# .Net library and tool to work with PDF files
## Usage
### VAR.PdfTools
Add the resulting assembly as reference in your projects, and this line on code:
```csharp
using VAR.PdfTools;
```
Then extract the contents of a data column using:
```csharp
var columnData = new List<string>();
PdfDocument doc = PdfDocument.Load("document.pdf");
foreach (PdfDocumentPage page in doc.Pages)
{
PdfTextExtractor extractor = new PdfTextExtractor(page);
columnData.AddRange(extractor.GetColumnAsStrings("Column"));
}
```
Or the content of a field (text on the right of the indicated text):
```csharp
var fieldData = new List<string>();
PdfDocument doc = PdfDocument.Load("document.pdf");
foreach (PdfDocumentPage page in doc.Pages)
{
PdfTextExtractor extractor = new PdfTextExtractor(page);
fieldData.Add(extractor.GetFieldAsString(txtFieldName.Text));
}
```
### VAR.PdfTools.Workbench
It is a simple Windows.Forms application, to test basic funcitionallity of the library.
## Building
A Visual Studio 2015 and 2010 solutions are provided. Simply, click build on the IDE.
A .nuget package can be build using:
VAR.PdfTools\Build.NuGet.cmd

Microsoft ResX Schema
Version 2.0
The primary goals of this format is to allow a simple XML format
that is mostly human readable. The generation and parsing of the
various data types are done through the TypeConverter classes
associated with the data types.
Example:
... ado.net/XML headers & schema ...
<resheader name="resmimetype">text/microsoft-resx</resheader>
<resheader name="version">2.0</resheader>
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
<value>[base64 mime encoded serialized .NET Framework object]</value>
</data>
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
<comment>This is a comment</comment>
</data>
There are any number of "resheader" rows that contain simple
name/value pairs.
Each data row contains a name, and value. The row also contains a
type or mimetype. Type corresponds to a .NET class that support
text/value conversion through the TypeConverter architecture.
Classes that don't support this are serialized and stored with the
mimetype set.
The mimetype is used for serialized objects, and tells the
ResXResourceReader how to depersist the object. This is currently not
extensible. For a given mimetype the value must be set accordingly:
Note - application/x-microsoft.net.object.binary.base64 is the format
that the ResXResourceWriter will generate, however the reader can
read any of the formats listed below.
mimetype: application/x-microsoft.net.object.binary.base64
value : The object must be serialized with
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.soap.base64
value : The object must be serialized with
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.bytearray.base64
value : The object must be serialized into a byte array
: using a System.ComponentModel.TypeConverter
: and then encoded with base64 encoding.
