convert image to pdf?

You can use LEADTOOLS Document SDK technology in your application.

https://www.leadtools.com/help/sdk/v21/dh/doxc/introduction.html

You can leverage the DocumentConverter class to convert images and documents using the best combination of accuracy and speed.

Here is some sample code:

using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
{
ocrEngine.Startup(null, null, null, null);
using (DocumentConverter _converter = new DocumentConverter())
{
string inputImage = @"FILE PATH TO INPUT IMAGE";
string outputPDF = @"FILE PATH TO OUTPUT IMAGE";
DocumentFormat format = DocumentFormat.Pdf;
DocumentWriter documentWriter = new DocumentWriter();
// Get the current PDF options
PdfDocumentOptions pdfOptions = documentWriter.GetOptions(DocumentFormat.Pdf) as PdfDocumentOptions;
pdfOptions.ImageOverText = true;
documentWriter.SetOptions(DocumentFormat.Pdf, pdfOptions);
_converter.SetDocumentWriterInstance(documentWriter);
_converter.SetOcrEngineInstance(ocrEngine, false);
var jobData = DocumentConverterJobs.CreateJobData(inputImage, outputPDF, format);
var job = _converter.Jobs.CreateJob(jobData);
_converter.Jobs.RunJob(job);
if (job.Status == DocumentConverterJobStatus.Success)
{
Console.WriteLine("Success");
}
else
{
Console.WriteLine("{0} Errors", job.Status);
foreach (var error in job.Errors)
{
Console.WriteLine(" {0} at {1}: {2}", error.Operation, error.InputDocumentPageNumber, error.Error.Message);
}
}
}
}
