The method starts the processing task with the specified parameters.
This method allows you to process several images using the same settings and obtain recognition result as a multi-page document. You can upload several images to one task using submitImage method.
It is also possible to specify up to three file formats for the result, in which case the server response for the completed task will contain several result URLs.
For details on task cost please see billing terms.

Specifies the source of the image. It can be either a scanned image, or a photograph created with a digital camera.

If either of XML export formats is selected, barcodes are recognized on the image and saved to output XML no matter which profile is used for recognition.
Please note that setting multiple export formats does not affect the cost of task processing.
|xml:writeFormatting||No||"false"||Specifies whether the paragraph and character styles should be written to an output file in XML format. This parameter can be used only if the exportFormat parameter contains xml or xmlForCorrectedImagevalue. The parameter can have one of the following values:
|xml:writeRecognitionVariants||No||"false"||Specifies whether the variants of characters recognition should be written to an output file in XML format. This parameter can be used only if the exportFormat parameter contains xmlvalue. The parameter can have one of the following values:
Specifies whether the result must be written as tagged PDF. This parameter can be used only if the exportFormat parameter contains one of the values for export to PDF. It can have one of the following values:
