Convert PDF to TIFF using ImageMagick & C#

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.

Dumping SQL table to .csv C#

I am trying to implement a script in my application that will dump the entire contents (for now, but I am trying to write the code so that I can easily customize it to only grab certain columns) of a sql db (running ms sql server express 2014) to a .csv file.
Here is the code I have written currently:
public void doCsvWrite(string timeStamp){
try {
//specify file name of log file (csv).
string newFileName = "C:/TestDirectory/DataExport-" + timeStamp + ".csv";
//check to see if file exists, if not create an empty file with the specified file name.
if (!File.Exists(newFileName)) {
FileStream fs = new FileStream(newFileName, FileMode.CreateNew);
fs.Close();
//define header of new file, and write header to file.
string csvHeader = "ITEM1,ITEM2,ITEM3,ITEM4,ITEM5";
using (FileStream fsWHT = new FileStream(newFileName, FileMode.Append, FileAccess.Write))
using(StreamWriter swT = new StreamWriter(fsWHT))
{
swT.WriteLine(csvHeader.ToString());
}
}
//set up connection to database.
SqlConnection myDEConnection;
String cDEString = "Data Source=localhost\\NAMEDPIPE;Initial Catalog=db;User Id=user;Password=pwd";
String strDEStatement = "SELECT * FROM table";
try
{
myDEConnection = new SqlConnection(cDEString);
}
catch (Exception ex)
{
//error handling here.
return;
}
try
{
myDEConnection.Open();
}
catch (Exception ex)
{
//error handling here.
return;
}
SqlDataReader reader = null;
SqlCommand myDECommand = new SqlCommand(strDEStatement, myDEConnection);
try
{
reader = myDECommand.ExecuteReader();
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
if(reader["Column1"].ToString() == "") {
//does nothing if the current line is "bugged" (containing no values at all, typically happens after reboot of 3rd party equipment).
}
else {
//grab relevant tag data and set the csv line for the current row.
string csvDetails = reader["Column1"] + "," + reader["Column2"] + "," + String.Format("{0:0.0}", reader["Column3"]) + "," + String.Format("{0:0.000}", reader["Column4"]) + "," + reader["Column5"];
using (FileStream fsWDT = new FileStream(newFileName, FileMode.Append, FileAccess.Write))
using(StreamWriter swDT = new StreamWriter(fsWDT))
{
//write csv line to file.
swDT.WriteLine(csvDetails.ToString());
}
}
}
}
}
catch (Exception ex)
{
//error handling here.
myDEConnection.Close();
return;
}
myDEConnection.Close();
}
catch (Exception ex)
{
//error handling here.
MessageBox.Show(ex.Message);
}
}
Now, this was working fine when I was using it with a 3rd party SQLite-based database, but the output I'm getting after modifing this to my MSSQL db looks something like this (ITEM1 is the primary key, a standard auto-incrementing ID-field):
ITEM1,ITEM2,ITEM3,ITEM4,ITEM5
1,row1_item2,row1_item3,row1_item4,row1_item5
1,row1_item2,row1_item3,row1_item4,row1_item5
1,row1_item2,row1_item3,row1_item4,row1_item5
1,row1_item2,row1_item3,row1_item4,row1_item5
1,row1_item2,row1_item3,row1_item4,row1_item5
1,row1_item2,row1_item3,row1_item4,row1_item5
2,row2_item2,row2_item3,row2_item4,row2_item5
2,row2_item2,row2_item3,row2_item4,row2_item5
2,row2_item2,row2_item3,row2_item4,row2_item5
2,row2_item2,row2_item3,row2_item4,row2_item5
2,row2_item2,row2_item3,row2_item4,row2_item5
3,row3_item2,row3_item3,row3_item4,row3_item5
3,row3_item2,row3_item3,row3_item4,row3_item5
3,row3_item2,row3_item3,row3_item4,row3_item5
3,row3_item2,row3_item3,row3_item4,row3_item5
....
So it seems that it writes several entries of the same row, where I would just like one single line each row. Any suggestions?
Thanks in advance.
edit: Thanks everyone for your answers!

