JPG to PDF Convertor in C#

Question

I would like to convert from an image (like jpg or png) to PDF.

I\'ve checked out ImageMagickNET, but it is far too complex for my needs.

What other .NET so

Answer 1

Another working code, try it

public void ImagesToPdf(string[] imagepaths, string pdfpath)
{
        iTextSharp.text.Rectangle pageSize = null;

        using (var srcImage = new Bitmap(imagepaths[0].ToString()))
        {
            pageSize = new iTextSharp.text.Rectangle(0, 0, srcImage.Width, srcImage.Height);
        }

        using (var ms = new MemoryStream())
        {
            var document = new iTextSharp.text.Document(pageSize, 0, 0, 0, 0);
            iTextSharp.text.pdf.PdfWriter.GetInstance(document, ms).SetFullCompression();
            document.Open();
            var image = iTextSharp.text.Image.GetInstance(imagepaths[0].ToString());
            document.Add(image);
            document.Close();

            File.WriteAllBytes(pdfpath+"cheque.pdf", ms.ToArray());
        }
}

You need Acrobat to be installed. Tested on Acrobat DC. This is a VB.net code. Due to that these objects are COM objects, you shall do a 'release object', not just a '=Nothing". You can convert this code here: https://converter.telerik.com/

Private Function ImageToPDF(ByVal FilePath As String, ByVal DestinationFolder As String) As String
    Const PDSaveCollectGarbage  As Integer = 32
    Const PDSaveLinearized      As Integer = 4
    Const PDSaveFull            As Integer = 1
    Dim PDFAVDoc                As Object = Nothing
    Dim PDFDoc                  As Object = Nothing

    Try
        'Check destination requirements
        If Not DestinationFolder.EndsWith("\") Then DestinationFolder += "\"
        If Not System.IO.Directory.Exists(DestinationFolder) Then Throw New Exception("Destination directory does not exist: " & DestinationFolder)
        Dim CreatedFile As String = DestinationFolder & System.IO.Path.GetFileNameWithoutExtension(FilePath) & ".pdf"
        'Avoid conflicts, therefore previous file there will be deleted
        If File.Exists(CreatedFile) Then File.Delete(CreatedFile)

        'Get PDF document
        PDFAVDoc = GetPDFAVDoc(FilePath)
        PDFDoc = PDFAVDoc.GetPDDoc

        If Not PDFDoc.Save(PDSaveCollectGarbage Or PDSaveLinearized Or PDSaveFull, CreatedFile) Then Throw New Exception("PDF file cannot be saved: " & PDFDoc.GetFileName())
        If Not PDFDoc.Close() Then Throw New Exception("PDF file could not be closed: " & PDFDoc.GetFileName())
        PDFAVDoc.Close(1)
        Return CreatedFile
    Catch Ex As Exception
        Throw Ex
    Finally
        System.Runtime.InteropServices.Marshal.ReleaseComObject(PDFDoc)
        System.Runtime.InteropServices.Marshal.FinalReleaseComObject(PDFDoc)
        PDFDoc = Nothing
        System.Runtime.InteropServices.Marshal.ReleaseComObject(PDFAVDoc)
        System.Runtime.InteropServices.Marshal.FinalReleaseComObject(PDFAVDoc)
        PDFAVDoc = Nothing
        GC.Collect()
        GC.WaitForPendingFinalizers()
        GC.Collect()
    End Try
End Function
