I am trying to convert a pdf file existing on server into tiff image(As my PDF may have more than 1 frame). I tried multiple links and found spire.pdf
I am following a tutorial
https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Conversion/Save-PDF-Document-as-tiff-image.html
public ActionResult OpenFilee(string fileID)
{
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(Path.Combine(Server.MapPath("~/SafetyUploadedFiles/") +
fileID));
JoinTiffImages(SaveAsImage(doc), "res.tiff", EncoderValue.CompressionLZW);
System.Diagnostics.Process.Start("res.tiff");
return View();
}
private static Image[] SaveAsImage(PdfDocument document)
{
Image[] images = new Image[document.Pages.Count];
for (int i = 0; i < document.Pages.Count; i++)
{
images[i] = document.SaveAsImage(i);
}
return images;
}
private static ImageCodecInfo GetEncoderInfo(string mimeType)
{
ImageCodecInfo[] encoders = ImageCodecInfo.GetImageEncoders();
for (int j = 0; j < encoders.Length; j++)
{
if (encoders[j].MimeType == mimeType)
return encoders[j];
}
throw new Exception(mimeType + " mime type not found in ImageCodecInfo");
}
public static void JoinTiffImages(Image[] images, string outFile, EncoderValue compressEncoder)
{
//use the save encoder
Encoder enc = Encoder.SaveFlag;
EncoderParameters ep = new EncoderParameters(2);
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
ep.Param[1] = new EncoderParameter(Encoder.Compression, (long)compressEncoder);
Image pages = images[0];
int frame = 0;
ImageCodecInfo info = GetEncoderInfo("image/tiff");
foreach (Image img in images)
{
if (frame == 0)
{
pages = img;
//save the first frame
pages.Save(outFile, info, ep);
}
else
{
//save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
pages.SaveAdd(img, ep);
}
if (frame == images.Length - 1)
{
//flush and close.
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
pages.SaveAdd(ep);
}
frame++;
}
}
Getting this error
A generic error occurred in GDI+.
on the following line:
pages.Save(outFile, info, ep);

I am stuck. Currently I am trying to simulate pulling a binary blob from a database that is supposed to be a TIFF image. I use this gist image.tif in the image variable to do so. I am pretty sure I am close to making this happen. It's that the issue probably has to do with how I am converting the string to byte array or something. Basically this application throws an exception stating that it can't create a PDF with 0 frames. At this point I must admit that I may be in over my head on this one. Could someone be so kind and help me the rest of the way with this one?
The code is included below:
using System;
using System.Drawing;
using PdfSharp.Pdf;
using PdfSharp.Drawing;
using System.IO;
using System.Drawing.Imaging;
using System.Text;
namespace ConvertTifToPDFFile
{
class Program
{
static void Main(string[] args)
{
string image = "";
byte[] imageAsByteStream = Encoding.ASCII.GetBytes(image);
int imageByteStreamLength = imageAsByteStream.Length;
string base64EncodedImage = Convert.ToBase64String(imageAsByteStream);
imageAsByteStream = Encoding.ASCII.GetBytes(base64EncodedImage);
Stream imageStream = TiffImageSplitter.ByteArrayToMemoryStream(imageAsByteStream);
// Image splitImage = TiffImageSplitter.getTiffImage(imageStream, 1);
TiffImageSplitter.tiff2PDF(imageStream);
}
}
public class TiffImageSplitter
{
private static TiffImageSplitter tiff = new TiffImageSplitter();
public static void tiff2PDF(Stream imageByteStream)
{
PdfDocument doc = new PdfDocument();
int pageCount = getPageCount(imageByteStream);
for (int i = 0; i < pageCount; i++)
{
PdfPage page = new PdfPage();
Image img = getTiffImage(imageByteStream, 1);
XImage imgFrame = XImage.FromGdiPlusImage(img);
page.Width = imgFrame.PointWidth;
page.Height = imgFrame.PointHeight;
doc.Pages.Add(page);
XGraphics xgr = XGraphics.FromPdfPage(doc.Pages[i]);
xgr.DrawImage(img, 0, 0);
}
doc.Save("C:/temp/test.pdf");
doc.Close();
}
public static Image getTiffImage(Stream imageStream, int pageNumber)
{
MemoryStream ms = null;
Image returnImage = null;
try
{
ms = new MemoryStream();
Image sourceImage = Image.FromStream(imageStream, true, true);
Guid objGuid = sourceImage.FrameDimensionsList[0];
FrameDimension objDimension = new FrameDimension(objGuid);
sourceImage.SelectActiveFrame(objDimension, pageNumber);
sourceImage.Save(ms, ImageFormat.Tiff);
returnImage = Image.FromStream(ms);
}
catch (Exception ex)
{
Console.WriteLine("{0} Exception caught.", ex);

}
return returnImage;
}
public static MemoryStream ByteArrayToMemoryStream(byte[] bytestream)

IMPORTANT!!!! First of all, your example tiff isn't valid at all. It can't be read by any file editor. I have had to take these ones for testing.