The for loop isn't needed in the section below. Because it loops from 0 to FieldCount I assume the loop was originally meant to append the text from each column together but inside the loop there's a single line that concatenates the text and assigns it to csvDetails.
try
{
reader = myDECommand.ExecuteReader();
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
if(reader["Column1"].ToString() == "") {
//does nothing if the current line is "bugged" (containing no values at all, typically happens after reboot of 3rd party equipment).
}
else {
//grab relevant tag data and set the csv line for the current row.
string csvDetails = reader["Column1"] + "," + reader["Column2"] + "," + String.Format("{0:0.0}", reader["Column3"]) + "," + String.Format("{0:0.000}", reader["Column4"]) + "," + reader["Column5"];
using (FileStream fsWDT = new FileStream(newFileName, FileMode.Append, FileAccess.Write))
using(StreamWriter swDT = new StreamWriter(fsWDT))
{
//write csv line to file.
swDT.WriteLine(csvDetails.ToString());
}
}
}
}
}

Usually, we use specialy designed export/import utilites for dumping data.
However, if you have to implement you own routine I suggest decomposing.
private static IEnumerable<IDataRecord> SourceData(String sql) {
using (SqlConnection con = new SqlConnection(ConnectionStringHere)) {
con.Open();
using (SqlCommand q = new SqlCommand(sql, con)) {
using (var reader = q.ExecuteReader()) {
while (reader.Read()) {
//TODO: you may want to add additional conditions here
yield return reader;
}
}
}
}
}
private static IEnumerable<String> ToCsv(IEnumerable<IDataRecord> data) {
foreach (IDataRecord record in data) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < record .FieldCount; ++i) {
String chunk = Convert.ToString(record .GetValue(0));
if (i > 0)
sb.Append(',');
if (chunk.Contains(',') || chunk.Contains(';'))
chunk = "\"" + chunk.Replace("\"", "\"\"") + "\"";
sb.Append(chunk);
}
yield return sb.ToString();
}
}
Having SourceData and ToCsv you can easily implement
private static void WriteMyCsv(String fileName) {
var source = SourceData("SELECT * FROM table");
File.WriteAllLines(fileName, ToCsv(source));
}

You have a for loop which is looping over the fieldcount.
for (int i = 0; i < reader.FieldCount; i++)
I think it will work if you remove the loop as you don't need to iterate through the columns.

it happens because output placed inside for-loop
for (int i = 0; i < reader.FieldCount; i++)
and every record repeats FieldCount-times

Complete example. Verified working .NET 4.8, May 22. Code simplified for demo.
Why the DataTable ? Under circumstances it is useful. If you converting hundreds of files at once and multi threading - it works as large buffer + you can do pretty complex data mangling at the same time - should you need it.
UNFORTUNATELY - Microsoft trying to detect the column types and if your data not comply with the mechanism it ends with hard to correct errors. In that case use the second solution.
// Get the data from SQLite
SqliteConnection SQLiDataCon = new SqliteConnection(#"Data Source=c:\sqlite.db3");
SQLiDataCon.Open();
SqliteDataReader SQLiDtaReader = new SqliteCommand(#"SELECT * FROM stats;", SQLiDataCon).ExecuteReader();
// Load data to DataTable
DataTable csvTable = new DataTable();
csvTable.Load(SQLiDtaReader);
// Get "one" string with column names
string csvFields = #"""" + String.Join(#""",""",csvTable.Columns.Cast<DataColumn>().Select(dc => dc.ColumnName).ToArray()) + #"""";
// Prep "in memory the entire content of the CSV"
StringBuilder csvString = new StringBuilder();
// Write the header in
csvString.AppendLine(csvFields);
// Write the rows in
foreach (DataRow dr in csvTable.Rows)
{
csvString.AppendLine(#"""" + String.Join(#""",""", dr.ItemArray) + #"""");
}
// Save to file
StreamWriter csvFile = new StreamWriter(#"c:\stats.csv");
csvFile.Write(csvString);
Without DataTable.
// SQLITE
SqliteConnection SQLiDataCon = new SqliteConnection(#"Data Source=c:\sqlite.db3");
SQLiDataCon.Open();
StringBuilder csvString = new StringBuilder();
StreamWriter csvFile;
Object[] csvRow;
SqliteDataReader SQLiDtaReader = new SqliteCommand(#"SELECT * FROM sometable;", SQLiDataCon).ExecuteReader();
// CSV HEADER
csvString.AppendLine(#"""" + String.Join(#""",""", SQLiDtaReader.GetSchemaTable().AsEnumerable().Select(dr => dr.Field<string>("ColumnName")).ToArray<string>()) + #"""");
// CSV BODY
while (SQLiDtaReader.Read())
{
SQLiDtaReader.GetValues(csvRow = new Object[SQLiDtaReader.FieldCount]);
csvString.AppendLine(#"""" + String.Join(#""",""",csvRow ) + #"""");
}
// WRITE IT
csvFile = new StreamWriter(#"C:\somecsvfile.csv");
csvFile.Write(csvString);

