    Markup Burners
    In This Topic

    Introduction

    The markup burners REST API allows your application to “burn” markup into a document, producing a new PDF with annotations applied.

    For application development in.NET, we recommend using the PrizmDoc Server .NET SDK instead of the REST API. See the .NET SDK How to Guides for examples of how to perform markup burning and redaction with the.NET SDK.

    Available URLs

    URL Description
    POST /PCCIS/V1/MarkupBurner Creates and starts a new MarkupBurner.
    GET /PCCIS/V1/MarkupBurner/{processId} Gets the status and result of an existing MarkupBurner.
    POST /PCCIS/V1/ViewingSession/u{viewingSessionId}/MarkupBurner Starts a new MarkupBurner using the source document of a viewing session and provided markup data as input.
    GET /PCCIS/V1/ViewingSession/u{viewingSessionId}/MarkupBurner/{processId} Gets the status of a MarkupBurner for a viewing session.
    GET /PCCIS/V1/ViewingSession/u{viewingSessionId}/MarkupBurner/{processId}/Document Gets the output result of a MarkupBurner process for a viewing session.

    POST /PCCIS/V1/MarkupBurner

    Creates and starts a new MarkupBurner.

    NOTE: CAD files are not supported.

    NOTE: When applying redactions, PDF annotations are never removed.

    NOTE: There are limitations on what content is removed under the rectangle redaction box on vector content in PDF files when the markup burner burns the redactions.

    • When redacting a vector line, a small portion of the lines under the redaction box may still exist under the redaction.
    • When redacting a vector graphic with color filling, such as a colored in half circle, the color will still remain under the redaction rectangle.
    • When redacting a vector graphic rectangle, they are fully removed only if the PDF graphic rectangle is fully overlapped by the redaction rectangle. If they are partially overlapped then the part not overlapped remains unredacted.

    A MarkupBurner represents a process that runs on the server to "burn" markup into a document. The "burning" process makes the markup definitions a permanent part of a document. The server process is started by this request then a response is sent. Use the [GET /PCCIS/V1/MarkupBurner/{processId}] URL below to get the status and results of an in-progress or completed MarkupBurner process.

    The input required to create a MarkupBurner is two WorkFile objects; one representing the JSON or XML which defines the markup to burn, the other representing the source document on which to burn the markup. Refer to the work file API topic for more information.

    A new document is created that contains the burned-in markup. The source document will not be modified. The new document will be made available by a new WorkFile ID.

    By default, MarkupBurner objects will be automatically deleted 20 minutes after they are created.

    Request

    Request Headers

    Name Description
    Content-Type Must be application/json
    Accusoft-Affinity-Token The affinityToken of the work files specified by input.documentFileId and input.markupFileId. Required when server clustering is enabled.

    Request Body

    In the request body, provide JSON containing the following properties:

    • input (Object) Input to create the MarkupBurner.

      • documentFileId (String) Required. The ID of the WorkFile that represents the document to burn in the markup. This document will not be modified.

        • redactionOptions (Object) Redaction options. May contain:

          • mode (String) How redactions should be applied. May be one of the following:

            • "normal" - Actually redact the document, removing document content covered by redactions, drawing opaque redaction rectangles, and drawing any associated redaction reason text in the center of the rectangles.
            • "draft" - Do NOT actually redact the document. Instead, indicate which parts of the document would be redacted by drawing partially transparent redaction rectangles over the parts of the document that would be redacted. In order to avoid interfering with the original document content, redaction reason text will not be drawn in the center of the transparent redaction rectangles.

            Default is "normal".

          • draftOptions (Object) Options to apply when mode is set to "draft" (ignored otherwise). May contain:
            • opacity (number) Controls the opacity of redactions when input.redactionOptions.mode is set to "draft". Must be a value between 0 and 1 where 0 is fully transparent and 1 is fully opaque. Default is 0.2.
          • includeCategories (Array of String) When present, limits the burning to only include the specified categories of mark types. The following categories are available:

            • "annotations"
            • "redactions"
            • "signatures"

            For example, if you only want to apply redactions you could specify:

            "includeCategories": ["redactions"]

            Or, if you only wanted to apply annotations and signatures you could specify:

            "includeCategories": ["annotations", "signatures"]

      • markupFileId (String) Required. The ID of the WorkFile that represents the JSON or XML document which contains the markup definition.
      • minSecondsAvailable (Integer) The minimum number of seconds which this MarkupBurner must remain available. The default lifetime is defined by the processIds.lifetime central configuration parameter. This value is ignored if it is shorter than the default value.

