Convert Image to PDF on Server/Desktop

Many image types can be converted to PDF Documents using PDF.Convert.ToPDF method. For a complete list of formats supported, please refer to Desktop/Server image formats or Web image formats. Some of the formats such as HEIC and PSD formats require an additional plugin called the Advanced Imaging Module. More information about the module and download links can be found in the advanced imaging module guide.

1// Start with a PDFDoc (the conversion destination)
2PDFDoc doc = new PDFDoc();
3
4// perform the conversion with no optional parameters
5Convert.ToPdf(doc, filename);

1// Start with a PDFDoc (the conversion destination)
2PDFDoc doc;
3
4// perform the conversion with no optional parameters
5Convert::ToPdf(doc, filename);

1// Start with a PDFDoc (the conversion destination)
2PDFDoc doc = new PDFDoc();
3
4// perform the conversion with no optional parameters
5Convert.toPdf(doc, filename);

1const doc = await PDFNet.PDFDoc.create();
2
3// perform the conversion with no optional parameters
4await PDFNet.Convert.toPdf(doc, filename);

1# Start with a PDFDoc (the conversion destination)
2doc = PDFDoc()
3
4# perform the conversion with no optional parameters
5Convert.ToPdf(doc, filename)

1' Start with a PDFDoc (the conversion destination)
2Dim doc As PDFDoc = New PDFDoc
3
4' perform the conversion with no optional parameters
5Convert.ToPdf(doc, filename)

For the image formats that are exclusively supported by Advanced Imaging module, the path containing the module should be added using PDFNet.AddResourceSearchPath prior to invoking the PDF.Convert.ToPDF method. The following snippets demonstrate how this can be done.

1// Use a try-catch block here to catch PDFNetException
2PDFNet.AddResourceSearchPath('relative/path/to/Lib/');
3using (PDFDoc pdfdoc = new PDFDoc())
4{
5    pdftron.PDF.Convert.ToPdf(pdfdoc, input_path + input_file);
6	pdfdoc.Save(output_path + output_file_name, SDFDoc.SaveOptions.e_remove_unused);
7}

1// Use a try-catch block here to catch PDFNetException
2PDFNet::AddResourceSearchPath('relative/path/to/Lib/');
3PDFDoc pdfdoc;
4Convert::ToPdf(pdfdoc, input_path + input_file);
5pdfdoc.Save(outputPath + outputFile, SDF::SDFDoc::e_linearized, NULL);

1// Use a try-catch block here to catch PDFNetException
2PDFNet.addResourceSearchPath('relative/path/to/Lib/');
3PDFDoc doc = new PDFDoc();
4Convert.toPdf(doc, input_path + input_file);
5doc.save(outputFile, SDFDoc.SaveMode.LINEARIZED, null);

1const main = async () => {
2	// Use a try-catch block here to catch PDFNetException
3	await PDFNet.addResourceSearchPath('relative/path/to/Lib/');
4	const doc = await PDFNet.PDFDoc.create();
5    await PDFNet.Convert.toPdf(doc, inputPath + input_file);
6	await doc.save(outputPath + output_file_name, PDFNet.SDFDoc.SaveOptions.e_linearized);
7};
8PDFNet.runWithCleanup(main).then(function(){ PDFNet.shutdown(); });

1PDFNet.AddResourceSearchPath('relative/path/to/Lib/')

3# Start with a PDFDoc (the conversion destination)
4doc = PDFDoc()
5
6# perform the conversion with no optional parameters
7Convert.ToPdf(doc, inputFileName)
8doc.Save(ouputPath + outputFileName, 0)

1// Use a try-catch block here to catch PDFNetException
2PDFNet.AddResourceSearchPath('relative/path/to/Lib/')

4Using pdfdoc As PDFDoc = New PDFDoc()
5    pdftron.PDF.Convert.ToPdf(pdfdoc, input_path & input_file)
6	pdfdoc.Save(output_path & output_file_name, SDFDoc.SaveOptions.e_remove_unused)
7End Using

Sample

For a complete working sample that uses the Advanced Imaging Module and pdftron.PDF.Convert.ToPdf to convert formats such as HEIC and PSD to PDF, see the AdvancedImagingTest sample . This same code can be used to integrate the module into your application or project.
