RotatePagesOperation

An operation that allows rotation of specific pages in a PDF file.

Sample Usage:


 const credentials = PDFToolsSdk.Credentials.serviceAccountCredentialsBuilder()
           .fromFile("pdftools-api-credentials.json")
           .build(),
       executionContext = PDFToolsSdk.ExecutionContext.create(credentials),
       RotatePages = PDFToolsSdk.RotatePages,
       rotatePagesOperation = RotatePages.Operation.createNew();

 rotatePagesOperation.setInput(PDFToolsSdk.FileRef.createFromLocalFile('~/Documents/rotatePagesOperationInput.pdf',
 	RotatePages.SupportedSourceFormat.pdf));
 rotatePagesOperation.setAngleToRotatePagesBy(PDFToolsSdk.RotatePages.Angle._90);

 rotatePagesOperation.execute(executionContext)
     .then(result => result.saveAsFile('output/rotatePagesOperationOutput.pdf'))
     .catch(err => console.log(err));

Members

(static, constant) SupportedSourceFormat

Properties:

Name	Type	Description
`pdf`	string	Represents "application/pdf" media type

Supported source file formats for RotatePagesOperation.

(static, constant) Angle

Properties:

Name	Type	Description
`_90`	number	Represents 90 degrees clockwise rotation
`_180`	number	Represents 180 degrees clockwise rotation
`_270`	number	Represents 270 degrees clockwise rotation

Supported rotation angle values for RotatePagesOperation.

Methods

(static) createNew() → {RotatePagesOperation}

Constructs a RotatePagesOperation instance.

Returns:

A new RotatePagesOperation instance.

Type: RotatePagesOperation

setInput(sourceFileRefnon-null)

Sets an input file.

Parameters:

Name	Type	Description
`sourceFileRef`	FileRef	An input file.

setAngleToRotatePagesBy(anglenon-null, pageRangesopt)

Sets angle (in clockwise direction) for rotating pages of the input PDF file; can be invoked multiple times to set rotation angle for different set of pages.

Multiple invocation of this method on the same set of pages can result in rotating pages multiple times.

For e.g.:
PageRanges pageRanges = new PDFToolsSdk.PageRanges();
pageRanges.addSinglePage(1);
rotatePagesOperation.setAngleToRotatePagesBy(PDFToolsSdk.RotatePages.Angle._90, pageRanges);
rotatePagesOperation.setAngleToRotatePagesBy(PDFToolsSdk.RotatePages.Angle._180, pageRanges);

Above invocations will effectively rotate pages (as specified by the page ranges) by 270 degrees.

If pageRanges is not provided, all pages of the input PDF are rotated by the specified angle.

Parameters:

Name	Type	Attributes	Description
`angle`	RotatePagesOperation.Angle		Angle for rotation; see RotatePagesOperation.Angle for valid angle values.
`pageRanges`	PageRanges	<optional>	Page ranges of the PDF file for rotation.

execute(contextnon-null) → {Promise.<FileRef>}

Executes this operation using the supplied context and returns a Promise which resolves to the operation result.

The resulting file may be stored in the system temporary directory (per the os.tempdir(), symlinks are resolved to the actual path). See FileRef for how temporary resources are cleaned up.

Parameters:

Name	Type	Description
`context`	ExecutionContext	The context in which the operation will be executed.

Throws:

if an API call results in an error response.

Type

ServiceApiError
if service usage limits have been reached or credentials quota has been exhausted.

Type

ServiceUsageError

Returns:

A promise which resolves to the operation result.

Type: Promise.<FileRef>
