I have an existing program that does some processing a .pdf file and splitting it into multiple .pdf files based on looking for barcodes on the pages.
The program uses ImageMagick and C#.
I want to change it from outputting pdfs to outputting tifs. Look for the comment in the code below for where I would guess the change would be made.
I included the ImageMagick tag because someone might offer a commandline option that someone else can help me convert to C#.
private void BurstPdf(string bigPdfName, string targetfolder)
{
bool outputPdf = true; // change to false to output tif.
string outputExtension = "";
var settings = new MagickReadSettings { Density = new Density(200) };
string barcodePng = Path.Combine("C:\TEMP", "tmp.png");
using (MagickImageCollection pdfPageCollection = new MagickImageCollection())
{
pdfPageCollection.Read(bigPdfName, settings);
int inputPageCount = 0;
int outputPageCount = 0;
int outputFileCount = 0;
MagickImageCollection resultCollection = new MagickImageCollection();
string barcode = "";
string resultName = "";
IBarcodeReader reader = new BarcodeReader();
reader.Options.PossibleFormats = new List<BarcodeFormat>();
reader.Options.PossibleFormats.Add(BarcodeFormat.CODE_39);
reader.Options.TryHarder = false;
foreach (MagickImage pdfPage in pdfPageCollection)
{
MagickGeometry barcodeArea = getBarCodeArea(pdfPage);
IMagickImage barcodeImg = pdfPage.Clone();
barcodeImg.ColorType = ColorType.Bilevel;
barcodeImg.Depth = 1;
barcodeImg.Alpha(AlphaOption.Off);
barcodeImg.Crop(barcodeArea);
barcodeImg.Write(barcodePng);
inputPageCount++;
using (var barcodeBitmap = new Bitmap(barcodePng))
{
var result = reader.Decode(barcodeBitmap);
if (result != null)
{
// found a first page because it has bar code.
if (result.BarcodeFormat.ToString() == "CODE_39")
{
if (outputFileCount != 0)
{
// write out previous pages.
if (outputPdf) {
outputExtension = ".pdf";
} else {
// What do I put here to output a g4 compressed tif?
outputExtension = ".tif";
}
resultName = string.Format("{0:D4}", outputFileCount) + "-" + outputPageCount.ToString() + "-" + barcode + outputExtension;
resultCollection.Write(Path.Combine(targetfolder, resultName));
resultCollection = new MagickImageCollection();
}
barcode = standardizePhysicalBarCode(result.Text);
outputFileCount++;
resultCollection.Add(pdfPage);
outputPageCount = 1;
}
else
{
Console.WriteLine("WARNING barcode is not of type CODE_39 so something is wrong. check page " + inputPageCount + " of " + bigPdfName);
if (inputPageCount == 1)
{
throw new Exception("barcode not found on page 1. see " + barcodePng);
}
resultCollection.Add(pdfPage);
outputPageCount++;
}
}
else
{
if (inputPageCount == 1)
{
throw new Exception("barcode not found on page 1. see " + barcodePng);
}
resultCollection.Add(pdfPage);
outputPageCount++;
}
}
if (File.Exists(barcodePng))
{
File.Delete(barcodePng);
}
}
if (resultCollection.Count > 0)
{
if (outputPdf) {
outputExtension = ".pdf";
} else {
// What do I put here to output a g4 compressed tif?
outputExtension = ".tif";
}
resultName = string.Format("{0:D4}", outputFileCount) + "-" + outputPageCount.ToString() + "-" + barcode + outputExtension;
resultCollection.Write(Path.Combine(targetfolder, resultName));
outputFileCount++;
}
}
}
[EDIT] The above code is what I am using (which some untested modifications) to split a .pdf into other .pdfs. I want to know how to modify this code to output tiffs. I put a comment in the code where I think the change would go.
[EDIT] So encouraged by #fmw42 I just ran the code with the .tif extension enabled. Looks like it did convert to a .tif, but the tif is not compressed. I am surprised that IM just configures the output based on the extension name of the file. Handy I guess, but just seems a little loose.
[EDIT] I figured it out. Although counter-intuitive ones sets the compression on the read of the file. I am reading a .pdf but I set the compression to Group for like this:
var settings = new MagickReadSettings { Density = new Density(200), Compression = CompressionMethod.Group4 };
The thing I learned was that simply naming the output file .tif tells IM to output a tif. That is a handy way to do it, but it just seems sloppy.
I am Converting multiple PDF to multiple tif images using GdPicture.NET. (using this sample code in a Windows Forms Application)
I need to improve the speed of this process to suit it for thousands of PDF files.