Then, the code has couple errors:
1) I don't understand what've done with strings but reading files and BLOBs are same:
static void Main(string[] args)
{
//string image = "";
//byte[] imageAsByteStream = Encoding.ASCII.GetBytes(image);
byte[] imageAsByteStream = File.ReadAllBytes("../../../MARBIBM.TIF");
//int imageByteStreamLength = imageAsByteStream.Length;
//string base64EncodedImage = Convert.ToBase64String(imageAsByteStream);
//imageAsByteStream = Encoding.ASCII.GetBytes(base64EncodedImage);
Stream imageStream = TiffImageSplitter.ByteArrayToMemoryStream(imageAsByteStream);
// Image splitImage = TiffImageSplitter.getTiffImage(imageStream, 1);
TiffImageSplitter.tiff2PDF(imageStream);
}
2) method tiff2PDF should be like that
public static void tiff2PDF(Stream imageByteStream)
{
PdfDocument doc = new PdfDocument();
int pageCount = getPageCount(imageByteStream);
for (int i = 0; i < pageCount; i++)
{
PdfPage page = new PdfPage();
Image img = getTiffImage(imageByteStream, i); //<---HERE WAS ANOTHER ERROR, LOOK AT i
XImage imgFrame = XImage.FromGdiPlusImage(img);
3)
public static MemoryStream ByteArrayToMemoryStream(byte[] bytestream)
{
MemoryStream stream = new MemoryStream(bytestream);
//stream.Write(bytestream, 0, bytestream.Length);
return stream;
}
In my scenario I have 3 or more multi-page tiff images which I need to merge into a single tiff image.
Below is the the code I have tried. It merges in to a single tiff image but only with first page of all tiff images.
private static void MergeTiff(string[] sourceFiles)
{
string[] sa = sourceFiles;
//get the codec for tiff files
ImageCodecInfo info = null;
foreach (ImageCodecInfo ice in ImageCodecInfo.GetImageEncoders())
if (ice.MimeType == "image/tiff")
info = ice;
//use the save encoder
Encoder enc = Encoder.SaveFlag;
EncoderParameters ep = new EncoderParameters(1);
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
Bitmap pages = null;
int frame = 0;
foreach (string s in sa)
{
if (frame == 0)
{
MemoryStream ms = new MemoryStream(File.ReadAllBytes(Path.Combine(Environment.CurrentDirectory, #"C:\Data_Warehouse\SVNRepository\CD.BNS.W5555.LT45555C.D180306.T113850.Z0101\", s)));
pages = (Bitmap)Image.FromStream(ms);
var appDataPath = #"C:\Data_Warehouse\SVNRepository\Tiffiles\";
var filePath = Path.Combine(appDataPath, Path.GetRandomFileName() + ".tif");
//save the first frame
pages.Save(filePath, info, ep);
}
else
{
//save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
try
{
MemoryStream mss = new MemoryStream(File.ReadAllBytes(Path.Combine(Environment.CurrentDirectory, #"C:\Data_Warehouse\SVNRepository\CD.BNS.W5555.LT45555C.D180306.T113850.Z0101\", s)));
Bitmap bm = (Bitmap)Image.FromStream(mss);
pages.SaveAdd(bm, ep);
}
catch (Exception e)
{
//LogError(e, s);
}
}
if (frame == sa.Length - 1)
{
//flush and close.
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
pages.SaveAdd(ep);
}
frame++;
}
}
I need to join multiple tiff images with all pages from each tiff image. Please advise!
