Converts this document to any supported format using SVG, OCR, and Raster technologies.
LEADDocument.prototype.convert = function(
jobData
)
convert(
jobData: DocumentConverterJobData
): JQueryPromise<DocumentConvertResult>;
jobData
The job data.
A Promise object that can resolve successfully to an object of type DocumentConvertResult object.
The Convert method allows a document to be converted to any of the supported formats with minimal amount of code.
The output document types can be any type of file format supported by LEADTOOLS, including:
The Convert method will analyze the input and output document types and then automatically use a combination of the LEADTOOLS Raster, SVG, and OCR engines to convert the data using the best possible combination of accuracy and speed. Each conversion operation is called a Document Converter Job in the framework.
This example will show how to load a PDF document and convert it to Microsoft Word DOCX.
