Pre-Conversion Services developer preview

Pre-Conversion Services are included as a "Developer Preview." This feature is in late-stage development and api's marked as such should be used for evaluation purposes only and should not be used in production deployments. Note that these api's may undergo change prior to feature completion. The Pre-Conversion Services will be feature complete in PrizmDoc version 11.1. The Viewing Package Creator API provides a facility to fully convert a document for viewing prior to the creation of a Viewing Session. If a large document is converted for viewing at the time a Viewing Session is created, the user may experience a delay when viewing later pages in the document. By converting a document prior to viewing, the entire document is available for viewing immediately.

Viewing Package Creators

The Viewing Package Creator API provides a facility to fully convert a document for viewing prior to the creation of a Viewing Session. If a large document is converted for viewing at the time a Viewing Session is created, the user may experience a delay when viewing later pages in the document. By converting a document prior to viewing, the entire document is available for viewing immediately.

Note that these routes do not have route keys, as they cannot be re-routed.

POST /v2/viewingPackageCreators

Headers:

Accusoft-Secret: mysecretkey

Body: a JSON object

The table below shows all the properties available for the POST Request:

input.source.fileExtension	{string}	Optional	A file extension that's used if the File Detection Service cannot determine what type of file was uploaded. We will get the extension from "displayName" or "fileName" if this option is not provided.
input.viewingPackageLifetime	{integer}	Optional	Defines the minimum number of integer seconds for the created content to remain available. By default this is 24 hours. If set to 0, content will remain available perpetually.
input.render	{object}	Optional	The object that describes rendering options.
input.render.html5	{object}	Optional	The object that describes rendering options for the HTML5 viewer. A whitelist of the following render properties is used: `alwaysUseRaster`, `rasterResolution`, `svgMaxImageSize` and `vectorTolerance`. They are described in the PrizmDoc Server Viewing Session documentation.
minSecondsAvailable	{integer}	Optional (if a value is not provided, the default value = 3600 seconds will be used)	Defines the minimum number of seconds for the conversion process to remain available to GET status. By default this is 3600 seconds because by default, the Viewing Sessions timeout after 20m.

Create a ViewingPackage with extra options

PrizmDoc Server allows for render options that modify the output of the conversion process. The valid options are documented at the top of this page, but as an example, this is what a request would look like if you only wanted raster content:

Note: When creating a viewing package, watermarks cannot be used and will return an error.

PUT /v2/viewingPackageCreators/{processId}/SourceFile

Headers:

Accusoft-Secret: mysecretkey

Body: a source document of Content-Type application/octet-stream

A request to this URL allows the user to upload a document to an existing viewing package creator which has not yet been provided a source document. When a viewing package creator is configured with input.source.type: 'upload', viewing package creation waits until a PUT request containing the source document is received. After the source document has been successfully uploaded, viewing package creation will resume.

Examples

   PUT http://localhost:3000/v2/viewingPackageCreators/khjyrfKLj2g6gv8fdqg710/SourceFile
   Content-Type: application/octet-stream
   Body: a document

Successful Response:

200 OK

Errored Responses:

When uploading a document for viewing package creation, the following errors may be encountered:

PUT When Not Allowed

If a PUT request is made to upload a file for a viewing package creator which does not have input.source.type: 'upload', then the following error will be returned.

580 NotSupportedForViewingPackageSourceType
Content-Type: application/json
{
    "errorCode": "NotSupportedForViewingPackageSourceType"
}

PUT When File Already Provided

If a PUT request is made to upload a file for a viewing package creator after a file has already been uploaded for that viewing package creator, then the following error will be returned.

580 SourceFileAlreadyProvided
Content-Type: application/json
{
    "errorCode": "SourceFileAlreadyProvided"
}

If a PUT request is made with either a missing or an invalid header Accusoft-Secret, an error similar to the one below will be returned.

403 InvalidSecret
Content-Type: application/json
{
    "errorCode": "InvalidSecret"
}

GET /v2/viewingPackageCreators/{processId}

Headers:

Accusoft-Secret: mysecretkey

Gets the status of an existing viewing package creator.

Requests to this URL can be sent repeatedly while the state="processing". To limit network congestion, an exponential back-off algorithm is recommended. This means that the time interval between each request is increased, which results in a good trade-off between quickly discovering short conversions that have completed and preventing a large number of requests for long conversions.

Upon successful package creation, the response will have the state="complete" with percentComplete=100. The errorCode will be null. Additionally it will include an output property which will contain the created package expiration time. If there is an error during processing, the state="error" with percentComplete=100. The exception to this is, some but not all page failures. In this case the state is set to "complete".

Examples

GET http://localhost:3000/v2/viewingPackageCreators/khjyrfKLj2g6gv8fdqg710

Successful Response:

A response for a package that was successfully generated would look like this:

200 OK
Content-Type: application/json
{
    "input": {
        "source": {
            "type": "document",
            "fileName": "sample.doc",
            "documentId": "unT67Fxekm8lk1p0kPnyg8",

    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "complete",
    "percentComplete": 100
}

The viewing package creation process may encounter three types of errors, which it will report on as follows:

Document Errors

These errors describe the conversion result for a nonexistent, unrecognized, or corrupt document. Note that upon completion in these error cases, the state is set to "error" because no content could be provided for the document. Additionally, an errorCode property will be provided indicating the cause of the error. No output property will be provided when the process completes in an error state.

There can be three possible types of document errors:
- Missing Document: The errorCode will be "DocumentNotFound".
- Unrecognized Document: The errorCode will be "UnrecognizedFileFormat".
- Corrupt Document: The errorCode will be "CorruptDocument".

    "percentComplete": 100,
    "errorCode": "DocumentNotFound | UnrecognizedFileFormat | CorruptDocument"
}

Password Errors

This error describes the conversion result for a password-protected document, which is not supported in this release. A password property may be provided in the request, but it will not be used. Upon completion in this error case, the state is set to "error" because no content could be provided for the document. An errorCode property will be provided indicating an "InternalError". No output property will be provided when the process completes in an error state.

200 OK

Page Failures

These errors will not mark the entire package as errored, but rather report in the output object in a pageFailures array.

200 OK

    "processId": "khjyrfKLj2g6gv8fdqg710",
    "state": "complete",
    "percentComplete": 100
}

Attachment Errors

These errors describe the failure of the conversion to provide an artifact for an attachment in the case where a document supports attachments, such as .EML or .MSG.

If the conversion process finds attachments associated with the document, but the process is unable to provide content for one or more pages, then the state is set to "complete" and an array of pageFailures is returned as a property in the body.

Note: These errors differ from the document page failures by including the addition of an attachment property. This property indicates the name of the attachment (as returned by the PCCIS GET Attachments API). In the eventuality the PPS supports the extraction of nested attachments, the attachments are referenced through an array of paths. Note that the original document is not included in the array of paths. If the original document is "message.eml", with an attachment of "fwd.eml", which has its own attachment of "financial.xls", the array would be ["fwd.eml"] or ["fwd.eml", "financial.xls"].
