" />
</settings>
</configuration>
<configuration id="ZyXmlTiff">
<settings>
<setting key="ColorDepth" value="0" />
<setting key="Resolution" value="300" />
<setting key="Compression" value="4" />
<setting key="ImageFormat" value="3" />
<setting key="Multipage" value="false" />
</settings>
</configuration>
 

• By modifying the following values of ColorDepth and Compression, it is possible to have a color tiff output that allows for a greater degree of accuracy with hit highlighting.

Possible values for color depth – 0, 24, 32
Possible value for compression – 4, 5

4 is black-white compression scheme that will not work with color images
5 is JPEG-like compression that can be used with 24 and 32 bit images.

<configuration id="Tiff">
<settings>
<setting key="ColorDepth" value="24" />
<setting key="Resolution" value="300" />
<setting key="Compression" value="5" />
<setting key="ImageFormat" value="2" />
<setting key="Multipage" value="true" />
</settings>
</configuration>
<configuration id="ZyXmlTiff">
<settings>
<setting key="ColorDepth" value="24" />
<setting key="Resolution" value="300" />
<setting key="Compression" value="5" />
<setting key="ImageFormat" value="3" />
<setting key="Multipage" value="false" />
</settings>
</configuration>
 

• Note: performing these adjustments may have an impact of production performance.
