 |**Name**|Löschfunktionalität|
 |**Beschreibung**|Man kann einen Knopf in der UI drücken um in den Löschmodus zu kommen, und um wieder aus dem Löschmodus rauszukommen. Wenn man im Löschmodus ist, kann man auf einer Leinwand im rechten Bereich gezeichnete Elemente löschen indem man auf sie klickt.|
-|**Akzeptanzkriterium**|Der Knopf für den Löschmodus kann nur gedrückt werden, wenn im rechten Bereich eine Zeichennleinwand vorhanden ist. Wenn man den Knopf drückt ohne im Löschmodus zu sein, verändert sich der Knopf erkennbar und man kommt in den Löschmodus. Drückt man den Knopf, während man im Löschmodus ist, wird der Löschmodus beendet und der Knopf bekommt wieder sein urspüngliches Aussehen. Während man im Löschmodus ist, kann man auf der Leinwand im rechten Bereich Elemente löschen, wenn der Mauszeiger sie berührt während man die Maustaste gedrückt hält. Die Elemente die man löscht verschwinden. Drückt man den Löschknopf während man in einem anderen Modus ist (z.B. Zeichenmodus) wird der andere Modus beendet und man ist im Löschmodus.|

-    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.
