Public Methods

Method	Description
CreateRGBATexture ( int width, int height, byte rgba ) : int	Create a translucent OpenGL texture object from given byte-array of r,g,b,a-triplets. See CreateRGBTexture for more info.
CreateRGBTexture ( int width, int height, byte rgb ) : int	Create an opaque OpenGL texture object from a given byte-array of r,g,b-triplets. Make sure width and height is 1, 2, .., 32, 64, 128, 256 and so on in size since all 3d graphics cards support those dimensions. Not necessarily square. Don't forget to call GL.DeleteTexture(int) when you don't need the texture anymore (eg. when switching levels in your game).
CreateTextureFromBitmap ( Bitmap bitmap ) : int	Create an OpenGL texture (translucent or opaque) from a given Bitmap. 24- and 32-bit bitmaps supported.
CreateTextureFromFile ( string path ) : int	Create an OpenGL texture (translucent or opaque) by loading a bitmap from file. 24- and 32-bit bitmaps supported.
InitTexturing ( ) : void	Initialize OpenGL state to enable alpha-blended texturing. Disable again with GL.Disable(EnableCap.Texture2D). Call this before drawing any texture, when you boot your application, eg. in OnLoad() of GameWindow or Form_Load() if you're building a WinForm app.

Method Details

CreateRGBATexture() public static method

Create a translucent OpenGL texture object from given byte-array of r,g,b,a-triplets. See CreateRGBTexture for more info.

public static CreateRGBATexture ( int width, int height, byte rgba ) : int
width	int
height	int
rgba	byte
return	int

CreateRGBTexture() public static method

Create an opaque OpenGL texture object from a given byte-array of r,g,b-triplets. Make sure width and height is 1, 2, .., 32, 64, 128, 256 and so on in size since all 3d graphics cards support those dimensions. Not necessarily square. Don't forget to call GL.DeleteTexture(int) when you don't need the texture anymore (eg. when switching levels in your game).

rgb	byte
return	int

CreateTextureFromBitmap() public static method

Create an OpenGL texture (translucent or opaque) from a given Bitmap. 24- and 32-bit bitmaps supported.

public static CreateTextureFromBitmap ( Bitmap bitmap ) : int
bitmap	System.Drawing.Bitmap
return	int

CreateTextureFromFile() public static method

Create an OpenGL texture (translucent or opaque) by loading a bitmap from file. 24- and 32-bit bitmaps supported.

InitTexturing() public static method

Initialize OpenGL state to enable alpha-blended texturing. Disable again with GL.Disable(EnableCap.Texture2D). Call this before drawing any texture, when you boot your application, eg. in OnLoad() of GameWindow or Form_Load() if you're building a WinForm app.