Here's how you debug scripts in SSIS
With the code open, put a breakpoint
Close the code
Run the package
When the script starts running, it will open up a code window and you can walk through the code step by step

csv modify file

I am a bit in a pickle regarding a consolidation application we are using in our company. We create a csv file from an progress database this csv file has 14 columns and NO header.
The CSV file contains payments (around 173 thousand rows). Most of these rows are the same except for the column amount (last column)
Example:
2014;MONTH;;SC;10110;;;;;;;;EUR;-6500000
2014;01;;SC;10110;;;;;;;;EUR;-1010665
2014;01;;LLC;11110;;;;;;;;EUR;-6567000
2014;01;;SC;10110;;;;;;;;EUR;-1110665
2014;01;;LLC;11110;;;;;;;;EUR;65670.00
2014;01;;SC;10110;;;;;;;;EUR;-11146.65
(around 174000 rows)
As you can see some of these lines are the same except for the amount column. What i need is to sort all rows, add up the amount and save one unique row instead of 1100 rows with different amounts.
My coding skills are failing me to get the job done within a certain timeframe, maybe one of you can push me in the right direction solving this problem.
Example code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string input = File.ReadAllText(#"c:\temp\test.txt");
string inputLine = "";
StringReader reader = new StringReader(input);
List<List<string>> data = new List<List<string>>();
while ((inputLine = reader.ReadLine()) != null)
{
if (inputLine.Trim().Length > 0)
{
string[] inputArray = inputLine.Split(new char[] { ';' });
data.Add(inputArray.ToList());
}
}
//sort data by every column
for (int sortCol = data[0].Count() - 1; sortCol >= 0; sortCol--)
{
data.OrderBy(x => x[sortCol]);
}
//delete duplicate rows
for (int rowCount = data.Count - 1; rowCount >= 1; rowCount--)
{
Boolean match = true;
for (int colCount = 0; colCount < data[rowCount].Count - 2; colCount++)
{
if(data[rowCount][colCount] != data[rowCount - 1][colCount])
{
match = false;
break;
}
}
if (match == true)
{
decimal previousValue = decimal.Parse(data[rowCount - 1][data[rowCount].Count - 1]);
decimal currentValue = decimal.Parse(data[rowCount][data[rowCount].Count - 1]);
string newStrValue = (previousValue + currentValue).ToString();
data[rowCount - 1][data[rowCount].Count - 1] = newStrValue;
data.RemoveAt(rowCount);
}
}
string output = string.Join("\r\n",data.AsEnumerable()
.Select(x => string.Join(";",x.Select(y => y).ToArray())).ToArray());
File.WriteAllText(#"c:\temp\test1.txt",output);
}
}
}

Read the CSV file line by line, and build an in-memory dictionary in which you keep the totals (and other information you require). As most of the lines belong to the same key, it will probably not cause out of memory issues. Afterwards, generate a new CSV based on the information in the dictionary.

As I interpret your question, your problem and the solution you are asking for are how to take your input that are in the form of
#"2014;MONTH;;SC;10110;;;;;;;;EUR;-6500000
2014;01;;SC;10110;;;;;;;;EUR;-1010665
2014;01;;LLC;11110;;;;;;;;EUR;-6567000
2014;01;;SC;10110;;;;;;;;EUR;-1110665
2014;01;;LLC;11110;;;;;;;;EUR;65670.00
2014;01;;SC;10110;;;;;;;;EUR;-11146.65"
Get the last column and then sum it up? If so this is actually very easy to do with something like this
public static void Main()
{
string input = #"2014;MONTH;;SC;10110;;;;;;;;EUR;-6500000
2014;01;;SC;10110;;;;;;;;EUR;-1010665
2014;01;;LLC;11110;;;;;;;;EUR;-6567000
2014;01;;SC;10110;;;;;;;;EUR;-1110665
2014;01;;LLC;11110;;;;;;;;EUR;65670.00
2014;01;;SC;10110;;;;;;;;EUR;-11146.65";
var rows = input.Split('\n');
decimal totalValue = 0m;
foreach(var row in rows)
{
var transaction = row.Substring(row.LastIndexOf(';') +1);
decimal val = 0m;
if(decimal.TryParse(transaction, out val))
totalValue += val;
}
Console.WriteLine(totalValue);
}
But maybe I have misunderstood what you were asking for?

