Introduction

Configure PrizmDoc Server using the services Central Configuration file. The configuration file will perform environment variable expansion in path values. The environment variable must be contained within a quoted string and enclosed with the % character.

For example, "%ALLUSERSPROFILE%" or "%my_path%/subpath" are both valid paths containing environment variables which will be expanded at runtime.

NOTE: PrizmDoc Cloud uses specific default values that differ from the self-hosted default values as noted in the PrizmDoc Cloud Default Values section below.

Working with the Central Configuration File

The locations for the Central Configuration file are:
- Windows: C:\Prizm\prizm-services-config.yml (given the default installation directory)
- Linux: /usr/share/prizm/prizm-services-config.yml (given the default installation directory)
- Docker: the folder that you mapped as /config when creating the container. See Installing / Using Docker for more details.
- Kubernetes: configuration parameters are provided via a ConfigMap resource. See Deployment to Kubernetes Guidance for more details.
After making any changes to the configuration files, you need to restart the PrizmDoc Server.

IMPORTANT: Any time you make a change to the configuration files that affects document output, you must clear your cache.

Cache

`cache.directory`

Directory where cache data is stored.

Supported Values: Any valid path to a directory with read and write permissions.

Default Value: Traditional Linux Install Packages and Windows: <install_dir>/cache

For example:

/usr/share/prizm/cache
C:\Prizm\cache
Docker: /data/cache

NOTE: When using PrizmDoc Docker containers, we recommend that you keep this property unchanged.

Central Database

The use of a Central Database is required in the following cases:

When using an Offline Metered License.
When the "v3" Viewing Packages API is turned on.

This feature is disabled by default. When the features listed above are not used, PrizmDoc Server will not use a database, or even check for its existence in the configuration.

`database.connectionString`

Connection string to the central database. MySQL is the only database currently supported. A MySQL example:

"mysql://prizm-user:password@prizm-server.database.host:3306/prizmdoc_server_db"

Supported Values: N/A

Default Value: ""

Environment Options

`eps.env`

One or more additional environment settings for the Email Processing Service, in the following form: eps.env.var_name: "var_value" Wherevar_name can be any valid name for the environment variable and var_value is a text value for the environment variable.

Examples:

eps.env.VAR1: "Value1"
eps.env.VAR2: "Value2"

Supported Values: Any string value

Default Value: ""

`pdfps.env`

One or more additional environment settings for the PDF Processing Service, in the following form: pdfps.env.var_name: "var_value" Wherevar_name can be any valid name for the environment variable and var_value is a text value for the environment variable.

Examples:

pdfps.env.VAR1: "Value1"
pdfps.env.VAR2: "Value2"

Supported Values: Any string value

Default Value: ""

Fidelity

`fidelity.msOfficeCluster.host`

This value is used to enable Microsoft Office Conversion connectivity for PrizmDoc servers running on Linux. Set this value on a PrizmDoc server running on Linux to the hostname (or the IP of a single PrizmDoc server, or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc.

Supported Values: A valid IP address or hostname

Default Value: ""

`fidelity.msOfficeCluster.port`

This value is used to enable Microsoft Office Conversion connectivity for PrizmDoc servers running on Linux. Set this value on a PrizmDoc server running on Linux to the public port of a single PrizmDoc server (or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc. To connect to a single server or load balancer specify network.publicPort parameter of the remote server.

Supported Values: Any open HTTP port on the server

Default Value: 0

`fidelity.msOfficeCluster.scheme`

This value is used to enable encrypted communication between PrizmDoc servers running on Linux and PrizmDoc servers providing the native rendering of Microsoft documents.

When set to http, PrizmDoc uses the HTTP scheme for connecting to the PrizmDoc MSO server or cluster.

When set to https, PrizmDoc uses the HTTPS scheme for connecting to the PrizmDoc MSO server or cluster.

NOTE: This parameter only affects the way that the server running on Linux routes requests to the MSO server or cluster, but does not make the MSO server or cluster support HTTPS protocol for incoming requests. You will need to set up a reverse proxy on your PrizmDoc MSO instance or cluster, and use it as an HTTPS terminator for that instance (cluster).

Supported Values: One of the following strings: http, https

Default Value: http

`fidelity.msOfficeDocumentsRenderer`

Specifies the renderer to use with Microsoft Office documents.

When set to auto, PrizmDoc decides which renderer to use based on the MSO feature license state. If the MSO feature is present, then the Microsoft Office renderer will be used. Otherwise, LibreOffice will be used.

When set to libreoffice, PrizmDoc will use the LibreOffice renderer. If you are intending to use the LibreOffice renderer permanently, contact info@accusoft.com to obtain a metered license or a license with the MSO feature disabled.

