@ -6,10 +6,31 @@ OpenTK 0.9.1 -> 0.9.2
|
|||
+ OpenTK
|
||||
+ Platform
|
||||
+ Added GdiPlus bindings.
|
||||
|
||||
+ Fixed a bug where the KeypardEnter key was reported as Enter on X11.
|
||||
+ Changed the Time X11 struct from int to IntPtr.
|
||||
+ Improved GLControl implementations.
|
||||
+ Graphics
|
||||
+ Added Color4 struct that can hold floating-point ARGB colors.
|
||||
+ Added several new overloads to the GL class. Most deal with OpenTK.Math and System.Drawing.Color interoperation.
|
||||
+ Math
|
||||
+ Added half and double precision structures.
|
||||
+ Added missing ref overloads.
|
||||
+ All structs now implement the IEquatable and ISerializable interfaces.
|
||||
+ General
|
||||
+ Fixed build warnings.
|
||||
+ Eliminated per-frame memory allocations in release builds.
|
||||
|
||||
+ Utilities
|
||||
+ Fonts
|
||||
+ Updated the layout code to use the new GdiPlus bindings.
|
||||
+ Added support for near-, far- and center-aligned text.
|
||||
+ Added support for right-to-left and vertical text (not 100% complete).
|
||||
+ Added support for subpixel antialiasing (requires GL 1.2 or higher).
|
||||
|
||||
+ Examples
|
||||
+ Improved ExampleLauncher behavior on recent Mono/Linux releases.
|
||||
+ Switched to the new TextPrinter implementation.
|
||||
+ Changed background color from SteelBlue to MidnightBlue.

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.