Below is a sample method I used to implement a threading. However this mix the pdf pages.
public void ThreadRun(string pdFilFullName, string batchDir){
GdPictureStatus status = new GdPictureStatus();
GdPictureImaging oGdPictureImaging = new GdPictureImaging();
GdPicturePDF oGdPicturePDF = new GdPicturePDF();
status = oGdPicturePDF.LoadFromFile(pdFilFullName, false);
for (int i = 1; i <= oGdPicturePDF.GetPageCount(); i++)
{
//select page
oGdPicturePDF.SelectPage(i);
//render selected page to GdPictureImage identifier
int rasterizedPageID = oGdPicturePDF.RenderPageToGdPictureImageEx(200.0f, true);
if (i == 1 || i < 10)
{
padding = "00";
}
else if (i == 10 || i < 100)
{
padding = "0";
}
else
{
padding = string.Empty;
}
//Set Image file name
filePath = batchDir + "\\" + padding + i + ".tif";
// Converting to black and White
oGdPictureImaging.FxBlackNWhite(rasterizedPageID, BitonalReduction.Stucki);
// Converting to Single pixel
oGdPictureImaging.ConvertTo1BppAT(rasterizedPageID);
// Saving each page of the PDF file to single TIFF image
status = oGdPictureImaging.SaveAsTIFF(rasterizedPageID, filePath, false, tiffType);
oGdPictureImaging.ReleaseGdPictureImage(rasterizedPageID);
//check for page errors
if (status != GdPictureStatus.OK)
{
Console.WriteLine("page error: " + pdFilFullName + status.ToString());
}
Application.DoEvents();
}
}
protected void pdftotiff(string filepath){
List<string> result = Directory.EnumerateFiles(filepath, "*.pdf", System.IO.SearchOption.TopDirectoryOnly).Union(Directory.EnumerateFiles(filepath, "*.tif", System.IO.SearchOption.TopDirectoryOnly)).ToList();
foreach(string file in result){
GdPicturePDF oGdPicturePDF = new GdPicturePDF();
GdPictureImaging oGdPictureImaging = new GdPictureImaging();
if ((_pdFileInfo.Name.Split('.')[1] != "tif") && (oGdPicturePDF.LoadFromFile(_pdFileInfo.FullName, false) == GdPictureStatus.OK))
{
batchDir = folderPath + "\\Batches\\" + _pdFileInfo.Name.Split('.')[0] + "." + batchDate.Substring(6, 2) + batchDate.Substring(4, 2);
batchname = _pdFileInfo.Name.Split('.')[0] + "." + batchDate.Substring(6, 2) + batchDate.Substring(4, 2);
if (!Directory.Exists(batchDir)){
Directory.CreateDirectory(batchDir);
}
Thread t = new Thread(() => ThreadRun(_pdFileInfo.FullName, batchDir));
t.Start();
}
}
Can you provide suggestion/samples.
Used Parallel.ForEach to process the pdf files like below.
List<string> result = Directory.EnumerateFiles(filepath, "*.pdf", System.IO.SearchOption.TopDirectoryOnly).Union(Directory.EnumerateFiles(filepath, "*.tif", System.IO.SearchOption.TopDirectoryOnly)).ToList();
Parallel.ForEach(result, new ParallelOptions { MaxDegreeOfParallelism=3}, file =>
{
try
{
GdPictureStatus status = new GdPictureStatus();
GdPictureImaging oGdPictureImaging = new GdPictureImaging();
GdPicturePDF oGdPicturePDF = new GdPicturePDF();
status = oGdPicturePDF.LoadFromFile(file, false);
if (status == GdPictureStatus.OK)
{
string batchDate = filepath.Substring(filepath.LastIndexOf("\\") + 1);
string padding = String.Empty;
string filePath = string.Empty;
FileInfo _pdFileInfo = new FileInfo(file);
string batchDir = filepath + "\\Batches\\" + _pdFileInfo.Name.Split('.')[0] + "." + batchDate.Substring(6, 2) + batchDate.Substring(4, 2);

if (i == 1 || i < 10)
{
padding = "00";
}
else if (i == 10 || i < 100)
{

}
else
{

The method below takes in some FileInfo of a certain pdf file and will then proceed to convert that pdf into bitmaps. This method works randomly it seems. Sometimes it will finish with no problems, other times it will fail at the using (Bitmap bmp = image.ToBitmap()) part. Once it hits that line I get a "Parameter is not valid" error. I have no clue how to fix this random error nor dissect it even further. Any help would be appreciated
static void ParseOutEachBitmap(FileInfo[] pdfFiles)
{
string BmpPath = "C:\\temp\\bmps\\";
if (!Directory.Exists(BmpPath))
{
Directory.CreateDirectory(BmpPath);
}
using (MagickImageCollection images = new MagickImageCollection())
{
MagickReadSettings settings = new MagickReadSettings();
settings.Density = new MagickGeometry(300, 300);
for (int p = 0; p < pdfFiles.Count(); p++)
{
images.Read(#"c:\temp\pdfs\" + pdfFiles[p].Name, settings);
int pageNumber = 1;
string pdfName = pdfFiles[p].Name;
foreach (MagickImage image in images)
{
using (Bitmap bmp = image.ToBitmap())
{
Console.WriteLine("PDF Filename: " + pdfName);
Console.WriteLine("Page Number: " + pageNumber + " of " + images.Count);
pageNumber++;
using (tessnet2.Tesseract tessocr = new tessnet2.Tesseract())
{
tessocr.GetThresholdedImage(bmp, System.Drawing.Rectangle.Empty).Save("c:\\temp\\bmps\\" + Guid.NewGuid().ToString() + ".bmp");
}
}
}
}
}
}
I have created these functions which I described in the question. However I think the way I did it is not the optimal way of doing it.