    Successful Response

    Response Body

    If successful, this method returns JSON containing the following properties:

    • input (Object) Input we accepted to create the MarkupBurner.
      • documentFileId (String) The ID of the WorkFile that represents the document to burn in the markup. This document will not be modified. This is an echo of what was passed in by the request.
      • markupFileId (String) The ID of the WorkFile that represents the JSON or XML document which contains the markup definition. This is an echo of what was passed in by the request.
    • expirationDateTime (String) The date and time (in ISO 8601 Extended Format) when the MarkupBurner will be deleted.
    • processId (String) The ID of the MarkupBurner.
    • state (String) The current state of the markup burning process running on the server. This will always be "processing" in this response.
    • percentComplete (Integer) The percentage (0 – 100) complete of the markup burning process. This will always be 0 in this response.

    • output (Object)
      • documentFileId (String) The ID of the new WorkFile that represents a new document with markup burned into it. This will always be null in this response.
    • affinityToken (String) Affinity token for this search context. Present when clustering is enabled.

    Error Responses

    Status Code Description
    400 Bad Request, if input.documentFileId, input.markupFileId is missing or invalid format, or if minSecondsAvailable is not a number.
    405 Method Not Allowed, if POST HTTP method is not used.
    480 with JSON errorCode "LicenseCouldNotBeVerified". The server's license could not be verified. If you are evaluating the product without a license, the product is running in evaluation mode and this particular part of the product is unavailable without a license. If you have a license, make sure you configured your license correctly, that your license has not expired, and that you have not exceeded any license limits (such as, for a Cloud License, the total number of logical CPU cores in use).

    POST /PCCIS/V1/ViewingSession/u{viewingSessionId}/MarkupBurner

    Starts a new MarkupBurner using the source document of a viewing session and a provided markup data as input. When the asynchronous process is ultimately finished, the output will be a new document which includes the provided markup as part of the document itself (the original source document of the viewing session is left unaltered).

    This is a specialized URL which allows you to do markup burning against the source file of an existing viewing session without needing to use the work file API.

    This request merely begins the markup burning process. Once started, you poll the status of the process using the [GET /PCCIS/V1/ViewingSession/u{viewingSessionId}/MarkupBurner/{processId}] URL below to know when the process has completed.

    Request

    Request Headers

    Name Description
    Content-Type Specifies the type of content being provided to the markup burner process. It must be application/xml or application/json depending on the markup format used in the request body.

    URL Parameters

    Parameter Description
    {viewingSessionId} The id provided in the response from POST /PCCIS/V1/ViewingSession.

    Query String Parameters

    Parameter Description
    {redactionMode} How redactions should be applied. May be one of the following:
    • "normal" - Actually redact the document, removing document content covered by redactions, drawing opaque redaction rectangles, and drawing any associated redaction reason text in the center of the rectangles.
    • "draft" - Do NOT actually redact the document. Instead, indicate which parts of the document would be redacted by drawing partially transparent redaction rectangles over the parts of the document that would be redacted. In order to avoid interfering with the original document content, redaction reason text will not be drawn in the center of the transparent redaction rectangles.
    Default is "normal".
    {redactionDraftOpacity} Controls the opacity of redactions when redactionMode is set to "draft". Must be a value within 0 and 1 where 0 is fully transparent and 1 is fully opaque. Default is 0.2.
    {RemoveFormFields} Optional parameter indicating which interactive form fields to remove from the source document upon markup burner process. Currently only "acroform" value is supported. Please see example below.

    Request Body

    The JSON or XML markup to burn into the source document.

    Response Body

    If successful, a JSON object which may contain:

    • processId (String) The id of the process.
    • state (String) The current state of the markup burning process running on the server. This will always be "processing" in the initial POST response.
    • percentComplete (Integer) The percentage (0 – 100) complete of the process. This will always be 0 in the initial POST response.
    • input (null) Legacy property which exists only for backwards compatibility. Value will always be null.
    • output (null) Legacy property which exists only for backwards compatibility. Value will always be null.

    Error Responses

    Status Code Description
    404 Not Found, if {viewingSessionId} does not exist.
    405 Method Not Allowed, if POST HTTP method is not used.
    480 An invalid input value was used. See errorDetails in the response body.
