Convert Tif to PDF using c# .net core 2.1 with Aspose.PDF - Parameter is invalid

Aspose.PDF Product Family

Hi Team,

I am using licence version product of Aspose.

we are using .net core-2.1 c# and windows 10.

if we are using memory stream and bit map then some files only are converted (tif to pdf) successfully details as given below:
Aspose.Pdf.Document doc = new Aspose.Pdf.Document();
// Add a page to pages collection of document
Aspose.Pdf.Page page = doc.Pages.Add();
// Load the source image file to Stream object
FileStream fs = new FileStream(jpgImagePath, FileMode.Open, FileAccess.Read);
byte[] tmpBytes = new byte[fs.Length];
fs.Read(tmpBytes, 0, int.Parse(fs.Length.ToString()));

            MemoryStream mystream = new MemoryStream(tmpBytes);
            // Instantiate BitMap object with loaded image stream
            System.Drawing.Bitmap b = new System.Drawing.Bitmap(mystream)

But if we are using TiffImage class of Aspose then unable to load image details as given below:

//using (TiffImage image = (TiffImage)Image.Load(jpgImagePath))

Kindly suggest to me for best way to convert tiff(multiple pages also.) to pdf.

Please try using following code snippet which can also convert a multipage TIFF image to PDF:

Document pdf1 = new Document();

MemoryStream ms = new MemoryStream();
new FileStream(dataDir + "test.tiff", FileMode.Open).CopyTo(ms);
Bitmap myimage = new Bitmap(ms);

FrameDimension dimension = new FrameDimension(myimage.FrameDimensionsList[0]);
int frameCount = myimage.GetFrameCount(dimension);

for (int frameIdx = 0; frameIdx <= frameCount - 1; frameIdx++)
{
 Page sec = pdf1.Pages.Add();
 myimage.SelectActiveFrame(dimension, frameIdx);
 MemoryStream currentImage = new MemoryStream();
 myimage.Save(currentImage, ImageFormat.Tiff);
 if (myimage.Width > myimage.Height)
 {
  sec.PageInfo.IsLandscape = true;
 }
 else
 {
  sec.PageInfo.IsLandscape = false;
 }
 sec.PageInfo.Margin = new MarginInfo(0, 0, 0, 0);
 sec.PageInfo.Height = myimage.Height;
 sec.PageInfo.Width = myimage.Width;
 Aspose.Pdf.Image imageht = new Aspose.Pdf.Image();
 imageht.ImageStream = currentImage;
 sec.Paragraphs.Add(imageht);
}
pdf1.Save(dataDir + "TifftoPDF.pdf");

Hi @asad.ali,

Thanks for your update.

There are some question as given below:

1-Kindly share list of files here covering all the file, file extension and its limitations for pdf conversion.

2-About what files are and are not permitted? I don’t expect every file to be converted in every case, but if we know the basic requirements then we can tell users to format files correctly.

Because i am facing same issue with multiple extensions of file like( TIFF,BMP, PNG …etc).
I am using license version everything’s.

In any one contact directly like(meeting, call mail etc)that is more better for us.

Regards
Indresh