[HttpPost]
public ActionResult Create(FormCollection collection, string schooljaarparam, FlatONASAanbieder foa) {
if (ModelState.IsValid) {
// var r = new List<ViewDataUploadFilesResult>();
foreach (string file in Request.Files) {
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
continue;
//extensie nakijken. jpg, png, jpeg, of GIF.
if (MvcApplication.isImage(hpf.FileName)) {
//Image img = new Image();
string savedFileName = Path.Combine(
AppDomain.CurrentDomain.BaseDirectory + "uploads\\ONAS\\",
Path.GetFileName(hpf.FileName));
FileInfo fi = new FileInfo(savedFileName);
int i = 1;
while (fi.Exists) {
fi = new FileInfo(savedFileName.Substring(0, savedFileName.Length - Path.GetFileName(savedFileName).Length) + Path.GetFileNameWithoutExtension(savedFileName) + " (" + i++ + ") " + Path.GetExtension(savedFileName));
}
savedFileName = fi.DirectoryName + "\\" + fi.Name;
hpf.SaveAs(savedFileName);
using (Image Img = Image.FromFile(savedFileName)) {
//Size ThumbNailSize = NewImageSize(Img.Height, Img.Width, 79);
Size NewSize = VerkleinMaxHoogte(Img.Size, 79);
using (Image ImgThnail = new Bitmap(Img, NewSize.Width, NewSize.Height)) {
//string ss = savedFileName.Substring(0, savedFileName.Length - Path.GetFileName(savedFileName).Length) + Path.GetFileNameWithoutExtension(savedFileName) + "-thumb" + Path.GetExtension(savedFileName);
ImgThnail.Save(savedFileName + ".tmp", Img.RawFormat);
ImgThnail.Dispose();
}
Img.Dispose();
}
System.IO.File.Delete(savedFileName);
FileInfo f = new FileInfo(savedFileName + ".tmp");
f.MoveTo(savedFileName);
} else {
ModelState.AddModelError("ONAS_Logo", "Het geuploadde bestand is geen afbeelding. ");
}
//r.Add(new ViewDataUploadFilesResult() {
// Name = savedFileName,
// Length = hpf.ContentLength
//});
}
}
// return View("UploadedFiles", r);
return View();
}
[NonAction]
public Size VerkleinMaxHoogte(Size orig, double height) {
double tempval = height / orig.Height;
return new Size(Convert.ToInt32(tempval * orig.Width), Convert.ToInt32(height));
}
in global.asax
public static bool isImage(string s) {
if (s.EndsWith(".jpg", true, null) || s.EndsWith(".jpeg", true, null) || s.EndsWith(".gif", true, null) || s.EndsWith(".png", true, null)) {
return true;
}
return false;
}
so the way I do it:
I get the file from the browser
I check if it is an Image
I check if the file exists, and if so, change the filename accordingly
I save the file on disk (IO, slow)
I open the file as an image
I calculate the width and height with the VerkleinMaxHoogte method
I create the thumbnail and save it with a tmp extension
I delete the original file
I rename the thumbnail to the original file name (this is what I want)
How do I do it faster?
You can always use HttpPostedFile.InputStream and Image.FromStream method to combine #4 & #5. This will also eliminate #8 & #9.
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 solutions or code are there for converting an image to a PDF?