Thanks
EDIT: Updated from below answer
if (frame == 0)
{
MemoryStream ms = new MemoryStream(File.ReadAllBytes(Path.Combine(Environment.CurrentDirectory, #"C:\OMTest\Working\", s)));
pages = (Bitmap)Image.FromStream(ms);
var appDataPath = #"C:\Data_Warehouse\SVNRepository\Tiffiles\";
var filePath = Path.Combine(appDataPath, Path.GetRandomFileName() + ".tif");
//save the first frame
pages.Save(filePath, info, ep);
//Save the second frame if any
int frameCount1 = pages.GetFrameCount(FrameDimension.Page);
if (frameCount1 > 1)
{
for (int i = 1; i < frameCount1; i++)
{
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
pages.SelectActiveFrame(FrameDimension.Page, i);
pages.SaveAdd(pages, ep);
}
}
}
else
{
//save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
try
{
MemoryStream mss = new MemoryStream(File.ReadAllBytes(Path.Combine(Environment.CurrentDirectory, #"C:\OMTest\Working\", s)));
Bitmap bm = (Bitmap)Image.FromStream(mss);
int frameCount = bm.GetFrameCount(FrameDimension.Page);
for (int i = 0; i < frameCount; i++)
{
bm.SelectActiveFrame(FrameDimension.Page, i);
pages.SaveAdd(bm, ep);
}
}
catch (Exception e)
{
//LogError(e, s);
}
}
You need to select the active frame to ensure you are getting all pages on the TIFF. In your code you need to get the count of frames and loop through these.
The code in your else block might look something like this:
MemoryStream mss = new MemoryStream(File.ReadAllBytes(Path.Combine(Environment.CurrentDirectory, #"C:\Data_Warehouse\SVNRepository\CD.BNS.W5555.LT45555C.D180306.T113850.Z0101\", s)));
Bitmap bm = (Bitmap)Image.FromStream(mss);
int frameCount = bm.GetFrameCount(FrameDimension.Page);
for(int i=0;i<frameCount;i++){
bm.SelectActiveFrame(FrameDimension.Page, i);
pages.SaveAdd(bm, ep);
}
You may have to tweak it as I haven't tested it.
The given code works great to merge single-page TIFF files into a single multi-page TIFF, however, if there are multi-page TIFF files as sources, it will only merge their first page in the resulting TIFF file: the other ones will be discarded.
Since we couldn't find any working samples that could work around this issue, we ended up coding a small C# helper class, which later became a full-fledged multi-platform console application written in .NET Core 2 and C#. We called the project MergeTIFF and we released the whole source code on GitHub under GNU v3 license, so that everyone else can use it as well; we also released the binaries for Windows and Linux (32-bit and 64-bit).
Here's the relevant excerpt of the C# code:
using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
namespace MergeTiff.NET
{
/// <summary>
/// A small helper class to handle TIFF files
/// </summary>
public static class TiffHelper
{
/// <summary>
/// Merges multiple TIFF files (including multipage TIFFs) into a single multipage TIFF file.
/// </summary>
public static byte[] MergeTiff(params byte[][] tiffFiles)
{
byte[] tiffMerge = null;
using (var msMerge = new MemoryStream())
{
//get the codec for tiff files
ImageCodecInfo ici = null;
foreach (ImageCodecInfo i in ImageCodecInfo.GetImageEncoders())
if (i.MimeType == "image/tiff")
ici = i;
Encoder enc = Encoder.SaveFlag;
EncoderParameters ep = new EncoderParameters(1);
Bitmap pages = null;
int frame = 0;
foreach (var tiffFile in tiffFiles)
{
using (var imageStream = new MemoryStream(tiffFile))
{
using (Image tiffImage = Image.FromStream(imageStream))
{
foreach (Guid guid in tiffImage.FrameDimensionsList)
{
//create the frame dimension
FrameDimension dimension = new FrameDimension(guid);
//Gets the total number of frames in the .tiff file
int noOfPages = tiffImage.GetFrameCount(dimension);
for (int index = 0; index < noOfPages; index++)
{
FrameDimension currentFrame = new FrameDimension(guid);
tiffImage.SelectActiveFrame(currentFrame, index);
using (MemoryStream tempImg = new MemoryStream())
{
tiffImage.Save(tempImg, ImageFormat.Tiff);
{
if (frame == 0)
{
//save the first frame
pages = (Bitmap)Image.FromStream(tempImg);
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.MultiFrame);
pages.Save(msMerge, ici, ep);
}
else
{
//save the intermediate frames
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.FrameDimensionPage);
pages.SaveAdd((Bitmap)Image.FromStream(tempImg), ep);
}
}
frame++;
}
}
}
}
}
}
if (frame >0)
{
//flush and close.