Sorry answering my post so late but this is my final solution
Replacing all " characters and write the output to the stream writer. (going from 25mb to a 15mb file.). Than copy my CSV file to the SQL server so i can bulk insert. After my insert i just query the table and read / write the result set to a new file. My new file is only +/-700KB!
The Filldata() method is filling a datagridview in my application so you can review the result instead of opening the file in excel.
I am new with C#, i am currently writing a new solution to query the csv file directly or in memory and write it back to a new file.
Method1:
string line;
StreamWriter sw = new StreamWriter(insertFile);
using (StreamReader sr = new StreamReader(sourcePath))
{
while ((line = sr.ReadLine()) != null)
{
sw.WriteLine(line.Replace("\"", ""));
}
sr.Close();
sw.Close();
sr.Dispose();
sw.Dispose();
File.Copy(insertFile, #"\\SQLSERVER\C$\insert.csv");
}
Method2:
var destinationFile = #"c:\insert.csv";
var querieImportCSV = "BULK INSERT dbo.TABLE FROM '" + destinationFile + "' WITH ( FIELDTERMINATOR = ';', ROWTERMINATOR = '\n', FIRSTROW = 1)";
var truncate = #"TRUNCATE TABLE dbo.TABLE";
string queryResult =
#"SELECT [Year]
,[Month]
,[Week]
,[Entity]
,[Account]
,[C11]
,[C12]
,[C21]
,[C22]

,[C4]
,[CTP]
,[VALUTA]
,SUM(AMOUNT) as AMOUNT

var conn = new SqlConnection(connectionString);
conn.Open();
SqlCommand commandTruncate = new SqlCommand(truncate, conn);
commandTruncate.ExecuteNonQuery();
SqlCommand commandInsert = new SqlCommand(querieImportCSV, conn);
SqlDataReader readerInsert = commandInsert.ExecuteReader();
readerInsert.Close();
FillData();
SqlCommand commandResult = new SqlCommand(queryResult, conn);
SqlDataReader readerResult = commandResult.ExecuteReader();
StringBuilder sb = new StringBuilder();
while (readerResult.Read())
{
sb.Append(readerResult["Year"] + ";" + readerResult["Month"] + ";" + readerResult["Week"] + ";" + readerResult["Entity"] + ";" + readerResult["Account"] + ";" +
readerResult["C11"] + ";" + readerResult["C12"] + ";" + readerResult["C21"] + ";" + readerResult["C22"] + ";" + readerResult["C3"] + ";" + readerResult["C4"] + ";" +
readerResult["CTP"] + ";" + readerResult["Valuta"] + ";" + readerResult["Amount"] + ";" + readerResult["CURRENCY_ORIG"] + ";" + readerResult["AMOUNTEXCH"] + ";" + readerResult["AGENTCODE"]);
}
sb.Replace("\"","");
StreamWriter sw = new StreamWriter(homedrive);
sw.WriteLine(sb);
readerResult.Close();
conn.Close();
sw.Close();
sw.Dispose();

Gedcom Reader for C#

Does anyone know of a good class to read in .ged files
Gedcom is a file format that is used to store genealogical information.
My goal is to write something that would let me import a ged file and export a .dot file for graphviz so that I can make a visual representation of a family tree
thanks if you can help

Heres my best attempt so far.
It seems to be working for what i need though its defiently not full proof ( then again my family tree is rather large and that adds some complexity)
please let me know if you think i could make anything more elequient

There is a very pretty one at Codeplex: FamilyShow (a WPF showcase). It imports/exports GEDCOM 5.5 and there is source.

I would actually have been surprised if there wasn't at least the beginnings of one. I found Gedcom.NET (sourceforge) quite easily

I'd be fairly surprised if there was a C# reader for this format available on the web, given that it's a fairly specialized format. On the upside, the format looks to be pretty straightforward to read if you need to create your own reader. I would suggest going down that path and coming back to SO if you have specific questions about the implementation. Take a look at the System.IO.StreamReader class; it's trivial to read in a file line-by-line that way, and parsing the individual lines should be simple as well.
Good luck!

I found a fresh project GedcomParser.