Easy with iTextSharp:
class Program
{
static void Main(string[] args)
{
Document document = new Document();
using (var stream = new FileStream("test.pdf", FileMode.Create, FileAccess.Write, FileShare.None))
{
PdfWriter.GetInstance(document, stream);
document.Open();
using (var imageStream = new FileStream("test.jpg", FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
var image = Image.GetInstance(imageStream);
document.Add(image);
}
document.Close();
}
}
}
iTextSharp does it pretty cleanly and is open source. Also, it has a very good accompanying book by the author which I recommend if you end up doing more interesting things like managing forms. For normal usage, there are plenty resources on mailing lists and newsgroups for samples of how to do common things.
EDIT: as alluded to in #Chirag's comment, #Darin's answer has code that definitely compiles with current versions.
Example usage:
public static void ImagesToPdf(string[] imagepaths, string pdfpath)
{
using(var doc = new iTextSharp.text.Document())
{
iTextSharp.text.pdf.PdfWriter.GetInstance(doc, new FileStream(pdfpath, FileMode.Create));
doc.Open();
foreach (var item in imagepaths)
{
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(item);
doc.Add(image);
}
}
}
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());
}
}
One we've had great luck with is PDFSharp (we use it for TIFF and Text to PDF conversion for hundreds of medical claims every day).
http://pdfsharp.com/PDFsharp/
Such task can be easily done with help of Docotic.Pdf library.
Here is a sample that creates PDF from given images (not only JPGs, actually):
public static void imagesToPdf(string[] images, string pdfName)
{
using (PdfDocument pdf = new PdfDocument())
{
for (int i = 0; i < images.Length; i++)
{
if (i > 0)
pdf.AddPage();
PdfPage page = pdf.Pages[i];
string imagePath = images[i];
PdfImage pdfImage = pdf.AddImage(imagePath);
page.Width = pdfImage.Width;
page.Height = pdfImage.Height;
page.Canvas.DrawImage(pdfImage, 0, 0);
}
pdf.Save(pdfName);
}
}
Disclaimer: I work for the vendor of the library.
If you want to do it in a cross-platform way, without any thirty part library,
or paying any license, you can use this code.
It takes an array of pictures (I think it only works only with jpg) with its sizes and return a pdf file, with one picture per page.
You have to create two files:
File Picture:
using System;
using System.Collections.Generic;
using System.Text;
namespace PDF
{
public class Picture
{
private byte[] data;
private int width;
private int height;
public byte[] Data { get => data; set => data = value; }
public int Width { get => width; set => width = value; }
public int Height { get => height; set => height = value; }
}
}
File PDFExport:
using System;
using System.Collections.Generic;
namespace PDF
{
public class PDFExport
{
private string company = "Your Company Here";
public sbyte[] createFile(List<Picture> pictures)
{
int N = (pictures.Count + 1) * 3;

not sure if you're looking for just free / open source solutions or considering commercial ones as well. But if you're including commercial solutions, there's a toolkit called EasyPDF SDK that offers an API for converting images (plus a number of other file types) to PDF. It supports C# and can be found here:
http://www.pdfonline.com/
The C# code would look as follows:
Printer oPrinter = new Printer();
ImagePrintJob oPrintJob = oPrinter.ImagePrintJob;
oPrintJob.PrintOut(imageFile, pdfFile);
To be fully transparent, I should disclaim that I do work for the makers of EasyPDF SDK (hence my handle), so this suggestion is not without some personal bias :) But feel free to check out the eval version if you're interested. Cheers!
I use Sautinsoft, its very simple:
SautinSoft.PdfMetamorphosis p = new SautinSoft.PdfMetamorphosis();
p.Serial="xxx";
p.HtmlToPdfConvertStringToFile("<html><body><img src=\""+filename+"\"></img></body></html>","output.pdf");
You may try to convert any Images to PDF using this code sample:
PdfVision v = new PdfVision();
ImageToPdfOptions options = new ImageToPdfOptions();
options.JpegQuality = 95;
try
{
v.ConvertImageToPdf(new string[] {inpFile}, outFile, options);
System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo(outFile) { UseShellExecute = true });
}
catch (Exception ex)
{
Console.WriteLine($"Error: {ex.Message}");
Console.ReadLine();
}
Or if you need to convert Image Class to PDF:
System.Drawing.Image image = Image.FromFile(#"..\..\image-jpeg.jpg");
string outFile = new FileInfo(#"Result.pdf").FullName;
PdfVision v = new PdfVision();
ImageToPdfOptions options = new ImageToPdfOptions();
options.PageSetup.PaperType = PaperType.Auto;
byte[] imgBytes = null;
using (MemoryStream ms = new System.IO.MemoryStream())
{
image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
imgBytes = ms.ToArray();
}