When set to msoffice, PrizmDoc will use the Microsoft Office renderer if the MSO feature is enabled in the license key, otherwise a licensing error will be reported.

The parameter affects only Microsoft Office documents, RTF, and CSV files. Other documents will continue to be rendered with LibreOffice. For a complete list of supported file types see Supported File Formats.

NOTE: For PrizmDoc Cloud, the default value for fidelity.msOfficeDocumentsRenderer is msoffice.

Supported Values: One of the following strings: auto, libreoffice, or msoffice

Default Value: auto

`fidelity.svgMaxImageSize`

For source documents which contain images, ensures that the images in the SVG delivered to the browser do not exceed a particular pixel width and/or height. For example, a value of 8000 would ensure that any images in a PDF whose width or height were greater than 8000 pixels would be down-sampled before the image was added to the final SVG. A typical value is 8000. The default value for this property is configurable. The out-of-box configuration uses a default value of 8000. Use 0 to disable the optimization.

Supported Values: Any integer greater than 0

Default Value: 8000

`fidelity.vectorBackgroundColor.view.default`

Defines the background color for viewing CAD documents if the background is not specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG, and TIFF. DGN documents define their own background color, so this property does not affect them. Use fidelity.vectorBackgroundColor.view.override to define the background color (and ignore the background color specified in the document).

Supported Values: CSS color name, e.g., gray, or a hex RGB value, e.g., #FFFFFF

Default Value: white (#FFFFFF)

`fidelity.vectorBackgroundColor.view.override`

Defines the background color for viewing CAD documents, ignoring the background specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG and TIFF, ignoring the background specified in the document. Overrides fidelity.vectorBackgroundColor.view.default.

Supported Values: CSS color name, e.g., gray, or a hex RGB value, e.g., #FFFFFF, or none

Default Value: none

`fidelity.vectorTolerance`

For CAD documents, controls how much path simplification is allowed. The path simplification algorithm will merge points which are "close together" to create an optimized SVG. You can think of this value as defining what "close together" means. A typical value is 0.3. Higher values introduce more simplification, but also more distortion. The value cannot be greater than 10.0. The default value for this property is configurable. The out-of-box configuration uses a default value of 0.3. Use 0 to disable the optimization.

Supported Values: A positive floating point value with a minimum value of 0.0 and a maximum value of 10.0

Default Value: 0.3

If you change this value to decrease the cache lifetime, make sure that you also adjust the viewing.sessionConstraints.minSecondsAvailable.max value to represent the same or shorter amount of time.

NOTE: For PrizmDoc Cloud, the default value for viewing.cacheLifetime is 43h.

Default Value: 1d

`viewing.contentEncryption.enabled`

Controls whether or not content is encrypted by the back end before being transmitted to a Viewer. The Viewer will decrypt the content in the browser. This is useful for DRM (Digital Rights Management), making it more difficult to copy protected content that has been delivered to the browser.

Supported Values: true, false

Default Value: false

`viewing.sessionConstraints.countOfInitialPages.max`

Maximum allowed value for the countOfInitialPages JSON property when creating a new viewing session. Together with viewing.sessionConstraints.countOfInitialPages.min creates a range filter that will be applied to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

This property is one of several that can be used to limit unwanted values from being used within the JSON properties of the initial POST request to create a viewing session. These filter values are useful for preventing mistaken or malicious values from being sent that could affect server behavior.

Supported Values: Any natural number not less than viewing.sessionConstraints.countOfInitialPages.min

Default Value: 10

`viewing.sessionConstraints.countOfInitialPages.min`

Minimum allowed value for the countOfInitialPages JSON property when creating a new viewing session.

Supported Values: Any natural number

Default Value: 0

`viewing.sessionConstraints.documentExtension.regex`

Creates a regex filter that will be applied to the documentExtension JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Supported Values: Valid regular expression using the .NET Regular Expression Language

Default Value: .*

`viewing.sessionConstraints.documentSource.allowedValues`

Creates a value filter that will be applied to the documentSource JSON property when creating a new viewing session to ensure appropriate values are being set. If the actual property value fails to match the filter, an error will be returned and the viewing session will not be created.

Allowing a combination of document sources here enables you to create viewing sessions with different sources on the fly without needing to modify this config file. This property is one of several that can be used to limit unwanted values from being used within the JSON properties of the initial POST request to create a viewing session. These filter values are useful for preventing mistaken or malicious values from being sent that could affect server behavior.

NOTE: For PrizmDoc Cloud, the default value for viewing.sessionConstraints.documentSource.allowedValues is api.
