Hi Anish,

Thanks for using our products.

As per my understanding, you need to convert individual page of PDF file to separate TIFF image rather than the complete PDF is converted to a multipage TIFF. I have tested the scenario using following code snippet with Aspose.Pdf for .NET 7.7.0 and as per my observations, the blue ink is appearing in resultant images.

C#

//open document
Document pdfDocument = new Document("c:/pdftest/ERIC'S+LTD+PAPER.pdf");

//create Resolution object
Resolution resolution = new Resolution(300);

//create TiffSettings object
TiffSettings tiffSettings = new TiffSettings();
tiffSettings.Compression = CompressionType.None;
tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;
tiffSettings.Shape = ShapeType.Landscape;
tiffSettings.SkipBlankPages = false;

//create TIFF device
TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);

for (int page = 1; page <= pdfDocument.Pages.Count; page++)
{
    //convert a particular page and save the image to file
    tiffDevice.Process(pdfDocument, page, page, "c:/pdftest/ERIC'S+LTD+PAPER_output" + page.ToString() + ".tif");
}

Hi Nayyer Shahbaz

I tried to do the same way which you provided me.
But unfortunately i am not able to get the tiff file.
Please see the below code which i am using.

 Document pdfDocument = new Document(“E:/CO/Input/ERIC’S LTD PAPER.pdf”);

//create Resolution object

Resolution resolution = new Resolution(300);

//create TiffSettings object

TiffSettings tiffSettings = new TiffSettings();

tiffSettings.Compression = CompressionType.None;

tiffSettings.Depth = Aspose.Pdf.Devices.ColorDepth.Default;

tiffSettings.Shape = ShapeType.Landscape;

tiffSettings.SkipBlankPages = false;
            <span style="color:green;">//create TIFF device</span>
            <span style="color:#2b91af;">TiffDevice</span> tiffDevice = <span style="color:blue;">new</span> <span style="color:#2b91af;">TiffDevice</span>(resolution, tiffSettings);
           

            <span style="color:blue;">for</span> (<span style="color:blue;">int</span> page = 1; page <= pdfDocument.Pages.Count; page++)
            {<br>                 tiffDevice.Process(pdfDocument, page, page, <span style="color:#a31515;">"E:/CO/Output"</span> + page.ToString() + <span style="color:#a31515;">".tif"</span>);

            }<br><br>One more thing, Currently i am using Aspose.pdf for .NEt V 7.2.0.0<br>Is this cause any issue<br><br>Regards<br>Anish<br></pre><br>

Hi Anish,

I am pleased to hear that your problem is resolved. Can you please confirm that, by using the latest release version, you managed to get the TIFF images or there have been some other reasons causing a problem during PDF to TIFF conversion. This information will help us in better/further understanding the problem that you have been facing.

Hi Anish,

Thanks for your inquiry. While testing the scenario with Aspose.Pdf for .NET 7.9, I’m afraid I’m unable to reproduce the issue, please find attached image. Please download and try latest Aspose.Pdf for .NET API. Hopefully it will fix the issue. If issue persist then please share your sample code here for further investigation.

Sorry for the inconvenience faced.

Hi Anish,

Thanks for sharing source code. I’ve tested your source code, with slightly change in output file name code, as following. please find enclosed output files. Hopefully it will serve the purpose.

sourceImages[page - 1].Save(Path.Combine(OutputFolder, String.Concat(Path.GetFileNameWithoutExtension(FullInputFileName), page.ToString().PadLeft(3, ‘0’), “.”,“tiff”)));

Please feel free to contact us for any further assistance.