ep.Param[0] = new EncoderParameter(enc, (long)EncoderValue.Flush);
pages.SaveAdd(ep);
}
msMerge.Position = 0;
tiffMerge = msMerge.ToArray();
}
return tiffMerge;
}
}
}

I am making a function where I pass an Image and that will compress the image and return that image object. Following is my code:
public Image CompressImage(Image img)
{
ImageCodecInfo jpegCodec = null;
EncoderParameter imageQualitysParameter = new EncoderParameter(
System.Drawing.Imaging.Encoder.Quality, 50L);
ImageCodecInfo[] alleCodecs = ImageCodecInfo.GetImageEncoders();
EncoderParameters codecParameter = new EncoderParameters(1);
codecParameter.Param[0] = imageQualitysParameter;
for (int i = 0; i < alleCodecs.Length; i++)
{
if (alleCodecs[i].MimeType == "image/jpeg")
{
jpegCodec = alleCodecs[i];
break;
}
}
Image img1;
using (Stream memory = new MemoryStream())
{
img.Save(memory, jpegCodec, codecParameter);
img1 = Image.FromStream(memory);
memory.Close();
memory.Dispose();
}
return img1;
}
But When I am saving it in the memory stream, it is showing error
An unhandled exception of type 'System.ArgumentException' occurred in EnexolImageConversionApp.exe
Additional information: Parameter is not valid.
on line
img.Save(memory, jpegCodec, codecParameter);
Try this code - it selects proper ImageCodecInfo by comparing ImageFormat.Guid and ImageCodecInfo.FormatID:
using System.Drawing.Imaging;
using System.IO;
public static byte[] SaveImageToByteArray(Image image, int jpegQuality = 90)
{
using (var ms = new MemoryStream())
{
var jpegEncoder = GetEncoder(ImageFormat.Jpeg);
var encoderParameters = new EncoderParameters(1);
encoderParameters.Param[0] = new EncoderParameter(Encoder.Quality, (long)jpegQuality);
image.Save(ms, jpegEncoder, encoderParameters);
return ms.ToArray();
}
}
private static ImageCodecInfo GetEncoder(ImageFormat format)
{
var codecs = ImageCodecInfo.GetImageDecoders();
foreach (ImageCodecInfo codec in codecs)
{
if (codec.FormatID == format.Guid)
{
return codec;
}
}
return null;
}
Last step will be loading image again from received byte array.
For better issue understanding please provide exception details, including stacktrace.

EDIT : I modified the code as below, now the image is saving without any exception! Thanks! but another problem here. the file size is not getting reduced. which mean my while loop can never exit. please help and thanks again.
using (MemoryStream ms = new MemoryStream(File.ReadAllBytes(realpath)))
{
using (Image FullsizeImage = Image.FromStream(ms))
{
//code here
int fileSize = (int)new System.IO.FileInfo(realpath).Length;

{
SaveJpeg(realpath, FullsizeImage, 85L);
fileSize = (int)new System.IO.FileInfo(realpath).Length;
}
}
}
Can someone help me please, my problem is not solved yet :(
Because you're disposing an image object.
public static void SaveJpeg(string path, Image img)
{
Image NewImage = img;
img.Dispose(); <------- Here
...
}
EDIT: Method Image.FromFile file opens a stream and that file wont be closed till your method is not terminated. Try to use MemoryStream.
using (MemoryStream ms = new MemoryStream(File.ReadAllBytes(realPath)))
{
using (Image img = Image.FromStream(ms))
{
ImageCodecInfo myImageCodecInfo;
Encoder myEncoder;
EncoderParameter myEncoderParameter;
EncoderParameters myEncoderParameters;
myImageCodecInfo = GetEncoderInfo("image/jpeg");
myEncoder = Encoder.Quality;
myEncoderParameters = new EncoderParameters(1);
myEncoderParameter = new EncoderParameter(myEncoder, 85L);
myEncoderParameters.Param[0] = myEncoderParameter;
img.Save(realPath, myImageCodecInfo, myEncoderParameters);
}
}
