 5 | Examples of how to using OpenGL via OpenTK in WPF applications
 6 | 
 7 | This solution contains two projects. One project shows the usage of OpenTK in WPF via a WindowsFormsHost and the other by using a Framebuffer object.
 8 | 
 9 | The Framebuffer-approach is a "pure"-WPF-approach, but the WinformsHost-approach is faster (32 vs 48fps).
10 | 
11 | Feel free to improve!

  4 |     Microsoft ResX Schema 
  5 |     
  6 |     Version 2.0
  7 |     
  8 |     The primary goals of this format is to allow a simple XML format 
  9 |     that is mostly human readable. The generation and parsing of the 
 10 |     various data types are done through the TypeConverter classes 
 11 |     associated with the data types.
 12 |     
 13 |     Example:
 14 |     
 15 |     ... ado.net/XML headers & schema ...
 16 |     <resheader name="resmimetype">text/microsoft-resx</resheader>
 17 |     <resheader name="version">2.0</resheader>
 18 |     <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
 19 |     <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
 20 |     <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
 21 |     <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
 22 |     <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
 23 |         <value>[base64 mime encoded serialized .NET Framework object]</value>
 24 |     </data>
 25 |     <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
 26 |         <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
 27 |         <comment>This is a comment</comment>
 28 |     </data>
 29 |                 
 30 |     There are any number of "resheader" rows that contain simple 
 31 |     name/value pairs.
 32 |     
 33 |     Each data row contains a name, and value. The row also contains a 
 34 |     type or mimetype. Type corresponds to a .NET class that support 
 35 |     text/value conversion through the TypeConverter architecture. 
 36 |     Classes that don't support this are serialized and stored with the 
 37 |     mimetype set.
 38 |     
 39 |     The mimetype is used for serialized objects, and tells the 
 40 |     ResXResourceReader how to depersist the object. This is currently not 
 41 |     extensible. For a given mimetype the value must be set accordingly:
 42 |     
 43 |     Note - application/x-microsoft.net.object.binary.base64 is the format 
 44 |     that the ResXResourceWriter will generate, however the reader can 
 45 |     read any of the formats listed below.
 46 |     
 47 |     mimetype: application/x-microsoft.net.object.binary.base64
 48 |     value   : The object must be serialized with 
 49 |             : System.Serialization.Formatters.Binary.BinaryFormatter
 50 |             : and then encoded with base64 encoding.
 51 |     
 52 |     mimetype: application/x-microsoft.net.object.soap.base64
 53 |     value   : The object must be serialized with 
 54 |             : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
 55 |             : and then encoded with base64 encoding.
 56 | 
 57 |     mimetype: application/x-microsoft.net.object.bytearray.base64
 58 |     value   : The object must be serialized into a byte array 
 59 |             : using a System.ComponentModel.TypeConverter
 60 |             : and then encoded with base64 encoding.

  4 |     Microsoft ResX Schema 
  5 |     
  6 |     Version 2.0
  7 |     
  8 |     The primary goals of this format is to allow a simple XML format 
  9 |     that is mostly human readable. The generation and parsing of the 
 10 |     various data types are done through the TypeConverter classes 
 11 |     associated with the data types.
 12 |     
 13 |     Example:
 14 |     
 15 |     ... ado.net/XML headers & schema ...
 16 |     <resheader name="resmimetype">text/microsoft-resx</resheader>
 17 |     <resheader name="version">2.0</resheader>
 18 |     <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
 19 |     <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
 20 |     <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
 21 |     <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
 22 |     <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
 23 |         <value>[base64 mime encoded serialized .NET Framework object]</value>
 24 |     </data>
 25 |     <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
 26 |         <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
 27 |         <comment>This is a comment</comment>
 28 |     </data>
 29 |                 
 30 |     There are any number of "resheader" rows that contain simple 
 31 |     name/value pairs.
 32 |     
 33 |     Each data row contains a name, and value. The row also contains a 
 34 |     type or mimetype. Type corresponds to a .NET class that support 
 35 |     text/value conversion through the TypeConverter architecture. 
 36 |     Classes that don't support this are serialized and stored with the 
 37 |     mimetype set.
 38 |     
 39 |     The mimetype is used for serialized objects, and tells the 
 40 |     ResXResourceReader how to depersist the object. This is currently not 
 41 |     extensible. For a given mimetype the value must be set accordingly:
 42 |     
 43 |     Note - application/x-microsoft.net.object.binary.base64 is the format 
 44 |     that the ResXResourceWriter will generate, however the reader can 
 45 |     read any of the formats listed below.
 46 |     
 47 |     mimetype: application/x-microsoft.net.object.binary.base64
 48 |     value   : The object must be serialized with 
 49 |             : System.Serialization.Formatters.Binary.BinaryFormatter
 50 |             : and then encoded with base64 encoding.
 51 |     
 52 |     mimetype: application/x-microsoft.net.object.soap.base64
 53 |     value   : The object must be serialized with 
 54 |             : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
 55 |             : and then encoded with base64 encoding.
 56 | 
 57 |     mimetype: application/x-microsoft.net.object.bytearray.base64
 58 |     value   : The object must be serialized into a byte array 
 59 |             : using a System.ComponentModel.TypeConverter
 60 |             : and then encoded with base64 encoding.
