The LEADTOOLS CloudServices library provides developers with an easy to use interface to convert files to and from any Raster/Document format that the LEADTOOLS SDK supports. The ConversionEngine class provides two methods to convert files -- ConvertToRaster, and ConvertToDocument. The ConvertToRaster method allows conversion to any file format defined in the RasterImageFormat enum, whereas the ConvertToDocument method allows conversion to any file format defined in the DocumentFormat enum.
Both methods return an IEnumerable stream containing either 1 stream if the output format is multi-page or multiple streams if the input file was multi-page and the output format selected is single-page.
Code:
var inputStream = File.Open(@"leadtools.pdf", FileMode.Open);
LoadDocumentOptions loadOptions = new LoadDocumentOptions()
{
FirstPageNumber = 1,
LastPageNumber = 1
};
ConversionEngine conversionEngine = new ConversionEngine();
var outputStream = conversionEngine.ConvertToRaster(inputStream, loadOptions, RasterImageFormat.TifJpeg411, null); //Returns an enumerable list of streams
foreach(var stream in outputStream)
{
//Process converted stream
}
Code:
var inputStream = File.Open(@"leadtools.pdf", FileMode.Open);
LoadDocumentOptions loadOptions = new LoadDocumentOptions()
{
FirstPageNumber = 1,
LastPageNumber = 1
};
ConversionEngine conversionEngine = new ConversionEngine();
IOcrEngine engine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false);
engine.Startup(null, null, null, @"path/to/OCR Bin Directory");
var outPutStream = conversionEngine.ConvertToDocument(inputStream, loadOptions, DocumentFormat.Doc, engine, null);
foreach (var stream in outputStream)
{
//Process converted stream
}
